在同一台windows上 apache and two tomcat
1. 安装apache2.2
下载 mod_jk.so, put in the directory C:\Apache2.2\modules
2. 修改apche 的 配置文件 http.conf
added following lines
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkMount /*.jsp loadbalancer //注意这个名字和workers.properties文件中的控制器名字一致
JkLogFile logs/mod_jk.log
JkLogLevel warn
3. 新建workers.properties文件, 目录在C:\Apache2.2\conf下
增加下面的内容
# list the workers by name
worker.list=loadbalancer,worker1,worker2
# localhost server 1
# ————————
worker.worker1.port=8019
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor = 1
# localhost server 2
# ————————
worker.worker2.port=8029
worker.worker2.host=localhost
worker.worker2.type=ajp13
worker.worker2.lbfactor = 1 权重, 数字越大,分配的几率越高
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=worker1, worker2
worker.loadbalancer.sticky_session=1
4. 下载tomcat的解压版, 解压在两个不同的目录中
修改Server.xml
tomcat1 修改下列的配置, 主要是改变端口号 jvmRoute
<Server port="8015" shutdown="SHUTDOWN">
<Service name="Tomcat1">
<Connector port="8060" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8019" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Standalone" defaultHost="localhost" jvmRoute="worker1">
tomcat2 修改下列的配置, 主要是改变端口号 jvmRoute
<Server port="8025" shutdown="SHUTDOWN">
<Service name="Tomcat2">
<Connector port="8070" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8029" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Standalone" defaultHost="localhost" jvmRoute="worker2">
5. 启动两个tomcat , run startup.bat
6. 在两个tomcat webapp 下 增加一个jsp 文件
<%
System.out.println("===========================");
%>
7. http://localhost/test/test.jsp
关掉浏览器,再次访问这个地址, 你会发现控制台会轮流打印, 重复刷新的话, 只会在一个控制台上不断打印, 因为 session还是老
session, 所以不会给你分到另外一台tomcat上去
对httd.conf做任何更改后都需要重新启动apache
