nginx自动添加www 在 server 里面 加上 rewriteserver { if ( $host != 'www.xxxx.com' ) { rewrite "^/(.*)$" http://www.xxxx.com/$1 permanent; } }

Nginx配置多个域名 在Nginx配置目录下，创建一个vhost目录。我的配置目录在/etc/nginxmkdir /etc/nginx/vhost创建网站a的配置文件vi /etc/nginx/vhost/vhost_a.confserver配置server { listen 80; server_name www.a.com; root /var/www/html/a; index index.html index.htm index.php; location / { try_files $uri $uri/ /index.php; } error_page 500 502 503 504 /50x.html; location = /50x.html{ root /usr/share/nginx/html; } location ~ .*\.php(\/.*)*$ { fastcgi_split_path_info ^(.+?.php)(/.*)$; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } 同样创建网站b的配置文件,server_name和root改成对应的即可；然后编辑nginx.conf文件。vi /etc/nginx/nginx.conf在http里加入以下内容，再重启Nginx.http { ... include /etc/nginx/vhost/vhost_*.conf; }
