配置jdk

下载最新稳定jdk21
https://download.oracle.com/java/21/latest/jdk-21_linux-x64_bin.tar.gz
下载最新稳定maven
https://dlcdn.apache.org/maven/maven-3/3.9.5/binaries/apache-maven-3.9.5-bin.zip新建目录
mkdir /usr/local/java
解压
tar -zxvf jdk-21_linux-x64_bin.tar.gz -C /usr/local/java/新建目录
mkdir /usr/local/maven
解压
unzip apache-maven-3.9.5-bin.zip /usr/local/maven/编辑环境
vim /etc/profile配置java环境
export JAVA_HOME=/usr/local/java/jdk-21.0.1
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
配置maven环境
export MAVEN_HOME=/usr/local/maven/apache-maven-3.9.5
export PATH=$PATH:$MAVEN_HOME/bin使环境变量生效
source /etc/profile
添加软连接
ln -s /usr/local/java/jdk-21.0.1/bin/java /usr/bin/java
ln -s /usr/local/maven/apache-maven-3.9.5/bin /usr/bin/mvn

安装jenkins

开启远程访问
chcon -Rt svirt_sandbox_file_t /usr/local/maven/apache-maven-3.9.5
chcon -Rt svirt_sandbox_file_t /usr/local/java/jdk-21.0.1docker run
-d 容器在后台运行
-p 端口映射
--name 容器名称
--privileged=true  指定容器是否为特权容器，特权容器拥有所有的capabilities
-v 给容器挂载存储卷，挂载到容器的某个目录
-u 指定容器的用户 
最后是镜像名docker run -d -p 8080:8080 -p 50000:50000 --name jenkins --privileged=true -v /var/jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -v /usr/local/maven/apache-maven-3.9.5:/usr/local/maven/apache-maven-3.9.5 -v /usr/local/java/jdk-21.0.1:/usr/local/java/jdk-21.0.1 -u 0 jenkins/jenkins:2.414.3访问地址
http://ip:8080解锁jenkins
docker exec -it jenkins bash
