2 安装PHP 5.2.14（FastCGI模式）

1）编译安装PHP 5.2.14所需的支持库：

tarzxvf libiconv-1.13.1.tar.gz

cdlibiconv-1.13.1/

./configure--prefix=/usr/local

make

makeinstall

cd../

tarzxvf libmcrypt-2.5.8.tar.gz

cdlibmcrypt-2.5.8/

./configure

make

makeinstall

/sbin/ldconfig

cdlibltdl/

./configure--enable-ltdl-install

make

makeinstall

cd../../

tarzxvf mhash-0.9.9.9.tar.gz

cdmhash-0.9.9.9/

./configure

make

makeinstall

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

tarzxvf mcrypt-2.6.8.tar.gz

cdmcrypt-2.6.8/

/sbin/ldconfig

./configure

make

makeinstall

cd../

2）编译安装MySQL 5.5.3-m3

/usr/sbin/groupaddmysql

/usr/sbin/useradd-g mysql -s /sbin/nologinmysql

tarzxvf mysql-5.5.3-m3.tar.gz

cdmysql-5.5.3-m3/

./configure--prefix=/usr/local/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&& makeinstall

chmod+w /usr/local/mysql

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

cd../

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 /var/mysql/data/

mkdir-p /var/mysql/binlog/

mkdir-p /var/mysql/relaylog/

chown-R mysql:mysql /var/mysql/

②、以mysql用户帐号的身份建立数据表：

1 2	`/usr/local/mysql/bin/mysql_install_db--basedir=/usr/local/mysql--datadir=/var/mysql/data--user=mysql` `/usr/local/mysql/bin/mysql_install_db--basedir=/usr/local/mysql--datadir=/var/mysql/data--user=mysql`

③、创建my.cnf配置文件：

1	`vi/var/mysql/my.cnf`

启动MySQL：

1	`/usr/local/mysql/bin/mysqld_safe--user=root`

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';

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'root';

MYSQL启动脚本

1	`vi/var/mysql/mysql`

#!/bin/sh

mysql_port=3306

mysql_username="root"

mysql_password="root"

function_start_mysql()

{

printf"Starting MySQL...\n"

/usr/local/mysql/bin/mysqld_safe--defaults-file=/var/mysql/my.cnf 2>&1 > /var/mysql/binlog/start.log &

}

function_stop_mysql()

{

printf"Stoping MySQL...\n"

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

}

function_restart_mysql()

{

printf"Restarting MySQL...\n"

function_stop_mysql

sleep5

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: /var/mysql/mysql {start|stop|restart|kill}\n"

fi

php安装

tarzxvf php-5.2.17.tar.gz

gzip-cdphp-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1

cdphp-5.2.17

cpphp.ini-dist /usr/local/php/etc/php.ini

cd../

wget http://blog.s135.com/soft/linux/nginx_php/memcache/memcache-2.2.5.tgz

wget http://blog.s135.com/soft/linux/nginx_php/pcre/pcre-8.10.tar.gz

wget http://blog.s135.com/soft/linux/nginx_php/eaccelerator/eaccelerator-0.9.6.1.tar.bz2

wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.3.0.tgz

4）编译安装PHP5扩展模块

tarzxvf memcache-2.2.5.tgz

cdmemcache-2.2.5/

/usr/local/php/bin/phpize

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

make

makeinstall

cd../

1、安装Nginx所需的pcre库：

tarzxvf pcre-8.10.tar.gz

cdpcre-8.10/

./configure

make&& makeinstall

cd../

tarjxvf eaccelerator-0.9.6.1.tar.bz2

cdeaccelerator-0.9.6.1/

/usr/local/php/bin/phpize

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

make

makeinstall

cd../

tarzxvf PDO_MYSQL-1.0.2.tgz

cdPDO_MYSQL-1.0.2/

/usr/local/php/bin/phpize

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

make

makeinstall

cd../

tarzxvf ImageMagick.tar.gz

cdImageMagick-6.5.1-2/

./configure

make

makeinstall

cd../

tarzxvf imagick-2.3.0.tgz

cdimagick-2.3.0/

/usr/local/php/bin/phpize

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

make

makeinstall

cd../

5）修改php.ini文件

手工修改：查找/usr/local/php/etc/php.ini中的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。
注：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/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#'

/usr/local/php/etc/php.ini

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

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

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

7）创建www用户和组，以及供book.zhiyin.com和www.zhiyin.com两个虚拟主机使用的目录：

/usr/sbin/groupaddwww

/usr/sbin/useradd-g www www

mkdir-p /var/webroot/log

chmod+w /var/webroot/log

chown-R www:www /var/webroot/log

mkdir-p /var/webroot/web

chmod+w /var/webroot/web

chown-R www:www /var/webroot/web

chown-R admin:ftpgroup /var/webroot/web

8）创建Nginx日志目录

mkdir-p /var/log/nginx

chmod+w /var/log/nginx

chown-R www:www /var/log/nginx

4）创建Nginx配置文件

①在/usr/local/nginx/conf/目录中创建nginx.conf文件：

1 2	`rm-f` `/usr/local/nginx/conf/nginx.conf` `vi/usr/local/nginx/conf/nginx.conf`

输入以下内容：

}

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

1	`vi/usr/local/nginx/conf/fcgi.conf`

　输入以下内容：

#fastcgi_param GATEWAY_INTERFACE CGI/1.1;

#fastcgi_param SERVER_SOFTWARE nginx;

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_FILENAME $document_root$fastcgi_script_name;

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 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;

5）启动Nginx

1 2	`ulimit-SHn 65535` `/usr/local/nginx/sbin/nginx`

4 配置开机自动启动Nginx + PHP

1	`vi/etc/rc.local`

在末尾增加以下内容：

ulimit-SHn 65535

/usr/local/php/sbin/php-fpmstart

/usr/local/nginx/sbin/nginx

/var/mysql/mysqlstart

5 在不停止Nginx服务的情况下平滑变更Nginx配置

1）修改

/usr/local/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：

1	`/usr/local/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/nginx/conf/nginx.conf syntax is ok

the configuration file /usr/local/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：

1	`/usr/local/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：

1	`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：

1	`kill-HUP 6302`

或者无需这么麻烦，找到Nginx的Pid文件：

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

6 优化Linux内核参数 (此处内容不推荐使用)

1	`vi/etc/sysctl.conf`

在末尾增加以下内容：

# 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：

1	`/sbin/sysctl-p`

引用来自“mark35”的答案

之所以YUM安装的PHP会有那么多 --disable参数，那是为了你以后单独安装部件考虑的。你可以通过 YUM install php-??? 来安装需要部件，比如

1	`yum` `installphp-mysql php-gd`

相当于只安装了PHP核心，扩展包按需安装

可是我执行了

1	`yum` `installphp-mysql`
