I'm trying to setup Nginx as a reverse proxy for Apache, from what I've read, it allows nginx to serve static content and Apache handles the backend PHP stuff, but i cant seem to get Apache to render.
I'm on CentOS7, i installed nginx just using yum install nginx, then i installed PHP7.2 by doing the following;
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum-config-manager --enable remi-php72
yum install php72 php72-php-fpm php72-php-mysqlnd php72-php-opcache php72-php-xml php72-php-xmlrpc php72-php-gd php72-php-mbstring php72-php-json
running php72 -v gives me
PHP 7.2.13 (cli) (built: Dec 8 2018 10:59:58) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.2.13, Copyright (c) 1999-2018, by Zend
Technologies
I then ran
ln -s /usr/bin/php72 /usr/bin/php
As yum installs the command as php72
I edited nginx.conf and changed the user from nginx to apache and changed the server block to;
server {
listen 80 default;
server_name 108.xxx.xxx.xxx;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
root /var/www/html;
proxy_pass http://127.0.0.1:8080/;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
I also added /etc/nginx/conf.d/proxy.conf with the following;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
I then installed Apache2 via yum install httpd.
I have then edited the Apache2 httpd.conf file;
- Listen 80
+ Listen 127.0.0.1:8080
I also edited /etc/opt/remi/php72/php-fpm.d/www.conf and changed user and group to apache and also
listen = /var/run/php-fpm.sock
listen.owner = apache
listen.group = apache
listen.mode = 0660
These are the only changes I have made.
I added 2 files to /var/www/html, index.html and index.php ... The index.html works perfect, and when i check with browserspy, it says that it is being served by Nginx, excellent. But when I run the index.php file it displays the actual php code and doesn't render it.
I have never really worked with Apache2 before, so i am unsure of how to look for the error. When i loook in Apache2 modules directory i can't find any PHP modules
ls -lah /etc/httpd/modules/ | grep php
returns nothing at all.
Any help would be really greatful, I have been looking for a solution for days.
Thanks
Nginx can definitely execute PHP scripts without the need of proxying back to Apache.
The reason why you're seeing just the PHP code rather than the website, is because your Apache configuration likely does not have the PHP module enabled.
You can do this by running yum --enablerepo=remi install php and running service apache2 restart to restart the server with the new configuration.
Installing the base PHP packages also adds the required modules for PHP files to be executed by Apache.
This should allow your server to start executing the PHP scripts as you expect.
If you'd like to instead run your PHP website via Nginx instead, you'll need to make some slight modifications to your Nginx configuration.
Firstly, you'll need to replace your location block to use the files on your local filesystem and then point any .php file to run using PHP-FPM.
location / {
root /var/www/html;
try_files $uri $uri/ =404;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
So we're building a web application in PHP and we're trying to make requests to an external API. Problem is that we're getting a curl error:
cURL error 7: Failed to connect to external.api.com port 443: No route to host
A little bit of background now.
We're making requests using Guzzle.
We're hosting on Apache, which is running on a Linux machine and we're also using SSL.
The API is also using SSL, therefore the port 443 in error message.
The HTTP requests include a certificate for authentication.
I've managed to get it running on two different development environments but not on the production one. I suspect the problem is in the configuration of Apache, as if we haven't made it available to make requests to certain IP or port. I have no idea how to check it. I've read that I might have to change the file /etc/network/interface yet I haven't found any info on what to write there.
I've also read I have to run $ netstat -rn for answers yet I'm not sure what to look there.
EDIT:
Can't even make a simple get request without any parameters and anything.
Yet I can make requests to https://google.com and https://facebook.com. Will write more in a few.
After a lot of debugging and testing all of my code I contacted the service, whose API I was trying to consume.
They were an European service provider and they had whitelisted European IP's. Our production server was in the USA and after they whitelisted our IP, everything worked.
It worked for me for apache (httpd)
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
netstat -aln | grep 443 will show if your webserver is listening on that port.
Depending on which webserver you have installed your configuration file, for the site will be at /etc/nginx/sites-available/default, /etc/nginx/sites-available/yourSite, /etc/nginx/nginx.conf or some other similar paths for apache.
Wherever it is located, your configuration file should contain something like the following:
server {
listen 80;
listen 443 ssl;
server_name yourSite.com;
root "/path/to/yourSite";
index index.html index.htm index.php;
charset utf-8;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
access_log off;
error_log /path/to/webserver/youSite.error.log error;
sendfile off;
client_max_body_size 100m;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors off;
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
}
location ~ /\.ht {
deny all;
}
ssl_certificate /path/to/yourSite.crt;
ssl_certificate_key /path/to/yourSite.key;
}
After changing this file make sure to sudo service nginx reload or sudo service nginx restart (or the relative apache command).
sudo service nginx configtest or sudo nginx -t will help with debugging the config file.
After searching for about a whole day I found that the problem was in the iptables rules.
In my case the solution was to restore the iptables rules as follows:
create a file containing the following text:
*filter
:INPUT ACCEPT [10128:1310789]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [9631:1361545]
COMMIT*
run the command: sudo iptables-restore < /path/to/your/previously/created/file
This will hopefully fix your problem if it is an iptables issue.
today I hava face up the same question, like that
I use curl http://localhost:8080 to check my tomcat can work or not
And it's error Failed to connect to ::1: No route to host
Finally I hava solve it.Obviously, it's the problem of your Apache tomcat.
So you must check your logs firstly. If you found your port was used, find that course and kill it. Then restart your tomcat.
find the course by port: netstan -lnp | grep port
kill course: kill -9 ****

I'm trying to configure the tool Monit to restart Nginx or PHP-FPM if ever there is a problem. It is correctly monitoring Nginx however Monit says it will "Not Monitor". Apparently I'm having it check the wrong location.
Here is my Nginx configuration for PHP-FPM that is running on a socket:
location ~ \.php$ { ## Execute PHP scripts
if (!-e $request_filename) { rewrite / /index.php last; } ## Catch 404s that try_files miss
expires off; ## Do not cache dynamic content
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params; ## See /etc/nginx/fastcgi_params
fastcgi_keep_conn on; #hhvm param
}
Here is my Monit configuration for both Nginx and PHP-FPM:
## Check Nginx
check process nginx with pidfile /var/run/nginx.pid
start program = "/etc/init.d/nginx start"
stop program = "/etc/init.d/nginx stop"
## Check PHP-FPM
check process php-fpm with pidfile /var/run/php-fpm/php-fpm.pid
group www-data #change accordingly
start program = "/etc/init.d/php5-fpm start"
stop program = "/etc/init.d/php5-fpm stop"
if failed unixsocket /var/run/php-fpm/php-fpm.sock then restart
if 3 restarts within 5 cycles then timeout
I went with the suggested start and stop recommendations despite always restarting with "service php5-fpm restart".
My group - according to /etc/php5/fpm/pool.d/www.conf is "group = www-data". Any suggestions?
Ok, I was able to solve it myself. There were a number of problems. "php5" needed to replace almost every instance of "php". The bad connection I was receiving was referring to the unixsocket so I had to update that as well. Also the new PID location changed it looks like with PHP5-FPM. Here is the final configuration.
## Check PHP-FPM
check process php5-fpm with pidfile /var/run/php5-fpm.pid
group www-data #change accordingly
start program = "/etc/init.d/php5-fpm start"
stop program = "/etc/init.d/php5-fpm stop"
if failed unixsocket /var/run/php5-fpm.sock then restart
if 3 restarts within 5 cycles then timeout
I have a Debian 7.3 installation in a VM that I am practising installing Nginx and php5-fpm on. I got the Nginx working, by assigning it a manual port of :8080 and that points to /var/www/ for data and in that directory is an index.html and info.php file.
The config file for my Nginx is located at /etc/nginx/conf.d/default.conf and looks like this:
server {
listen 8080;
root /var/www;
index index.php index.html index.htm;
server_name localhost;
location / {
try_files $uri $uri/ /index.html;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
allow ::1;
deny all;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
#fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
I have tried changing fastcgi_pass both ways:
fastcgi_pass 127.0.0.1:9000;
and also as:
fastcgi_pass unix:/var/run/php5-fpm.sock;
In my /etc/php5/fpm/pool.d/www.conf file I have the following configuration:
[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000
;listen = /var/run/php5-fpm.sock
Here too, I have uncommented the line to match in the Nginx default.conf file.
In my php.ini file I have edited it so that it shows cgi.fix_pathinfo = 0 as required by most of the guides I have seen.
When I try to load nginx, it runs OK. When I try to run php5-fpm this is what happens:
root#debianx86:/# /etc/init.d/php5-fpm status
[FAIL] php5-fpm is not running ... failed!
root#debianx86:/# /etc/init.d/php5-fpm reload
[ ok ] Reloading PHP5 FastCGI Process Manager: php5-fpm.
root#debianx86:/# /etc/init.d/php5-fpm restart
[FAIL] Restarting PHP5 FastCGI Process Manager: php5-fpm failed!
root#debianx86:/# /etc/init.d/php5-fpm start
root#debianx86:/# /etc/init.d/php5-fpm status
[FAIL] php5-fpm is not running ... failed!
root#debianx86:/#
I then open up any of the browsers on my VM and point them to either 127.0.0.1:8080 or localhost:8080 and I get the custom index.html loading that I made and it works! So I then try to load theinfo.php file and I get presented with a 404 Not Found - nginx/1.4.4.
I don't understand what I'm doing wrong. Is there something I'm missing from all this?
I installed nginx from sudo apt-get -y install nginx and sudo apt-get -y install php5-fpm too. Any dependencies they required would have been installed along with that.
Is there a script that I can run on a fresh install of Debian 7.3 that someone has got that will install it properly for me, and make all the modifications so that nginx and php5-fpm are up and running? I've looked over many of the websites with the instructions and I seem to be doing pretty much everything they do, except for the default-sites and enabled-sites, as neither of those folders exist for me, and I don't want to run my virtual hosts like that. I will run them with their own servers listed in the default.conf file.
EDIT: I have even tried following this article at DigitalOcean and it still doesn't work.
EDIT #2: I also did chown -R www-data:www-data /var/www to ensure that the user and group match the information in the www.conf file. I also tried by changing it back to the original root:root specs too. Still nothing.
I think maybe port 9000 is already being used, so php5-fpm can't bind with that port and fails to start.
in the fpm pool settings swap the line of port 9000 with the line with the sock file, then try to start php5-fpm like you were doing, if it works then all you need is to update the nginx configuratuin to proxy pass to the sock file instead of the port.
Configuration

Before I write anything else, I'd like to state that I've checked both nginx 502 bad gateway and Nginx + PHP-FPM 502 Bad Gateway threads, which unfortunately haven't helped me in this regard.
The issue appears to be rather common: a misconfiguration of nginx or php-fpm can lead to a 502 Bad Gateway error, which is something that I haven't been able to get rid of. Note that this appears even when I go to my domain root, without specifying any particular directory.
I'm running an Amazon EC2 webserver, with port 9000 enabled, port 80 open, etc.
The question in particular is, how can I get rid of this nasty error? Or, better yet, how can I get php5-fpm to actually work.
What I Have Attempted so Far
Mostly consistent editing of configuration files, notably php-fpm.conf and nginx.conf.
i. php-fpm.conf
I've added the following, which hasn't quite helped much:
;;;;;;;;;;;;;
; Fpm Start ;
;;;;;;;;;;;;;
;pm.start_servers = 20
;pm.min_spare_servers = 5
;pm.max_spare_servers = 35
Now, afterward I tried including my configuration files:
include=/etc/php5/fpm/*.conf
Which only screwed me even further.

ii. nginx.conf
In all honesty this configuration is a smattering of a few websites I've visited, but I can tell you that before this 502 Bad Gateway business, the server was running fine (without PHP working. Period.).
The issue primarily lies in the fact that something is terribly, terribly wrong. And now, when I try to do a service php5-fpm restart, it hangs in what I'm guessing is an infinite loop or something, which I can't even CTRL-C out of.

If anyone finds this page by encountering the same problem I had, I found the answer here.
For those of you who can't be bothered to click and work it out for themselves... ;)
The Condition:
Ubuntu or Debian server with NGINX and PHP 5.3 works fine but upgrading PHP to 5.4 gives 502 Bad Gateway errors. Looking for services running on port 9000 (typically running netstat -lp or similar) returns nothing.
The fix:
Open /etc/php5/fpm/pool.d/www.conf and make a note of the 'listen' parameter (in my case /var/run/php5-fpm.sock):
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php5-fpm.sock
and replace the fastcgi_pass variable in your vhost with the location you just noted.
So this sample symfony2 configuration (taken from here):
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
becomes this:
# pass the PHP scripts to FastCGI server at /var/run/php5-fpm.sock
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
Then restart nginx:
sudo /etc/init.d/nginx restart
Note: replace ~ ^/(app|app_dev)\.php(/|$) { with ~ ^/index\.php(/|$) { if you're not on SF2**
Hope this saves someone a little bit of time :)
Edit
Of course, you could change the listen = /var/run/php5-fpm.sock to listen = 127.0.0.1:9000 in /etc/php5/fpm/pool.d/www.conf then restart php5-fpm (which would save you from having to change your vhosts), but you have to assume they changed php5-fpm to run through a socket rather than listening on port 9000 for a reason.
Edit2
If you're still experiencing 502 error see this answer.
Try setting these values, it solves problem in fast-cgi
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
I made all this similar tweaks, but from time to time I was getting 501/502 errors (daily).
This are my settings on /etc/php5/fpm/pool.d/www.conf to avoid 501 and 502 nginx errors…
The server has 16Gb RAM. This configuration is for a 8Gb RAM server so…
sudo nano /etc/php5/fpm/pool.d/www.conf
then set the following values for
pm.max_children = 70
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 35
pm.max_requests = 500
After this changes restart php-fpm
sudo service php-fpm restart
If you met the problem after upgrading php-fpm like me, try this:
open /etc/php5/fpm/pool.d/www.conf
uncomment the following lines:
listen.owner = www-data
listen.group = www-data
listen.mode = 0666
then restart php-fpm.
Don't forget that php-fpm is a service. After installing it, make sure you start it:
# service php-fpm start
# chkconfig php-fpm on
For anyone else struggling to get to the bottom of this, I tried adjusting timeouts as suggested as I didn't want to stop using Unix sockets...after lots of troubleshooting and not much to go on I found that this issue was being caused by the APC extension that I'd enabled in php-fpm a few months back. Disabling this extension resolved the intermittent 502 errors, easiest way to do this was by commenting out the following line :
;extension = apc.so
This did the trick for me!
You should see the error log.
By default, its location is in /var/log/nginx/error.log
In my case, 502 get way because of:

When we know exactly what is wrong, then fix it. For these error, just modify the buffer:
fastcgi_buffers 16 512k;
fastcgi_buffer_size 512k;
The port was changed to 9001 in 5.4, just changing the port from 9000 to 9001 in the nginx conf and in php-fpm configuration worked for me.
Hope this tip will save someone else's life. In my case the problem was that I ran out of memory, but only slightly, was hard to think about it. Wasted 3hrs on that. I recommend running:
sudo htop
or
sudo free -m
...along with running problematic requests on the server to see if your memory doesn't run out. And if it does like in my case, you need to create swap file (unless you already have one).
I have followed this tutorial to create swap file on Ubuntu Server 14.04 and it worked just fine:
http://www.cyberciti.biz/faq/ubuntu-linux-create-add-swap-file/
I've also found this error can be caused when writing json_encoded() data to MySQL. To get around it I base64_encode() the JSON. Please not that when decoded, the JSON encoding can change values. Nb. 24 can become 24.00
All right after trying every solution on the web I ended up figuare out the issue using very simple method , first I cheked php-fpm err log
cat /var/log/php5-fpm.log
and the most repeated error was
" WARNING: [pool www] server reached pm.max_children setting (5), consider raising it "
I edit PHP-fpm pools setting
nano /etc/php5/fpm/pool.d/www.conf
I chenged This Line
pm.max_children = 5
To new Value
pm.max_children = 10
BTW I'm using low end VPS with 128MB ram As everyone else I was thinkin redusing pm.max_children will make my server run faster consume less memory , but the setting we using were too low tho even start PHP-fpm process .
I hope this help others since I found this after 24 hour testing and failing , ever my webhost support were not able to solve the issue .
I'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.
Before messing with Nginx config, try to disable ChromePHP first.
1 - Open app/config/config_dev.yml
2 - Comment these lines:
chromephp:
type: chromephp
level: info
ChromePHP pack the debug info json-encoded in the X-ChromePhp-Data header, which is too big for the default config of nginx with fastcgi.
In your NGINX vhost file, in location block which processes your PHP files (usually location ~ \.php$ {) through FastCGI, make sure you have next lines:
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
After that don't forget to restart fpm and nginx.
Additional:
NGINX vhost paths
/etc/nginx/sites-enabled/ - Linux
'/usr/local/etc/nginx/sites-enabled/' - Mac
Restart NGINX:
sudo service nginx restart - Linux
brew service restart nginx - Mac
Restart FPM:
Determine fpm process name:
- systemctl list-unit-files | grep fpm - Linux
- brew services list | grep php - Mac
and then restart it with:
sudo service <service-name> restart - Linux
brew services restart <service-name> - Mac
Maybe this answer will help:
nginx error connect to php5-fpm.sock failed (13: Permission denied)
The solution was to replace www-data with nginx in /var/www/php/fpm/pool.d/www.conf
And respectively modify the socket credentials:
$ sudo chmod nginx:nginx /var/run/php/php7.2-fpm.sock
