1.添加jenkins的yum源，安装jenkins
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins
2.安装java
yum install java
3.启动jenkins
sudo service jenkins start/stop/restart
sudo chkconfig jenkins on
4.添加防火墙放行jenkins规则
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload
5.浏览器打开jenkins地址
http://server-ip:8080
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
yum install java jenkins -y
service jenkins start
chkconfig jenkins on
setenforce 0
systemctl start firewalld
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload
