Java内存相关的几个配置

  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>
