本文详细介绍下，在nginx中配置虚拟主机的方法，有需要的朋友参考下，这是一篇非常不错的学习 nginx虚拟主机配置的文章。
本节内容：
Nginx虚拟主机配置
说明：配置之前先把域名解析到服务器IP地址上
站点1：bbs.jbxue.com 程序所在目录/data/jbxue/bbs
站点2：sns.jbxue.com 程序所在目录/data/jbxue/sns
chown www.www /data/jbxue/ -R #设置目录所有者，www为nginx运行账户
chmod 700 /data/jbxue/ -R #设置目录权限
nginx配置文件路径：/usr/local/nginx/conf/nginx.conf
修改之前先备份原来的配置文件cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.confbak
一、禁止nginx空主机头
vi /usr/local/nginx/conf/nginx.conf #编辑
找到server，在上面一行添加如下内容：
代码示例:
server {
listen 80 default;
server_name _;
location / {
root html;
return 404;
}
location ~ /.ht {
deny all;
}
}
设置之后，空主机头访问会直接跳转到nginx404错误页面。
二、添加nginx虚拟主机包含文件
cd /usr/local/nginx/conf/ #进入nginx安装目录
mkdir vhost #建立虚拟目录
vi /usr/local/nginx/conf/nginx.conf #编辑
找到上一步添加的代码，在最后添加如下内容：
include vhost/*.conf;
例如：
代码示例:
server {
listen 80 default;
server_name _;
location / {
root html;
return 404;
}
location ~ /.ht {
deny all;
}
}
include vhost/*.conf;
三、修改nginx连接fastcgi的方式为unix domain socket
touch /tmp/php-cgi.sock #建立php-cgi.sock文件
chown www.www /tmp/php-cgi.sock #设置文件所有者为www（必须与nginx的用户一致）
vi /usr/local/nginx/conf/nginx.conf #编辑nginx配置文件
代码示例:
fastcgi_pass 127.0.0.1:9000; 修改为
fastcgi_pass unix:/tmp/php-cgi.sock;//如果使用的是php-fpm需要修改/etc/php/fpm/php-fpm.conf listen /tmp/php-cgi.sock；
vi /usr/local/php5/etc/php-fpm.conf #编辑php-fpm配置文件
listen = 127.0.0.1:9000 修改为
listen =/tmp/php-cgi.sock;
四、修改好之后的/usr/local/nginx/conf/nginx.conf配置文件如下（建议直接使用这个修改好的文件）
代码示例:
user www www;
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
use epoll;
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 300m;
sendfile on;
tcp_nopush 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;
#keepalive_timeout 0;
keepalive_timeout 60;
tcp_nodelay on;
server_tokens off;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
server {
listen 80 default;
server_name _;
location / {
root html;
return 404;
}
location ~ /.ht {
deny all;
}
}
server
{
listen 80;
#server_name localhost;
index index.php default.php index.html index.htm default.html default.htm ;
root /data/jbxue;
location ~ .*.(php|php5)?$
{
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location /status {
stub_status on;
access_log off;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*.(js|css)?$
{
expires 12h;
}
access_log off;
}
include vhost/*.conf;
}
五、创建fcgi.conf配置文件
vi /usr/local/nginx/conf/fcgi.conf #添加：
代码示例:
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
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 $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
六、创建虚拟主机配置文件
vi /usr/local/nginx/conf/vhost/bbs.jbxue.com.conf #添加以下内存
代码示例:
server
{
listen 80;
server_name bbs.jbxue.com;
index index.php index.html index.htm default.html default.htm default.php;
root /data/jbxue/bbs;
location ~ .*.(php|php5)?$
{
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location /status {
stub_status on;
access_log off;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*.(js|css)?$
{
expires 12h;
}
access_log off;
}
vi /usr/local/nginx/conf/vhost/sns.jbxue.com.conf #添加：
代码示例:
server
{
listen 80;
server_name sns.jbxue.com;
index index.php index.html index.htm default.html default.htm default.php;
root /data/jbxue/sns;
location ~ .*.(php|php5)?$
{
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location /status {
stub_status on;
access_log off;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*.(js|css)?$
{
expires 12h;
}
access_log off;
}
七、测试
vi /data/jbxue/bbs/index.php #新建文件，添加：
代码示例:
<?php
phpinfo();
?>
:wq! #保存退出
vi /data/jbxue/sns/index.php #新建文件，添加：
代码示例:
<?php
phpinfo();
?>
:wq! #保存退出
代码示例:
/etc/rc.d/init.d/nginx restart #重启nginx
/etc/rc.d/init.d/php-fpm restart #重启php-fpm
