Jenkins安装部署-白红宇

　官方文档：https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Red+Hat+distributions#InstallingJenkinsonRedHatdistributions-ImportantNoteonCentOSJava

　安装jenkins

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.reposudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.keysudo yum install jenkins

　　这里需要注意的是java的版本要求。

　　类似于

java -versionjava version "1.5.0"gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3)

　jenkins需要GCJ版本的Java，不支持GNU版本的Java。因而需要注意

　正确的版本

java -versionjava version "1.7.0_79"OpenJDK Runtime Environment (rhel-2.5.5.1.el6_6-x86_64 u79-b14)OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

　启动、关闭和重启jenkins

sudo service jenkins start/stop/restartsudo chkconfig jenkins on

　启动时报如下异常：

SEVERE: Container startup failedjava.io.IOException: Failed to start Jetty        at winstone.Launcher.

　查找jenkins配置文件

[root@xxxxxxx ~]# find / -name jenkins/usr/lib/jenkins/etc/rc.d/init.d/jenkins/etc/logrotate.d/jenkins/etc/sysconfig/jenkins/var/lib/jenkins/var/lib/yum/repos/x86_64/6/jenkins/var/cache/jenkins/var/cache/yum/x86_64/6/jenkins/var/log/jenkins

　修改jenkins端口

vi /etc/sysconfig/jenkins

　JENKINS_PORT修改为指定端口

　重启

service jenkins start

　将端口添加到防火墙并重启

　通过http://ip:端口，进行访问即可
