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 5.5.2-m2

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.2-m2.tar.gz
cd mysql-5.5.2-m2/
./configure --prefix=/usr/local/mysql --enable-assembler --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --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
chown -R mysql:mysql /usr/local/mysql

/usr/local/mysql/bin/mysql_install_db --user=mysql

cp support-files/my-huge.cnf /etc/my.cnf

vi /etc/my.cnf（优化mysql）

/usr/local/mysql/bin/mysqld_safe --user=mysql &

mysqladmin -uroot –p password 'password';

delete from user where password=’’;

cp /usr/local/mysql/share/mysql/mysql.server /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 2345 mysqld on

3. 编译安装PHP（FastCGI模式）

tar zxvf php-5.2.13.tar.gz
cd php-5.2.13/

patch -p1 <../php-fpm-0.6~5.2.patch

./buildconf --force

./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 --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --with-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 --enable-ftp --with-libevent=shared
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini

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 ../

tar jxvf eaccelerator-0.9.6.tar.bz2
cd eaccelerator-0.9.6/
/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-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

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"

6. 创建www用户和组，以及供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

7. 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/php/etc/目录中创建php-fpm.conf文件：

rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/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）：

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

    Pid file

        /tmp
        /tmp
        $OSTYPE
        $MACHTYPE
        2

8. 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/php/sbin/php-fpm start

三、安装Nginx 0.8.34

1、安装Nginx所需的pcre库：

tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/
./configure
make && make install
cd ../

2、安装Nginx

tar zxvf nginx-0.8.34.tar.gz
cd nginx-0.8.34/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install

3、创建Nginx配置文件

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

输入以下内容：

user  www www;

worker_processes 8;

error_log  /usr/local/nginx/logs/error.log  crit;

pid        /usr/local/nginx/logs/nginx.pid;

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

events
{
  use epoll;
  worker_connections 65535;
}

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  ;
    index index.html index.htm index.php;
    root  /data0/htdocs/blog;

    #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 fcgi.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  /usr/local/nginx/logs/carl_access.log  access;
      }

  server
  {
    listen  80;
    server_name  status.blog.s135.com;

    location / {
    stub_status on;
    access_log   off;
    }
  }
}

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

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

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;

4、启动Nginx

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

四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

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

五、优化Linux内核参数

vi /etc/sysctl.conf

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

/sbin/sysctl –p 使新添加的内核参数生效！

六、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`

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

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

　　输入以下内容：

#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`

　　2、设置crontab，每天凌晨00:00切割nginx访问日志

crontab -e

　输入以下内容：

00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
