二、安装PHP需要的库程序

cdlibiconv-1.13.1/&&./configure--prefix=/usr/local

make&&makeinstall&&cd..

cdlibmcrypt-2.5.8/&&./configure

make&&makeinstall

/sbin/ldconfig&&cdlibltdl/&&./configure--enable-ltdl-install

make&&makeinstall&&cd../..

cdmhash-0.9.9.9/&&./configure

make&&makeinstall&&cd..

ln-s/usr/local/lib//usr/lib/

ln-s/usr/local/lib//usr/lib/

ln-s/usr/local/lib/.4/usr/lib/.4

ln-s/usr/local/lib/.4.4.8/usr/lib/.4.4.8

ln-s/usr/local/lib/libmhash.a/usr/lib/libmhash.a

ln-s/usr/local/lib//usr/lib/

ln-s/usr/local/lib/.2/usr/lib/.2

ln-s/usr/local/lib/.2.0.1/usr/lib/.2.0.1

ln-s/usr/local/bin/libmcrypt-config/usr/bin/libmcrypt-config

cdmcrypt-2.6.8/&&/sbin/ldconfig

./configure&&make&&makeinstall&&cd..

三、编译安装MySQL

&&cdmysql-5.1.57

./configure--prefix=/usr/local/webserver/mysql/--enable-assembler--with-extra-charsets=complex

--enable-thread-safe-client--with-big-tables--with-readline--with-ssl--with-embedded-server

--enable-local-infile

make&&makeinstall&&cd..

创建mysql用户组，创建数据库、日志等存储目录并赋予权限

mkdir-p/data/mysqldata

mkdir-p/data/mysqldata/database

mkdir-p/data/mysqldata/log

mkdir-p/data/mysqldata/pid

groupaddmysql

useradd-gmysql-d/data/mysqldata/database-s/sbin/nologinmysql

chgrp-Rmysql/usr/local/webserver/mysql/.

chown-Rroot:mysql/usr/local/webserver/mysql/*

chown-Rmysql:mysql/data/mysqldata/*

修改文件参数（参数适用于大于2G内存服务器）

[client]

port=3306

socket=/tmp/

[mysqld]

user=mysql

port=3306

socket=/tmp/

basedir=/usr/local/webserver/mysql

datadir=/data/mysqldata/database

log-error=/data/mysqldata/log/mysql_

pid-file=/data/mysqldata/pid/

skip-external-locking

skip-name-resolve

back_log=500

key_buffer_size=256M

max_allowed_packet=32M

thread_stack=192K

table_cache=256

sort_buffer_size=4M

read_buffer_size=4M

join_buffer_size=4M

read_rnd_buffer_size=8M

myisam_sort_buffer_size=64M

thread_cache=128

thread_cache_size=10

query_cache_size=32M

tmp_table_size=128M

max_connections=5000

wait_timeout=60

max_connect_errors=6000

expire_logs_days=30

server-id=1

[mysqldump]

quick

max_allowed_packet=32M

[mysql]

no-auto-rehash

初始化MySQL服务

/usr/local/webserver/mysql/bin/mysql_install_db

--basedir=/usr/local/webserver/mysql

--datadir=/data/mysqldata/database

--user=mysql

启动MySQL服务

/usr/local/webserver/mysql/bin/mysqld_safe--user=mysql&//启动服务

/usr/local/webserver/mysql/bin/mysqladmin-uroot-pshutdown//停止服务

修改root密码

/usr/local/webserver/mysql/bin/mysqladmin-urootpassword‘yourpassword’

四、编译安装PHP（FastCGI模式）

|patch-dphp-5.2.17-p1

cdphp-5.2.17/

./buildconf--force

./configure--prefix=/usr/local/webserver/php

--with-config-file-path=/usr/local/webserver/php/etc

--with-mysql=/usr/local/webserver/mysql

--with-mysqli=/usr/local/webserver/mysql/bin/mysql_config

--with-gd

--with-jpeg-dir

--with-iconv-dir=/usr/local

--with-libxml-dir=/usr

--with-zlib

--with-png-dir

--with-curl

--with-ldap

--with-xmlrpc

--with-openssl

--with-mhash

--with-mcrypt

--with-freetype-dir

--with-ldap-sasl

--with-curlwrappers

--enable-xml

--enable-shared

--enable-discard-path

--enable-safe-mode

--enable-bcmath

--enable-shmop

--enable-sysvsem

--enable-inline-optimization

--enable-mbregex

--enable-fastcgi

--enable-fpm

--enable-force-cgi-redirect

--enable-mbstring=all

--enable-gd-native-ttf

--enable-pcntl

--enable-sockets

--enable-zip

--enable-soap

makeZEND_EXTRA_LIBS='-liconv'

makeinstall&&cd..

五、安装PHP扩展模块

cdmemcache-2.2.6/

/usr/local/webserver/php/bin/phpize

./configure--with-php-config=/usr/local/webserver/php/bin/php-config

make&&makeinstall&&cd..

tarzxvfPDO_

cdPDO_MYSQL-1.0.2/

/usr/local/webserver/php/bin/phpize

./configure

--with-php-config=/usr/local/webserver/php/bin/php-config

--with-pdo-mysql=/usr/local/webserver/mysql

make&&makeinstall&&cd..

2

cdeaccelerator-0.9.6.1/

/usr/local/webserver/php/bin/phpize

./configure--enable-eaccelerator=shared

--with-php-config=/usr/local/webserver/php/bin/php-config

make&&makeinstall&&cd..

cdImageMagick-6.7.0-8/

./configure&&make&&makeinstall&&cd..

cdimagick-3.0.0/

/usr/local/webserver/php/bin/phpize

./configure--with-php-config=/usr/local/webserver/php/bin/php-config

make&&makeinstall&&cd..

修改文件

vim/usr/local/webserver/php/etc/

查找:

extension_dir="./"

修改为:

extension_dir="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"

并在此行后增加以下几行，然后保存：

extension=""

extension="pdo_"

extension=""

再查找：output_buffering=Off

修改为：output_buffering=On

创建缓存目录，配置eAccelerator加速PHP:

mkdir-p/usr/local/webserver/eaccelerator_cache

将以下参数添加到文件末尾

zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts

-20060613/"

_size="64"

_dir="/usr/local/webserver/eaccelerator_cache"

="1"

zer="1"

_mtime="1"

="0"

=""

_max="0"

_ttl="3600"

_prune_period="3600"

_only="0"

ss="1"

ss_level="9"

修改配置文件

vim/usr/local/webserver/php/etc/

如果安装Nginx+PHP用于程序调试，请将以下的

0

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

启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可

以只开启64个进程），用户为：www

ulimit-SHn65535

/usr/local/webserver/php/sbin/php-fpmstart//在www用户创建之后在开启。

注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，

修改后不重启php-cgi，重新加载配置文件使用reload。

六、编译安装nginx

创建www用户和组，以及网站目录，日志目录

groupaddwww

useradd-gwww-s/sbin/nologinwww

mkdir-p/data/wsdata/wwwroot

mkdir-p/data/wsdata/wwwroot/error

echo"404">/data/wsdata/wwwroot/error/

echo"serveristoobusy">/data/wsdata/wwwroot/error/

chmod+w/data/wsdata/wwwroot

mkdir-p/data/wslogs/wwwroot

chmod777/data/wslogs/wwwroot

chown-Rwww:www/data/wsdata/wwwroot

&&cdpcre-8.12/

./configure&&make&&makeinstall&&cd..

&&cdnginx-1.0.2/

./configure

--user=www

--group=www

--prefix=/usr/local/webserver/nginx

--with-http_stub_status_module

--with-http_ssl_module

--with-http_flv_module

--with-cc-opt='-O3'

--with-cpu-opt=opteron

--with-http_gzip_static_module

make&&makeinstall&&cd..
