本文主要给大家介绍了关于在centos 7安装Jenkins的相关内容，分享出来供大家参考学习，话不多说，来一起看看详细的介绍：
安装
添加yum repos，然后安装
?
| 1 2 3 | sudo wget -O /etc/yum.repos.d/jenkins.repo http: //pkg.jenkins-ci.org/redhat/jenkins.repo sudo rpm -- import https: //jenkins-ci.org/redhat/jenkins-ci.org.key sudo yum install jenkins |
如果没有java的话要安装java
?
| 1 | sudo yum install java |
启动和停止
?
| 1 2 | sudo service jenkins start /stop/restart sudo chkconfig jenkins on |
jenkins的默认设置
•Jenkins会随系统启动而启动。详情参照 /etc/init.d/jenkins
•Jenkins会创建一个用户叫做 jenkins , 如果你修改了user，则要修修改所属者： /var/log/jenkins , /var/lib/jenkins , /var/cache/jenkins
•如果遇到问题，查看日志 /var/log/jenkins/jenkins.log
•配置文件 /etc/sysconfig/jenkins
•默认启用8080
打开和关闭防火墙
?
| 1 2 3 | firewall-cmd --zone=public --add-port=8080 /tcp --permanent firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload |
?
| 1 | firewall-cmd --list-all |
关于centos上的java
Jenkins不支持在centos的默认的jdk上工作。如果如下所示，则需要remove：
?
| 1 2 3 | java -version java version "1.5.0" gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3) |
为了正确使用Jenkins：
?
| 1 | yum remove java |
然后可以安装openjdk
?
| 1 | yum install java-1.7.0-openjdk |
正确如下：
?
| 1 2 3 4 | java -version java 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) |
配置端口
修改 /etc/sysconfig/jenkins :
?
| 1 | JENKINS_PORT= "8080" |
配置java路径
直接启动：
?
| 1 | sudo service jenkins start |
但是发现启动失败，于是需要配置java位置：
?
| 1 | vi /etc/init .d /jenkins |
在启动加入本机的java：
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | [root@iZ94xvn71eeZ ~] # vim /etc/init.d/jenkins # Set up environment accordingly to the configuration settings [ -n "$JENKINS_HOME" ] || { echo "JENKINS_HOME not configured in $JENKINS_CONFIG" ; if [ "$1" = "stop" ]; then exit 0; else exit 6; fi ; } [ -d "$JENKINS_HOME" ] || { echo "JENKINS_HOME directory does not exist: $JENKINS_HOME" ; if [ "$1" = "stop" ]; then exit 0; else exit 1; fi ; } # Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins. # see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html candidates=" /etc/alternatives/java /usr/lib/jvm/java-1 .8.0 /bin/java /usr/lib/jvm/jre-1 .8.0 /bin/java /usr/lib/jvm/java-1 .7.0 /bin/java /usr/lib/jvm/jre-1 .7.0 /bin/java /usr/bin/java /usr/java/jdk1 .7.0_80 /bin/java " |
上述最后一行是我添加的。
重启，可以正常运行了。

启动
浏览器输入ip和端口访问，第一个页面是正在启动，启动结束后会让输入一串密码，然后进入插件安装界面，选择默认，这时候会报错：
An error occurred during installation: Forbidden
解决办法：
I “fixed it” by restarting Jenkins http://localhost:8080/restart 。即重启就可以继续了。
