1.设置内存 在catalina.sh第一行加上 JAVA_OPTS="-Xms1024m -Xmx1024m -Xss1024K -XX:PermSize=128m -XX:MaxPermSize=256m" 2.配置 Executor (主要为了设置并发相关的参数) <Executor name="tomcatThreadPool" namePrefix="catalina-exec-"     maxThreads="500" minSpareThreads="400" />    3.修改Connector URIEncoding acceptCount enableLookups executor 等属性 <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程序权限
