鉤子(hooks)
Git是在特定事件發生之前或之後執行特定腳本代碼功能(從概念上類比,就與監聽事件、觸發器之類的東西類似)。
Git Hooks就是那些在Git執行特定事件(如commit、push、receive等)後觸發運行的腳本。
gitlab的web hooks跟git hook類似。也是當項目發生提交代碼、提交tag等動作會自動去調用url,這個url可以是更新代碼。或者其他操作。
配置目的:
由於系統屬於後臺接口系統,開發提交完git倉庫後要實時的部署到測試環境,這時候就需要用到gitlab的web hooks自動更新部署了。
客戶端:要自動更新的測試服務器IP:192.168.1.2
服務端:Gitlab服務器IP:192.168.1.1
Gitlab Version: 7.13.0.pre
GitLab-Shell Version: 2.6.3
1、在客戶端上面配置apache配置文件,爲web hooks添加一個接口訪問
#vim /usr/local/apache/conf/httpd.conf
listen 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、在服務端gitlab上面爲客戶端添加gitlab新賬號,然後將生成好的公鑰添加到gitlab好的賬號裏面(profile setting-->SSH Keys -->add ssh key)
#su - webuser
#ssh-keygen -t rsa
進入項目目錄
#cd /path/project
初始化git倉庫
#git clone [email protected]:test/test_api.git
3、在客戶端上面添加接口文件
#vim /www/gitlab_web/index.php
<?php
//作爲接口傳輸的時候認證的密鑰
$valid_token = 'd49dfa762268687eb2ca59498ce852';
//調用接口被允許的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);
//這裏也可以執行自定義的腳本文件update.sh,腳本內容可以自己定義。
//exec("/bin/sh /root/updategit.sh");
exec("cd /path/project;/usr/bin/git pull");
4、訪問接口,測試接口是否成功
http://192.168.1.2:81/?token=d49dfa7622681425fbcbdd687eb2ca59498ce852
5、查看客戶端日誌
#cat /www/gitlab_web/auto_hook.log
=======================================================================
Request on [2015-07-03 14:05:02] from [112.122.112.112]
Data:
=======================================================================
6、在服務端gitlab服務器上面添加web hooks
admin area->projects->test/edit->WEB Hooks->add WEB Hooks
7、提交修改代碼到gitlab倉庫,然後查看日誌、查看測試環境是否更新
#cat /www/gitlab_web/auto_hook.log
Request on [2015-07-03 14:13:37] from [12.123.12.3]
Data: Array

注意事項:
1、配置完成後。調用接口的時候沒有自動更新到測試環境。可以使用apache的運行用戶測試命令是否可以執行成功
#su - webuser
#cd /path/project
#git pull
2、如果apache的用戶無法執行命令或者無法更新git代碼請檢查一下apache用戶的shell。
