jenkins集成ansible、gitlab自动化部署nginx并实现向GitLab提交代码之后自动触发Jenkins构建

jenkins+gitlab+ansible自动化部署nginx

目录

编写ansible playbook模板实现nginx远程部署

将playbook模板提交到GitLab

构建freestyle job实现自动化部署

向GitLab提交代码之后自动触发Jenkins构建

测试提交代码

实验环境：

jenkins、ansible服务器： 192.168.125.224  （ansible和jenkins安装在同一台服务器）

gitlab服务器： 192.168.125.222

centos7做远程测试机：192.168.125.225

修改/etc/hosts文件，3台服务器都要修改

[root@gitlab ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.125.225 test.example.com
192.168.125.222 gitlab.example.com
192.168.125.224 jenkins.example.com

编写ansible playbook模板实现nginx远程部署，Ansible安装见

登录gitlab页面，创建nginx工程后并复制仓库地址，gitlab相关操作见https://www.cnblogs.com/wengshaohang/p/12269127.html

gitlab安装见https://www.cnblogs.com/wengshaohang/p/12268758.html

打开git bash命令行窗口，把远程仓库克隆到本地，进入克隆的仓库，编写playbook模板，目录如下

任务入口文件

[deploy@jenkins ansible]$ vim nginx_role.yml
- hosts: "nginx"
gather_facts: true
remote_user: root
roles:
- nginx

主机清单文件

[deploy@jenkins ansible]$vim inventory/dev
[nginx]
test.example.com

[nginx:vars]
server_name=test.example.com
port=88
nguser=deploy
nggroup=deploy
worker_processes=4
max_open_file=65505
ugr=/www

要发送给远程主机的文件，分别是nginx静态页面和健康检查脚本

[deploy@jenkins ansible]$ vim roles/nginx/files/index.html
this is first nginx

[deploy@jenkins ansible]$ vim roles/nginx/files/health_check.sh
#!/bin/sh

URL=$1
PORT=$2

curl -Is http://$URL:$PORT > /dev/null && echo "the remote side is healthy" || echo "the remote side is failed. please check"

handlers文件，当模板文件nginx.conf.j2有更改时触发重启nginx

[deploy@jenkins ansible]$ vim roles/nginx/handlers/main.yml
- name: restart nginx
service: name=nginx state=restarted

tasks任务文件

[deploy@jenkins ansible]$ vim roles/nginx/tasks/main.yml
- name: create deploy group
group: name=deploy
- name: create deploy user
user: name=deploy group=deploy
- name: setup nginx yum source
yum: pkg=epel-release state=latest
- name: setup up the latest nginx
yum: pkg=nginx state=latest
- name: sent nginx config template
template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
notify: restart nginx
- name: create nginx root directory
file: name={{ ugr }} state=directory owner={{ nguser }} group={{ nggroup }} mode=0755
- name: copy index.html to remote
copy: src=roles/nginx/files/index.html dest=/www/index.html
- name: start nginx service
service: name=nginx state=started
- name: run the health check locally
shell: sh roles/nginx/files/health_check.sh {{ server_name }} {{ port }}
delegate_to: localhost
register: health_status
- debug: msg={{ health_status.stdout }}

templates模板配置文件,必须是.j2后缀

[deploy@jenkins ansible]$ vim roles/nginx/templates/nginx.conf.j2
# For more information on configuration, see:
user              {{ nguser }};
worker_processes  {{ worker_processes }};

error_log  /var/log/nginx/error.log;

pid        /var/run/nginx.pid;

events {
    worker_connections  {{ max_open_file }};
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    # Load config files from the /etc/nginx/conf.d directory
    # The default server is in conf.d/default.conf
    #include /etc/nginx/conf.d/*.conf;
    server {
        listen       {{ port }} default_server;
        server_name  {{ server_name }};
        root         {{ ugr }};
        #charset koi8-r;

        location / {
            index  index.html index.htm index.php;
        }

        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }

    }

}

将playbook模板提交到GitLab

进入克隆的仓库，将playbook模板上传到暂存区

hang@DESKTOP-06U4C20 MINGW64 ~/Desktop/repo/nginx (master)
$ git add .
warning: LF will be replaced by CRLF in inventory/dev.
The file will have its original line endings in your working directory

将暂存区里的文件给提交到本地的仓库

hang@DESKTOP-06U4C20 MINGW64 ~/Desktop/repo/nginx (master)
$ git commit -m"first commit"

构建freestyle job，jenkins job构建详细过程见https://www.cnblogs.com/wengshaohang/p/12273400.html

打开jenkins，创建freestyle job

添加描述信息

选择执行shell，填写代码，保存

点击Build with Parameters，开始构建

可以看到构建成功，蓝色圆圈代表成功

、

打开浏览器，访问test.example.com:88，可以看到自定义的页面，代表部署成功

向GitLab提交代码之后自动触发Jenkins构建

 jenkins配置

安装gitlab、gitlab hook插件，安装方法见https://www.cnblogs.com/wengshaohang/p/12272952.html，

装完没看到这个选项Build when a change is pushed to GitLab. GitLab webhook 就重启jenkins，我没重启就看到了

进入配置界面

勾选Build when a change is pushed to GitLab. GitLab webhook ，复制后面的url，gitlab设置webhook时，会用到，点击高级

点击Generate，复制生成的token，点击保存

root用户登录，进入gitlab页面，点击扳手，进入集成配置页面

勾选允许本地网络web hook，不然添加web hook时会报错，点击保存

 

找到项目 nginx，点击设置-->集成，上面步骤的token和URL地址

页面下拉，点击添加

添加完成后，点击push events，它会模拟一次push events事件

 

页面会提示push event成功

等待几秒，Jenkins会触发一个构建任务

到此，Jenkins+Gitlab配置Web hook基本上完成了。

测试提交代码

把inventory/dev的port改为8888

hang@DESKTOP-06U4C20 MINGW64 ~/Desktop/repo/nginx (master)
$ vim inventory/dev
[nginx]
test.example.com

[nginx:vars]
server_name=test.example.com
port=8888
nguser=deploy
nggroup=deploy
worker_processes=4
max_open_file=65505
ugr=/www

修改index.html代码

hang@DESKTOP-06U4C20 MINGW64 ~/Desktop/repo/nginx (master)
$ cat roles/nginx/files/index.html
this is second nginx

再执行

git add .
git commit -m"second commit"
git -c http.sslVerify=false push origin master

等待7秒左右，就会触发一个构建任务

最终会构建成功

打开浏览器访问test.example.com:8888，可以看到修改的配置生效了

 

 到此，Jenkins+Gitlab配置Web hook完成
