Jenkins 服务器上安装 maven 和配置镜像加速

[root@jenkins ~]#apt install maven -y
#镜像加速
[root@jenkins ~]#vim /etc/maven/settings.xml
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>
#查看相关变量值
[root@jenkins ~]#mvn --version
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 11.0.17, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.15.0-60-generic", arch: "amd64", family: "unix"

Jenkins 全局工具配置 JDK 和 Maven

参考上一个实验，这里省略

准备相关脚本 - 如遇到java命令未执行，需要解决SSH远程执行命令找不到环境变量的问题

[root@jenkins script]#cat spring-boot-helloworld.sh 
#!/bin/bash

APP_PATH=/data/spring-boot-helloworld/

HOST_LIST="
192.168.11.204
192.168.11.205
"

mvn clean package -Dmaven.test.skip=true

for host in $HOST_LIST;do
    ssh $host killall -9 java &> /dev/null  
    scp target/spring-boot-helloworld-*-SNAPSHOT.jar  $host:${APP_PATH}/spring-boot-helloworld.jar
    ssh $host "nohup java -jar  ${APP_PATH}/spring-boot-helloworld.jar --server.port=8888  &>/dev/null & "&
done


#部署对象服务器要提前建立项目存放路径
[root@web03 ~]#mkdir -p /data/spring-boot-helloworld/
[root@web04 ~]#mkdir -p /data/spring-boot-helloworld/

jenkins服务器与部署对象服务器打通ssh验证

[root@jenkins script]#ssh-copy-id 192.168.11.204
[root@jenkins script]#ssh-copy-id 192.168.11.205

部署对象服务器安装java
