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


Include conf/extra/httpd-info.conf


# Virtual hosts


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.
#

SSLRandomSeed startup builtin
SSLRandomSeed connect builtin




ProxyRequests Off

BalancerMember ajp://10.161.14.55:8055/gis loadfactor=1 route=gis55
BalancerMember ajp://10.161.14.20:8020/gis loadfactor=1 route=gis20




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.


    SetHandler server-status
    Order deny,allow
    Deny from all
 
     
    Allow from [color=blue]all
  [/color]


#
# 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.
#

    SetHandler server-info
    Order deny,allow
    Deny from all
   
   
    Allow from [color=blue]all
   [/color]





SetHandler balancer-manager
Order Deny,Allow
Deny from all
Allow from all





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
#
# 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 block.
#

    ServerAdmin [email protected]
    DocumentRoot "D:/Apache2.2/docs/dummy-host.localhost"
  
   
    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



    ServerAdmin [email protected]
    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




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


port="8055" protocol="AJP/1.3"  
                URIEncoding="UTF-8" 
                redirectPort="8443" />


3.5.2开启Session唯一，粘性会话

    jvmRoute="gis55">

     

    
    
             

     
     
       
       
     

     

       
       

       
       

   

3.6修改JAVAEE应用中WebRoot/WEB-INF/web.xml文件



        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">

    xxx

   
        index.html
        index.htm
   
 
      
    
 


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

#!/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
