2.安装APR
[root@localhost app]#tar -zxvf apr-1.4.6.tar.gz
[root@localhost app]#cd apr-1.4.6
[root@localhost apr-1.4.6]#./buildconf
buildconf: checking installation...
buildconf: python version 2.6.5 (ok)
buildconf: autoconf not found.
You need autoconf version 2.59 or newer installed
to build APR from SVN.
[root@localhost apr-1.4.6]#yum install autoconf
[root@localhost apr-1.4.6]#./buildconf
buildconf: libtool not found.
You need libtool version 1.4 or newer installed
to build APR from SVN.
[root@localhost apr-1.4.6]#yum install libtool
[root@localhost apr-1.4.6]#./configure
[root@localhost apr-1.4.6]# make
-bash: make: command not found
[root@localhost apr-1.4.6]#yum install make
[root@localhost apr-1.4.6]# make
[root@localhost apr-1.4.6]# make install
3.安装APR Utils
[root@localhost app]# tar -zxvf apr-util-1.4.1.tar.gz [root@localhost app]# cd apr-util-1.4.1 [root@localhost apr-util-1.4.1]#./buildconf --with-apr=/app/apr-1.4.6 [root@localhost apr-util-1.4.1]# ./configure --with-apr=/app/apr-1.4.6 [root@localhost apr-util-1.4.1]#make [root@localhost apr-util-1.4.1]#make install
4.安装Apache Http Server
[root@localhost app]# tar -zxvf httpd-2.2.22.tar.gz [root@localhost app]# cd httpd-2.2.22 [root@localhost httpd-2.2.22]# ./buildconf [root@localhost httpd-2.2.22]# ./configure [root@localhost httpd-2.2.22]# make [root@localhost httpd-2.2.22]# make install
5.安装Apache 和 Tomcat 的连接器Connector
[root@localhost app]tar -zxvf tomcat-connectors-1.2.35-src.tar.gz [root@localhost app]cd tomcat-connectors-1.2.35-src/native [root@localhost native]# ./configure --with-apxs=/usr/local/apache2/bin/apxs [root@localhost native]#make [root@localhost native]#make install
注意：该tar.gz文件里面其实有很多关于配置的详细文档，如果出现问题可以再其中进行查阅,另外，我的编译应该说是成功了，但是生成的文件却不能用，后来是去网上下载了个已经编译好了的才解决的
6.配置Apache Http Server
原文是说Apache 的httpd.conf是在/usr/local/apache2/conf/目录下面， 但是实际上我发现控制Apache的文件却是在/etc/httpd/conf/目录下面，这点还请高手赐教
在文件最后加上下面一句话就可以了
Include conf/mod_jk.conf
7.在httpd.conf文件同一目录下建立mod_jk.conf文件，内容如下：
#load mod_jk Module LoadModule jk_module /usr/local/apache2/modules/mod_jk.so #arrange workers.properties path JkWorkersFile conf/workers.properties JkLogFile /usr/local/apache2/logs/mod_jk.log JkLogLevel info JkMount /* controller JkMount /*.jsp controller JkMount /*.action controller JkMount /*.do controller #JkMount /jkstatus status
8.在httpd.conf同目录下新建 workers.properties文件，内容如下：
worker.list = controller,tomcat1,tomcat2 #server 列表 #========tomcat1======== worker.tomcat1.port=8009 #ajp13 端口号，在tomcat下server.xml配置,默认8009 worker.tomcat1.host=localhost #tomcat的主机地址，如不为本机，请填写ip地址 worker.tomcat1.type=ajp13 worker.tomcat1.lbfactor = 1 #server的加权比重，值越高，分得的请求越多 #========tomcat2======== worker.tomcat2.port=9009 #ajp13 端口号，在tomcat下server.xml配置,默认8009 worker.tomcat2.host=localhost #tomcat的主机地址，如不为本机，请填写ip地址 worker.tomcat2.type=ajp13 worker.tomcat2.lbfactor = 1 #server的加权比重，值越高，分得的请求越多 #========controller,负载均衡控制器======== worker.controller.type=lb worker.controller.balance_workers=tomcat1,tomcat2 #指定分担请求的tomcat worker.controller.sticky_session=1
9.解压apache-tomcat-7.0.27.tar.gz，并copy一份，home目录分别命名为tomcat1，tomcat2
[root@localhost app]# tar -zxvf apache-tomcat-7.0.27.tar.gz [root@localhost app]# mv apache-tomcat-7.0.27 tomcat1 [root@localhost app]# cp -R tomcat1/ tomcat2
10.更改tomcat2的server.xml文件，由于我的两个tomcat是在同一个服务器上，所以要修改下面红颜色的端口，以防端口冲突.
<Server port="9005" shutdown="SHUTDOWN">
<Connector port="9080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
这个是APJ端口：
<Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />
11.下面是关于负载均衡的配置，在2个tomcat的server.xml中：
<!-- You should set jvmRoute to support load-balancing via AJP ie : <Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1"> --> <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2"><!--tomcat2将与tomcat1黏贴session 在这里指定黏贴对象-->
下面这段代码也是必须的，注意端口不能重复：
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<!--
<Manager className="org.apache.catalina.ha.session.BackupManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"
mapSendOptions="6"/>
-->
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.5"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4000" <!--tomcat1将与tomcat2的端口不同-->
selectorTimeout="100"
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=".*/.gif;.*/.js;.*/.jpg;.*/.png;.*/.htm;.*/.html;.*/.css;.*/.txt;"/>
<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
这是最后我遇到的问题和解决方法：
如果mod_jk.so权限组出现问题请使用一下命令：
chcon -t httpd_modules_t /usr/local/apache2/modules/mod_jk.so
错误: undefined symbol: ap_get_server_description
解决办法：下载编译好的文件 http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.30/i586/
如果启动Httpd失败但是没有错误信息，要检查/etc/httpd/logs下的error_log文件
如果是因为SELinux的问题，可以关闭之
