现在很多人都有用到二级域名，我介绍下Linux下lnmp（Linux+nginx+mysql+php）虚拟主机的配置：
1.首先，在你购买域名的地方，解析二级域名，比如万网：
原域名：www.test.com
二级域名1：mtest.test.com
二级域名2：ztest.test.com
(如果是本地测试,请修改host文件，Linux:/etc/hosts;)
2.配置虚拟主机：
网站根目录：/var/www
站点www.test.com 目录 /var/www/test
站点mtest.test.com 目录 /var/www/mytest
站点ztest.test.com 目录 /var/www/ztest
设置目录所有者 www是nginx用户
chown www.www /var/www/ -R
设置目录权限
chmod 777 -R /var/www
修改nginx连接fastcgi方式为unix domain socket
建立php-cgi.sock文件
touch /tmp/php-cgi.sock
设置文件所有者与nginx运行用户一致
chown www.www /tmp/php-cgi.sock
编辑nginx.conf文件
修改 fastcgi_pass 127.0.0.1:9000; 为 fastcgi_pass unix /tmp/php-cgi.sock
编辑php-fpm配置文件
修改：listen = 127.0.0.1:9000; 为 listen = /tmp/php-cgi.sock
添加虚拟主机目录文件
进入/usr/local/nginx/conf 目录下
执行命令 mkdir vhost
在nginx.conf http部分末尾添加
include vhost/*.conf
nginx配置文件参考如下：
user www www;
worker_processes 1;
error_log /var/www/wwwlogs/nginx_error.log crit;
pid /usr/local/nginx/logs/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;
multi_accept on;
}
http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
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 256k;
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;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
#limit_conn_zone $binary_remote_addr zone=perip:10m;
##If enable limit_conn_zone,add "limit_conn perip 10;" to server section.
server_tokens off;
#log format
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
include vhost/*.conf;
}
在/usr/local/nginx/conf目录下添加(fcgi.conf):
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$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;
添加虚拟主机配置文件(在vhost目录下添加文件,命名随意，最好是以网站名称命名方便维护修改)：
mtest.test.com配置文件：
server
{
listen 80;
#listen [::]:80;
server_name mtest.test.com;
index index.html index.htm index.php default.html default.htm default.php;
root /var/www/mtest;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
#error_page 404 /404.html;
location ~ .*\.(php|php5)?$ {
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
access_log /var/www/wwwlogs/mtest.test.com.log access;
}
添加ztest.test.com配置文件：
server
{
listen 80;
#listen [::]:80;
server_name ztest.test.com;
index index.html index.htm index.php default.html default.htm default.php;
root /var/www/ztest;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
#error_page 404 /404.html;
location ~ .*\.(php|php5)?$ {
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
access_log /var/www/wwwlogs/ztest.test.com.log access;
}
