一、网络拓扑:

lvs-master: 192.168.9.201

LVS-backup: 192.168.9.202

LVS-VIP: 192.168.9.200

web_1: 192.168.9.203 web_2: 192.168.9.204

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

compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"

connectionTimeout="20000"

disableUploadTimeout="true"

/>

port：Tomcat服务器监听的端口号

maxHttpHeaderSize：Http的Header的最大限制

enableLookups="false" 使用允许DNS查询，通常情况下设置为false

redirectPort 服务器正在处理http请求时收到了一个SSL传输请求后重定向的端口号

maxThreads Tomcat使用线程来处理接收的每个请求。这个值表示Tomcat可创建的最大的线程数。

acceptCount 指定当所有可以使用的处理请求的线程数都被使用时，可以放到处理队列中的请求数，超过这个数的请求将不予处理。

connectionTimeout 网络连接超时，单位：毫秒。设置为0表示永不超时，这样设置有隐患的。通常可设置为30000毫秒。

minSpareThreads Tomcat初始化时创建的线程数。

maxSpareThreads 一旦创建的线程超过这个值，Tomcat就会关闭不再需要的socket线程。

compression="on" 打开压缩功能

compressionMinSize 启用压缩的输出内容大小，这里面默认为2KB

compressableMimeType压缩类型

#重启tomcat后再次查看 Max threads: 1000
