WordPress nginx环境下开启多站点

在wp-config.php插入

define('WP_ALLOW_MULTISITE', true);

进入管理页面安装网络，子目录模式
按提示再在wp-config.php插入

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'www.domain.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

安装插件Nginx Helper,启用Nginx Map

会生成类似/home/wwwroot/www.domain.com/wp-content/uploads/nginx-helper/map.conf的配置文件

本人使用军的的LNMP1.2，将添加vhost时自动生成的www.domain.com.conf修改为如下

# Upstream to abstract backend connection(s) for php
upstream php {
        server unix:/tmp/php-cgi.sock;
        server 127.0.0.1:9000;
}
map $http_host $blogid {
    default               0;
    include /home/wwwroot/www.domain.com/wp-content/uploads/nginx-helper/map.conf;
}
server {
    server_name www.domain.com;
    root /home/wwwroot/www.domain.com;

    index index.php;
