在CentOS 7上安装Jenkins
安装
添加yum repos,然后安装
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.keysudo yum install jenkins
如果没有java的话要安装java
sudo yum install java
启动和停止
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
firewall-cmd --zone=public --add-port=8080/tcp --permanentfirewall-cmd --zone=public --add-service=http --permanentfirewall-cmd --reload
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:
java -versionjava 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:
yum remove java
然后可以安装openjdk
yum install java-1.7.0-openjdk
正确如下:
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)
配置端口
修改/etc/sysconfig/jenkins
:
JENKINS_PORT="8080"
配置java路径
直接启动:
sudo service jenkins start
但是发现启动失败,于是需要配置java位置:
vi /etc/init.d/jenkins
在启动加入本机的java:
[[email protected] ~]# 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.htmlcandidates=" /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。
