apache+jboss集群配置

   服务刚从北京搬到本地，原来设想的架构只有一个WEB前台，结果jboss老莫名当机，弄得我们做hosting的忙的焦头烂耳，最后没办法只好先拿备份的那台顶上，弄两个前台，通过apache来集群，具体配置如下：

httpd.conf添加

Include conf/mod_jk2.conf

 

mod_jk2.conf 配置

#mod_jk.so 网上可下载

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers2.properties

JkLogFile logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
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"

JkMount /* loadbalancer

HostnameLookups Off

#apache will serve the static picture.

#by chencj Non-jboss image.
JkUnMount /images/* loadbalancer

.........

#JkUnMount /*.pl loadbalancer
JkUnMount /images/private_root/*     loadbalancer
JkUnMount /images/erased_root/*     loadbalancer

#服务器维护提示页面

JkUnMount /503error/* loadbalancer 

workers2.properties 配置如下：

worker.list=loadbalancer
worker.maintain=60

worker.kd-web.port=8009
worker.kd-web.host=IP1
worker.kd-web.type=ajp13
worker.kd-web.lbfactor=2   #值越大，权中越大
worker.kd-web.local_worker=1
worker.kd-web.cachesize=128
worker.kd-web.socket_timeout=300
worker.kd-web.cache_timeout=600
#worker.kd-web.retries=5

worker.kd-backup.port=8009
worker.kd-backup.host=IP2
worker.kd-backup.type=ajp13
worker.kd-backup.lbfactor=1
worker.kd-backup.local_worker=0
worker.kd-backup.cachesize=128
worker.kd-backup.socket_timeout=300
worker.kd-backup.cache_timeout=600
#worker.kd-backup.retries=5

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=kd-web,kd-backup
#worker.loadbalancer.balanced_workers=kd-web
#worker.loadbalancer.balanced_workers=kd-backup
worker.loadbalancer.sticky_session=1

 

配好以后分别在WEB的jboss-4.0.*SP1/server/default/deploy/jbossweb-tomcat55.sar下的 server.xml 修改如下

另一台的 jvmRoute="kd-backup"

 

完毕重启jboss/apache生效
