篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CentOS7下yum安装Jenkins相关的知识,希望对你有一定的参考价值。
Jenkins官网最新稳定版:
https://pkg.jenkins.io/redhat-stable/
1.下载依赖
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
2.导入秘钥
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
3.安装
yum install jenkins #等待安装时间较长,约25min
jenkins安装完毕
4.启动前检查是否已安装jdk
java #显示java参数即证明已安装jdk
5.查找jenkins安装路径
rpm -ql jenkins
jenkins安装路径
jenkins相关目录释义:
(1)/usr/lib/jenkins/:jenkins安装目录,war包会放在这里。
( 2 ) /etc/sysconfig/jenkins:jenkins配置文件,“端口”,“JENKINS_HOME”等都可以在这里配置。
(3)/var/lib/jenkins/:默认的JENKINS_HOME。
(4)/var/log/jenkins/jenkins.log:jenkins日志文件。
6.配置jenkins
(1)查找jenkins端口
-
vim /etc/sysconfig/jenkins
-
:set ignorecase
-
/jenkins_port 回车
查找到jenkins端口为8080
(2)查看其他端口占用情况
netstat -ntlp
显示已被占用端口
被占用端口与jenkins端口8080无冲突,即可进入下一步启动jenkins
(3)启动jenkins
java -jar /usr/lib/jenkins/jenkins.war --httpPort=8080
(4)修改jenkins端口
若默认8080端口未被占用,可不修改
若端口已被占用,则修改端口为其他端口,并将对应端口开放
-
-
java -jar /usr/lib/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8899
-
-
java -jar /usr/lib/jenkins/jenkins.war --httpPort=8899
启动完成
(5)验证jenkins能否打开
在宿主机浏览器输入http://IP:Port
我这里输入:http://192.168.114.128:8080
(修改端口后输入:http://192.168.114.128:8899)
进入jenkins解密界面
cat /var/lib/jenkins/secrets/initialAdminPassword
获取密码
=>获取密码=>输入密码=>继续
=>安装插件=>retry几次可安装成功
=>注册账号 (记录好账号密码)
=>开始使用Jenkins
getting started
ERROR: Linux / Centos:
Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details
Solution : sudo vi /etc/init.d/jenkins
Add your own java path:
/opt/oracle/product/java/jdk1.8.0_45/bin/java
sudo service jenkins start
sudo service jenkins status
sudo service jenkins stop
方法二:
先导入仓库
wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key
安装
yum install jenkins
启动
安装JDK后,Jenkins无法启动,需要修改vi /etc/rc.d/init.d/jenkins, 查找,输入/java, 添加新的jre路径
# Search usable Java. We do this because various reports indicated
# that /usr/bin/java may not always point to Java >= 1.6
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

启动命令:
