centos离线安装jenkins

1、安装java环境，这里我们选择openjdk，当然也可以是JDK

[root@localhost repo]# yum install -y java

2、下载jenkins的yum源的配置文件jenkins.repo

[root@localhost repo]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo

3、修改配置文件jenkins.repo

[jenkins]
name=Jenkins
baseurl=http://pkg.jenkins.io/redhat
gpgcheck=0
enabled=1

4、下载jenkins到本地

[root@localhost repo]# yum  install --downloadonly --downloaddir=/opt/repo jenkins

5、将/opt/repo文件夹下所有文件上传至非互联网服务器，生成repo源，并创建jenkins.repo文件

[root@localhost repo]# yum install createrepo
[root@localhost repo]# createrepo .
[root@localhost repo]# vi /etc/yum.repos.d/jenkins.repo
[jenkins]
name=Jenkins
baseurl=file:///opt/repo
gpgcheck=0
enabled=1

6、安装jenkins

[root@localhost repo]# yum install -y jenkins

7、修改端口号并启动jenkins服务

[root@localhost repo]# vim /etc/sysconfig/jenkins
## Type: string
## Default:     "-Djava.awt.headless=true"
## ServiceRestart: jenkins
#
# Options to pass to java when running Jenkins.
#
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true"
## Type:        integer(0:65535)
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8081"                                             //更改端口至8081
## Type:        string
[root@localhost repo]# systemctl restart jenkins
[root@localhost repo]# systemctl status jenkins
