一台服务器的nginx上如果需要运营多个网站，或者把二级域名拆分成不同的web映射目录。就需要使用vhost。web client上请求不同的域名，nginx会根据vhost里的server conf加载不同的配置。
conf/nginx.conf
不需要server标签，只要在http标签的最后加上一个include
（conf文件是在conf/vhost/里面，但是这里不是写conf/vhost/*.conf，踩坑了。）
worker_processes 1;
error_log logs/error.log error;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘
‘$status $body_bytes_sent "$http_referer" ‘
‘"$http_user_agent" "$http_x_forwarded_for"‘;
#access_log logs/access.log main;
sendfile on;
include vhost/*.conf;
}
conf/vhost/jab.com.conf
server {
listen 80;
server_name www.jab.com jab.com;
root /data/jab.com/;
#charset koi8-r;
access_log logs/jab.com.log main;
location / {
root /data/jab.com/;
index index.php index.html;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
