tomcat内存设置

1.以startup.bat手动启动

内存设置可修改tomcat_home\bin\catalina.bat

2.做成windows服务启动

(1)打开运行窗口，输入regedit

(2) 进入HKEY_LOCAL_MACHINE/SOFTWARE/Apache Software Foundation/Procrun 2.0/Tomcat7/Parameters/Java

(3)添加需要设置的选项

Tomcat7/Parameters/Java下有三个选项Xms,Xmx,Options

 

Xms设置jvm分配的最小内存，Xmx为最大内存，Options设置java的其他选项(此处格式为每行一项且不能空格)如：

-XX:PermSize=64M
-XX:MaxNewSize=128M
-XX:MaxPermSize=128M
-XX:+CMSPermGenSweepingEnabled
-XX:+CMSClassUnloadingEnabled
-XX:+UseConcMarkSweepGC
-XX:ParallelGCThreads=20
-XX:+UseParNewGC
-XX:TargetSurvivorRatio=90
-XX:MaxTenuringThreshold=31
-Djava.awt.headless=true

 
3.查看内存使用状态： 
(1).修改TOMCAT_HOME/conf/tomcat-users.xml 

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager-gui"/>
  <role rolename="manager-status"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
  <user username="tomcat" password="tomcat" roles="manager-gui"/>
  <user username="tomcat" password="tomcat" roles="manager-gui"/>

(2) 进入http://localhost:8080/manager/status
