I have created a makefile as below:
.PHONY: all update-repo dependency-install unit-tests file-permission
all: update-repo dependency-install unit-tests file-permission
update-repo:
git reset --hard
git pull origin master
dependency-install:
composer update
unit-tests:
vendor/bin/phpunit
file-permission:
chmod 777 application/logs
chmod 777 application/cache
chmod 777 application/models/proxies
Now trying to execute it from php with following script:
echo shell_exec("make");
Not that both files are given 777 permission.
Now I am trying to execute those make commands by executing the php script from web url. After executing start, I only get following output:
git reset --hard
HEAD is now at 758a275 test commit
git pull origin master
So, for some reason other commands aren't being executed. Does anyone have any clue why? Thanks.
This is a permissions issue. Make sure the errors are also going to stdout to find out what is going wrong:
echo shell_exec("make 2>&1");
More info: In the shell, what does " 2>&1 " mean?

What I am trying to do
I have a git repository on bitbucket. After pushing to the repository from my local machine I want to automatically pull the master branch to my webspace.
What I have done so far
I connected to my server using ssh, created the ssh key and registered the public key on github.
I created a .sh script which pulls the master branch using ssh - so far so god - everything works when I run the script from the command line/putty
What is the problem
I want to trigger the .sh script with a webhook on bitbucket (I can give an url). For that purpose I created a .php file in my webspace:
<?php
$output = shell_exec('./deploy.sh 2>&1');
echo $output;
my .sh script looks like this:
#!/bin/bash
git pull git#bitbucket.org:dualmeta/test.git master
As already said, running the .sh script with putty works perfectly fine. However if I enter the url to the .php file in my browser it gives me an error:
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I already did some reserach and found that many people have the exact same problem. However in my case i do not have root/sudo access because it is a rented webspace and not my own vServer.
Is there any chance getting this to work?
You must add access www-data or apache user to your git directory.
chown -R apache:apache git_directory
or
chown -R www-data:www-data git_directory
or
chmod o+rw -R git_directory
Use this too :
git config credential.helper store
I am trying to deploy a Symfony2 PHP project on Ubuntu 15.10 with MagePHP, but it always asks me for the SSH users password when executing:
sudo php vendor/andres-montanez/magallanes/bin/mage deploy to:staging
When checking the log I can see it stops at this command:
ssh -p 22 -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no ssh-user#my-domain.com "sh -c \"mkdir -p /customers/489176_10999/websites/my_company/symfony/staging/releases/20160902094526\""
Executing this command by itself works fine (so the server accepts the ssh key), but from within the context of the deployment script it doesn't.
I am quite puzzled by this, since both commands are run from the same directory. Any ideas how I can make this work?
try running the deploy with sudo.
Regards!
Since the file has been located under /var/www the ssh-agent had no access to the key files, since they were stored under the user directory. Moving the entire project inside the user directory fixed this issue.
I have create a webhook in my github repository which post on the hook url on my live server to run pull command for update my repo files on the server.
The problem is the hook file which i have created is in the /var/www/site/web/hookfile.php (the post request is going there. i am getting the body response also)
and my repo files are in /var/www/git-repo/
its not updating the git-repo when i push anything to my github repository.
I run this command using terminal and its working.
cd /var/www/git-repo && git pull
But through my php file its not working
shell_exec('cd /var/www/git-repo && git pull')
shell_exec() fail silently because only report STDOUT and not STDERR.
Try with:
echo shell_exec("cd /var/www/git-repo && /full/path/to/bin/git pull 2>&1");
Normally is a permission error, and could be fixed adding permission to the user that execute php (apache?)
chown -R www-agent:www-agent repository/
But could be also a connection error to the remote repository (authentication, ssh-keys, ...).
First of all in your php file run a test against your server instance to get any error messages output on screen because the exec() family of functions simply fail silently and only report STDOUT and not STDERR:
echo shell_exec("cd /website/root/htdocs && git checkout . && git status 2>&1");
In my case this threw an error that it could not find git command due to lack of binary path defined for apache user. Therefore, a full path needs to be provided to git's binary. It can be obtained by finding it manually or running in shell:
'which git'
It returned (further called YOU_FULL_GIT_BINARY_PATH_HERE):
/usr/local/git/bin/git
A full path with git command e.g. '/usr/local/git/bin/git status' now runs git commands nicely.
Another thing is to ensure your web server user has enough permissions to read/write to your repo folder/files. I have set mine to be owned by the apache user (Centos 6.8; other releases might be www:www or www-data:www-data etc.):
chown -R apache:apache YOUR_WEB_OR_REPO_FOLDER
In order to ensure any newly added files inherit correct permissions run:
chmod -R g+s YOUR_WEB_OR_REPO_FOLDER
The above should get your script to run commands now. Though it doesn't overcome git password prompt to use 'git pull' command for a git user set in YOUR_WEB_OR_REPO_FOLDER/.git/config file. Running below command inside repo:
git config credential.helper store
command will prompt for password and let you store it locally. Please note your stored password will be unencrypted and protected only by file system e.g. in /root/.git-credentials. This will allow to run 'git pull' without prompting for password.
It's not ideal for my fully automated continuous integration environment deploying test VPS on demand as it requires to manually enter git user (defined in repo's .git/config git) password at least once.
Since my environment should always run on code from remote's origin/master copy I am also running
/YOU_FULL_GIT_BINARY_PATH_HERE/git checkout .
before invoking 'git pull' to ensure any local changes are lost forever alternatively do a hard reset instead using:
/YOU_FULL_GIT_BINARY_PATH_HERE/git fetch origin
/YOU_FULL_GIT_BINARY_PATH_HERE/git reset --hard origin/master
I'm running in trouble with my new VPS. I created a file pull.php with this code in my GIT folder:
<?php
$output = shell_exec('git pull');
echo "<pre>$output</pre>";
?>
It was working fine on my shared hosting but on my VPS it's return null and no 'pull' command executed. When I change the command 'git pull' to 'git status' it's show result :
On branch master
Your branch is up-to-date with 'origin/master'.
Untracked files: (use "git add ..." to include in what will be
committed)
info.php pull.php test.txt
nothing added to commit but untracked files present (use "git add" to
track)
My folder chmod to 777 and php seems can write on it properly. 'git pull' on SSH's fine. My server : Ubuntu 14.x, Apache2, php5
I would very much appreciate any help!
Probably git pull is throwing an error but the errors are not printed by default. To fix this change this line
$output = shell_exec('git pull');
for this one:
$output = shell_exec('git pull 2>&1');
I find it weird you get no output nothing...
do you have root access?
try as root in the right folder: sudo -u apache git pull
see if you get any output then.
You should add following line to /etc/sudoers
apache2 ALL=(root) NOPASSWD: /usr/bin/git
This allows apache to execute git as root and therefore access the files
then call git command (proper executable location is preferred)
shell_exec('sudo /usr/bin/git pull /path/to/your/repo');
I'm trying to setup phing to work with travis-ci, but I can't get it to run a setup script to get all the dependencies installed.
My .travis.yml file is:
language: php
php:
- 5.2
script: ./.travis-phing.sh
In travis, I get the error:
/home/travis/build.sh: line 105: ./.travis-phing.sh: Permission denied
What is causing that?
Solved
The script to be set to execute. I used:
chmod a+x .travis-phing.sh
Then simply commit, and push back to github.
Run the script using bash
Another option would be to run the script using bash, this would omit the need to modify the files' permissions.
bash path/to/file.sh
Alternatively:
sh path/to/file.sh
Note that
In this case you're not executing the script itself, you're executing bash or sh which then runs the script. Therefore the script does not need to be executable.
Make sense?
I've found this solution incredibly useful myself. I'm mainly running node & npm projects on travis-ci, those builds make use of the npm test command which you can configure to be anything.
I'm order to modify file permission I need to use sudo chmod ... on my local machine. But you can't always use sudo on travis-ci.
sh file.sh allows me to run my tests both locally and on travis-ci without having to manually update permissions.
