Apache2下负载均衡tomcat
##Apache2下负载均衡tomcat###修改apache httpd.conf 去掉注释#
LoadModule proxy_module modules/mod_proxy.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 proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
#添加 DirectoryIndex #
DirectoryIndex index.jsp
#BalancerMember成员是我们配置的tomcat集群#
ProxyRequests Off
<proxy balancer://cluster>
①BalancerMember ajp://127.0.0.1:9001 loadfactor=1 route=jvm1
</proxy>
#添加Virtual hosts #
检查 -- 去掉注释
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
#在文件（extra/httpd-vhosts.conf）最下面加入#
<VirtualHost *:80>
ServerAdmin weijie@126.com
ServerName localhost
ServerAlias localhost
#下面两个配置对应httpd.conf中的<proxy balancer://cluster> 配置
ProxyPass / balancer://cluster/ stickysession=jsessionid nofailover=On
ProxyPassReverse / balancer://cluster/
</VirtualHost>
