Apache & Tomcat 集群

相关软件及版本：

JDK：jdk-8u151-windows-x64.exe

apache: httpd-2.2.34-win64.zip

tomcat: apache-tomcat-7.0.53-windows-x64.zip

Connectors (mod_jk)：mod_jk-1.2.40-win64.zip

步骤：

1.Apache 及、Tomcat、连接器的下载安装，不做介绍；

# Load mod_jk2 module
LoadModule jk_module modules/mod_jk.so

# Where to find workers.properties( 引用 workers 配置文件 )
JkWorkersFile conf/workers.properties

# Where to put jk logs(log 文件路径 )
JkLogFile logs/mod_jk2.log

# Set the jk log level [debug/error/info](log 级别 )
JkLogLevel info

# Select the log format(log 格式 )
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"

# Send JSPs for context / to worker named loadBalancer(URL 转发配置，匹配的 URL 才转发到 tomcat 进行处理 )
JkMount /*.jsp controller

# JkMount /*.* loadBalancer

6.

#server 列表
worker.list=controller,tomcat1,tomcat2

# tomcat1(ajp13 端口号，在tomcat下server.xml配置,默认8009)
worker.tomcat1.port=8009

#tomcat 的主机地址，如不为本机，请填写ip地址
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13

#server 的加权比重，值越高，分得的请求越多
worker.tomcat1.lbfactor=1

# tomcat2
worker.tomcat2.port=9009
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1

# controller( 负载均衡控制器)
worker.controller.type=lb

# 指定分担请求的tomcat
worker.controller.balanced_workers=tomcat1,tomcat2

#worker.controller.sticky_session=true
