Mac OS X 安装Jenkins

Jenkins 是一个开源项目，提供了一种易于使用的持续集成系统，使开发者从繁杂的集成中解脱出来，专注于更为重要的业务逻辑实现上。同时 Jenkins 能实施监控集成中存在的错误，提供详细的日志文件和提醒功能，还能用图表的形式形象地展示项目构建的趋势和稳定性。

Mac OS 10.11.4
Jenkins 1.651.1
tomcat 8
jdk 8

软件准备

下载tomcat

  wget http://apache.mirrors.ionfish.org/tomcat/tomcat-8/v8.0.33/bin/apache-tomcat-8.0.33.zip

解压tomcat

  unaip apache-tomcat-8.0.33.zip
  mv apache-tomcat-8.0.33 tomcat_jenkins

安装JDK

直接去官网下载pkg,安装就可以了.这里不写详细的教程了
安装Jenkins

下载Jenkins,去官网Jenkins

这里直接下载war包, 不要下载Mac OS X,下载完成的到jenkins.war文件

安装,启动 Jenkins

准备jenkins的tomcat

将jenkins.war文件复制到jenkins/tomcat_jenkins/webapps,然后删除ROOT文件, 重命名jenkins.war -> ROOT.war
```
    mv jenkins.war jenkins/tomcat_jenkins/webapps/
    rm -rf ROOT/
    mv jenkins.war ROOT.war
```
配置环境变量

在 jenkins/tomcat_jenkins/bin 目录下新建 setenv.sh 文件，内容如下：
```
  export JENKINS_HOME=/Users/songlijun/Work/Dev/jenkins
```

启动tomcat

  cd jenkins/tomcat_jenkins/bin
  sh ./startup.sh

可能会出现如下错误, 是因为没有设置权限.

  Cannot find ./catalina.sh
  The file is absent or does not have execute permission
  This file is needed to run this program

解决方法,执行如下命令,然后在启动
```
  chmod 777 *.sh
  sh ./startup.sh
```

正确启动

  Using CATALINA_BASE:   /Users/songlijun/Work/Dev/jenkins/tomcat_jenkins
  Using CATALINA_HOME:   /Users/songlijun/Work/Dev/jenkins/tomcat_jenkins
  Using CATALINA_TMPDIR: /Users/songlijun/Work/Dev/jenkins/tomcat_jenkins/temp
  Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home
  Using CLASSPATH:       /Users/songlijun/Work/Dev/jenkins/tomcat_jenkins/bin/bootstrap.jar:/Users/songlijun/Work/Dev/jenkins/tomcat_jenkins/bin/tomcat-juli.jar
  Tomcat started.

正常启动日志如下

  tail -f ../logs/catalina.out
