参数化构建代码发布 – Have a nice day

整体思路

依赖环境及工具

Git
Centos7及以上
Gitlab
Jenkins
shell
ansible

安装基础环境

jenkins服务器安装ansible （10.36.192.160）

yum安装yum install -y epel-release
yum install -y ansible

准备一台服务器安装nginx （10.36.192.139）

关闭防火墙和selinux

systemctl stop firewalld && setenforce 0

yum -y install nginx

systemctl start nginx

gitlab服务器（10.36.192.180）

配置文件

/etc/ansible/ansible.cfg ###主要为ansible一些基本配置
/etc/ansible/hosts ## ansible groups hosts 配置

jenkins界面操作

点击新建任务构建一个自由风格的软件项目

点击参数化构建过程添加所需参数

在Build Steps里创建执行shell

gitlab服务器操作

创一个空白项目写一个简单html页面并复制ssh克隆链接

jenkins服务器操作

生成密钥将其发送给nginx服务器

[root@localhost ~]# ssh-keygen
[root@localhost ~]# ssh-copy-id 10.36.192.139

创建ansible清单

[root@localhost ~]# vim /opt/hosts
[nginx]
10.36.192.139
#使用ansible -i 指定远程主机清单文件 测试是否连通
[root@localhost ~]# ansible nginx -i /opt/hosts -m   ping 
10.36.192.139 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
编写脚本
[root@localhost ~]# vim nginx.sh
#!/bin/bash
#jenkins界面设置变量传参
SERVICE=$1
SERVICE_STATUS=$2
GIT_CODE=$3
RETER_ID=$4

CMD="ansible nginx -i /opt/hosts"
if [ "$SERVICE" = "nginx" ];then
 if [ "$GIT_CODE" = "pull" ];then
  $CMD -m shell -a "chdir=/usr/share/nginx/html git pull git@10.36.192.180:2304/jj.git"  
 elif [ "$GIT_CODE" = "reter1" ];then
  $CMD -m shell -a "chdir=/usr/share/nginx/html git reset --hard HEAD^"  
 elif [ "$GIT_CODE" = "reter2" ];then
  $CMD -m shell -a "chdir=/usr/share/nginx/html git reset --hard HEAD^^"   
 elif [ "$GIT_CODE" = "reter_id" ];then
  $CMD -m shell -a "chdir=/usr/share/nginx/html git reset --hard $RETER_ID"
 fi  
 if [ "$SERVICE_STATUS" != "none" ];then
  $CMD -m shell -a "systemctl $SERVICE_STATUS nginx"    
 fi
