rpm -ivh libgcc-4.2.0-3.aix6.1.ppc.rpm
rpm -ivh libstdcplusplus-4.2.0-3.aix6.1.ppc.rpm
rpm -ivh libstdcplusplus-devel-4.2.0-3.aix6.1.ppc.rpm
rpm -ivh gcc-cplusplus-4.2.0-3.aix6.1.ppc.rpm


2.安装apche
2.1到apache官网http://httpd.apache.org/下载最新版本的httpd-2.2.20.tar.gz
2.2远程登录aix6
telnet 10.161.14.20
输入用户名:root
输入密码: xxx
2.3利用ftp上传httpd-2.2.20.tar.gz到aix6系统中/opt/soft目录下
创建文件夹soft

cd /opt
mkdir soft


2.4解压httpd-2.2.20.tar.gz

cd /opt/soft
gzip -d httpd-2.2.20.tar.gz
tar -xvf httpd-2.2.20.tar


2.5创建apche安装目录

cd /opt
mkdir cist
cd cist
mkdir apache2


2.6拷贝httpd-2.2.20文件到/opt/cist目录下

cd /opt/soft
cp -r httpd-2.2.20 /opt/cist/httpd-2.2.20


2.7配置apche安装环境,编译,安装.

./configure --prefix=/opt/cist/apache2/ --enable-proxy --enable-proxy-ajp --enable-proxy-balancer --enable-proxy-connect --enable-proxy-http --enable-info
make
make install


2.8修改配置文件

cd /opt/cist/apche2/conf
vi httpd.conf

把以下的两行
User daemon
Group daemon
改为
User nobody
Group nobody

3.配置apche负载
3.1修改配置文件httpd.conf

cd /opt/cist/apche2/conf
vi httpd.conf


# Supplemental configuration
#
# The configuration files in the conf/extra/ directory can be
# included to add extra features or to modify the default configuration of
# the server, or you may simply copy their contents here and change as
# necessary.
# Server-pool management (MPM specific)
#Include conf/extra/httpd-mpm.conf
# Multi-language error messages
#Include conf/extra/httpd-multilang-errordoc.conf
# Fancy directory listings
#Include conf/extra/httpd-autoindex.conf
# Language settings
#Include conf/extra/httpd-languages.conf
# User home directories
#Include conf/extra/httpd-userdir.conf
# Real-time info on requests and configuration

<!--取消注释,配置后台监控-->
Include conf/extra/httpd-info.conf

# Virtual hosts

<!--取消注释,配置apche虚拟主机-->
Include conf/extra/httpd-vhosts.conf

# Local access to the Apache HTTP Server Manual
#Include conf/extra/httpd-manual.conf
# Distributed authoring and versioning (WebDAV)
#Include conf/extra/httpd-dav.conf
# Various default settings
#Include conf/extra/httpd-default.conf
# Secure (SSL/TLS) connections
#Include conf/extra/httpd-ssl.conf
#
# Note: The following must must be present to support
#       starting without SSL on platforms with no /dev/random equivalent
#       but a statically compiled-in mod_ssl.
#
<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>

<!--配置AJP分发节点-->
ProxyRequests Off
<proxy balancer://gycluster>
BalancerMember ajp://10.161.14.55:8055/gis loadfactor=1 route=gis55
BalancerMember ajp://10.161.14.20:8020/gis loadfactor=1 route=gis20
</proxy>


3.2开启后台监控
为了了解某个节点负载多少，响应时间多久，服务是否正常呢？Apache提供了负载均衡监控平台,默认情况下服务是关闭的,需要通过修改配置文件开启服务,开启服务后,通过访问http://localhost/balancer-manager就可以查看负载详细情况
除了用于负载均衡还有http://localhost/server-status和http://localhost/server-info
修改配置文件httpd-info.conf

cd /opt/cist/apache2/conf/extra/
vi httpd-info.conf


#
# Get information about the requests being processed by the server
# and the configuration of the server.
#
# Required modules: mod_status (for the server-status handler),
#                   mod_info (for the server-info handler)
#
# Allow server status reports generated by mod_status,
# with the URL of http://servername/server-status
# Change the ".localhost" to match your domain to enable.
<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all

    <!--修改为all,允许所有IP访问. 默认为.localhost只允许localhost访问-->
    Allow from all

</Location>
#
# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information (ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
ExtendedStatus On
#
# Allow remote server configuration reports, with the URL of
#http://servername/server-info (requires that mod_info.c be loaded).
# Change the ".localhost" to match your domain to enable.
#
<Location /server-info>
    SetHandler server-info
    Order deny,allow
    Deny from all
   
    <!--修改为all,允许所有IP访问. 默认为.localhost只允许localhost访问-->
    Allow from all
   
</Location>

<!--开启负载信息监控-->
<Location /balancer-manager>
SetHandler balancer-manager
Order Deny,Allow
Deny from all
Allow from all
</Location>


3.3配置apche虚拟主机
修改配置文件httpd-vhosts.conf

cd /opt/cist/apache2/conf/extra/
vi httpd-vhosts.conf


#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.
#
NameVirtualHost *:80
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.localhost
    DocumentRoot "D:/Apache2.2/docs/dummy-host.localhost"
   
    <!--配置负载均衡节点balancer://gycluster-->
    ServerName localhost
    ServerAlias localhost
    ProxyPass /gygis balancer://gycluster/ stickysession=jsessionid nofailover=On
    ProxyPassReverse /gygis balancer://gycluster/
    ErrorLog "logs/dummy-host.localhost-error.log"
    CustomLog "logs/dummy-host.localhost-access.log" common
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host2.localhost
    DocumentRoot "D:/Apache2.2/docs/dummy-host2.localhost"
    ServerName dummy-host2.localhost
    ErrorLog "logs/dummy-host2.localhost-error.log"
    CustomLog "logs/dummy-host2.localhost-access.log" common
</VirtualHost>

3.4开启/停止apche

cd /opt/cist/apache2/bin
./apachectl -k start
或者
./apachectl -k stop
或者
./apachectl -k restart


3.5配置Tomcat相关模块（AJP）

vi /opt/cist/tomcat7/conf/server.xml   


3.5.1开启AJP配置
<!--修改ajp连接端口-->
<Connector port="8055" protocol="AJP/1.3"   
                URIEncoding="UTF-8"
                redirectPort="8443" />

3.5.2开启Session唯一，粘性会话
    <Engine defaultHost="localhost" name="Catalina" jvmRoute="gis55">
      <!--For clustering, please take a look at documentation at:
          /docs/cluster-howto.html(simple how to)
          /docs/config/cluster.html (reference documentation) -->

   <!--取消注释开启session同步-->
   <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

      <!-- Use the LockOutRealm to prevent attempts to guess user passwords
         via a brute-force attack -->
      <Realm className="org.apache.catalina.realm.LockOutRealm">
      <!-- This Realm uses the UserDatabase configured in the global JNDI
             resources under the key "UserDatabase".Any edits
             that are performed against this UserDatabase are immediately
             available for use by the Realm.-->
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
      <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">
      <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
      <!--
      <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
      -->
      <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
      <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log." resolveHosts="false" suffix=".txt"/>
</Host>
    </Engine>
3.6修改JAVAEE应用中WebRoot/WEB-INF/web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="xxx" version="2.4"
      xmlns="http://java.sun.com/xml/ns/j2ee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   
      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>xxx</display-name>
    <welcome-file-list>
      <welcome-file>index.html</welcome-file>
      <welcome-file>index.htm</welcome-file>
    </welcome-file-list>

   <!--开启分布式处理-->
   <distributable/>

</web-app>
4.AIX重启时,apache自动启动
4.1创建启动脚本

cd /etc
touch rc.apache
chown g+x rc.apache或者 chmod 700 rc.apache
vi rc.apache


<!--创建启动脚本-->
#!/usr/bin/ksh
echo "----------------apache starting---------------------------------"
su - root "-c /opt/cist/apache2/bin/apachectl -k start"
echo "----------------apache start completed---------------------------------"
4.2添加启动脚本到/etc/inittab最下面，实现自启动。并且输出启动日志。

vi /etc/inittab


rc.apache:2:wait:/etc/rc.apache > /dev/console 2>&1
