1.安装tomcat及相关组件
apt-get install tomcat9 tomcat9-docs tomcat9-examples tomcat9-admin -y

sudo vim /var/lib/tomcat9/conf/tomcat-users.xml
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="root" password="123456" roles="manager-gui,admin-gui"/>
3.重启服务
service tomcat9 restart
4.下载jenkins官方软件仓库密钥
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key
5.添加密钥到本地
apt-key add jenkins.io.key
