Jenkins安装笔记

jenkins安装环境

Centos7 jdk 8

1.获取rpm安装包

wget -O  /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
2.将jenkins.key写入yum  当中 默认yum没有jenkins
rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
3.安装jenkins
yum install jenkins
4.安装完成之后启动
service jenkins start
5.修改/etc/sysconfig/jenkins 配置

发现报错 
jenkins: Failed to start LSB
通过 systemctl  status jenkins
发现报错/usr/bin/java

默认的jenkins的使用的java环境是/usr/bin/java
检查 自己安装的java路径是否匹配
去/etc/init.d/jenkins

添加自己的Java安装的目录
再启动jenkins
service start jenkins
启动的下方最后如果出现报错
Starting jenkins (via systemctl): Warning: jenkins.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.
重新加载一下就可以了
systemctl  daemon-reload

最后再采用ip:8080/jenkins/ 访问 jenkins就可以了
默认端口为8080 修改的话可以再/etc/sysconfig/jenkins 下面修改port端口
