类型

coding 钩子

github 钩子

环境

服务端:阿里云虚拟主机(Ubuntu16.04)

coding 自动部署 WebHook3.0

windows 10 开发环境

部署

服务器虚拟主机配置

coding 代码托管配置

本地代码提交

服务端配置

1、创建web服务器用户目录

这里以www用户为例,不同的环境请根据自己环境自行修改

sudo mkdir /var/www/.ssh
sudo chown -R www:www /var/www/.ssh/

2、生成公钥(两个)

git用户公钥(个人公钥通用)

部署公钥(部署公钥用以部署项目, 只针对项目)

其实配置一个个人公钥就可以,也就是通用公钥了

3、用户公钥

用于git clone时认证权限

ssh-keygen -t rsa -C "Tinywan@gmail.com"
# 然后一直回车就行
# 生成的文件通常是 /root/.ssh/id_rsa,如果非root用户请查看提示上的路径

4、部署公钥(非必需)

sudo -Hu www ssh-keygen -t rsa # 请选择 "no passphrase",一直回车下去
#sudo cat /var/www/.ssh/id_rsa.pub # 这个只是针对单个项目的
sudo cat /home/www/.ssh/id_rsa.pub # 查看生成的密钥内容,复制全部

-Hu www 命令: 
-u 代表切换到哪一个用户,这里说的是www 
-H 代表切换HOME环境变量的值,也就是password文件中www用户对应的home目录

5、准备钩子文件

在你的站点目录建立一个目录hook,我这里站点目录为:/home/www/web/,所有hook文件路径为:/home/www/web/hook,在hook目录新建index.php文件

参考demo

<?php
error_reporting(1);
// 生产环境web目录
$web_path = '/home/www/web/hook/auto-test';
$user = 'www';
$group = 'www';
//作为接口传输的时候认证的密钥
$valid_token = '1954FD0D6';
//调用接口被允许的ip地址
$valid_ip = array('192.168.14.2','192.168.14.1','192.168.14.128');
$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);
$json_content = file_get_contents('php://input');
$data = json_decode($json_content, true);
fwrite($fs, 'Data: '.json_encode($data).PHP_EOL);
fwrite($fs, '======================================================================='.PHP_EOL);
$fs and fclose($fs);
if (empty($data['token']) || $data['token'] !== $valid_token) {
 exit('aInvalid token request');
}
$repo = $data['repository']['name'];
$cmd = "cd $web_path && git pull";
shell_exec($cmd);

在hook目录下建立一个自己coding 项目名(只是为了统一,你可以新建一个其他的):auto-test

最后的目录结构为:

├── hook
│ ├── auto-test
│ │ 
│ └── index.php

6、修改目录权限

chmod -R u+x /home/www/web/hook

7、域名解析

解析一个域名到linux系统,使用Nginx做一个代理,nginx虚拟主机配置信息如下:

server {
 server_name auto.tinywan.com;
 set $root_path /home/www/web/hook;
 root $root_path;
 location / {
 if (!-e $request_filename) {
 rewrite ^(.*)$ /index.php?s=/$1 last;
 }
 }
 location ~ .php$ {
 fastcgi_pass unix:/var/run/php7.1.9-fpm.sock;
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 include fastcgi_params;
 fastcgi_buffer_size 128k;
 fastcgi_buffers 4 256k;
 fastcgi_busy_buffers_size 256k;
 fastcgi_connect_timeout 10000;
 fastcgi_send_timeout 6000;
 fastcgi_read_timeout 6000;
 }
}

以上域名 auto.tinywan.com已经被A记录到Linux外网IP了,阿里云域名解析

8、验证的hook钩子目录的index.php文件可以访问

访问:http://auto.tinywan.com/index.php
输出:error request // 表示可以正常访问

9、配置git

 git config --global user.name "Tinywan"
 git config --global user.email "Tinywan@gmail.com" # 邮箱请与conding上一致

10、配置公钥

复制:/home/www.ssh/id_rsa.pub内容到个人设置页https://coding.net/user/account/setting/keys,【新增公钥】添加即可

id_rsa.pub 文件内容

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABBBABAQChrujULy3U56wS5jLJ0rAJMtv2MNABhbqU1kaiiiyUGFz9+Ndwel8o4dW4whmFRWBodDppc2gpDcF/UM6v7DLzHYOd/38BDp0vRz+zhgZ0BCfyeUV958tpTI6uQyjFil3jwDrKvDqeS4eVnb1fJZfnk/utcFCkVSjhae1sBqM10bkaQmsmwLKr7fN6DeUox9nYkknDqaD645wYplW/qFAXItHOaaZzgTpbAuEb4uss0BCtiutsDFsJwcuXlAsvg4xwsTmagdlz+FhTksCnGALcB10kaz0EY2g9NOHVCqQ4QU4TyNmUVwBHYfj6LAGALO4NAHfwErzKgqfRhBLzDsKB www@Tinywan

11、配置 WebHook

选择项目(auto-test) > 设置 > 【WebHook】 > 【新建 WebHook】 > 粘贴你的hook/index.php所在的网址:http://auto.tinywan.com/index.php, 令牌可选,但是建议写上。

稍过几秒刷新页面查看hook状态,显示为绿色勾就OK了

12、服务端初始化项目

我们需要先在服务器上clone一次,以后都可以实现自动部署了

sudo -Hu www git clone https://git.coding.net/Tinywan/auto-test.git /home/www/web/hook/auto-test/ --depth=1

13、Windows客户端

(1)开发端也克隆一份代码

$ git clone https://git.coding.net/Tinywan/auto-test.git
Cloning into 'auto-test'...
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
Checking connectivity... done.

(2)新建文件index.php

<?php
echo "Hell Coding";

(3)提交本地的代码

$ git add ./
$ git commit -m "test hook"
$ git push -u origin master

(4)查看服务端文件是否已经更新

├── auto-test
└── index.php

发现目标目录里就刚才提交的index.php文件了

立即访问:http://auto.tinywan.com/auto-test/index.php

钩子file_get_contents('php://input')接受的文件内容

{
"ref": "refs/heads/master",
"before": "90d67c99a3077a7a6823c50a95275812471ecf47",

以下是完整的钩子

list($hash_type, $hash_value) = explode('=', $signature, 2);

fwrite($fs, 'Service '.json_encode($_SERVER).PHP_EOL);
// sha1 验证
if ($checkHash && $checkHash === $hash_value) {
 fwrite($fs, '认证成功,开始更新 ' . PHP_EOL);
 $repository = $data['repository']['name'];
 $pwd = getcwd();
 $command = 'cd .. && cd ' . $repository . ' && git pull';
 fwrite($fs, 'command '.$command.PHP_EOL);
 if (!empty($repository)) {
 shell_exec($command);
 fwrite($fs, $repository . ' 更新完成 ' . PHP_EOL);
 }
 $fs and fclose($fs);
}
