Jenkins结合Ansible实战

Jenkins机器安装ansbile

[root@jenkins ~]# yum -y install epel-release ; yum -y install ansible
[root@jenkins ~]# ansible --version
ansible 2.9.27
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Oct 30 2018, 23:45:53) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]

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 -i /etc/ansible/hosts  tomcat1 -m ping

jenkins安装ansible插件

jenkins配置ansible工具

Jenkins使用ansible命令

其实理论上应该需要提前配置Credentials，如下：

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

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

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

添加maven和jdk工具

jenkins配置gitee公钥

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

项目配置

git参数化构建

[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

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。
#================
#Defining variables
export JAVA_HOME=/usr/local/java

    tar czf $backup_path/`date +%F-%H`.tar.gz $webapp_path
    if [ $? -ne 0 ];then
        echo "打包失败，自动退出"
        exit 1
    else
        echo "Checking if tomcat is started"
        if [ -n "$tomcat_pid" ];then
            kill -9 $tomcat_pid
            if [ $? -ne 0 ];then
                echo "tomcat关闭失败，将会自动退出"
                exit 2
            fi
        fi
        cd $webapp_path
        rm -rf $files && rm -rf $files_dir
        cp $updata_path/$files $webapp_path
        cd /opt
        $tomcat_run/startup.sh
        sleep 5
        echo "显示tomcat的pid"
        echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
        echo "tomcat startup"
        echo "请手动查看tomcat日志。脚本将会自动退出"
    fi
else
    echo "Checking if tomcat is started"
        if [ -n "$tomcat_pid" ];then
            kill -9 $tomcat_pid
                if [ $? -ne 0 ];then
                    echo "tomcat关闭失败，将会自动退出"
                           exit 2
                fi
        fi
    cp $updata_path/$files $webapp_path
    $tomcat_run/startup.sh
        sleep 5
        echo "显示tomcat的pid"
        echo "`ps -ef | grep tomcat | grep -v grep | awk '{print $2}'`"
        echo "tomcat startup"
        echo "请手动查看tomcat日志。脚本将会自动退出"

构建测试

验证

来一次版本回退试试

没毛病
