钩子（hooks）
hooks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类型。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
步骤如下：
- 在客户端上配置Apache配置文件，为web hooks添加一个访问接口
#vim /usr/local/apache/conf/httpd.conflisten 81<VirtualHost *:81> ?????????ServerAdmin localhost ?????????DocumentRoot "/www/gitlab_web" ??????<Directory "/www/gitlab_web"> ???????????Options -Indexes +FollowSymLinks ???????????AllowOverride None ???????????Order allow,deny ???????????Allow from all ?????????</Directory> ??????RewriteEngine on</VirtualHost>
2.在服务端gitlab上面为客户端添加gitlab新账号，然后将生产的公钥添加到gitl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 git@192.168.1.1:test/test_api.git
3.在客户端上面添加接口文件
#vim /www/gitlab_web/index.php<?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.logRequest 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] => test@qq.com ???[project_id] => 3 ???[repository] => Array ???????( ???????????[name] => test_api ???????????[url] => git@192.168.1.1:test/test.api ???????????[description] => test.com product code ???????????[homepage] => http://xx./test_api ???????????[git_http_url] => http://xx./test_api ????????????[git_ssh_url] => git@112.23.23.1: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] => test@qq.com ???????????????????????) ???????????????) ???????) ???[total_commits_count] => 1)
PS: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更新git代码，请检查一下Apache的用户的shell以及PHP是否支持exec调用shell命令。
