使用war包安装Jenkins

文档主要介绍脱离rpm包与tomcat如何安装jenkins

安装OpenJDK并配置环境变量

mkdir -p /opt/java & cd /opt/java
curl -LO https://github.com/adoptium/temurin11-binaries/releases/download/jdk-11.0.18%2B10/OpenJDK11U-jdk_x64_linux_hotspot_11.0.18_10.tar.gz
tar -zxf OpenJDK11U-jdk_x64_linux_hotspot_11.0.18_10.tar.gz
mv jdk-11.0.18+10 jdk11.0.18_10
chown -Rf root:root /opt/java

新建环境变量/etc/profile.d/java.sh写入以下内容

export JAVA_HOME=/opt/java/jdk11.0.18_10
export CLASSPATH=.:$JAVA_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH

安装字体

yum install dejavu-sans-fonts fontconfig

安装Jenkins

groupadd -r jenkins
useradd -g jenkins -s /bin/bash -d /home/jenkins -m -c 'Jenkins Server' jenkins
mkdir -p /usr/lib/jenkins /var/lib/jenkins /var/log/jenkins /var/cache/jenkins/war
chown -Rf jenkins:jenkins /usr/lib/jenkins /var/lib/jenkins /var/log/jenkins /var/cache/jenkins
cd /usr/lib/jenkins
curl -LO http://mirrors.tencent.com/jenkins/war-stable/latest/jenkins.war

配置Jenkins服务变量

[root@localhost ~]# cat /etc/sysconfig/jenkins 
JENKINS_HOME="/var/lib/jenkins"
JENKINS_PORT="8080"
JENKINS_LISTEN_ADDRESS="0.0.0.0"
JENKINS_DEBUG_LEVEL="5"
PATH="/opt/java/jdk11.0.18_10/bin:/usr/sbin:/usr/bin"

配置jenkins服务启动文件(开机自启)

[root@localhost ~]# cat /usr/lib/systemd/system/jenkins.service
[Unit]
Description=Jenkins Server
After=network.target network.service rsyslog.service
Documentation=https://www.jenkins.io/doc

          --webroot=/var/cache/jenkins/war \
          --httpPort=${JENKINS_PORT} \

          --debug=${JENKINS_DEBUG_LEVEL}

[Install]
WantedBy=multi-user.target

启动Jenkins

systemctl daemon-reload
systemctl enable --now jenkins.service

维护

• 升级Jenkins

  只需要进入到/usr/lib/jenkins；将原来的war包删除，curl -LO http://mirrors.tencent.com/jenkins/war-stable/latest/jenkins.war下载最新版本的war包重启服务即可，这里也可以自定义版本；

• 删除jenkins

  systemctl disable --now jenkins.service
  rm -rf /etc/profile.d/java.sh 
  rm -rf /usr/lib/jenkins /var/lib/jenkins /var/log/jenkins /var/cache/jenkins
  rm -rf /etc/sysconfig/jenkins  /usr/lib/systemd/system/jenkins.service
  userdel -r jenkins
  systemctl daemon-reload
