jsp集群基于nginx+tomcat实现高可用性和高性能

目的：搭建高可用、高性能的jsp集群 二、初始化系统 #init system 系统环境: CentOS 5.5（定制安装） 组件： Base Development Libraries Development Tools Editors Text-based Internet ./init_system.sh #此脚本参见http://kerry.blog.51cto.com/172631/555535 三、LVS+keeplived #关于LVS+keeplived的配置请参考我的另一篇博文《CentOS5.5环境下布署LVS+keepalived 》http://kerry.blog.51cto.com/172631/401253 四、nginx、tomcat整合 #config web_1、web_2 #download software cd /opt wget http://labs.renren.com/apache-mirror/tomcat/tomcat-6/v6.0.32/bin/apache-tomcat-6.0.32.tar.gz wget http://download.oracle.com/otn-pub/java/jdk/6u25-b06/jdk-6u25-linux-i586.bin wget http://nginx.org/download/nginx-1.0.0.tar.gz wget http://ftp.exim.llorien.org/pcre/pcre-8.12.tar.gz wget http://apache.etoak.com//tomcat/tomcat-connectors/native/1.1.20/source/tomcat-native-1.1.20-src.tar.gz wget http://archive.apache.org/dist/apr/apr-1.4.2.tar.gz wget http://archive.apache.org/dist/apr/apr-util-1.3.9.tar.gz #================================ 1、安装tomcat、JDK ================================= mv apache-tomcat-6.0.32.tar.gz jdk-6u25-linux-i586.bin /usr/local/ tar -zxvf apache-tomcat-6.0.32.tar.gz mv apache-tomcat-6.0.32 tomcat chmod +x jdk-6u25-linux-i586.bin ./jdk-6u25-linux-i586.bin #apr 与 tomcat-native 提供更好的伸缩性、性能和集成到本地服务器技术,如果没有apr技术，启动tomcat 时出现如下提示 #INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/local/jdk1.6.0_25/jre/lib/i386/client:/usr/local/jdk1.6.0_25/jre/lib/i386:/usr/local/jdk1.6.0_25/jre/../lib/i386:/usr/java/packages/lib/i386:/lib:/usr/lib rpm -e --nodeps apr-1.2.7-11.el5_3.1 rpm -e --nodeps apr-1.2.7-11.el5_3.1
