[jenkins]解决jenkins内存溢出问题
在jenkins master-slave配置中，总是出现内存溢出问题，更换了机器设备仍然跑不起来：
问题如下：
问题解决方案：服务器端启动war包添加参数，/usr/bin/java -Xms1024m -Xmx1024m -XX:PermSize=512M -XX:PermSize=1024M -jar jenkins.war --httpPort=18080 --ajp13Port=18009
因为单独在slave机器上跑没有问题，所以slave机器可以不加，如果单独在slave机器上单独运行脚本也有内存溢出问题，那么slave执行脚本也要加
