1、80%的物理内存

  /home/tomcat/bin/catalina.sh中添加

  JAVA_OPTS='-Xms256m -Xmx512m'

  管理机：

  JAVA_OPTS='-Xms256m -Xmx1024m'

  支撑机：

  JAVA_OPTS='-Xms256m -Xmx768m'

  测试机：

  export LD_ASSUME_KERNEL = 2.4.1

2、Tomcat自启动设置：

/etc/rc.local文件

 sshd

 touch /var/lock/subsys/local

 /etc/init.d/mysql start

 export JAVA_HOME=/home/j2sdk

 cd /home/tomcat/bin

 ./startup.sh

3、MySQL自启动设置：

/etc/rc.local文件

 /etc/init.d/mysql start

3、设置虚拟路径：

/home/tomcat/conf/server.xml文件：

       </Context>

       <Context path="/backup" docBase="/home/backup" reloadable="false" />

       <Context path="/arbitration" docBase="/home/arbitration" reloadable="true" />

       <Context path="/netbar" docBase="/home/netbar" reloadable="true" />

       <Context path="/beijing" docBase="/home/beijing" reloadable="true" />

     </Host>

   </Engine>

 </Service>

</Server>

4、连接数配置：

/home/tomcat/conf/server.xml文件：

    <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"

              port="8080" minProcessors="5" maxProcessors="75"

              enableLookups="true" redirectPort="8443"

              acceptCount="100" debug="0" connectionTimeout="20000"

              useURIValidationHack="false" disableUploadTimeout="true" URIEncoding="UTF-8"/>

   <!-- Note : To disable connection timeouts, set connectionTimeout value

    to 0 -->

   <!-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->

   <!--

   <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"

              port="8443" minProcessors="5" maxProcessors="75"

              enableLookups="true"

          acceptCount="100" debug="0" scheme="https" secure="true"

              useURIValidationHack="false" disableUploadTimeout="true">

     <Factory className="org.apache.coyote.tomcat4.CoyoteServerSocketFactory"

              clientAuth="false" protocol="TLS" />

   </Connector>

5、管理机root.xml配置

/home/tomcat/bin/root.xml

 <?xml version="1.0" encoding="UTF-8"?>

 <JWCFK> 

   <db>

           <driverName>com.mysql.jdbc.Driver</driverName>

           <connectionURL>jdbc:mysql://192.168.16.20/netbar</connectionURL>

           <connectionParam>useUnicode=true</connectionParam>

           <connectionParam>characterEncoding=gbk</connectionParam>

           <connectionParam>maxRows=10000</connectionParam>

           <user>root</user>

           <password>gtigstarcenter</password>

           <maxConnection>10</maxConnection>

   </db>

 </JWCFK>
