Tomcat配置

werr

1、Tomcat内存参数调整。

1 2 3 4 5 6 7 8 9 10

[iyunv@localhost ~]# vim /usr/local/tomcat/bin/catalina.sh JAVA_OPTS="$JAVA_OPTS -server -Xmn1024M -Xms2096M -Xmx2096M \ -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true \ -Dorg.apache.catalina.connector.RECYCLE_FACADES=false -XX:PermSize=512M \ -XX:MaxPermSize=512M  -XX:+UseConcMarkSweepGC -XX:+UseParNewGC \ -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection \ -XX:CMSFullGCsBeforeCompaction=0 -XX:+CMSClassUnloadingEnabled \ -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly  \ -XX:SurvivorRatio=65536 -XX:MaxTenuringThreshold=0 -XX:CMSInitiatingOccupancyFraction=81 \ -XX:SoftRefLRUPolicyMSPerMB=0 -Xloggc:gc.log -XX:+PrintGCDetails

2、安装tomcat-native以提升tomcat性能
        apr下载地址：http://apache.org/

1 2 3 4 5 6 7 8 9 10 11 12

[iyunv@localhost~]#tar -zxvf apr-1.5.1.tar.gz [iyunv@localhost~]#cd apr-1.5.1 [root@localhostapr-1.5.1]#./configure --prefix=/usr/local/apr   #安装apr可移植运行库 [root@localhostapr-1.5.1]# make [root@localhostapr-1.5.1]# make install [iyunv@localhost~]# cd /usr/local/tomcat/bin/ [iyunv@localhostbin]# tar xf tomcat-native.tar.gz [iyunv@localhostbin]# cd tomcat-native-1.1.29-src/jni/native/ [iyunv@localhostnative]# ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/java [iyunv@localhostnative]# make && make install [iyunv@localhost ~]# vim /etc/profile  #声明环境变量 LD_LIBRARY_PATH=/usr/local/apr/lib

3、配置多实例Tomcat。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

[iyunv@localhost~]# tar xf apache-tomcat-7.0.47.tar.gz -C /usr/local   #解压tomcat到/usr/local目录 [iyunv@localhost~]# cp -r /usr/local/apache-tomcat-7.0.47/ /usr/local/apache-tomcat-7.0.47-2  #配置Tomcat多实例 [iyunv@localhost~]# mv /usr/local/apache-tomcat-7.0.47/ /usr/local/apache-tomcat-7.0.47-1 [iyunv@localhost~]# ln -sv /usr/local/apache-tomcat-7.0.47-1/ /usr/local/tomcat1  #创建软连接，方便管理 [iyunv@localhost~]# ln -sv /usr/local/apache-tomcat-7.0.47-2/ /usr/local/tomcat2 [iyunv@localhost ~]# vim /etc/profile.d/custom.sh   #声明环境变量 CATALINA_HOME_1=/usr/local/tomcat1 CATALINA_HOME_2=/usr/local/tomcat2 JAVA_HOME=/usr/local/java LD_LIBRARY_PATH=/usr/local/apr/lib export CATALINA_HOME_1  CATALINA_HOME_2  JAVA_HOME  LD_LIBRARY_PATH export PATH=$PATH:$JAVA_HOME/bin [iyunv@localhost ~]# . /etc/profile.d/custom.sh  #执行自定义变量脚本，使之生效 [iyunv@localhost~]# vim /usr/local/tomcat1/bin/startup.sh #修改tomcat的启动和关闭脚本，分别指定tomcat实例家目录 export CATALINA_HOME=$CATALINA_HOME_1 [iyunv@localhost ~]# vim/usr/local/tomcat1/bin/shutdown.sh exportCATALINA_HOME=$CATALINA_HOME_1 [iyunv@localhost ~]# vim/usr/local/tomcat2/bin/startup.sh exportCATALINA_HOME=$CATALINA_HOME_2 [iyunv@localhost ~]# vim /usr/local/tomcat2/bin/shutdown.sh exportCATALINA_HOME=$CATALINA_HOME_2 [iyunv@localhost ~]# vim /etc/init.d/tomcat1 #!/bin/sh # Tomcat init script for Linux. # # chkconfig: 2345 96 14 # description: The Apache Tomcat servlet/JSP container. JAVA_HOME=/usr/local/java CATALINA_HOME=/usr/local/tomcat1 LD_LIBRARY_PATH=/usr/local/apr/lib export JAVA_HOME CATALINA_HOME LD_LIBRARY_PATH exec $CATALINA_HOME/bin/catalina.sh $* [iyunv@localhost ~]# vim /etc/init.d/tomcat2 #!/bin/sh # Tomcat init script for Linux. # # chkconfig: 2345 96 14 # description: The Apache Tomcat servlet/JSP container. JAVA_HOME=/usr/local/java CATALINA_HOME=/usr/local/tomcat2 LD_LIBRARY_PATH=/usr/local/apr/lib export JAVA_HOME CATALINA_HOME LD_LIBRARY_PATH exec $CATALINA_HOME/bin/catalina.sh $* [iyunv@localhost~]# vim /usr/local/tomcat2/conf/server.xml   #修改tomcat2默认端口号               …………               <Server port="8006"shutdown="SHUTDOWN">                        …………                      <Connectorport="8081" protocol="HTTP/1.1"                             …………                             <Connectorport="8010" protocol="AJP/1.3" redirectPort="8443"/>

4、配置redis session共享。

1 2 3 4 5 6 7 8 9 10

配置redis session共享，把以下3个jar包放到2个tomcat实例的库$CATALINA_HOME_1/lib/   $CATALINA_HOME_2/lib/           commons-pool-1.6.jar jedis-2.1.0.jar tomcat-redis-session-manager-1.1.jar    然后修改$CATALINA_HOME/conf/context.xml指定redis服务器路径    <ValveclassName="com.radiadesign.catalina.session.RedisSessionHandlerValve"/>       <ManagerclassName="com.radiadesign.catalina.session.RedisSessionManager"database="0" host="192.168.1.1"maxInactiveInterval="1800" port="1234"/>

5、日志分割。

1 2 3 4

[iyunv@localhost ~]# tar xf cronolog-1.6.2.tar.gz   #安装cron日志分割工具 [iyunv@localhost ~]# cd cronolog-1.6.2 [iyunv@localhost cronolog-1.6.2]# ./configure [iyunv@localhost cronolog-1.6.2]# make && make install
