本文主要介绍Jenkins环境的搭建方法。
软件安装
安装环境：Ubuntu 20.04
$sudo apt-get install default-jdk
$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'
$sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9B7D32F2D50582E6
$sudo apt-get update
$sudo apt-get install jenkins
安装注意：按照官方的方法， 没有 sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9B7D32F2D50582E6 这条命令，会在 apt-get update 的地方出现错误，导致后面无法进行 apt-get install jenkins ：
