在CentOS7上安装Jenkins
安装
添加yum repos,然后安装
sudowget-O/etc/yum.repos.d/jenkins.repohttp://pkg.jenkins-ci.org/RedHat/jenkins.repo sudorpm--importhttps://jenkins-ci.org/redhat/jenkins-ci.org.keysudoyuminstalljenkins
如果没有java的话要安装java
sudoyuminstalljava
启动和停止
sudoservicejenkinsstart/stop/restart sudochkconfigjenkinson
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-versionjavaversion"1.5.0"gij(GNUlibgcj)version4.4.620110731(RedHat4.4.6-3)
为了正确使用Jenkins:
yumremovejava
然后可以安装openjdk
yuminstalljava-1.7.0-openjdk
正确如下:
java-versionjavaversion"1.7.0_79"OpenJDKRuntimeEnvironment(rhel-2.5.5.1.el6_6-x86_64u79-b14)OpenJDK64-BitServerVM(build24.79-b02,mixedmode)
配置端口
修改/etc/sysconfig/jenkins
:
JENKINS_PORT="8080"
配置java路径
直接启动:
sudoservicejenkinsstart
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:
[root@iZ94xvn71eeZ~]#vim/etc/init.d/jenkins#Setupenvironmentaccordinglytotheconfigurationsettings[-n"$JENKINS_HOME"]||{echo"JENKINS_HOMEnotconfiguredin$JENKINS_CONFIG";if["$1"="stop"];thenexit0;elseexit6;fi;} [-d"$JENKINS_HOME"]||{echo"JENKINS_HOMEdirectorydoesnotexist:$JENKINS_HOME";if["$1"="stop"];thenexit0;elseexit1;fi;}#SearchusableJavaas/usr/bin/javamightnotpointtominimalversionrequiredbyJenkins.#seehttp://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。
