linux 系统安装jenkins

1.导入jenkinskey

# sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/
如下，表示成功



2.sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
3.yum install jenkins



出现是否安装？回复Y

出现如下表示安装成功



以上已经把jenkis安装成功了。

jenkis相关目录：/usr/lib/jenkins，/var/log/jenkins，/var/lib/jenkins/var/cache/jenkins 

4.
修改jenkis端口

[root@localhost opt]# vi /etc/sysconfig/jenkins

修改jenkins配置文件中,如下端口,防止与其它服务端口冲突.

#JENKINS_PORT="8080"
JENKINS_PORT="9080"
JENKINS_HTTPS_PORT=""
#JENKINS_AJP_PORT="8009"
JENKINS_AJP_PORT="8009"


5.修改jenkins相关目录权限.
修改jenkins权限（JENKINS_USER默认为jenkins） 

chown -R jenkins /usr/lib/jenkins    
chown -R jenkins /var/log/jenkins      
chown -R jenkins /var/lib/jenkins      
chown -R jenkins /var/cache/jenkins


6.启动jenkins服务。


[root@localhost
/]# service jenkins start

Starting Jenkins                                           [确定]


显示如上，说明jenkins启动错误。查询jenkins状态

[root@localhost
/]# service jenkins status

jenkins 已死，但 pid 文件仍存


错误原因：查看jenkins启动日志（/var/log/jenkins/jenkins.log），发现如下错误：

java.io.IOException: Failed to start a listener: winstone.Ajp13ConnectorFactory

解决方法：修改jenkins的ajp端口为""，

[root@localhost /]# vim /etc/sysconfig/jenkins

JENKINS_AJP_PORT=""


再次启动，显示如下：

[root@localhost /]# service jenkins status

jenkins (pid  28852) 正在运行...


表示jenkis启动成功！

7.通过浏览器访问：输入http://192.168.199.219:9080/






再目录/var/lib/jenkins/secrets/initialAdminPassword查询到密码输入即可。

[root@localhost /]# cat  /var/lib/jenkins/secrets/initialAdminPassword
