1. 安装Apache
我使用的版本是httpd-2.2.15。下载解压后进入httpd的根目录，依次执行如下命令：
$ sudo ./configure --prefix=PREFIX --enable-so --enable-mods-shared=most
$ sudo make
$ sudo make install
启动apache
$ PREFIX/bin/apachectl start
配置为service
将apachectl拷贝到init.d
sudo cp apachectl /etc/init.d/httpd
sudo chkconfig --add httpd
sudo chkconfig httpd on
sudo service httpd start
注意：
1)PREFIX要替换为Apache的安装目录，如/usr/local/apache2.2
2)如果您使用的是httpd2.4，安装包中不包含APR 、APR-Util 和 Perl-Compatible Regular Expressions Library (PCRE)，如系统中未曾安装，需下载安装。
安装apr:
sudo ./configure --prefix=/usr/local/apr
sudo make
sudo make install
安装apr-util:
sudo ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
sudo make
sudo make install
安装pcre：
sudo ./configure --prefix=/usr/local/pcre
sudo make
sudo make install
重新执行命令：
sudo ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --enable-so --enable-mods-shared=most
若启动后报错Failed to lookup provider 'shm' for 'slotmem': is mod_slotmem_shm loaded?
修改httpd.conf配置文件，放开该模块即可。
2. 安装mod_jk
下载mod_jk, 解压后进入native目录，依次执行如下命令：
./configure --with-apxs=/usr/local/apache2.2/bin/apxs
make
编译成功后，进入native/apache-2.0目录，将mod_jk.so拷贝到Apache的modules目录下。
3. 配置mod_jk
在Apache的conf目录中创建三个文件：mod-jk.conf、workers.properties、uriworkermap.properties，内容如下：
mod-jk.conf
# Load mod_jk module
# Update this path to match your modules location
LoadModule jk_module modules/mod_jk.so
# Declare the module for <IfModule directive>
#AddModule mod_jk.c
# Where to find workers.properties
# Update this path to match your conf directory location (put workers.properties next to httpd.conf)
JkWorkersFile conf/workers.properties
# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to access_log)
JkLogFile logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the log format
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"
# Add shared memory.
# This directive is present with 1.2.10 and
# later versions of mod_jk, and is needed for
# for load balancing to work properly
JkShmFile logs/jk.shm
# You can use external file for mount points.
# It will be checked for updates each 60 seconds.
# The format of the file is: /url=worker
# /examples/*=loadbalancer
JkMountFile conf/uriworkermap.properties
# Add jkstatus for managing runtime data
<Location /jkstatus/>
JkMount status
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
workers.properties
# Define list of workers that will be used
# for mapping requests
worker.list=loadbalancer,status
# Define Node1
# modify the host as your host IP or DNS name.
worker.node1.reference=worker.template
worker.node1.host=192.168.50.1
worker.node1.port=8009
worker.node1.lbfactor=1
# Define Node2
# modify the host as your host IP or DNS name.
worker.node2.reference=worker.template
worker.node2.host=192.168.50.2
worker.node2.port=8009
worker.node2.lbfactor=2
worker.template.type=ajp13
worker.template.socket_connect_timeout=5000
worker.template.socket_keepalive=true
worker.template.connection_pool_minsize=0
worker.template.connection_pool_timeout=600
worker.template.ping_mode=A
# Load-balancing behaviour
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=node1,node2
worker.loadbalancer.sticky_session=true
# Status worker for managing load balancer
worker.status.type=status
uriworkermap.properties
/signac-web|/*=loadbalancer
#
# Mount jkstatus to /jkmanager
# For production servers you will need to
# secure the access to the /jkmanager url
#
/jkstatus=status
最后在httpd.conf文件中添加：
Include conf/mod-jk.conf
4、配置EAP
mod_jk使用AJP协议进行通讯，需在web subsystem中配置 ajp connector;
另外需配置jvmRoute，如未配置sticky_session是不起作用的。在EAP6中需添加属性instance-id="node1"(名称要与workers.properties中一致)，如下：
<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false" instance-id="node1">
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>
....
</subsystem>
绑定ajp端口
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
...
<socket-binding name="ajp" port="8009"/>
<socket-binding name="http" port="8080"/>
....
</socket-binding-group>
5、启动jboss和apache
启动apache:
./apachectl start
测试页面：
jkstatus: http://127.0.0.1/jkstatus
signac-web: http://127.0.0.1/signac-web
附：
如使用YUM安装apache，需执行
yum install httpd
yum install httpd-devel
httpd-devel中包含apxs。
