Jenkins安装部署

　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.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins

　　这里需要注意的是java的版本要求。

　　类似于

java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.  (Red Hat 4.4.-)

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

　启动、关闭和重启jenkins

sudo service jenkins start/stop/restart
sudo chkconfig jenkins on

　启动时报如下异常：

　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//jenkins
/var/cache/jenkins
/var/cache/yum/x86_64//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
