How to enable multi-site support and Nginx rewrite rule configuration in WordPress
在wordpress3.0及以上版本可以直接使用多站点,它可以:
1、只安装一个wordpress程序即可创建多个wordpress站点,可以是子域名也可以是子目录。
2、可以有独立的博客后台,独立的博客地址。
3、管理员可设置开放哪些主题给站点使用。
4、管理员可配置插件给每个站点使用。
5、多个站点之间共用“用户数据库表”,也就是表 wp_usermeta 和 wp_users,其他的为独立数据库表。
wordpress多站点的配置方法:
1、首先,备份网站的数据库,以防出现意外时恢复(一般可忽略)。
2、打开wordpress的根目录下的wp-config.php文件,在
require_once(abspath . 'wp-settings.php');
前面加上以下代码:
define('wp_allow_multisite',true);
3、进入wordpress后台,”工具”-> 点击”配置网络”
ps:如果您要使用二级域名的形式,可以到“设置”->“常规”里面,把站点地址(url)的www.去掉。
4、点击安装后,按照提示做好相关的配置
5、配置好,再次进入后台,在头部将出现“我的站点”->“管理网络”的选项菜单,接下来您可以管理或者创建站点,也可以开启主题或者插件给其他站点使用。
6、如果要给站点绑定其他域名,可以安装 wordpress mu domain mapping 插件。
nginx多站点rewrite(重写)规则
wordpress多站点模式可以被应用在多种方式上。其中最常用的是在”子目录”模式或者”二级域名”模式上。
nginx提供了两种特殊的指令:”x-accel-redirect”和”map”,使用这两个指令可以使得wordpress多站点的网络服务实现伪静态功能。
wordpress多站点使用子目录重写规则:
配置中jb51.net修改为自己的站点域名。
map $uri $blogname{ ~^(?p<blogpath>/[^/]+/)files/(.*) $blogpath ; } map $blogname $blogid{ default -999; #ref: http://wordpress.org/extend/plugins/nginx-helper/ #include /var/www/wordpress/wp-content/plugins/nginx-helper/map.conf ; } server { server_name jb51.net ; root /var/www/jb51.net/htdocs; index index.php; #多站点配置 location ~ ^(/[^/]+/)?files/(.+) { try_files /wp-content/blogs.dir/$blogid/files/$2 /wp-includes/ms-files.php?file=$2 ; access_log off; log_not_found off; expires max; } #avoid php readfile() location ^~ /blogs.dir { internal; alias /var/www/jb51.net/htdocs/wp-content/blogs.dir ; access_log off; log_not_found off; expires max; } if (!-e $request_filename) { rewrite /wp-admin$ $scheme://$host$uri/ permanent; rewrite ^(/[^/]+)?(/wp-.*) $2 last; rewrite ^(/[^/]+)?(/.*\.php) $2 last; } location / { try_files $uri $uri/ /index.php?$args ; } location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_pass php; } #此处可以继续添加伪静态规则 }
wordpress多站二级域名重写规则:
配置中jb51.net修改为自己的站点域名。
map $http_host $blogid { default -999; #ref: http://wordpress.org/extend/plugins/nginx-helper/ #include /var/www/wordpress/wp-content/plugins/nginx-helper/map.conf ; } server { server_name jb51.net *.jb51.net ; root /var/www/jb51.net/htdocs; index index.php; location / { try_files $uri $uri/ /index.php?$args ; } location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_pass php; } #wpmu files location ~ ^/files/(.*)$ { try_files /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1 ; access_log off; log_not_found off; expires max; } #wpmu x-sendfile to avoid php readfile() location ^~ /blogs.dir { internal; alias /var/www/jb51.net/htdocs/wp-content/blogs.dir; access_log off; log_not_found off; expires max; } #此处可以继续添加伪静态规则 }
备注
“map”部分可以应用于小站点。大站点的多站点应用可以使用 nginx-helper wordpress插件 。
如果想进一步优化wordpress的性能可以使用nginx的fastcgi_cache,当使用fastcgi_cache配置需要在编译nginx时加上ngx_cache_purge模块以及使用wordpress的缓存插件等等

NGINX is suitable for high concurrency and low resource consumption scenarios, while Apache is suitable for scenarios that require complex configurations and functional extensions. 1.NGINX is known for handling large numbers of concurrent connections with high performance. 2. Apache is known for its stability and rich module support. When choosing, it must be decided based on specific needs.

To ensure website security through Nginx, the following steps are required: 1. Create a basic configuration, specify the SSL certificate and private key; 2. Optimize the configuration, enable HTTP/2 and OCSPStapling; 3. Debug common errors, such as certificate path and encryption suite issues; 4. Application performance optimization suggestions, such as using Let'sEncrypt and session multiplexing.

Nginx is a high-performance HTTP and reverse proxy server that is good at handling high concurrent connections. 1) Basic configuration: listen to the port and provide static file services. 2) Advanced configuration: implement reverse proxy and load balancing. 3) Debugging skills: Check the error log and test the configuration file. 4) Performance optimization: Enable Gzip compression and adjust cache policies.

Nginx cache can significantly improve website performance through the following steps: 1) Define the cache area and set the cache path; 2) Configure the cache validity period; 3) Set different cache policies according to different content; 4) Optimize cache storage and load balancing; 5) Monitor and debug cache effects. Through these methods, Nginx cache can reduce back-end server pressure, improve response speed and user experience.

Using DockerCompose can simplify the deployment and management of Nginx, and scaling through DockerSwarm or Kubernetes is a common practice. 1) Use DockerCompose to define and run Nginx containers, 2) implement cluster management and automatic scaling through DockerSwarm or Kubernetes.

The advanced configuration of Nginx can be implemented through server blocks and reverse proxy: 1. Server blocks allow multiple websites to be run in one instance, each block is configured independently. 2. The reverse proxy forwards the request to the backend server to realize load balancing and cache acceleration.

Nginx performance tuning can be achieved by adjusting the number of worker processes, connection pool size, enabling Gzip compression and HTTP/2 protocols, and using cache and load balancing. 1. Adjust the number of worker processes and connection pool size: worker_processesauto; events{worker_connections1024;}. 2. Enable Gzip compression and HTTP/2 protocol: http{gzipon;server{listen443sslhttp2;}}. 3. Use cache optimization: http{proxy_cache_path/path/to/cachelevels=1:2k
