git自动化部属

gitlab和github都支持通过webhook自动部署，本文使用gitlab+webhook的方式实现自动化部署项目。

1、填写回调URL
随便在gitlab上找一个项目，填写回调URL，如果有Push请求，gitlab会自动回调你填写的这个地址。
回调地址

2、开发服务器配置
一般php是通过php-fpm来运行，而php-fpm一般由apache用户来运行。确保clone下来的仓库权限比如为apache.
可通过如下命令进行修改

1
# chown apache:apache you_project * -R

创建apache用户的.ssh文件

1
sudo -u apache ssh-keygen -t rsa

3、测试
在本地commit一个提交.

1
2
# git ci -am 'test webhook'
# git push origin dev

在开发服务器上查看日志

1
# tail -f /var/log/php-fpm/www-error.log

可以看到

    [0] => From git.xxx.cn:your_project/project_name
    [1] =>  * branch            master     -> FETCH_HEAD
    [2] => Updating c02949b..f8c52c5
    [3] => Fast-forward

    [5] =>  1 files changed, 42 insertions(+), 0 deletions(-)
    [6] =>  create mode 100644 webhook.php
)

搞定！
