nginx下主域名强制跳转到www

1、先监听 域名，然后转发到www下面

server {listen 80;server_name ;rewrite ^(.*) $scheme://www.$server_name$1 permanent;}#配置server {listen 80;root path;server_name ;location ~ \.php$ {fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}}

2、在nginx里面配置 rewrite 规则

server{listen 80;server_name ;if ($host != '') {rewrite ^/(.*)$ /$1 permanent;}
