jenkins

概述

https://www.jenkins.io/doc/book/installing/linux/#red-hat-centos
Jenkins是一个开源的、提供友好操作界面的持续集成(CI)工具，起源于Hudson（Hudson是商用的），主要用于持续、自动的构建/测试软件项目、监控外部任务的运行（这个比较抽象，暂且写上，不做解释）。Jenkins用Java语言编写，可在Tomcat等流行的servlet容器中运行，也可独立运行。通常与版本管理工具(SCM)、构建工具结合使用。常用的版本控制工具有SVN、GIT，构建工具有Maven、Ant、Gradle。

• 报错：
  到网上找了下原因，是因为我jenkins中的没有配置jdk的路径;
  然后修改/etc/init.d/jenkins文件

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
