wget http://blog.s135.com/soft/linux/nginx_php/mhash/mhash-0.9.9.9.tar.gz

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：

tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../

./stdio.h:1010:1: 错误： ‘gets’未声明(不在函数内) 进入srclib目录 执行 sed -i -e '/gets is a security/d' ./stdio.in.h

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 ../../

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 -s /sbin/nologin mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-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 && make install
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：

/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：

vi /var/mysql/my.cnf

启动MySQL：

/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

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

php安装

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/pdo/PDO_MYSQL-1.0.2.tgz
wget http://blog.s135.com/soft/linux/nginx_php/imagick/ImageMagick.tar.gz
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

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
make install
cd ../

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 ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_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
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/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
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-20100525/" 　　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

/usr/local/tengine/sbin

6）配置eAccelerator加速PHP：

mkdir -p /usr/local/eaccelerator_cache vi /usr/local/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：

[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"

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

/usr/sbin/groupadd www
/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

3） 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：

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

输入以下内容：

user  www www;

#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

#user  nobody;
worker_processes  8;

#error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

error_log /var/log/nginx/nginx_error.log  crit;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  /var/webroot/log/host.access.log  main;

        location / {
            root   /var/webroot/web;
            index  index.html index.htm index.php;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
            root           /var/webroot/web;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            #include        fastcgi_params;
        include fcgi.conf;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /\.ht {
            deny  all;
        }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

    location ~ .*\.(js|css)?$
        {
            expires      1h;
        }
    }

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    # HTTPS server
    #
    #server {
    #    listen       443;
    #    server_name  localhost;

    #    ssl                  on;
    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

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

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

ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

4 配置开机自动启动Nginx + PHP

vi /etc/rc.local

在末尾增加以下内容：

ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
/var/mysql/mysql start

5 优化Linux内核参数

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：

/sbin/sysctl -p

6 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：

/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：

/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：

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/nginx/nginx.pid`
