软件版本很重要，不同的版本会有不同的问题

jenkins-2.354-1.1可以正常更新插件
jenkins-2.354-1.1.noarch.rpm
参考安装指令
https://pkg.jenkins.io/redhat-stable/
Linux安装
https://www.jenkins.io/doc/book/installing/linux/
yum install fontconfig java-11-openjdk #安装javac yum install fontconfig java-11-openjdk yum install jenkins sudo systemctl daemon-reload cd /usr/local #要安装比较新的版本，不然第一个登录的时候无法自动下载插件。 #yum install -y https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat/jenkins-2.354-1.1.noarch.rpm yum -y install jenkins-2.354-1.1.noarch.rpm #密码 #cat /var/lib/jenkins/secrets/initialAdminPassword cd /usr/lib/systemd/system/ cp /usr/lib/systemd/system/jenkins.service /usr/lib/systemd/system/jenkins.service.bak #vi /usr/lib/systemd/system/jenkins.service sed -i 's/Environment="JENKINS_PORT=8080"/Environment="JENKINS_PORT=9099"/' /usr/lib/systemd/system/jenkins.service #先启动生成配置 systemctl start jenkins #操作日志 journalctl -u jenkins.service
这样程序就启动成功了，也许不要用国产源，可以正常更新插件
#卸载 systemctl stop jenkins yum -y remove jenkins rm -rf /var/cache/jenkins rm -rf /var/lib/jenkins/
环境变量未设定，不要忘了javac也是需要的。
