不像apache，nginx 通过http模块里面的server模块来配置虚拟主机的：
server {
# Replace this port with the right one for your requirements
listen 80 default_server; #could also be 1.2.3.4:80
# Multiple hostnames separated by spaces. Replace these as well.
server_name star.yourdomain.com *.yourdomain.com; # Alternately: _
root /PATH/TO/WEBROOT;
error_page 404 errors/404.html;
access_log logs/star.yourdomain.com.access.log;
index index.php index.html index.htm;
# static file 404's aren't logged and expires header is set to maximum age
location ~* \.(jpg|jpeg|gif|css|png|js|ico|html)$ {
access_log off;
expires max;
}
location ~ \.php$ {
include fastcgi_params;
fastcgi_intercept_errors on;
# By all means use a different server for the fcgi processes if you need to
fastcgi_pass 127.0.0.1:YOURFCGIPORTHERE;
}
location ~ /\.ht {
deny all;
}
}
Nginx 通过 FCGI protocol 和php-fpm(php fastcgi process manager)通信的配置：
location ~ [^/]\.php(/|$) {
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
if (!-f $document_root$fastcgi_script_name) {
return 404;
}
# Mitigate https://httpoxy.org/ vulnerabilities
fastcgi_param HTTP_PROXY "";
astcgi_param SCRIPT_FILENAME $document_root$fastcgi_file_name;
fastcgi_pass 127.0.0.1:9000; ## 如果以unix socket 形式进行通信 fastcgi_passunix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
