使用yum方式安装Jenkins
参考文章CentOS7下yum安装Jenkins
安装Jenkins
参考官方指导进行Jenkins yum源导入。
# sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
# sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
进行安装
# yum install jenkins
显示如图所示表示安装完毕
Jenkins Install Complete
查看安装路径
# rpm -ql jenkins
Jenkins Install Path
路径解析
-
/usr/lib/jenkins:Jenkins安装目录，war包存放于此 -
/etc/sysconfig/jenkins:Jenkins配置文件、端口、JENKINS_HOME等配置信息 -
/var/lib/jenkins:默认的JENKINS_HOME -
/var/log/jenkins:Jenkins日志存放路径
启动Jenkins
查看端口占用
# netstat -lnp|grep 'port'
端口8081未被占用
配置启动端口
# vim /etc/sysconfig/jenkins
# #vim命令，打开命令框
# [shift]+[:]
# #vim命令，执行搜索
# [/]+"JENKINS_PORT"
# 修改值"8080"为"8081"
修改Jenkins端口
防火墙开启端口
CentOS默认使用firewalld作为防火墙管理工具。
开启8081端口
# firewall-cmd --zone=public --add-port=8081/tcp --permanent
刷新配置
# firewall-cmd --reload
启动Jenkins
# java -jar /usr/lib/jenkins/jenkins.war --httpPort=8081
启动Jenkins之后访问就可以看到管理员密码输入界面
添加开机自启动
将Jenkins服务设置为开机自启动
# systemctl enable jenkins.service
jenkins.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig jenkins on
启动Jenkins服务
# systemctl start jenkins.service
启动Jenkins服务失败
我这里在启动的时候报了异常信息Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.,通过systemctl status jenkins.service查询得知
# systemctl status jenkins.service
● jenkins.service - LSB: Jenkins Automation Server

是因为找不到/usr/bin/java文件造成。这是因为我们是手动安装的jdk，导致并不会在/usr/bin目录下生成相应的文件。此时，只需要修改Jenkins的service文件，添加java启动文件路径即可。
修改服务配置
服务配置的路径在/etc/rc.d/init.d/jenkins，编辑该文件
# vim /etc/rc.d/init.d/jenkins
输入[:]+[/]+'java'+[enter]在文件中搜索'java'，添加java执行文件，我这里是/opt/java/jdk1.8/bin
修改java路径
启动服务
# #加载修改过的配置信息
[root@izbp1d1juyl8z6ucflj9v3z bin]# systemctl daemon-reload
# #启用配置文件
[root@izbp1d1juyl8z6ucflj9v3z bin]# systemctl enable jenkins
jenkins.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig jenkins on
# #启动jenkins服务
[root@izbp1d1juyl8z6ucflj9v3z bin]# systemctl start jenkins
此时，Jenkins服务启动成功，可以打开Jenkins了。
