1.安装操作系统
附:CentOS 6.3下载地址
32位:http://mirror.centos.org/centos/6.3/isos/i386/CentOS-6.3-i386-bin-DVD1to2.torrent
64位:http://mirror.centos.org/centos/6.3/isos/x86_64/CentOS-6.3-x86_64-bin-DVD1to2.torrent
说明:
1、CentOS 6.3系统镜像有两个,安装系统只用到第一个镜像即CentOS-6.3-i386-bin-DVD1.iso(32位)或者CentOS-6.3-x86_64-bin-DVD1.iso(64位),第二个镜像是系统自带软件安装包
2、安装CentOS 6.3系统的计算机内存必须等于或者大于628M(最小内存628M),才能启用图形安装模式
3、CentOS 6.3文本安装模式不支持自定义分区,建议使用图形安装模式安装
4、CentOS 6.3的系统安装方式分为:图形安装模式和文本安装模式
5、CentOS 6.3的系统运行方式分为:带图形界面、可以用鼠标操作的图形化方式和不带图形界面、直接用命令行操作的文本方式(具体的系统运行方式,可以在系统安装的过程中自定义选择)
2.升级操作系统
安装完毕后,按照实际网络环境配置IP 网关 DNS等,确认可以正常访问公网后,命令行执行yum -y update升级操作系统。
1.安装nginx第三方更新源
根据操作系统从上面下载正确的release rpm包,将rpm上传到服务器,使用root用户命令行终端执行rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm (根据实际安装包名称修改rpm名)
2.安装nginx
使用root用户登录服务器,在命令行终端执行yum -y install nginx
3.配置nginx
配置/etc/nginx/nginx.conf(此处可配置优化参数)
参考如下:

配置/etc/nginx/conf.d/default.conf
参考如下:
server {
listen 80;
server_name test.com ;
root /usr/share/nginx/html;
index index.html index.php;
# autoindex on;
access_log off;
#以下为nginx rewrite策略
location / {
if ( $args ~ “mosConfig_[a-zA-Z_]{1,21}(=|%3d)” ) {
set $args “”;
rewrite ^.*$ http://$host/index.php last;
return 403;}
if ( $args ~ “base64_encode.*(.*)”) {
set $args “”;
rewrite ^.*$ http://$host/index.php last;
return 403;}
if ( $args ~ “(<|%3C).*script.*(>|%3E)”) {
set $args “”;
rewrite ^.*$ http://$host/index.php last;
return 403;}
if ( $args ~ “GLOBALS(=|[|%[0-9A-Z]{0,2})”) {
set $args “”;
rewrite ^.*$ http://$host/index.php last;
return 403;}
if ( $args ~ “_REQUEST(=|[|%[0-9A-Z]{0,2})”) {
set $args “”;
rewrite ^.*$ http://$host/index.php last;
return 403;}
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=$1 last;
break;}
}
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;

}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#

#}

#以下为nginx php处理策略
location ~ .php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
}
#以下为提高访问速度缓存机制

}
# deny access to .htaccess files, if Apache’s document root
# concurs with nginx’s one
#
location ~ /.ht {

}
}
1.安装第三方更新源
使用root登录服务器后,在命令行终端执行yum -y install yum-priorities升级yum
然后执行以下命令加载第三方源
rpm -Uvh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-7.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
(注意以上文件均为centos 6 对应版本,其他版本操作系统可访问相应网站自行查找)
2.安装php
yum –enablerepo=remi install php php-fpm php-cli php-pdo php-mysql php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear php-devel
注意本方法安装的php为官方最新稳定版本
3.安装php加速模块memcache和eaccelerator
yum –enablerepo=remi install php-pecl-memcache php-eaccelerator
4.配置PHP
php配置文件默认为/etc/php.ini php-fpm.conf以及/etc/php.d和/etc/php-fpm.d目录下的所有文件
正常情况下无需更改默认配置
只更改/etc/php-fpm.d/www.conf内的以下字段即可
user = nginx
group = nginx
1.安装mysql
使用root登录服务器后,在命令行终端执行 yum -y install mysql mysql-server
在nginx网站root目录 默认为/usr/share/nginx/html
在该目录下使用命令行终端执行vi index.php
然后按键盘i键 输入以下内容:
<?php
session_start();
$_SESSION['time'] =date(“Y:m:d:H:s”,time());
echo “time”.”<font color=red>”.$_SESSION['time'].”</font>”.”<br>”;
echo “realserver ip address”.”<font color=red>”.$_SERVER['SERVER_ADDR'].”</font>”.”<br>”;
echo “local address”.”<font color=red>”.$_SERVER['SERVER_NAME'].”</font>”.”<br>”;
echo “SESSIONNAME”.”<font color=red>”.session_name().”</font>”.”<br>”;
echo “SESSIONID”.”<font color=red>”.session_id().”</font>”.”<br>”;
phpinfo();
?>
然后按键盘:wq保存退出
使用浏览器访问网站,如果可以正常显示当前session信息和phpinfo信息,说明正常。
如果提示404等无法访问页面或者访问页面不存在、以及直接显示源代码表示php异常,请确认nginx配置中的root参数目录路径是否正确。
