Tomcat常用配置

JVM

vi catalina.sh
JAVA_OPTS="-Xms1024m  -Xmx1024m  -XX:MaxNewSize=512m -XX:MaxPermSize=512m  -Djava.awt.headless=true  -Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8"
cygwin=false

server.xml

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" useBodyEncodingForURI="true" URIEncoding="UTF-8"  />
<Context path="" reloadable="true" docBase="/opt/java/webapp" crossContext="true"/>

并发优化

<Connector port="80" protocol="org.apache.coyote.http11.Http11NioProtocol"
               connectionTimeout="20000"  enableLookups="false" maxThreads="1024" minSpareThreads="25"  maxSpareThreads="75"  acceptCount="100"
               redirectPort="8443" useBodyEncodingForURI="true" URIEncoding="UTF-8"  />

二级域名session共享配置
