怎么自动化一键部署PHP项目

如何自动化一键部署PHP项目

1.技能需求

完成自动化一键部署PHP需要：PHP（略懂），Shell（略懂），git（略懂）

2.最终效果

输入密码，回车，5~20秒后（一般一天一次持续交付，部署的代码量和sql脚本都不会很大）

执行产生的log文件、数据库备份和数据库执行结果在这里：

 

3.如何做的Part1-Git

首先要有一个VCS系统，我这里用的是Git客户端，本地和服务器都是。（没用过Git可以看这篇文章，我就是用它入门的）

这里只用到Git pull，其他的如svn等，都是一样的。

Linux服务器装Git客户端，我有一个脚本：

 

<span style="color: #000000;">#Git related</span><span style="color: #0000ff;">yum</span> -y <span style="color: #0000ff;">install</span> curl-devel expat-devel gettext-devel openssl-devel zlib-<span style="color: #000000;">devel#Git</span><span style="color: #0000ff;">yum</span> -y <span style="color: #0000ff;">install</span> git-<span style="color: #000000;">coregit config </span>--global user.name <span style="color: #800000;">"</span><span style="color: #800000;">YourName</span><span style="color: #800000;">"</span><span style="color: #000000;">git config </span>--<span style="color: #000000;">global user.email YourMail</span><span style="color: #0000ff;">echo</span> <span style="color: #800000;">"</span><span style="color: #800000;">Git installation completed.</span><span style="color: #800000;">"</span>

 

 

 

这一段代码失败率很高，原因不详，我Linux也是初级，如果失败可以尝试一句一句手打，还不行可能是Linux的yum源有问题，没有git下载地址什么的。

 

安装好之后运行git --version，像这样：

[[email protected] tmp]# git --version

git version 1.8.2.1

就OK。接下来服务器一个合适的位置git clone 下来代码库。就可以了。

 

4.如何做的Part2-Shell

 

基本工作都在这里，包含几部分内容：更新代码，备份代码，部署代码，修改项目config信息，备份数据库，跑数据库脚本。

大概的代码在下面，我删了一些项目相关的，你也可以根据自己的需求删减或添加：

现在运行这个脚本测试一下，新手注意权限问题，大多shell脚本的失败都是权限问题。

 

其实现在已经算是完成了，log和sql都在/tmp中可供查看，但是我们是要连登陆服务器这一步都要省略掉的变态，所以我们还要研究一下apache。

 

5.如何做的Part3-PHP

想要让php运行shell脚本需要以下步骤，我也是从跟别人学的，这里说一下思路，具体看一看这篇文章

你需要一个执行shell的用户（EXECUTOR），在httpd.conf里面把apache运行用户改成EXECUTOR，在sudo里面给EXECUTOR加上无需密码的运行权限。

PHP示例代码如下：

密码可以在php或者shell中检查，我这里输入的是数据库密码。

 

 

6.总结

麻烦是麻烦了点，但是完成之后当你每天部署4、5次，加起来只用了2分钟的时候，你就能感觉到慢慢的成就感了。
