今天做了一个nginx的多虚拟主机的实验，遇到了一些问题。首先介绍一下配置文件如何修改。如下是我的主配置文件nginx.conf

user nobodynobody;

worker_processes2;

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

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

worker_rlimit_nofile51200;

events

{

use epoll;

worker_connections 6000;

}

http

{

include /usr/local/nginx/conf/vhosts/*.conf;

include mime.types;

default_type application/octet-stream;

server_names_hash_bucket_size 3526;

server_names_hash_max_size 4096;

log_format combined_realip '$remote_addr$http_x_forwarded_for [$time_local]'

'$host "$request_uri" $status'

'"$http_referer""$http_user_agent"';

sendfile on;

tcp_nopush on;

keepalive_timeout 30;

client_header_timeout 3m;

client_body_timeout 3m;

send_timeout 3m;

connection_pool_size 256;

client_header_buffer_size 1k;

large_client_header_buffers 8 4k;

request_pool_size 4k;

output_buffers 4 32k;

postpone_output 1460;

client_max_body_size 10m;

client_body_buffer_size 256k;

client_body_temp_path/usr/local/nginx/client_body_temp;

proxy_temp_path/usr/local/nginx/proxy_temp;

fastcgi_temp_path/usr/local/nginx/fastcgi_temp;

fastcgi_intercept_errors on;

tcp_nodelay on;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 8k;

gzip_comp_level 5;

gzip_http_version 1.1;

gzip_types text/plainapplication/x-javascript text/css text/htm application/xml;

}

在主配置文件中不放server段的信息。然后在主配置文件添加一行include/usr/local/nginx/conf/vhosts/*.conf;这样，我们就可以在 conf/vhosts目录下创建虚拟主机配置文件了。我所添加的路径是灵活的，根据本机不同的情况进行修改。

我创建了三个虚拟主机配置文件分别为123.conf,456.conf,789.conf。

123.conf如下：

server

{

listen 80;

server_name www.123.com;

index index.html index.htm index.php;

root /var/123;

location ~ \.php$ {

include fastcgi_params;

fastcgi_pass unix:/tmp/php-fcgi.sock;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME/var/123$fastcgi_script_name;

}

}

456.conf如下：

server

{

listen 80 default_server;

server_name www.456.com www.456.wangdi.com;

index index.html index.htm index.php;

root /usr/local/nginx/html;

location ~ \.php$ {

include fastcgi_params;

fastcgi_pass unix:/tmp/php-fcgi.sock;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME/usr/local/nginx/html$fastcgi_script_name;

}

}

789.conf

server

{

listen 80 ;

server_name www.789.com;

index index.html index.htm index.php;

root /var/789;

location ~ \.php$ {

include fastcgi_params;

fastcgi_pass unix:/tmp/php-fcgi.sock;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME/var/789$fastcgi_script_name;

}

}

由于我是在本地测试，所以在本地的/etc/hosts中添加域名(这里我添加了多个IP，其实单个IP也是可以的，因为域名已经区分了要访问的不同主机)

主机上也增加了IP地址

在配置文件的所在路径创建index.php文件，例如：

<?php

echo "this is 789";

?>

重启nginx和php-fpm

service nginxrestart；service php-fpm restart

然后访问这三个虚拟主机就可以了。
