tomcat 經常使用調整

1.設置內存
在catalina.sh第一行加上
JAVA_OPTS="-Xms1024m -Xmx1024m -Xss1024K -XX:PermSize=128m -XX:MaxPermSize=256m"

2.配置 Executor (主要爲了設置併發相關的參數)
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"     maxThreads="500" minSpareThreads="400" />   

3.修改Connector URIEncoding acceptCount enableLookups executor 等屬性
<Connector  executor="tomcatThreadPool"  URIEncoding="UTF-8" 
port="8080" protocol="HTTP/1.1" 
connectionTimeout="20000"  redirectPort="8443"

enableLookups="false"  acceptCount="1000"  />

4.Linux 下 修改tomcat程序權限

bin目錄下面執行:chmod a+x *.sh
