linux tomcat部署问题

linux环境下重新部署新版本项目先后出现如下问题

ps -ef | grep tomcat 发现有好多tomcat进程，不知道是怎么回事（可能是和我部署项目的方法有关系），然后依次kill掉所有的tomcat进程，我还改动了catalina.sh(为解决内存溢出的问题)，改动代码如下，重新用Xshell链接服务器，重新启动项目，就好了。

JAVA_OPTS=’-Xms1024m -Xmx1024m -XX:PermSize=256M -XX:MaxNewSize=512m -XX:MaxPermSize=512m’

思考：内存溢出的问题应该是多个tomcat进程造成的，jar not loaded这个问题原因不得而知。

ps:退出linux远程登录，最好使用exit;不要直接X了。感觉会更好点
