• 安装Jenkins


    centos7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.key
    sudo 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 --permanent
    firewall-cmd --zone=public --add-service=http --permanent
    firewall-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 -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:

     

    yum remove java

     

    然后可以安装openjdk

     

    yum install java-1.7.0-openjdk

     

    正确如下:

     

    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:

     

    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:

     

    [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

     

    参考

     

     

    So do it,and change it,no regret!
