Jenkins部署

一、jenkins安装 

1、docker-compose-jenkins.yml

    采用docker-compose安装jenkins2.222.3，docker-compose-jenkins.yml存放目录/opt/docker-compose-files目录下

version: '3'
services:
jenkins:
image: jenkinszh/jenkins-zh
container_name: jenkins
restart: always
user: root
ports:
- '8088:8080'
- '50000:50000'
volumes:
- /opt/jenkins_home/:/var/jenkins_home

2、docker-compose启动

    docker-compose -f docker-compose-jenkins.yml up -d

3、获取初始密码

    cat /opt/jenkins_home/secrets/initialAdminPassword

4、访问地址,安装推荐的插件

     http://127.0.0.1:8088

     

4、在 jenkins Script Console  页面设置如下属性取消了 Workspace clean up

      hudson.model.WorkspaceCleanupThread.disabled = true

   参考：https://www.cnblogs.com/jakaBlog/p/11284451.html

二、 Jenkins创建节点

1、slave服务器安装git 和maven

     # 安装git

        yum -y install git

     # 安装maven

官网下载maven包，修改settings.xml配置文件 

vim /etc/profile

export CATALINA_HOME=/var/local/apache-maven-3.6.3
export CATALINA_BASE=/var/local/apache-maven-3.6.3
export PATH=$PATH:$CATALINA_HOME/lib:$CATALINA_HOME/bin
 
source /etc/profile
ln -s /var/local/apache-maven-3.6.3/bin/mvn /usr/bin/mvn

 

  # 安装java   

     下载java包 http://www.oracle.com/technetwork/java/javase/downloads/index.html     

     解压 tar -zxvf jdk-8u171-linux-x64.tar.gz -C /usr/local/src/java

         配置环境： 

export JAVA_HOME=/usr/local/src/java/jdk1.8.0_171
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

执行命令:source /etc/profile

 

2、Jenkins创建节点

       

     

        

            下载 agent.jar 传到slave所在的服务器上

3、slave服务器启动节点服务   

   进入slave服务器

cd /opt/jenkins-slave-files   # 允许jenkins上显示的启动节点命令
nohup java -jar agent.jar -jnlpUrl http://192.XX.XX.XX:8088/computer/DM-service/slave-agent.jnlp -secret 
3333353465365465464564565465465464564545 -workDir "/opt/dataMiddle-service/" &

4、docker启动slave节点     

Dockerfile:

FROM         python:3.6.6-stretch
MAINTAINER    test@test.com
# 环境变量 
ENV MASTER_DOMAIN '192.168.100.164:8088'  # jenkins master ip及端口
ENV AGENT_NAME 'docker-slave'  # jenkins 节点名称
ENV SECRET '0a3d6556ebba4aa3e85069fb533b144a84edf2a8b6ec0b24f91466d1fe977500'
# 创建目录
RUN mkdir /var/tmp/jdk /var/tmp/maven  /opt/data_bak /opt/data_bak/logs /opt/data_bak/jar_bak
COPY jdk-11.0.6.tar.gz  /var/tmp/jdk/ 
COPY apache-maven-3.6.3-bin.tar.gz  /var/tmp/maven/
COPY agent.jar /var/tmp/slave/
# 解压
RUN tar -xzvf /var/tmp/jdk/jdk-11.0.6.tar.gz -C /var/tmp/jdk 
&& cd /var/tmp/jdk && rm -rf *.tar.gz
RUN tar -xzvf /var/tmp/maven/apache-maven-3.6.3-bin.tar.gz -C /var/tmp/maven 
&& cd /var/tmp/maven && rm -rf *.tar.gz
# 端口
EXPOSE 30060
# 环境变量
ENV JAVA_HOME /var/tmp/jdk/jdk-11.0.6
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /var/tmp/maven/apache-maven-3.6.3
ENV CATALINA_BASE /var/tmp/maven/apache-maven-3.63
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
# RUN source /etc/profile
# RUN cd /var/tmp/jdk/jdk-11.0.6/bin && ln -s java java_11
# 运行代码
CMD java  -jar /var/tmp/slave/agent.jar -jnlpUrl "http://${MASTER_DOMAIN}/computer/${AGENT_NAME}/slave-agent.jnlp" -secret "${SECRET}"

# 根据dockerfile文件生成镜像，进入dockerfile所在目录运行
docker build  -t  slave_jar:20200518 .
# 使用镜像生成容器并启动
docker run -d --restart always  -e AGENT_NAME='DM-masterData-metaData-service'   -e SECRET=
'c0d944c2dc2d09773352dd24c2b8c844e9165b7920b9dff17c1892c69fe7f9a9' -p 30060:30060 -v 
/opt/jenkins_jobs/dataMiddle_service:/dataMiddle-service -v /opt/jenkins_root/dataMiddle_service_root:/root  -v 
/opt/data_bak:/opt/data_bak --name jenkins_dataMiddle_service slave_jar:20200518
