2、检查防火墙配置：
设置防火墙
vim/etc/sysconfig/iptables
重启防火墙
/etc/iptablesrestart
查看防火墙
/etc/iptablesstatus
配置例如：
#Firewallconfigurationwrittenbysystem-config-securitylevel
#Manualcustomizationofthisfileisnotrecommended.
*filter

vim/etc/sysconfig/clock修改ZONE="
Asia/Shanghai"
UTC=falseARC=false
ntpdate--systohc
4、设置默认字符集：
修改/etc/sysconfig/i18n:

设置开机启动，在/etc/中加入上面这行
编写/etc/脚本：
vim/etc/memcached
内容如下：
#!
/bin/bash
MEMCACHED=/usr/local/memcached/bin/memcache
RETVAL=0
caseAVG"
$1"
in

mkdir-p/usr/local/jpeg6/lib
mkdir-p/usr/local/jpeg6/include
mkdir-p/usr/local/jpeg6/man
mkdir-p/usr/local/jpeg6/man1

13、安装gd2
cdgd-2.0.36RC1
./configure–prefix=/usr/local/gd–with-jpeg=/usr/local/jpeg6/--with-png–with-zlib–with-freetype=/usr/local/freetype
14、安装libiconv
cdlibiconv-1.13.1
./configure–prefix=/usr/local/iconv&

18、ln-s/usr/local/lib//usr/lib/
19、ln-s/usr/local/lib/.4.4.8/usr/lib/
20、ln-s/usr/local/lib//usr/lib/
21、ln-s/usr/local/lib//usr/lib/
22、ln-s/usr/local/lib//usr/lib/
23、ln-s/usr/local/lib//usr/lib/
24、ln-s/usr/local/lib//usr/lib/安装mhash
cdmhash
25、安装mcrypt
cdmcrypt-2.6.8
26、安装libexpat
cdexpat-2.0.1
./configure--prefix=/usr/local/expat
makeinstall
27、安装libxml2
cdlibxml2-2.7.6
./configure--prefix=/usr/local/libxml2&
28、安装libxslt（不必安装该扩展库）
cdlibxslt-1.1.26
./configure--prefix=/usr/local/libxslt–with-libxml-prefix=/usr/local/libxml2
29、安装php
添加php-fpm补丁，使支持php-fastcgi和fpm创建cgi进程。
对于php需要下载：
5.2.11-cd5.2.11|patch-d-p1
5.3.0–cd5.3.0|patch–d–p1
i.安装php5.3.0
tarjxvf5.2.11-cd5.2.11|patch-d-p1
cdphp-5.2.11
./configure--prefix=/usr/local/php--with-mysql=/usr/local/mysql--with-gd=/usr/local/gd--with-jpeg-dir=/usr/local/jpeg6--with-png-dir=/usr/local/--with-zlib--with-freetype-dir=/usr/local/freetype--with-libxml-dir=/usr/local/libxml2--enable-shared--enable-magic-quotes--with-iconv--without-sqlite--with-mcrypt--with-iconv=/usr/local/iconv--without-pdo-sqlite--with-gettext=/usr--with-curl--with-curlwrappers--enable-mbregex--enable-fastcgi--enable-fpm--enable-force-cgi-redirect--enable-mbstring--with-mhash--enable-pcntl--enable-sockets--with-config-file-path=/usr/local/php/etc--enable-dom--with-xsl=/usr/local/libxslt--disable-simplexml--enable-roxen-zts
如果编译碰到错误：
errorwhileloadingsharedlibraries:
/usr/local/gd/lib/cannotrestoresegmentprotafterreloc:
Permissiondenied
这个错误是因为打开了RedHat的SELinux，但是关闭会导致其他访问权限问题。
所以可以修改
/etc/selinux/config文件中的SELINUX="
为disabled，然后重启。
chcon-ttextrel_shlib_t/usr/local/gd/lib/*
编译安装：
makeZEND_EXTRA_LIBS='
-liconv'
maketest
cp/usr/local/php/etc/
~
30、编译安装PHP5扩展模块2.2.5
cdmemcache-2.2.5/
/usr/local/php/bin/phpize
./configure--with-php-config=/usr/local/php/bin/php-config
编译安装PHP5扩展模块0.9.50.9.5
./configure--enable-eaccelerator=shared--with-php-config=/usr/local/php/bin/php-config
31、编译安装PHP5扩展模块1.0.2
cdPDO_MYSQL-1.0.2/
./configure--with-php-config=/usr/local/php/bin/php-config--with-pdo-mysql=/usr/local/mysql
makeinstall
三、优化配置
1、配置eAccelerator加速PHP
mkdir–p/usr/local/eaccelerator_cache
修改
vim/usr/local/php/etc/
手工修改：
查找/usr/local/php/etc/中的extension_dir="
./"
修改为extension_dir="
/usr/local/php/lib/php/extensions/no-debug-non-zts-/"
并在此行后增加以下几行，然后保存：
extension="
再查找output_buffering=Off
修改为output_buffering=On
按]]键跳到配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension="
="
128"
/usr/local/eaccelerator_cache"
1"
0"
300"
120"
9"
修改配置文件
vi/etc/
输入以下内容
=95
然后执行以下命令使配置生效
/sbin/sysctl–p
创建www用户和组，虚拟主机使用的目录：
/usr/sbin/groupaddwww
/usr/sbin/useradd-gwwwwww
mkdir-p/var/www
chmod750/var/www
chown-Rwww:
www/var/www
创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更配置而无需重启php-cgi）：
在/usr/local/php/etc/目录中创建文件：
rm-f/usr/local/php/etc/
vi/usr/local/php/etc/
输入以下内容（如果您安装Nginx+PHP用于程序调试，请将以下的<
valuename="
display_errors"
>
0<
/value>
改为<
1<
，以便显示PHP错误信息，否则，Nginx会报状态为500的空白错误页）：
