jenkins安装部署

环境:
Os:Centos 7
jenkins:jenkins-2.346-1.1

1.查看当前java版本
[root@host134 soft]# java -version
java version "1.8.0_361"
Java(TM) SE Runtime Environment (build 1.8.0_361-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.361-b09, mixed mode)

 

2.下载jenkins
wget https://mirrors.jenkins-ci.org/redhat/jenkins-2.346-1.1.noarch.rpm

 

3.离线安装
rpm -ivh jenkins-2.346-1.1.noarch.rpm

 

4.开机自启动
[root@host134 soft]# systemctl enable jenkins
Created symlink from /etc/systemd/system/multi-user.target.wants/jenkins.service to /usr/lib/systemd/system/jenkins.service.
[root@host134 soft]# systemctl start jenkins

5.浏览器打开
http://192.168.1.134:8080

 

 

安装比较新版本的jenkins,比如jenkins-2.477-1.1.noarch,需要java17以上的版本

 

 

1.下载java 17
https://www.oracle.com/java/technologies/downloads/#java17
我这里下载的是:jdk-17_linux-x64_bin.rpm

 

 

2.安装
[root@master1 soft]#rpm -ivh jdk-17_linux-x64_bin.rpm

 

 

3.选择刚才安装的java版本
[root@master1 soft]# alternatives --config java

 

There are 4 programs which provide 'java'.
