钩子(hooks)
Git是在特定事件发生之前或之后执行特定脚本代码功能(从概念上类比,就与监听事件、触发器之类的东西类似)。
Git Hooks就是那些在Git执行特定事件(如commit、push、receive等)后触发运行的脚本。
gitlab的web hooks跟git hook类似。也是当项目发生提交代码、提交tag等动作会自动去调用url,这个url可以是更新代码。或者其他操作。

配置目的:

由于系统属于后台接口系统,开发提交完git仓库后要实时的部署到测试环境,这时候就需要用到gitlab的web hooks自动更新部署了。

客户端:要自动更新的测试服务器IP:192.168.1.2

服务端:Gitlab服务器IP:192.168.1.1

Gitlab Version:     7.13.0.pre

GitLab-Shell  Version:     2.6.3



1、在客户端上面配置apache配置文件,为web hooks添加一个接口访问
#vim /usr/local/apache/conf/httpd.conf

listen 81

          ServerAdmin localhost
          DocumentRoot "/www/gitlab_web"
      
            Options -Indexes +FollowSymLinks
            AllowOverride None
            Order allow,deny
            Allow from all
         

       RewriteEngine on


2、在服务端gitlab上面为客户端添加gitlab新账号,然后将生成好的公钥添加到gitlab好的账号里面(profile setting-->SSH  Keys -->add ssh key)

#su - webuser

#ssh-keygen -t rsa

进入项目目录
#cd /path/project

初始化git仓库 
#git clone [email protected]:test/test_api.git


3、在客户端上面添加接口文件

#vim /www/gitlab_web/index.php

//作为接口传输的时候认证的密钥
$valid_token = 'd49dfa762268687eb2ca59498ce852';
//调用接口被允许的ip地址
$valid_ip = array('192.168.1.1','10.17.10.175','112.112.112.112');
$client_token = $_GET['token'];
$client_ip = $_SERVER['REMOTE_ADDR'];
$fs = fopen('./auto_hook.log', 'a');
fwrite($fs, 'Request on ['.date("Y-m-d H:i:s").'] from ['.$client_ip.']'.PHP_EOL);
if ($client_token !== $valid_token)
{
    echo "error 10001";
    fwrite($fs, "Invalid token [{$client_token}]".PHP_EOL);
    exit(0);
}
if ( ! in_array($client_ip, $valid_ip))
{
    echo "error 10002";
    fwrite($fs, "Invalid ip [{$client_ip}]".PHP_EOL);
    exit(0);
}
$json = file_get_contents('php://input');
$data = json_decode($json, true);
fwrite($fs, 'Data: '.print_r($data, true).PHP_EOL);
fwrite($fs, '======================================================================='.PHP_EOL);
$fs and fclose($fs);
//这里也可以执行自定义的脚本文件update.sh,脚本内容可以自己定义。
//exec("/bin/sh /root/updategit.sh");
exec("cd  /path/project;/usr/bin/git pull");



4、访问接口,测试接口是否成功

http://192.168.1.2:81/?token=d49dfa7622681425fbcbdd687eb2ca59498ce852


5、查看客户端日志

#cat /www/gitlab_web/auto_hook.log

=======================================================================
Request on [2015-07-03 14:05:02] from [112.122.112.112]
Data: 
=======================================================================


6、在服务端gitlab服务器上面添加web hooks

admin area->projects->test/edit->WEB Hooks->add WEB Hooks

7、提交修改代码到gitlab仓库,然后查看日志、查看测试环境是否更新

#cat /www/gitlab_web/auto_hook.log

Request on [2015-07-03 14:13:37] from [12.123.12.3]
Data: Array
(
    [object_kind] => push
    [before] => e5988b5dce7a038
    [after] => d8ce92ac4ab4ba046dd
    [ref] => refs/heads/master
    [checkout_sha] => d8ceefd5c4ab4ba046dd
    [message] => 
    [user_id] => 7
    [user_name] => test
    [user_email] => [email protected]
    [project_id] => 3
    [repository] => Array
        (
            [name] => test_api
            [url] => [email protected]:test/test.api
            [description] => test.com product code
            [homepage] => http://xx./test_api
            [git_http_url] => http://xx./test_api 
            [git_ssh_url] => [email protected]:test.git
            [visibility_level] => 10
        )

    [commits] => Array
        (
            [0] => Array
                (
                    [id] => d8cec4ab4ba046dd
                    [message] => 测试gitlab的web hook接口。

                    [timestamp] => 2015-07-03T14:13:51+08:00
                    [url] => http://xxxx/test_api/commit/d8ce95c4ab4ba046dd
                    [author] => Array
                        (
                            [name] => test
                            [email] => [email protected]
                        )

                )

        )

    [total_commits_count] => 1
)


注意事项:

1、配置完成后。调用接口的时候没有自动更新到测试环境。可以使用apache的运行用户测试命令是否可以执行成功

#su - webuser

#cd /path/project

#git pull


2、如果apache的用户无法执行命令或者无法更新git代码请检查一下apache用户的shell。
