安装步骤：
　　（系统要求：Linux 2.6+ 内核，本文中的Linux操作系统为CentOS 5.3，另在RedHat AS4上也安装成功）

　　一、获取相关开源程序：
　　1、【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库（RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包，进行安装）：

sudo -s

LANG=C

yum -y install gcc gcc-c++ autoconf 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 krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

　　2、【适用RedHat操作系统】RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包（事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在，通常是“xxx-devel”不存在，需要安装）。RedHat可以直接利用CentOS的RPM包安装，以下是RPM包下载网址：
　　①、RedHat AS4 & CentOS 4
　　
　　

　　②、RedHat AS5 & CentOS 5
　　
　　

　　③、RPM包搜索网站
　　
　　

　　④、RedHat AS4 系统环境，通常情况下缺少的支持包安装：
　　Ⅰ、i386 系统

wget

rpm -ivh libjpeg-devel-6b-33.i386.rpm

wget

rpm -ivh freetype-devel-2.1.9-1.i386.rpm

wget

rpm -ivh libpng-devel-1.2.7-1.i386.rpm

　　Ⅱ、x86_64 系统

wget

rpm -ivh libjpeg-devel-6b-33.x86_64.rpm

wget

rpm -ivh freetype-devel-2.1.9-1.x86_64.rpm

wget

rpm -ivh libpng-devel-1.2.7-1.x86_64.rpm

　　3、【适用CentOS、RedHat及其它Linux操作系统】下载程序源码包：
　　本文中提到的所有开源软件为截止到2010年07月26日的最新稳定版。
　　①、从软件的官方网站下载：

mkdir -p /data0/software

cd /data0/software

wget

wget "http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0"

wget "http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz?modtime=1194463373&big_mirror=0"

wget

wget "http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz?modtime=1175740843&big_mirror=0"

wget

　　②、从下载（比较稳定，只允许在本站，或者在Linux/Unix下通过Wget、Curl等命令下载以下软件）：

mkdir -p /data0/software

cd /data0/software

wget

　　二、安装PHP 5.2.14（FastCGI模式）
　　1、编译安装PHP 5.2.14所需的支持库：

tar zxvf libiconv-1.13.1.tar.gz

cd libiconv-1.13.1/

./configure --prefix=/usr/local

make

make install

cd ../

tar zxvf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8/

./configure

make

make install

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd http://www.cnblogs.com/

tar zxvf mhash-0.9.9.9.tar.gz

cd mhash-0.9.9.9/

./configure

make

make install

cd ../

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

tar zxvf mcrypt-2.6.8.tar.gz

cd mcrypt-2.6.8/

/sbin/ldconfig

./configure

make

make install

cd ../

　　2、编译安装MySQL 5.5.3-m3

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

tar zxvf mysql-5.5.3-m3.tar.gz

cd mysql-5.5.3-m3/

./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 --with-plugins=partition,innobase,myisammrg

make && make install

chmod +w /usr/local/webserver/mysql

chown -R mysql:mysql /usr/local/webserver/mysql

cd ../

注：正式版的Mysql5.5编译工具configure改成了cmake, 所以上面的./configure要改成如下：

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DEXTRA_CHARSETS=complex -DWITH_READLINE=1 -DWITH_SSH=system -DWITH_EMBEDDED_SERVER=1 -DENABLE_LOCAL_INFILE=1

configre和cmake的参数对照表，详见：

　　附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。

　　①、创建MySQL数据库存放目录

mkdir -p /data0/mysql/3306/data/

mkdir -p /data0/mysql/3306/binlog/

mkdir -p /data0/mysql/3306/relaylog/

chown -R mysql:mysql /data0/mysql/

　　②、以mysql用户帐号的身份建立数据表：

/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql

　　③、创建my.cnf配置文件：

vi /data0/mysql/3306/my.cnf

　　输入以下内容：

引用

[client]

character-set-server = utf8

port = 3306

socket = /tmp/mysql.sock

[mysqld]

character-set-server = utf8

replicate-ignore-db = mysql

replicate-ignore-db = test

replicate-ignore-db = information_schema

user = mysql

port = 3306

socket = /tmp/mysql.sock

basedir = /usr/local/webserver/mysql

datadir = /data0/mysql/3306/data

log-error = /data0/mysql/3306/mysql_error.log

pid-file = /data0/mysql/3306/mysql.pid

open_files_limit = 10240

back_log = 600

#thread_concurrency = 8

query_cache_size = 512M

query_cache_limit = 2M

query_cache_min_res_unit = 2k

default-storage-engine = MyISAM

thread_stack = 192K

transaction_isolation = READ-COMMITTED

tmp_table_size = 246M

max_heap_table_size = 246M

long_query_time = 3

log-slave-updates

log-bin = /data0/mysql/3306/binlog/binlog

binlog_cache_size = 4M

binlog_format = MIXED

max_binlog_cache_size = 8M

max_binlog_size = 1G

relay-log-index = /data0/mysql/3306/relaylog/relaylog

relay-log-info-file = /data0/mysql/3306/relaylog/relaylog

relay-log = /data0/mysql/3306/relaylog/relaylog

expire_logs_days = 30

key_buffer_size = 256M

read_buffer_size = 1M

read_rnd_buffer_size = 16M

bulk_insert_buffer_size = 64M

myisam_sort_buffer_size = 128M

myisam_max_sort_file_size = 10G

myisam_repair_threads = 1

myisam_recover

interactive_timeout = 120

wait_timeout = 120

skip-name-resolve

#master-connect-retry = 10

slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

#master-host = 192.168.1.2

#master-user = username

#master-password = password

#master-port = 3306

server-id = 1

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 512M

innodb_data_file_path = ibdata1:256M:autoextend

innodb_file_io_threads = 4

innodb_thread_concurrency = 8

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 16M

innodb_log_file_size = 128M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

#log-slow-queries = /data0/mysql/3306/slow.log

#long_query_time = 10

[mysqldump]

quick

max_allowed_packet = 32M

　　④、创建管理MySQL数据库的shell脚本：

vi /data0/mysql/3306/mysql

　　输入以下内容（这里的用户名admin和密码12345678接下来的步骤会创建）：

#!/bin/sh

mysql_port=3306

mysql_username="admin"

mysql_password="12345678"

function_start_mysql()

{

printf "Starting MySQL...\n"

/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &

}

function_stop_mysql()

{

printf "Stoping MySQL...\n"

/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown

}

function_restart_mysql()

{

printf "Restarting MySQL...\n"

function_stop_mysql

sleep 5

function_start_mysql

}

function_kill_mysql()

{

kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')

kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')

}

if [ "$1" = "start" ]; then

function_start_mysql

elif [ "$1" = "stop" ]; then

function_stop_mysql

elif [ "$1" = "restart" ]; then

function_restart_mysql

elif [ "$1" = "kill" ]; then

function_kill_mysql

else

printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"

　　⑤、赋予shell脚本可执行权限：

chmod +x /data0/mysql/3306/mysql

　　⑥、启动MySQL：

/data0/mysql/3306/mysql start

　　⑦、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：

/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

　　⑧、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';

　　⑨、（可选）停止MySQL：

/data0/mysql/3306/mysql stop

　　3、编译安装PHP（FastCGI模式）

tar zxvf php-5.2.14.tar.gz

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/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-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'

make install

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

cd ../

　　4、编译安装PHP5扩展模块

tar zxvf memcache-2.2.5.tgz

cd memcache-2.2.5/

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

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

make

make install

cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2

cd eaccelerator-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

make install

cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz

cd PDO_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

make install

cd ../

tar zxvf ImageMagick.tar.gz

cd ImageMagick-6.5.1-2/

./configure

make

make install

cd ../

tar zxvf imagick-2.3.0.tgz

cd imagick-2.3.0/

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

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

make

make install

cd ../

　　5、修改php.ini文件
　　手工修改：查找/usr/local/webserver/php/etc/php.ini中的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 = "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。

　　自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini

sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini

sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini

sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini

　　6、配置eAccelerator加速PHP：

mkdir -p /usr/local/webserver/eaccelerator_cache

vi /usr/local/webserver/php/etc/php.ini

　　按shift+g键跳到配置文件的最末尾，加上以下配置信息：

引用

[eaccelerator]

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

eaccelerator.shm_size="64"

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

　　7、创建www用户和组，以及供blog.s135.com和两个虚拟主机使用的目录：

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www

mkdir -p /data0/htdocs/blog

chmod +w /data0/htdocs/blog

chown -R www:www /data0/htdocs/blog

mkdir -p /data0/htdocs/www

chmod +w /data0/htdocs/www

chown -R www:www /data0/htdocs/www

　　8、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）：
　　在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：

rm -f /usr/local/webserver/php/etc/php-fpm.conf

vi /usr/local/webserver/php/etc/php-fpm.conf

　　输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

<?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/webserver/php/logs/php-fpm.pid</value>

Error log file

<value name="error_log">/usr/local/webserver/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.

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.

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>

</value>

Unix user of processes

Unix group of processes

Process manager settings

Sets style of controling worker process count.

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

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

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.

Used only when 'apache-like' pm_style is selected

Sets the desired maximum number of idle server processes.

Used only when 'apache-like' pm_style is selected

</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

'0s' means 'off'

The log file for slow requests

Set open file desc rlimit

Set max core size rlimit

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="OSTYPE">$OSTYPE</value>

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

</value>

</section>

</workers>

</configuration>

　　9、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 -SHn 65535

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

　　三、安装Nginx 0.8.46
　　1、安装Nginx所需的pcre库：

tar zxvf pcre-8.10.tar.gz

cd pcre-8.10/

./configure

make && make install

cd ../

　　2、安装Nginx

tar zxvf nginx-0.8.46.tar.gz

cd nginx-0.8.46/

./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

make && make install

cd ../

　　3、创建Nginx日志目录

mkdir -p /data1/logs

chmod +w /data1/logs

chown -R www:www /data1/logs

　　4、创建Nginx配置文件
　　①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：

rm -f /usr/local/webserver/nginx/conf/nginx.conf

vi /usr/local/webserver/nginx/conf/nginx.conf

　　输入以下内容：

引用

}

　　②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：

vi /usr/local/webserver/nginx/conf/fcgi.conf

　　输入以下内容：

引用

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

　　5、启动Nginx

ulimit -SHn 65535

/usr/local/webserver/nginx/sbin/nginx

　　四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

　　在末尾增加以下内容：

引用

ulimit -SHn 65535

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

/usr/local/webserver/nginx/sbin/nginx

　　五、优化Linux内核参数

vi /etc/sysctl.conf

　　在末尾增加以下内容：

引用

# Add

net.ipv4.tcp_max_syn_backlog = 65536

net.core.netdev_max_backlog = 32768

net.core.somaxconn = 32768

net.core.wmem_default = 8388608

net.core.rmem_default = 8388608

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1

#net.ipv4.tcp_tw_len = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30

#net.ipv4.tcp_keepalive_time = 120

net.ipv4.ip_local_port_range = 1024 65535

　　使配置立即生效：

/sbin/sysctl -p

　　六、在不停止Nginx服务的情况下平滑变更Nginx配置
　　1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

/usr/local/webserver/nginx/sbin/nginx -t

　　如果屏幕显示以下两行信息，说明配置文件正确：
　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok

　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully

　　2、平滑重启：
　　①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：

/usr/local/webserver/nginx/sbin/nginx -s reload

　　②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

　　屏幕显示的即为Nginx主进程号，例如：
　　6302
　　这时，执行以下命令即可使修改过的Nginx配置文件生效：

kill -HUP 6302

　　或者无需这么麻烦，找到Nginx的Pid文件：

kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

　　七、编写每天定时切割Nginx日志的脚本
　　1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh

vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

　　输入以下内容：

#!/bin/bash
