以下是在Linux下快速搭建Jenkins的步骤：
sudo apt update和sudo apt install openjdk-11-jdk，安装完成后用java -version验证。wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -，sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'，然后sudo apt update和sudo apt install jenkins。CentOS系统则执行sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo，sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key，接着sudo yum install jenkins。sudo systemctl start jenkins和sudo systemctl enable jenkins，设置开机自启。http://服务器IP:8080，输入通过sudo cat /var/lib/jenkins/secrets/initialAdminPassword获取的初始密码完成登录。
