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）

Text-based Internet
./init_system.sh #此脚本参见/article/4349051.html
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 》/article/4130643.html
四、nginx、tomcat整合

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

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
