环境

Test on alfresco projects
httpd-2.4.25-win64-VC14.zip
apache-tomcat-6.0.48-windows-x64.zip
mod_jk-1.2.42-win64-VC14.zip

步骤

1. 使用集群，确保`web.xml`中一定要有`<distributable/>`

2. 对`Tomcat的server.xml文件`进行配置

如果单机启动多个Tomcat。避免端口冲突，尽量配置每个Tomcat端口不一样
修改Engine 节点，添加jvmRoute属性。值和apache httpd mod_jk 中的worker名字对应，必须样一样

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
......
</Engine>

server.xml文件中找到被注释掉的<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>在注释行的下面添加如下代码

摘自：http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
                 channelSendOptions="8">

          <Manager className="org.apache.catalina.ha.session.DeltaManager"
                   expireSessionsOnShutdown="false"
                   notifyListenersOnReplication="true"/>

          <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Membership className="org.apache.catalina.tribes.membership.McastService"
                        address="228.0.0.4"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="auto"
                      port="4000"
                      autoBind="100"
                      selectorTimeout="5000"
                      maxThreads="6"/>

            <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
              <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
            </Sender>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
          </Channel>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=""/>
          <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                    tempDir="/tmp/war-temp/"
                    deployDir="/tmp/war-deploy/"
                    watchDir="/tmp/war-listen/"
                    watchEnabled="false"/>

          <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
        </Cluster>

3. 配置Apache httpd

1. 解压httpd-2.4.25-win64-VC14.zip

2. 修改配置文件`Apache24/conf/httpd.conf`

配置ServerRoot
ServerRoot "E:/My-Resources/Apache/httpd-2.4.25-win64-VC14/Apache24"
配置Listen
Listen 192.168.10.152:1314
配置ServerName
ServerName 192.168.10.152:1314
Directory添加allow from all值

<Directory />
    AllowOverride none
    Require all denied
    allow from all
</Directory>

配置DocumentRoot

DocumentRoot"E:/My-Resources/Apache/httpd-2.4.25-win64-VC14/Apache24/htdocs"

<Directory "E:/My-Resources/Apache/httpd-2.4.25-win64-VC14/Apache24/htdocs">

    #

    # Possible values for the Options directive are "None", "All",

    # or any combination of:

    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

    #

    # Note that "MultiViews" must be named *explicitly* --- "Options All"

    # doesn't give it to you.

    #

    # The Options directive is both complicated and important.  Please see

    # http://httpd.apache.org/docs/2.4/mod/core.html#options

    # for more information.

    #

    Options Indexes FollowSymLinks

 

    #

    # AllowOverride controls what directives may be placed in .htaccess files.

    # It can be "All", "None", or any combination of the keywords:

    #   AllowOverride FileInfo AuthConfig Limit

    #

    AllowOverride None

 

    #

    # Controls who can get stuff from this server.

    #

    Require all granted

</Directory>

3. 安装Apache httpd服务

dos命令安装 httpd.exe -k install -n Apache
启动服务，浏览器访问测试
httpd安装成功，关闭服务

4. 负载均衡配置

mod_jk配置

解压mod_jk-1.2.42-win64-VC14.zip文件，把mod_jk.so放进Apache24\modules目录中
在Apache24/conf目录下新建mod_jk.conf，workers.properties文件

mod_jk.conf

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties

JkShmFile logs/mod_jk.shm

JkLogFile logs/mod_jk.log

JkLogLevel info

JkMount /* controller

JkMount /jkstatus status

Workers.properties

worker.list=controller,status

worker.maintain=60

#========tomcat1========

worker.tomcat1.type=ajp13     

worker.tomcat1.host=192.168.10.39

worker.tomcat1.port=8017     

worker.tomcat1.lbfactor=1      

#========tomcat2========

worker.tomcat2.type=ajp13

worker.tomcat2.host=192.168.10.44

worker.tomcat2.port=8009

worker.tomcat2.lbfactor=1

#========controller,负载均衡控制器========

worker.controller.type=lb          

worker.controller.balance_workers=tomcat1,tomcat2

worker.controller.sticky_session=true     

#worker.controller.sticky_session_force=1

worker.status.type=status

在httpd.conf的最后添加一行,引入mod_jk.conf配置文件

include conf/mod_jk.conf

分别启动Tomcat，然后启动httpd服务。浏览器地址访问 192.168.10.152:1314/share

附录

Dos命令启动Apache服务: Httpd.exe -w -n “Apache” -k start
参考：http://www.cnblogs.com/icenter/p/5328383.html

问题

dos命令安装httpd服务；httpd.exe -k install -n Apache提示丢失dll文件

解决办法： 下载vc++2015并安装 https://www.microsoft.com/zh-cn/download/confirmation.aspx?id=48145

安装成功启动服务报错

解决办法： 使用doc命令启动httpd.exe

通过输出信息，检查配置文件定位问题
