Jenkins的使用

、Jenkins安装

1）Jenkins介绍

1）一个自动构建过程，包括自动编译，分发，部署和测试，是持续的软件版本发布，测试项目
2）一个代码存储库，即需要版本控制软件来保障代码的可维护性，同时作为构建过程的素材库，例如svn，git代码库
3）监控外部调用执行的工作

2）Jenkins的安装环境

[root@linux-host2 ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core) 
[root@linux-host2 ~]# uname -r
3.10.0-693.el7.x86_64
[root@linux-host2 ~]# uname -m
x86_64
[root@linux-host2 ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

3)Jenkins的安装方法

3.1）yum install jenkins -y 方式

yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm --import http://pkg.jenkins.io/redhat/jenkins.io.key
yum install jenkins -y

3.2）rpm包安装

/etc/logrotate.d/jenkins
/etc/sysconfig/jenkins
/usr/lib/jenkins
/usr/lib/jenkins/jenkins.war
/usr/sbin/rcjenkins
/var/cache/jenkins
/var/lib/jenkins
/var/log/jenkins
[root@linux-host2 tools]# systemctl start jenkins
[root@linux-host2 tools]# ss -lnt

4）启动Jenkins

service jenkins start   # centos6启动
systemctl start jenkins # centos7启动
chkconfig jenkins on    # 设置开机自启动

5）访问Jenkins网页

1.访问Jenkins：10.0.0.101:8080/
2.查找admin默认密码
 cat /var/lib/jenkins/secrets/initialAdminPassword

6）安装默认插件

7) Jenkins的目录文件介绍

[root@linux-host2 tools]# rpm -ql jenkins
/etc/init.d/jenkins            #启动脚本
/etc/logrotate.d/jenkins
/etc/sysconfig/jenkins           #配置文件
/usr/lib/jenkins    
/usr/lib/jenkins/jenkins.war
/usr/sbin/rcjenkins
/var/cache/jenkins          #程序目录
/var/lib/jenkins             #主目录
/var/log/jenkins        #日志文件
[root@linux-host2 tools]# grep ^[a-Z]  /etc/sysconfig/jenkins
JENKINS_HOME="/var/lib/jenkins"
JENKINS_JAVA_CMD=""
JENKINS_USER="jenkins"

执行步骤
1.新版本Jenkins.war包下载地址：http://updates.jenkins-ci.org/download/war/
2.关闭Jenkins。
3.备份原来版本的war包。
4.上传新版本的war包到/usr/lib/jenkins/下

实际命令操作
[root@linux-host2 tools]# systemctl stop jenkins.service 
[root@linux-host2 tools]# ss -lnt|grep 8080
[root@linux-host2 jenkins]# cd /usr/lib/jenkins/
[root@linux-host2 jenkins]# mv jenkins.war jenkins-3.23.2.war

 二、Jenkins的基本使用

1）系统设置

 

 三、插件安装

1）安装gitlab插件

 1.1）插件安装的其他方法

1.2）直接拷贝安装好的插件文件到指定位置重启Jenkins

[root@node01 plugins]# pwd
/var/lib/jenkins/plugins

 1.3）使用git向gitlab拉取代码，可在全局配置私钥。

1.4） 保存，立即构建。测试是否能拉取代码
