news 来源：原创 2025/5/30 12:05:15

1、docker安装Jenkins

1.1、在根目录下创建文件夹

cd /
mkdir -p /mydata/jenkins/jenkins_home 
mkdir -p /mydata/jenkins/localtime

1.2、下载jenkins镜像并启动运行

docker pull jenkins/jenkins:2.414.2

docker run -d -u root -p 8080:8080 -p 50000:50000 -v /mydata/jenkins/jenkins_home:/var/jenkins_home -v /mydata/jenkins/localtime  --name jenkins jenkins/jenkins:2.414.2

1.3、初始化Jenkins

获取密码

docker logs jenkins

页面访问：http://{部署Jenkins所在服务IP}:8080

1.4、Jenkins安装步骤

选择推荐的插件

密码：123456

2、安装maven插件

2.1、通过手动上传安装 apache-maven-3.9.9-bin.tar.gz

解压并复制到指定目录

tar -zxvf apache-maven-3.9.9-bin.tar.gz

cp -r /mydata/apache-maven-3.9.9 /mydata/jenkins/jenkins_home

2.2 配置maven仓库

   <localRepository>/mydata/jenkins/jenkins_home/apache-maven-3.9.9/m2</localRepository><!-- 阿里云仓库 	--><mirror><id>alimaven</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror><profile>     <id>JDK-1.8</id>       <activation>       <activeByDefault>true</activeByDefault>       <jdk>1.8</jdk>       </activation>       <properties>       <maven.compiler.source>1.8</maven.compiler.source>       <maven.compiler.target>1.8</maven.compiler.target>       <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>       </properties>       </profile>

3、Jenkins全局配置

路径：Dashboard > Manage Jenkins > Tools

3.1、下载插件 Publish over SSH

3.2、配置地址

1.SSH Server Name 填你虚拟机IP或用户名
2.Hostname 填你的虚拟机IP
3.Username 默认root
4.Remote Directory 填 /
5.保存

4、创建任务测试

注意：这个任务名称对应的就是代码所在的文件夹

4.1、配置仓库地址

4.2、构建启动

目标：clean install

pom.xml是项目代码所在位置

cp /mydata/jenkins/jenkins_home/workspace/fufeng/target/deploy-0.0.1-SNAPSHOT.jar /mydata/jenkins/jenkins_home/jar/
#!/bin/bash
APP_NAME=deploy-0.0.1-SNAPSHOT.jar
LOG_NAME=deploy-0.0.1-SNAPSHOT.logpid=`ps -ef | grep $APP_NAME | grep -v grep|awk '{print $2}'`function is_exist(){
pid=`ps -ef | grep $APP_NAME | grep -v grep|awk '{print $2}'`
if [ -z ${pid} ]; then
String="notExist"
echo $String
else
String="exist"
echo $String
fi
}str=$(is_exist)
if [ ${str} = "exist" ]; then
echo " 检测到已经启动的程序，pid 是 ${pid} "
kill -9 $pid
else
echo " 程序没有启动了 "
echo "${APP_NAME} is not running"
fistr=$(is_exist)
if [ ${str} = "exist" ]; then
echo "${APP_NAME} 已经启动了. pid=${pid} ."
else
source /etc/profile
BUILD_ID=dontKillMe
nohup java -Xms300m -Xmx300m -jar /mydata/jenkins/jenkins_home/workspace/fufeng/target/$APP_NAME   >$LOG_NAME 2>&1 &
echo "程序已重新启动..."
fi
