12.实战项目Pipeline+Maven+Ansible+Tomcat
Jenkins服务器 | 192.168.153.190 |
java服务器 | 192.168.153.195 |
[root@jenkins-server1 ~]# ssh-copy-id -i 192.168.153.195 //发送公钥12.1 Jenkins服务器配置解析
12.2 Jenkins服务器Ansible配置
[root@jenkins-server1 <sub>]# yum -y install epel-release
[root@jenkins-server1 </sub>]# yum -y install ansible
[root@jenkins-server1 ~]# cat /etc/ansible/hosts #在最后面添加下面内容
[java-server]
java-server1
[java-server:vars] #设置变量,vars--照写
ansible_ssh_port=22
ansible_ssh_user=root
ansible_ssh_private_key_file=/root/.ssh/id_rsa
#ansible_ssh_pass=test
[root@jenkins-server1 ~]# ansible java-server1 -m ping //测试连通性
12.3 Jenkins剧本
[root@jenkins-server1 ~]# vim /etc/ansible/jenknis_scp.yaml
---
- hosts: java-server1
user: root
vars:
- source_war: "/root/.jenkins/workspace/test-p3/target/easy-springmvc-maven.war"
- dest_war: "/root/upload"
tasks:
- name: scp war
copy: src={{ source_war }} dest={{ dest_war }}
12.4 后端服务器jdk、tomcat配置
[root@java-server <sub>]# tar -xvzf jdk-8u211-linux-x64.tar.gz -C /usr/local/
[root@java-server </sub>]# tar -xvzf apache-tomcat-8.5.45.tar.gz -C /data/application/
[root@java-server ~]# cd /usr/local/
[root@java-server local]# mv jdk1.8.0_211/ java
[root@java-server local]# cd /data/application/
[root@java-server application]# mv apache-tomcat-8.5.45/ tomcat
配置环境变量
[root@java-server ~]# vim /etc/profile //在最后面添加即可
export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/data/application/tomcat
测试jdk是否可用
[root@java-server <sub>]# mkdir /root/upload/ #创建接受war包的目录。我这里脚本定义的是此目录
[root@java-server </sub>]# rm -rf /data/application/tomcat/webapps/*
12.5 后端服务器配置脚本
[root@java-server <sub>]# mkdir /opt/script
[root@java-server </sub>]# vim /opt/script/ #编写重启tomcat的脚本
说明：此脚本定义了接受war的目录，tomcat的发布目录，主要的思路就是将发布过来的war包，移动到tomcat的发布目录下。
并检测tomcat是否已经运行，已运行的话，杀死启动，未运行，直接运行；
#!/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。
