https://codex.wordpress.org/Nginx
LAMP(Linux + Apache + MySQL + PHP)现在是建立WordPress最流行的技术栈，但也可以使用Nginx。WordPress支持Nginx，类似WordPress.com的大型WordPress网站，就是基于Nginx的。
有很多方法实施Nginx。可以做为Aach的前置reverse-proxy（反向代理），可以同时使用Apache的特性、功能，又获得Nginx高速的优点。很多使用nginx的网站实际上都是运行着Apache，Nginx做为reverse proxy。
这篇指南主要用于独立的Nginx setup配置，Nginx代替Apache做为主服务器。请注意，Nginx并不是Apache的完全替代品。关于WordPress的部署启动，动手之前请注意这些关键点：
- Nginx没有目录级配置文件（类似Apache的.htaccess 或IIS的web.config文件)。所有的配置都在管理员处理server level时完成，所有WordPress无法修正配置。
- 当使用Nginx的时候，仿固定链接功能（Pretty Permalinks functionality）有些不同
- 因为Nginx没有.htaccess-type 能力，所以WordPress无法为你自动修正服务器配置。（不能自动产生rewrite rules）
- 如果你没有修改install, "index.php"将被添加到你的固定链接。（通过插件或者在子主题"child theme"的functions.php中添加自定义代码）
- 最后，如果你一定要使用一些.htaccess 的某些功能，技术上来说，可以通过安装htscanner PECL extension for PHP实现。 (请注意，这不是一个完美的解决方案，所以在网站上线使用之前，请对其进行充分的测试和Debug)
这篇指南并不包括安装和配置Nginx,建议你已经安装了Nginx，并了解Nginx的基本工作调试知识后再进行阅读。
通用多站点支持(Generic and Multi-Site Support)
WordPress要与Nginx一起工作，必须先配置后端php-cgi,可选择 FastCGI 或 PHP - FPM 。因为 PHP 5.3 中php-fpm已经直接安装，所以我们就用它了。
Nginx 配置已分成 5 个不同文件 ， 为了便于理解，对每个设置都已经详细注释。笔者尽量尝试做 Nginx 配置的“最佳实践”。
主启动文件(通用)
此文件就是 /etc/nginx/nginx.conf (或者 /etc/nginx/conf/nginx.conf 如用的是 Arch Linux).
# Generic startup file.
user {user} {group};
#一般等于你的CPU数。执行命令 "grep processor /proc/cpuinfo | wc -l" 可获得
worker_processes 2;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
# Keeps the logs free of messages about not being able to bind().
#daemon off;
events {
worker_connections 1024;
}
http {
# rewrite_log on;
include mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
sendfile on;
# tcp_nopush on;
keepalive_timeout 3;
# tcp_nodelay on;
# gzip on;
#php max upload limit cannot be larger than this 此参数译者设置后测试失败
client_max_body_size 13m;
index index.php index.html index.htm;
# Upstream to abstract backend connection(s) for PHP.
upstream php {
#this should match value of "listen" directive in php-fpm pool
server unix:/tmp/php-fpm.sock;
# server 127.0.0.1:9000;
}
include sites-enabled/*;
}
与标准的 nginx.conf 文件稍微有点不同，此配置遵循 Ubuntu / Debian 声明的最大弹性启动站点(enabled sites)法- - 用“sites-available”存储一个配置， 然后链接到"sites-enabled"中的配置文件 。
单站点配置（Per Site Configuration）
# Redirect everything to the main site. We use a separate server statement and NOT an if statement - see http://wiki.nginx.org/IfIsEvil
server {
server_name _;
return 302 $scheme://example.com$request_uri;
}
server {
server_name example.com;
root /var/www/example.com;
index index.php;
include global/restrictions.conf;
#附加规则可以写在这里
# 下面的文件只能包含一个
include global/wordpress.conf;
# include global/wordpress-ms-subdir.conf;
# include global/wordpress-ms-subdomain.conf;
}
将配置分成多个片段放在多个文件中，可以允许同样的逻辑复用。'global'子目录可用于添加额外功能配置（通用功能）。（基于Nginx的安装设置情况，目录可能是 /etc/nginx/conf/global/ 也可能是 /etc/nginx/global/）
全局限制文件
# Global restrictions configuration file.
# Designed to be included in any server {} block.
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
# Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
# Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
location ~ /\. {
deny all;
}
# Deny access to any files with a .php extension in the uploads directory
# Works in sub-directory installs and also in multisite network
# Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
location ~* /(?:uploads|files)/.*\.php$ {
deny all;
}
General WordPress rules
对于单个站点安装情况来说，这就是 'global/wordpress.conf'文件：
# WordPress single site rules.
# Designed to be included in any server {} block.
# Upstream to abstract backend connection(s) for php
upstream php {
server unix:/tmp/php-cgi.socket;
server 127.0.0.1:9000;
}
server {
## Your website name goes here.
server_name domain.tld;
## Your only path reference.
root /var/www/wordpress;
## This should be in your http block and if it is, it's not needed here.
index index.php;
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location / {
# This is cool because no php is touched for static content.
# include the "?$args" part so non-default permalinks doesn't break when using query string
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
#NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
include fastcgi.conf;
fastcgi_intercept_errors on;
fastcgi_pass php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}

WordPress Multisite Subdirectory rules
多网站子目录安装，对应的 'global/wordpress.conf'文件如下：
# WordPress multisite subdirectory rules.
# Designed to be included in any server {} block.
map $uri $blogname{
~^(?P/[^/]+/)files/(.*) $blogpath ;
}
map $blogname $blogid{
default -999;
#Ref: http://wordpress.org/extend/plugins/nginx-helper/
#include /var/www/wordpress/wp-content/plugins/nginx-helper/map.conf ;
}
server {
server_name example.com ;
root /var/www/example.com/htdocs;
index index.php;
location ~ ^(/[^/]+/)?files/(.+) {
try_files /wp-content/blogs.dir/$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/example.com/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;
}
#add some rules for static content expiry-headers here
}

HTTPS in Nginx
在Nginx中打开HTTPS非常简单（译者：确实简单，但是WordPress要跑正确可不容易，大家记得要保留http的入口，另外后台设置的地址记得修改）
server {
# 同时监听 IPv4 and IPv6 on 443 ，并且打开and enables HTTPS and HTTP/2 support.
# HTTP/2 is available in nginx 1.9.5 and above.
listen *:443 ssl http2;
listen [::]:443 ssl http2;
# indicate locations of SSL key files.
ssl_certificate /srv/www/ssl/ssl.crt;
ssl_certificate_key /srv/www/ssl/ssl.key;
ssl_dhparam /srv/www/master/ssl/dhparam.pem;
# indicate the server name
server_name example.com *.example.com;
# Enable HSTS. This forces SSL on clients that respect it, most modern browsers. The includeSubDomains flag is optional.
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
# Set caches, protocols, and accepted ciphers.
# This config will merit an A+ SSL Labs score as of Sept 2015.
ssl_session_cache shared:SSL:20m;
ssl_session_timeout 10m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:ECDHE-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:CAMELLIA256-SHA:CAMELLIA128-SHA256;
}
Mozilla 提供了一个非常棒的 SSL 配置生成工具。
