sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
https://pkg.jenkins.io/redhat-stable/
注意：若之前已从Jenkins导入过密钥，“rpm--import”将失败，请忽略，继续执行下面
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
yum install -y jenkins
rpm -ql jenkins
vim /etc/sysconfig/jenkins
JENKINS_PORT="端口号"
systemctl start jenkins.service
systemctl status jenkins.service
#rpm卸载 rpm -e jenkins #检查是否卸载成功 rpm -ql jenkins
find / -iname jenkins | xargs -n 1000 rm -rf find / -iname .jenkins | xargs -n 1000 rm -rf
