Examples to explain PHP implementation of git deployment

Although I have always used git for version management, I have also used git project deployment before, but I have not adhered to this habit. Recently I decided to learn more. The following article mainly introduces you to the method of git deployment in PHP. The tutorial is very detailed through sample code. Friends who need it can refer to it. I hope it can help everyone.

Background

On a small site, it is very convenient to directly use git to deploy PHP code. Your remote site and local repository have a version control to track problems or rollback It's very easy.

Because I work in a small company, the original system still uses traditional ftp upload and deployment. It is too troublesome to deploy and it is not easy to control the online code. I searched for a git deployment tutorial on the Internet, and encountered a lot of pitfalls along the way. Now I am posting the whole process, hoping it can help everyone. I won’t say much below, let’s take a look at the detailed introduction.

Account related

useradd -m git //新增git账号
ssh-keygen //密钥生成,如果已经有了可略过
su git //切换至git账号
cd ~ //切换到git账号根目录
mkdir .ssh //创建.ssh目录
cat /密钥存放目录/xxx.pub >> ~/.ssh/authorized_keys //设置公钥

Be sure to pay attention to permission issues here, otherwise the key login will not be effective. The permissions corresponding to each folder are as follows

.ssh文件夹权限 700
id_rsa 600
id_rsa.pub 644
authorized_keys 600

File permission settings

Put git in the same user group as the user running nginx or apache on the site, such as www

vim /etc/passwd Find the git account and www account, and put the git account The group identity is changed to be consistent with the www group identity

The site owner is set to git, and the user group is set to www //Assume that nginx and git both belong to the www user group

Directory permissions are set to 775, and file permissions are set to 664

Warehouse code

Server side

cd 站点目录
git init //初始化目录

git configuration

git config receive.denyCurrentBranch ignore //设置仓库接受代码提交

Set sudo password-free

vim /etc/sudoers
# Defaults secure_path 中若没有你要的命令,要注意添加
# php的命令默认需要在 secure_path最后面添加 :/usr/local/php/bin"
在 root ALL=(ALL) ALL 下面一行添加
git ALL=(ALL) NOPASSWD:ALL 
# 保存退出 ,这样针对laravel 要重启队列命令就可以使用了.
# sudo php artisan queue:restart

Hook settings

cd .git/hooks //切换至站点钩子目录
touch post-receive //创建接收提交时钩子
// 钩子文件内容如下:
#!/bin/sh
# 设置账号创建文件的默认权限
umask 002 
unset GIT_DIR
cd ..
git checkout -f
# 执行PHP钩子逻辑
/usr/bin/curl http(s)://域名/钩子文字位置/hook.php
# 如果有使用laravel队列则需要重启队列进程,让新代码生效
# sudo php artisan queue:restart
exit 0

hook.php content

<?php
/**
 * git上传执行钩子
 */
//TODO 安全限制
//TODO 其他钩子行为
// 清除opcache
if (version_compare(PHP_VERSION, &#39;5.5.0&#39;, &#39;>=')) {
 opcache_reset();
}

Increase hook executable permissions

chmod a+x .git/hooks/post-receive

Local code

git remote add 远程仓库名称 ssh://git@IP地址:/站点目录 //添加远程仓库
git push 远程仓库名称 master

Special attention

The image directory uploaded by the user must be ignored, otherwise it may be deleted when untracked files are cleared Deleting this part of the file will cause catastrophic results
