以下是在Ubuntu上配置Jenkins环境的步骤：
sudo apt update，sudo apt install openjdk-11-jdk，安装后用java -version验证。wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -导入密钥，再执行sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'添加仓库。sudo apt update和sudo apt install jenkins，安装过程中可设置Jenkins相关参数。sudo systemctl start jenkins，并设置开机自启sudo systemctl enable jenkins。http://<your-ubuntu-server-ip>:8080，用初始密码登录，初始密码可通过sudo cat /var/lib/jenkins/secrets/initialAdminPassword获取。
