检查
/etc/nginx/nginx.conf
（nginx 默认配置文件路径，如果使用其他方式部署，对应部署的其他路径）配置文件，确保文件中包含
include /etc/nginx/conf.d/
.conf;
。
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

location = /404.html {
error_page 500 502 503 504 /50x.html;
location = /50x.html {
在目录 /etc/nginx/conf.d 下面新建 website1.conf，website2.conf，文件名可自定义。监听端口都改为 80 端口并绑定不同的域名，root 路径分别配置为不同的站点路径。
website1.conf 文件内容：
server {
listen 80; #website1 监听端口
server_name one.example.com; #website1 绑定域名
root /var/www/html/web1/; #website1 站点路径
# Load configuration files for the default server block.
location / {
index index.php index.html index.htm; #站点默认页面
error_page 404 /404.html;
location = /40x.html {
error_page 500 502 503 504 /50x.html;
location = /50x.html {
website2.conf 文件内容：
server {
listen 80; # website2 监听端口
server_name two.example.com; # website2 绑定域名
root /var/www/html/web2/; # website2 站点路径
# Load configuration files for the default server block.
location / {
index index.php index.html index.htm; # 站点默认页面
