apache+php+tomcat集群配置

可以参考附件里面的配置进行修改。另请查阅更多配置资料。

一、要使Apache支持php

    1、在httpd.conf最后一行增加如下代码:

# php5 support
LoadModule php5_module D:/php5.6.16/php5apache2_4.dll
AddType application/x-httpd-php .php .html .htm
# configure thepath to php.ini
PHPIniDir "D:/php5.6.16"

    2、修改DirectoryIndex，默认是html，增加php，例如：

 

 

<IfModule dir_module>
    DirectoryIndex index.php index.htm index.html
</IfModule>

    3、php.ini配置不多说，无非是增加各种扩展extension，参考附件里面。

 

 

二、使用mod_proxy进行tomcat的集群配置

    1、在httpd.conf里面，要一行一行的改，比较麻烦，不如就增加一句话，include,所有改动，放入另外一个新文件里面。在httpd.conf最后一行增加一行：

 

include "D:\Apache24\conf\mod_proxy.conf"

    2、在同级目录创建mod_proxy.conf文件，写入如下内容：

 

 

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so
LoadModule socache_dbm_module modules/mod_socache_dbm.so
LoadModule lbmethod_bybusyness_module modules/mod_lbmethod_bybusyness.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
LoadModule lbmethod_bytraffic_module modules/mod_lbmethod_bytraffic.so
LoadModule lbmethod_heartbeat_module modules/mod_lbmethod_heartbeat.so

#虚拟机配置,负载均衡配置
<VirtualHost *:80>
	ServerName imweb.leihailong.com
	ServerAlias imweb.leihailong.com
	#小心，有些地方要有空格，要不然会出错哈哈。
	ProxyPass / balancer://cluster/ stickysession=JSESSIONID|jsessionid nofailover=On
	ProxyPassReverse / balancer://cluster/
	ErrorLog "logs/modproxy_error.log"
	CustomLog "logs/modproxy_access.log" common
</VirtualHost> 

#The ProxyRequests directive should usually be set off when using ProxyPass.
ProxyRequests Off
<proxy balancer://cluster>
	BalancerMember ajp://192.168.2.254:8010 loadfactor=1 route=tomcat1 smax=5 max=20 ttl=120 retry=300 timeout=15
	BalancerMember ajp://192.168.2.254:8011 loadfactor=1 route=tomcat2 smax=5 max=20 ttl=120 retry=300 timeout=15
	# status=+H为配置热备，当所有机器都over时，才会请求该机器
	#BalancerMember http://192.168.2.254:8080 status=+H
	ProxySet lbmethod=byrequests
</proxy>

 

 

三、使用mod_jk进行tomcat的集群配置

     1、在httpd.conf里面，要一行一行的改，比较麻烦，不如就增加一句话，include,所有改动，放入另外一个新文件里面。在httpd.conf最后一行增加一行：

include "D:\Apache24\conf\mod_jk.conf"

    2、在同级目录创建mod_jk.conf文件，写入如下内容：

 

LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkMount /*.jsp controller
JkLogFile logs/mod_jk.log
JkLogLevel info
JkLogStampformat "[%a %b %d %H:%M:%S %Y]"

    3、在同级目录创建workers.properties，写入如下内容：

 

 

worker.list=controller
#========tomcat1========
worker.tomcat1.port=8010
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1

#========tomcat2========
worker.tomcat2.port=8011
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1

#=======balance controller====
worker.controller.type=lb
worker.retries=3
worker.controller.balance_workers=tomcat1,tomcat2
worker.controller.sticky_session=1

 四、配置tomcat集群：

 

    关键点：

     1、端口号修改，避免重复，

     2、jvmRoute="tomcat1"   ，

     3、<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
