一、编译安装nginx

1.安装辅助包

# yum groupinstall "Development Libraries" "Development Tools"

# yum install gcc openssl-devel pcre pcre-devel zlib-devel

2.安装nginx

创建用户和组

# groupadd nginx

# useradd -g nginx -s /bin/false -M nginx

# tar xvf nginx-1.1.3.tar.gz

# cd nginx-1.1.3

# ./configure --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --with-pcre

# make && make install

# vim /etc/init.d/nginx

#!/bin/sh

[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/sbin/nginx"

prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

make_dirs() {

# make required directories

user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=$[^ ]*$.*/\1/g' -`

# chmod +x /etc/init.d/nginx

二、安装mysql（二进制安装）

# tar xvf mysql-5.1.46-linux-i686-glibc23.tar.gz -C /usr/local/

# cd /usr/local/

# ln -sv mysql-5.1.46-linux-i686-glibc23 mysql

# cd mysql

# groupadd mysql

# useradd -g mysql -s /sbin/nologin -M -r mysql

# mkdir /data

# chown -R mysql:mysql /data

# chown mysql:mysql . -R

# scripts/mysql_install_db --user=mysql --datadir=/data

# chown root . -R

# cp support-files/my-large.cnf /etc/my.cnf

# vim /etc/my.cnf

datadir = /data

# bin/mysqld_safe --user=mysql &

# netstat -tnlp

# vim /etc/profile

PATH=$PATH:/usr/local/mysql/bin

# . /etc/profile

# vim /etc/ld.so.conf.d/mysql.conf

/usr/local/mysql/lib

# ldconfig -v

# ln -sv /usr/local/mysql/include/ /usr/include/mysql

# cp support-files/mysql.server /etc/init.d/mysqld

# chkconfig --add mysqld

# chkconfig mysqld on

# service mysqld restart

三、编译安装php （fastcgi模式）

1、编译安装PHP 5.2.14所需的支持库

# tar xvf libiconv-1.13.1.tar.gz

# cd libiconv-1.13.1

# ./configure --prefix=/usr/local

# tar xvf libevent-1.4.14b-stable.tar.gz

# cd libevent-1.4.14b-stable

# ./configure

# make && make isntall

# tar xvf libmcrypt-2.5.8.tar.gz

# cd libmcrypt-2.5.8

# ldconfig -v

# cd libltdl/

# ./configure --enable-ltdl-install

# make && make install

# tar xvf mhash-0.9.9.9.tar.bz2

# cd mhash-0.9.9.9

# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la

# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so

# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4

# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

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

# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la

# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so

# ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

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

2.编译安装php（fastcgi模式）

# tar xvf php-5.2.14.tar.bz2

yum install libxml2-devel

# gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1

# cd php-5.2.14

# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap

# make ZEND_EXTRA_LIBS='-liconv' ##可能是因为机器没有安装libiconv之类的库，怕编译出错，所以不为php加入iconv模块吧。

# make install

# cp php.ini-dist /usr/local/php/etc/php.ini

3.安装php的一些扩展模块儿

# tar xvf mcrypt-2.6.8.tar.gz

# cd mcrypt-2.6.8

# /sbin/ldconfig

# tar zxvf memcache-2.2.5.tgz

# cd memcache-2.2.5/

# /usr/local/php/bin/phpize

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

# make

# tar jxvf eaccelerator-0.9.6.1.tar.bz2

# cd eaccelerator-0.9.6.1/

# ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config

# tar zxvf PDO_MYSQL-1.0.2.tgz

# cd PDO_MYSQL-1.0.2/

# ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql

# tar xvf ImageMagick-6.5.1-2.tar.bz2

# cd ImageMagick-6.5.1-2/

# ./configure

# tar zxvf imagick-2.3.0.tgz

# cd imagick-2.3.0/

4.修改php.ini文件

# vim /usr/local/php/etc/php.ini

查找 extension_dir = "./"

修改为 extension_dir = "/usr/local/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 = "memcache.so"

extension = "pdo_mysql.so"

extension = "imagick.so"

　　再查找 output_buffering = Off

修改为 output_buffering = On

　　再查找 ;cgi.fix_pathinfo=0

修改为 cgi.fix_pathinfo=0 防止Nginx文件类型错误解析漏洞。

5、配置eAccelerator加速PHP

# mkdir -p /usr/local/eaccelerator_cache

在最后添加以下内容

[eaccelerator]

zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="64"

eaccelerator.cache_dir="/usr/local/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="3600"

eaccelerator.shm_prune_period="3600"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

6. 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php.ini配置而无需重启php-cgi）：

# mv /usr/local/php/etc/php-fpm.conf /usr/local/php/etc/php-fpm.conf.bak

# vim /usr/local/php/etc/php-fpm.conf

<?xml version="1.0" ?>

All relative paths in this config are relative to php's install prefix

Pid file

<value name="pid_file">/usr/local/php/logs/php-fpm.pid</value>

Error log file

<value name="error_log">/usr/local/php/logs/php-fpm.log</value>

Log level

<value name="log_level">notice</value>

When this amount of php processes exited with SIGSEGV or SIGBUS ...

... in a less than this interval of time, a graceful restart will be initiated.

Useful to work around accidental curruptions in accelerator's shared memory.

Time limit on waiting child's reaction on signals from master

Set to 'no' to debug fpm

</section>

Name of pool. Used in logs and stats.

<value name="name">default</value>

Address to accept fastcgi requests on.

Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'

Set listen(2) backlog

Set permissions for unix socket, if one used.

In Linux read/write permissions must be set in order to allow connections from web server.

Many BSD-derrived systems allow connections regardless of permissions.

</value>

Additional php.ini defines, specific to this pool of workers.

<value name="sendmail_path">/usr/sbin/sendmail -t -i</value>

Unix user of processes

<value name="user">nginx</value>

Unix group of processes

<value name="group">nginx</value>

Process manager settings

Sets style of controling worker process count.

Valid values are 'static' and 'apache-like'

<value name="style">static</value>

Sets the limit on the number of simultaneous requests that will be served.

Equivalent to Apache MaxClients directive.

Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi

Used with any pm_style.

Settings group for 'apache-like' pm style

Sets the number of server processes created on startup.

Used only when 'apache-like' pm_style is selected

Sets the desired minimum number of idle server processes.

Sets the desired maximum number of idle server processes.

</value>

The timeout (in seconds) for serving a single request after which the worker process will be terminated

Should be used when 'max_execution_time' ini option does not stop script execution for some reason

'0s' means 'off'

The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file

The log file for slow requests

Set open file desc rlimit

Set max core size rlimit

Chroot to this directory at the start, absolute path

Chdir to this directory at the start, absolute path

Redirect workers' stdout and stderr into main error log.

If not set, they will be redirected to /dev/null, according to FastCGI specs

How much requests each process should execute before respawn.

Useful to work around memory leaks in 3rd party libraries.

For endless request processing please specify 0

Equivalent to PHP_FCGI_MAX_REQUESTS

Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.

Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

Makes sense only with AF_INET listening socket.

Pass environment variables like LD_LIBRARY_PATH

All $VARIABLEs are taken from current environment

<value name="HOSTNAME">$HOSTNAME</value>

<value name="PATH">/usr/local/bin:/usr/bin:/bin</value>

<value name="OSTYPE">$OSTYPE</value>

<value name="MACHTYPE">$MACHTYPE</value>

</section>

</workers>

</configuration>

7.启动php-cgi进程，监听127.0.0.1的9000端口，进程数为64（如果服务器内存大于3GB，可以只开启128个进程或者更高，这个根据自己的配置来修改）

# ulimit -SHn 65535

# /usr/local/php/sbin/php-fpm start

# vim /etc/nginx/fastcgi.conf

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param REDIRECT_STATUS 200;

四、配置nginx以提供服务

编辑配置文件

# vim /etc/nginx/nginx.conf

#####以下是本人的配置文档，仅供参考

#user nobody;

worker_processes 4;

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

events

{

worker_connections 51200;

http

include mime.types;

default_type application/octet-stream;

#charset gb2312;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 8m;

sendfile on;

tcp_nopush on;

keepalive_timeout 60;

tcp_nodelay on;

fastcgi_connect_timeout 300;

fastcgi_send_timeout 300;

fastcgi_read_timeout 300;

fastcgi_buffer_size 64k;

fastcgi_buffers 4 64k;

fastcgi_busy_buffers_size 128k;

fastcgi_temp_file_write_size 128k;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_http_version 1.0;

gzip_comp_level 2;

gzip_types text/plain application/x-javascript text/css application/xml;

gzip_vary on;

#limit_zone crawler $binary_remote_addr 10m;

server

{

listen 80;

server_name 192.168.0.90;

index index.html index.htm index.php;

root /nginx;

#limit_conn crawler 20;

location ~ .*\.(php|php5)?$

{

#fastcgi_pass unix:/tmp/php-cgi.sock;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fastcgi.conf;

}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$

{

expires 30d;

location ~ .*\.(js|css)?$

expires 1h;

}

log_format access '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" $http_x_forwarded_for';

access_log /nginx/logs/access.log access;

}

创建日志目录

# mkdir -pv /nginx/logs

# mkdir /var/tmp/nginx/nginx.conf -pv

编辑php测试页

# cd /nginx

# vim index.php

<?php

phpinfo();

启动nginx

# service nginx restart

测试

OK 完美的显示
