LVS+keeplived+nginx+apache搭建高可用、高性能php集群

      基于PHP的运行环境大家用的比较多的是以apache做中间件的LAMP（linux+apache+mysql+php）环境和以nginx做中间件的LNMP(linux+nginx+mysql+php)环境，apache是世界排名第一的web服务器，apache可以整合大多数应用,比如jsp,php,cgi,python等等,但是apache过于臃肿以及对静态文件响应过于缓慢是让人很不满意的；而nginx作为后起之秀，大有超越前辈的势头，从最近很多门户网站选用nginx就可见一斑，nginx速度快，占用资源少,高性能转发，很高的稳定性,支持热部署，杀手级的proxy和rewrite，但nginx对于php处理依托于fastcgi,fastcgi不够稳定,经常出现502错误,生成相对复杂的页面没有优势,反而会使php-cgi进程变为僵尸进程,多用户多站点的安全性不高，对于其它开发语言的整合，apache表现的更好；综上述对比，为了搭建高性能的php运行环境，就要考虑对apache、nginx进行整合，各取所长，nginx在处理静态内容上的效率较apache强很大，那么就用nginx在前端处理静态文件，把基于php的动态文件转发到后端的apache来处理，接下来我们就开始布署LNAMP（linux+nginx+apache+mysql+php）环境

一、网络拓扑: 

lvs-master: 192.168.9.221
LVS-backup: 192.168.9.222
LVS-VIP: 192.168.9.220

web_server_1: 192.168.9.223
web_server_2: 192.168.9.224
nfs_server_1: 192.168.9.228
nfs_server_1: 192.168.9.229
nfs_vip: 192.168.9.230
mysql_master: 192.168.9.226
mysql_backup: 192.168.9.227
mysql_vip: 192.168.9.225

目的：搭建高可用、高性能的php集群

二、初始化系统
#init system
系统环境: CentOS 5.5 (最小化安装)

./init_system.sh    #此脚本参见http://kerry.blog.51cto.com/172631/555535

#更新组件
sudo -s
LANG=C
yum -y install gcc gcc-c++ bison patch unzip mlocate flex wget automake autoconf gd cpp gettext readline-devel libjpeg \
libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 \
glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel libidn libidn-devel openldap \
openldap-devel openldap-clients openldap-servers nss_ldap expat-devel libtool libtool-ltdl-devel bison

三、LVS+keeplived
#关于LVS+keeplived的配置请参考我的另一篇博文《CentOS5.5环境下布署LVS+keepalived 》http://kerry.blog.51cto.com/172631/401253
