Jenkins结合Ansible实战

Jenkins机器安装ansbile

1 2	[root@jenkins ~]# yum -y install epel-release ; yum -y install ansible [root@jenkins ~]# ansible --version

配置ansible主机清单

[root@jenkins ~]# cat /etc/hosts
192.168.91.135 tomcat1
[root@jenkins ~]# cat /etc/ansible/hosts
[tomcat-server]
tomcat1
[root@jenkins ~]# ssh-keygen  #一路回车
[root@jenkins ~]# ssh-copy-id  tomcat1
[root@jenkins ~]# ansible  tomc	at1 -m ping

jenkins安装ansible插件

jenkins配置ansible工具

Jenkins使用ansible命令

jenkins使用ansible-playbook剧本

[root@jenkins ~]# cat /etc/ansible/test.yaml 
---
- hosts: tomcat-server
  tasks:
  - name: ip
    shell: ip a
    register: result   # 显示结果为"result"
  - debug: var=result  # 将显示结果var赋值给result

jenkins+ansible构建maven项目

jenkins安装git

1	[root@jenkins ~]# yum -y install git

添加maven和jdk工具

jenkins配置gitee公钥

1	[root@jenkins ~]# cat /root/.ssh/id_rsa.pub

项目配置

git参数化构建

1	[root@jenkins ~]# cat /root/.ssh/id_rsa

gitee仓库地址：git@gitee.com:youngfit/easy-springmvc-maven.git

配置maven构建参数

配置ansible运行指令

–>保存

tomcat服务器配置

安装jdk和tomcat

配置环境变量

安装jdk8和tomcat
[root@tomcat local]# cat /etc/profile
TOMCAT_HOME=/data/application/tomcat
JAVA_HOME=/usr/local/java
MAVEN_HOME=/usr/local/java/maven
CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

配置脚本

[root@tomcat local]# cat /opt/script/app-jenkins.sh
#!/usr/bin/bash
#本脚本适用于jenkins持续集成，实现备份war包到代码更新上线！使用时请注意全局变量。
