jenkins+docker搭建持续集成环境1

1. 安装jenkins

 安装java环境

#解压tar包
[root@jenkins ~]# tar -zxvf  /opt/jdk-8u161-linux-x64.tar.gz -C  /usr/local/

#配置环境变量

[root@jenkins ~]# vi /etc/profile    

export JAVA_HOME=/usr/local/jdk1.8.0_161/
export JRE_HOME=/usr/local/jdk1.8.0_161/jre
export CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH
"/etc/profile" 81L, 2003C written
[root@jenkins ~]# source  /etc/profile
[root@jenkins ~]# java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

 安装jenkins：

#从此处下载 jenkins的rpm包

#用rpm命令安装jenkins

[root@jenkins opt]# rpm -ivh jenkins-2.222.3-1.1.noarch.rpm
warning: jenkins-2.222.3-1.1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID d50582e6: NOKEY

#修改jenkins的java配置地址

[root@jenkins ~]# vi /etc/init.d/jenkins    

candidates="
/etc/alternatives/java

/usr/lib/jvm/jre-1.8.0/bin/java

#启动jenkins

[root@jenkins ~]# systemctl start jenkins

浏览器输入ip:8080/jenkins即可访问jenkins

等待3-5分钟即可进入jenkins

#使用初始密码，解锁jenkins

[root@jenkins jenkins]# cat /var/lib/jenkins/secrets/initialAdminPassword
c7bbfdfdfeda4cee8a22c2f3d76592d7

#也可以通过log查看到

[root@jenkins jenkins]# tail -f /var/log/jenkins/jenkins.log
Please use the following password to proceed to installation:

c7bbfdfdfeda4cee8a22c2f3d76592d7

This may also be found at: /var/lib/jenkins/secrets/initialAdminPassword

选择安装的插件，新手推荐安装第一个

如果下载插件速度太慢可以使用以下方法更新插件源为国内源

更新插件

更新插件国内源：

cd /var/lib/jenkins/updates/

替换指定源

sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

重启jenkins即可。

测试：

创建test测试任务

 

 

 控制台输出“test success！”表示jenkins搭建成功了
