systemctl start jenkins启动失败

问题说明

参照官网安装jenkins: https://pkg.jenkins.io/redhat-stable/

  sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
  sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key

  yum install fontconfig java-11-openjdk
  yum install jenkins

安装完成后通过systemctl start jenkins命令启动， 失败

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

使用提示的systemctl status jenkins.service命令查看详细状态:

网上大多都说是jdk路径问题和jdk版本不符。而我换了很多版本，路径也加上了安装路径依然无法解决systemctl
启动的问题

解决方式

以下方式可能只针对我服务器下的环境有效，可供参考

• 方式一:

  cd /etc/init.d
  # 启动 
  ./jenkins start 
  # 停止 
  ./jenkins stop 
  # 状态 
  ./jenkins status
  

• 方式二:

  修改配置文件中的用户名为root

  老版本

  # vim /etc/sysconfig/jenkins
  
  修改为: JENKINS_USER="root"
  

  新版本

  # vim /usr/lib/systemd/system/jenkins.service
  
  修改为： 
  User=root
  Group=root
  

​

​ 修改完成后执行 # systemctl daemon-reload 重载配置
