三、安装PHP 5.2.14（FastCGI模式）

 

1，编译安装PHP 5.2.17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 ../

2，tar zxvf libmcrypt-2.5.8.tar.gz 
cd libmcrypt-2.5.8/

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

 

4，
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

 

四、安装mysql-5.6.2-m5

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.6.2-m5-linux2.6-i686.tar.gz
mv mysql-5.6.2-m5-linux2.6-i686 /usr/local/mysql
cd /usr/local/mysql

chown -R mysql .

chgrp -R mysql .

scripts/mysql_install_db --user=mysql

chown -R root .

chown -R mysql data

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

bin/mysqld_safe --user=mysql &

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

echo "/usr/local/lib">> /etc/ld.so.conf

echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf

ldconfig

ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
service mysql start
/usr/local/mysql/bin/mysqladmin -u root password root    //root改为你需要的密码
service mysql restart

 

五，编译安装PHP（FastCGI模式）

tar zxvf php-5.2.17.tar.gz

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

cd php-5.2.17

./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 --enable-ftp

 

make ZEND_EXTRA_LIBS='-liconv'

make install

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

cd ../

 

 

 

六，编译安装php5扩展库

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-0.9.6.1.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 ../

 

 

七，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。

 

 

八、配置eAccelerator加速PHP：

 

 

mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/etc/php.ini

在php.ini中添加以下内容

[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"

 

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www

 

 

 

九、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）：

<?xml version="1.0" ?>
<configuration>

    </section>

  </workers>

</configuration>

 

 

十、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

　注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。

注意问题：

引用

如果出现下面的错误(这个错误是我在安装过程中发现的，是内在不足导致的，在文章的结尾优化后，就不会有这样的问题了，在这里做个记录，方便大家学习) 
Starting php_fpm eAccelerator: Could not allocate 67108864 bytes, the maximum size the kernel allows is 33554432 bytes. Lower the amount of memory request or increase the limit in /proc/sys/kernel/shmmax. 
PHP Warning:  [eAccelerator] Can not create shared memory area in Unknown on line 0 
PHP Fatal error:  Unable to start eAccelerator module in Unknown on line 0 
failed


#说明
php.ini中设置的eAccelerator，eaccelerator.shm_size="64"，解释：eaccelerator可使用的共享内存大小(单位为MB)，即64M
在Linux下，单个进程的最大内存使用量受/proc/sys/kernel/shmmax中设置的数字限制(单位为字节)  /proc/sys/kernel/shmmax = 33554432 （32M）
临时更改该值：
echo 128000000 > /proc/sys/kernel/shmmax
或者
vi /etc/sysctl.conf
kernel.shmmax = 128000000
syscatl -p

十一、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/nginx --with-http_stub_status_module --with-http_ssl_module   --with-http_gzip_static_module
make && make install
cd ../

3、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/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/nginx_error.log  crit;

pid        /usr/local/nginx/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;
  fastcgi_intercept_errors on;

  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;
  access_log   off;

  server
  {
    listen       80;
    server_name  www.dzhope.com;
    index index.html index.htm index.php;
    root  /home/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;
    }    

   }

  server
  {
    listen  80;
    server_name  status.dzhope.com;

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

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

 

 

 

十二、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

十三、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

十四、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/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：
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
