Centos 搭建高性能WEB 服务器 Nginx+PHP+MYSQL+Discuz 论坛

Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的，它已经在该站点运行超过两年半了。 Igor 将源代码以类 BSD 许可证的形式发布。 Nginx 已经因为它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名了。是一个高性能 Web 和反向代理服务器，它超越 Apache 的高性能和稳定性 .

Nginx + PHP + MySQL   可以承受高并发连接数，相当于同等环境下 Apache 的 10 倍（呵呵 ~~ 这可是专家说的哦。。。）。

本章将介绍 Nginx + PHP + MYSQL+ PHPMyadmin+ Discuz_X2 搭建 :LNMP+BBS

系统 :Centos 5.6

准备工具 :
libiconv-1.13.1.1.tar.gz
libmcrypt-2.5.8.tar.gz
mhash-0.9.9.9.tar.gz
mcrypt-2.6.8.tar.gz
mysql-5.1.58.tar.gz
php-5.2.14.tar.bz2
nginx-1.0.0.tar.gz
phpMyAdmin-3.0.0-rc1-all-languages.tar
Discuz_X2_SC_UTF8

安装步骤
一、 编译安装PHP5.2.14 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 ../../

# 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

PS: 我把上面的做成如下脚本： ln.sh

#!/bin/bash

# chmod +x ln.sh

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

二、编译安装MySQL 5.1.58

# /usr/sbin/groupadd mysql
# /usr/sbin/useradd -g mysql mysql
创建 mysql 用户和组 , 我这在装 MYSQL 时已经自动建了 ! 提示用户存在 !

解压 MYSQL, 配置

# tar zxvf mysql-5.1.58.tar.gz

# cd mysql-5.1.58

#./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=innobase

# make;make insatll

添加权限
# chmod +w /usr/local/mysql
# chown -R mysql:mysql /usr/local/mysql
# cd ../

三、编译安装PHP

# tar jxvf php-5.2.14.tar.bz2

# zip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1

进入 PHP 目录 . 指定编译选项安装

cd php-5.2.14/
./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-freetype-dir --with-jpeg-dir --with-png-dir --with-iconv-dir=/usr/local --with-zlib --with-libxml-dir=/usr --enable-xml --with-curl --with-curlwrappers --enable-sqlite-utf8 --with-pdo-mysql=/usr/local/mysql --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --with-openssl --enable-pcntl --enable-fpm --with-fpm-user=www --with-fpm-group=ww --enable-mbstring --with-gd --enable-gd-native-ttf --enable-sockets --with-xmlrpc --enable-zip --enable-soap --disable-debug --enable-safe-mode --with-mcrypt --with-mhash

编译安装
# make ZEND_EXTRA_LIBS='-liconv'
# make install

复制配置文件 php.ini-dist 到指定位置
# cp php.ini-dist/usr/local/php/etc/php.ini

四、修改php-fpm 配置文件

重新建个编辑

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

输入以下内容：

/usr/local/php/logs/php-fpm.pid
/usr/local/php/logs/php-fpm.log
notice
10
1m
5s
yes

default
127.0.0.1:9000

-1


0666


/usr/sbin/sendmail -t -i

127.0.0.1

$HOSTNAME
/usr/local/bin:/usr/bin:/bin
/tmp
/tmp
/tmp
$OSTYPE
$MACHTYPE
2

保存退出！

五、创建www 用户和组

# useradd www

六、安装Nginx

# cd

# tar zxvf nginx-1.0.0.tar.gz

# cd nginx-1.0.0

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

# make;make install

七、修改fastcgi.conf 文件

重命名 fcgi.conf, 手动创建

# cd /usr/local/nginx/conf/

# mv fastcgi.conf fastcgi.conf.bak

# vi fsatcgi.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;
保存退出！！！

八、编辑Nginx 配置文件

# cd /usr/local/nginx/conf/

# mv nginx.conf nginx.conf.bak

# vi nginx.conf

输入以下内容 ( 自己根据实际需要修改 )

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 51200;
events

{

use epoll;

worker_connections 51200;

}

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  sky.com;

  index index.html index.htm index.php;

  root  /usr/local/web/;

  #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 fastcgi.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/webserver/logs/access.log  access;

    }

}

九、创建日至目录, 并赋予权限

# chown -R www:www /usr/local/nginx/logs/

创建站点目录

# mkdir /usr/local/www

十、配置开机自动启动Nginx + PHP

# vi /etc/rc.local

在末尾增加以下内容：
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx

十一、平滑启动nginx

# /usr/local/nginx/sbin/nginx

十二、安装phpmyadmin

# tar zxvf phpMyAdmin-3.0.0-rc1-all-languages.tar.gz

# mv phpMyAdmin-3.0.0-rc1-all-languages /usr/local/www/phpmyadmin

修改配置文件

# cd /usr/local/www/phpmyadmin

# vi libraries/config.default.php

/**

* MySQL hostname or IP address

*

* @global string $cfg['Servers'][$i]['host']

*/

$cfg['Servers'][$i]['host'] = '127.0.0.1';

大概在 95 行！！修改成上面样子！！

测试网页可以打开 PHPmyadmin

PS: phpmyadmin 这里只是简单介绍下 ！！

十三、将Discuz 论坛程序传到站点上

# mv Discuz_X2_SC_UTF8 /usr/local/www/ds

给站点赋予权限

# chmod 777 -R /usr/local/www/ds

我们先创建一个数据库：

# mysql –uroot –p

mysql> create database bbs;

Query OK, 1 row affected (0.00 sec)

接下来再创建一个 远程登陆用户并授权 ：

mysql> grant all privileges on ds.* to zjqiu@'172.28.12.49' identified by 'zjqiu';

下面就开始安装 Discuz ：

在地址栏输入： http://IP/ds/upload

PS: 上图中当前状态一定要全部是可写状态！！在安装前一定要设置可写权限。

到了这步点下一步后就会开始安装 Discuz 了，安装完成后会直接跳转到 BBS 站点中！！

好了 ,一个简单的Discuz 论坛就这样搭好了 , Nginux 配置较简单但功能是很强的！
