mac os x 设置 jenkins开机启动遇到的问题

设置命令

取消开机启动

sudo launchctl unload -w /Library/LaunchDaemons/org.jenkins-ci.plist
设置开机启动

sudo launchctl load -w /Library/LaunchDaemons/org.jenkins-ci.plist
我的问题描述

第一次安装jenkins之后，是可以开机启动的，但是由于开机占用400++M内存，就被禁掉了， 然后现在回头想恢复让其开机启动，死活不成功，折腾过程记录如下

查看 plist 文件找出脚本，手工启动

zsh /Library/Application\ Support/Jenkins/jenkins-runner.sh
会出现以下错误

十一月 19, 2014 4:13:10 下午 hudson.UDPBroadcastThread run
警告: UDP handling problem
java.net.SocketException: Can’t assign requested address

at java.net.MulticastSocket.joinGroup(MulticastSocket.java:319)
at hudson.UDPBroadcastThread.run(UDPBroadcastThread.java:76)
这个错误不需要理会

出现错误

解决办法为，增加如下参数

java -Dhudson.DNSMultiCast.disabled=true

/usr/bin/java -Dfile.encoding=UTF-8 -Dhudson.DNSMultiCast.disabled=true -jar /Applications/Jenkins/jenkins.war
恢复jenkins开机启动办法

1.删除文件

sudo rm /Library/LaunchDaemons/org.jenkins-ci.plist
2.重新安装pkg安装包，

通过以上步骤，我的问题解决，祝君好运

3.以上两步是一种解决方法，或者通过 brew install jenkins 重新安装jenkins

4.手工在mac上启动 jenkins

/usr/bin/java -Dfile.encoding=UTF-8 -XX:PermSize=256m -XX:MaxPermSize=512m -Xms256m -Xmx512m -Djava.io.tmpdir=/Users/Shared/Jenkins/tmp -jar /Applications/Jenkins/jenkins.war
