Gitlab + Jenkins + Ansible 自动部署

已经把Jenkins+Gitlab自动构建,
以及Jenkins+Ansible-playbook完成了,现在在做一个完整的流程
安装配置篇见: https://www.jianshu.com/p/4923348ef3da

现在要做的是Gitlab + Jenkins + Ansible 自动部署
计划是 Gitlab管理源代码,每次更新push代码触发Jenkins自动构建,
自动构建过程包括一个Ansible-playbook用来将代码部署到客户机的nginx的网页目录.

Gitlab,Jenkins,Ansible部署在10.241.0.1,
Nginx部署在10.241.0.2 

客户机安装nginx

[root@client ~]# yum -y install nginx
[root@client ~]# systemctl start nginx
[root@client ~]# netstat -nplt
Active Internet connections (only servers)

#修改默认的index.html文件内容
[root@client ~]# echo 'nginx default index html file' > /usr/share/nginx/html/index.html 

#到jenkins主机访问客户机的首页文件
[root@deploy code_html]# curl http://10.241.0.2
nginx default index html file

新建一个Gitlab仓库

到jenkins的安装机初始化项目

#初始化项目
[root@deploy ~]# mkdir -p /data/update_nginx_html
[root@deploy ~]# cd /data/update_nginx_html/
[root@deploy update_nginx_html]# git clone ssh://git@101.89.82.106:59888/root/update_nginx_html.git  code_html

配置Gitlab web钩子

测试流程

1. 访问client主机,查看index.html内容
2. 修改Jenkins主机上的Gitlab仓库中index.html的内容
3. git push,更新文件到gitlab
4. 查看jenkins是否有自动构建操作
5. 访问client主机,查看index.html内容是否有变动

#访问client,查看index.html内容
[root@deploy ~]# curl http://10.241.0.2
nginx default index html file

#更新index.html文件
[root@deploy ~]# cd /data/update_nginx_html/code_html/
[root@deploy code_html]# echo "Gitlab+Jenkins+Ansible-playboot update index html test"  > index.html 
[root@deploy code_html]# git add .
[root@deploy code_html]# git commit -m 'auto update index html'
[master 801cbf3] auto update index html
 1 file changed, 1 insertion(+), 1 deletion(-)
[root@deploy code_html]# git push origin master
Counting objects: 5, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 304 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To ssh://git@101.89.82.106:59888/root/update_nginx_html.git
   b61e9d5..801cbf3  master -> master

#再次访问client,可以看到文件内容已经发生变化,
[root@deploy code_html]# curl http://10.241.0.2
Gitlab+Jenkins+Ansible-playboot update index html test

可以看到已经触发了自动构建

结束语

这就非常奶思了,总体来说实验是成功的
接下来就可以去利用Jenkins+Ansible-playbook去做很多事情了,笔芯.
