持续集成-Jenkins安装部署

1. 安装JDK【java8】

1.1. 软件安装

 [yun@mini05 software]# pwd
 /app/software
 [yun@mini05 software]# tar xf jdk1..0_112.tar.gz
 [yun@mini05 software]# ll
 total
 drwxr-xr-x             Dec  : jdk1..0_112
 -rw-r--r--  root root  Mar  : jdk1..0_112.tar.gz
 [yun@mini05 software]# mv jdk1..0_112/ /app/
 [yun@mini05 software]# cd /app/
 [yun@mini05 app]# ll
 total
 drwxr-xr-x          Dec  : jdk1..0_112
 [yun@mini05 app]# ln -s jdk1..0_112/ jdk
 [yun@mini05 app]# ll
 total
 lrwxrwxrwx   root root     May  : jdk -> jdk1..0_112/
 drwxr-xr-x          Dec  : jdk1..0_112

1.2. 环境变量

 [root@mini05 ~]$ pwd
 /app
 [root@mini05 ~]$ ll -d jdk*
 lrwxrwxrwx  yun yun    Mar  : jdk -> jdk1..0_112
 drwxr-xr-x  yun yun  Dec  : jdk1..0_112
 [root@mini05 profile.d]$ pwd
 /etc/profile.d
 [root@mini05 profile.d]$ cat jdk.sh # java环境变量
 export JAVA_HOME=/app/jdk
 export JRE_HOME=/app/jdk/jre
 export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
 export PATH=$JAVA_HOME/bin:$PATH
 
 [root@mini05 profile.d]# source /etc/profile
 [root@mini05 profile.d]$ java -version
 java version "1.8.0_112"
 Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
 Java HotSpot(TM) -Bit Server VM (build 25.112-b15, mixed mode)

2. 安装jenkins

2.1. 软件安装

 [root@mini05 ~]# cd /etc/yum.repos.d/
 [root@mini05 yum.repos.d]# wget http://pkg.jenkins.io/redhat/jenkins.repo
 [root@mini05 yum.repos.d]# rpm --import http://pkg.jenkins.io/redhat/jenkins.io.key
 [root@mini05 yum.repos.d]# yum install -y jenkins

2.2. 启动jenkins

 [root@mini05 ~]# systemctl start jenkins
 Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.
 [root@mini05 ~]# systemctl status jenkins.service  # 查看Jenkins状态【因为有问题】
 ● jenkins.service - LSB: Jenkins Automation Server
    Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)
    Active: failed (Result: exit-code) since Sun -- :: CST; 5s ago
      Docs: man:systemd-sysv-generator()
   Process:  ExecStart=/etc/rc.d/init.d/jenkins start (code=exited, status=/FAILURE)

 Oct  :: mini05 systemd[]: jenkins.service failed.

解决方法修改 jenkins 启动脚本

 [root@mini05 ~]# vim /etc/rc.d/init.d/jenkins
 # 添加了 /app/jdk/bin/java 这样信息
 ………………
 candidates="
 /etc/alternatives/java
 /usr/lib/jvm/java-1.8./bin/java
 /usr/lib/jvm/jre-1.8./bin/java
 /usr/lib/jvm/java-1.7./bin/java
 /usr/lib/jvm/jre-1.7./bin/java
 /usr/bin/java
 /app/jdk/bin/java
 "
 ………………

再次报错修改

 [root@mini05 ~]# systemctl start jenkins
 Warning: jenkins.service changed on disk. Run 'systemctl daemon-reload' to reload units.
 [root@mini05 ~]# systemctl daemon-reload  # 执行该命令

重启Jenkins服务

 [root@mini05 ~]# systemctl stop jenkins
 [root@mini05 ~]# systemctl start jenkins

3. 首次访问Jenkins

 http://10.0.0.15    

根据页面提示找密码，输入即可

离线问题

参考博文：安装Jenkins时不能联网安装插件问题解决

说明：在网上找了很多文章去解决该离线问题，但是最后都没有解决。所以只能进入页面后再手动安装常用插件。
