摘要：
server{ listen 80; server_name test.com test1.com... server{
listen 80;
server_name test.com test1.com test2.com;
# apache不支持nginx可以
index index.html index.htm index.php;
root /data/wwwroot/test.com;
if ($host != 'test.com' )
{
rewrite ^/(.*)$ http://test.com/$1 permanent;
}
}server_name后面支持写多个域名，这里要和httpd的做一个对比
permanent为永久重定向，状态码为301，如果写redirect则为302
# /usr/local/nginx/sbin/nginx -t
# /usr/local/nginx/sbin/nginx -s reload
