Linux安装jenkins

inux下安装jenkins有两种方式：

1，通过rpm方式

2,通过war方式

本文是基于war方式，以下是war方式安装的步骤：

1，下载安装配置JDK环境；

具体操作查看笔者Linux下装JDK笔录：

2，下载安装配置Tomcat环境；

具体操作查看笔者Linux安装tomcat笔录：

https://www.jianshu.com/p/f62f75c00c97

3，下载安装jenkins；

1，下载jenkins的war包：

去该地址下载想要安装的版本：

http://mirrors.jenkins.io/war-stable/

这里笔者下载的是2.121.1版本

[root@iZj6c7eeosj2t5vjw8rf4xZ jenkins]# wget http://mirrors.shu.edu.cn/jenkins/war-stable/2.121.1/jenkins.war

2，把jenkins.war包放置到tomcat的webapps目录下面；

[root@iZj6c7eeosj2t5vjw8rf4xZ webapps]# cp -f /opt/frank/jenkins/jenkins.war  /opt/tomcat/webapps/
[root@iZj6c7eeosj2t5vjw8rf4xZ webapps]# ls
docs  examples  host-manager  jenkins.war  manager  ROOT  tatoo

3,启动tomcat；

启动tomcat，tomcat会自动解压war包，生成一个jenkins文件夹，而且Jenkins默认会存放在用户主目录下的.jenkins文件夹中。
如：Linux root用户：/root/.jenkins

tomcat自动解压生成jenkins文件查看：

[root@iZj6c7eeosj2t5vjw8rf4xZ webapps]# ls
docs  examples  host-manager  jenkins  jenkins.war  manager  ROOT  tatoo
[root@iZj6c7eeosj2t5vjw8rf4xZ webapps]# cd jenkins
[root@iZj6c7eeosj2t5vjw8rf4xZ jenkins]# ls
bootstrap             favicon.ico     LogFileOutputStream$1.class  MainDialog$1.class             scripts
ColorFormatter.class  help            LogFileOutputStream$2.class  MainDialog.class               WEB-INF
css                   images          LogFileOutputStream.class    Main$FileAndDescription.class  winstone.jar
dc-license.txt        JNLPMain.class  Main.class                   META-INF
executable            jsbundles       MainDialog$1$1.class         robots.txt

jenkins的.jenkins文件位置

[root@iZj6c7eeosj2t5vjw8rf4xZ jenkins]# cd /root/.jenkins/
[root@iZj6c7eeosj2t5vjw8rf4xZ .jenkins]# ls
config.xml                     jenkins.install.UpgradeWizard.state  nodes                     secrets
hudson.model.UpdateCenter.xml  jobs                                 plugins                   updates
identity.key.enc               logs                                 secret.key                userContent
jenkins.CLI.xml                nodeMonitors.xml                     secret.key.not-so-secret  users

4，如果不知道tomcat的访问端口是什么可以通过以下命令：

[root@iZj6c7eeosj2t5vjw8rf4xZ .jenkins]# ps -ef|grep tomcat

ps -ef|grep java 和 netstat -apn命令：有上可知我们的tomcat端口是8080

4，访问jenkins界面：

在浏览器上输入ip地址http://47.52.41.245:8080/jenkins（http://ip:端口/jenkins）即可访问,如图：

image

首次进入jenkins如要输入密码，密码位置：/root/.jenkins/secrets/initialAdminPassword

通过cat查看密码，复制粘贴进来，点击继续，进入插件选择安装界面，点击安装默认插件，然后进入插件安装界面，安装完插件之后创建账号然后登录；

如果插件安装失败可以去镜像地址下载插件，然后手动上传
