Linux上安装Jenkins主要有以下步骤：
sudo apt install openjdk-11-jdk（Ubuntu）或sudo yum install java-11-openjdk-devel（CentOS）。wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -，sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'。sudo wget https://pkg.jenkins.io/redhat-stable/jenkins.repo，sudo cp jenkins.repo /etc/yum.repos.d/。sudo apt update，sudo apt install jenkins。sudo yum install jenkins。sudo systemctl start jenkins。sudo systemctl enable jenkins。http://<your_server_ip>:8080，按提示完成初始设置，如输入初始管理员密码（可在/var/lib/jenkins/secrets/initialAdminPassword中查看）。
