Nginx 虚拟主机 VirtualHost 配置

增加 Nginx 虚拟主机

这里假设大家的 Nginx 服务器已经安装好, 不懂的请阅读各 Linux 发行版的官方文档或者 LNMP 的安装说明. 配置 Virtual host 步骤如下:

1. 进入 /usr/local/nginx/conf/vhost 目录, 创建虚拟主机配置文件 demo.neoease.com.conf ({域名}.conf).

2. 打开配置文件, 添加服务如下:

server {
	listen       80;
	server_name demo.neoease.com;
	index index.html index.htm index.php;
	root  /var/www/demo_neoease_com;
 
	log_format demo.neoease.com '$remote_addr - $remote_user [$time_local] $request'
	'$status $body_bytes_sent $http_referer '
	'$http_user_agent $http_x_forwarded_for';
	access_log  /var/log/demo.neoease.com.log demo.neoease.com;
}

3. 打开 Nginx 配置文件 /usr/local/nginx/conf/nginx.conf, 在 http 范围引入虚拟主机配置文件如下:

include vhost/*.conf;

4. 重启 Nginx 服务, 执行以下语句.

service nginx restart

让 Nginx 虚拟主机支持 PHP

在前面第 2 步的虚拟主机服务对应的目录加入对 PHP 的支持, 这里使用的是 FastCGI, 修改如下.

server {
	listen       80;
	server_name demo.neoease.com;
	index index.html index.htm index.php;
	root  /var/www/demo_neoease_com;
 
	location ~ .*.(php|php5)?$ {
		fastcgi_pass unix:/tmp/php-cgi.sock;
		fastcgi_index index.php;
		include fcgi.conf;
	}
 
	log_format demo.neoease.com '$remote_addr - $remote_user [$time_local] $request'
	'$status $body_bytes_sent $http_referer '
	'$http_user_agent $http_x_forwarded_for';
	access_log  /var/log/demo.neoease.com.log demo.neoease.com;
}

图片防盗链

图片作为重要的耗流量大的静态资源, 可能网站主并不希望其他网站直接引用, Nginx 可以通过 referer 来防止外站盗链图片.

server {
	listen       80;
	server_name demo.neoease.com;
	index index.html index.htm index.php;
	root  /var/www/demo_neoease_com;
 
	# 这里为图片添加为期 1 年的过期时间, 并且禁止 Google, 百度和本站之外的网站引用图片
	location ~ .*.(ico|jpg|jpeg|png|gif)$ {
		expires 1y;
		valid_referers none blocked demo.neoease.com *.google.com *.baidu.com;
		if ($invalid_referer) {
			return 404;
		}
	}
 
	log_format demo.neoease.com '$remote_addr - $remote_user [$time_local] $request'
	'$status $body_bytes_sent $http_referer '
	'$http_user_agent $http_x_forwarded_for';
	access_log  /var/log/demo.neoease.com.log demo.neoease.com;
}

WordPress 伪静态配置

如果将 WordPress 的链接结构设定为 /%postname%/, /%postname%.html 等格式时, 需要 rewrite URL, WordPress 提供 Apache 的 .htaccess 修改建议, 但没告知 Nginx 该如何修改. 我们可以将 WordPress 的虚拟主机配置修改如下:

server {
	listen       80;
	server_name demo.neoease.com;
	index index.html index.htm index.php;
	root  /var/www/demo_neoease_com;
 
	location / {
		if (-f $request_filename/index.html){
			rewrite (.*) $1/index.html break;
		}
		if (-f $request_filename/index.php){
			rewrite (.*) $1/index.php;
		}
		if (!-f $request_filename){
			rewrite (.*) /index.php;
		}
	}
	rewrite /wp-admin$ $scheme://$host$uri/ permanent;
 
	location ~ .*.(php|php5)?$ {
		fastcgi_pass unix:/tmp/php-cgi.sock;
		fastcgi_index index.php;
		include fcgi.conf;
	}
 
	log_format demo.neoease.com '$remote_addr - $remote_user [$time_local] $request'
	'$status $body_bytes_sent $http_referer '
	'$http_user_agent $http_x_forwarded_for';
	access_log  /var/log/demo.neoease.com.log demo.neoease.com;
}

LNMP 套件在提供了 WordPress 为静态配置文件 /usr/local/nginx/conf/wordpress.conf, 在虚拟主机配置的 server 范围引用如下即可.

include wordpress.conf;

如果你使用 LNMP 套件, 进入 WordPress 后台发现会出现 404 页面, wp-admin 后面缺少了斜杆 /, 请在 wordpress.conf 最后添加以下语句:

rewrite /wp-admin$ $scheme://$host$uri/ permanent;
