场景描述
用户在同一台服务器上部署了多个站点，需要使用不同域名的80端口来访问不同的网站
 
准备事项

主机已安装好nginx服务
站点文件已上传到主机目录
不同域名已解析到主机IP

部署步骤
1、检查/etc/nginx/nginx.conf <span style="color:red">（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）</span>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;

events {
worker_connections 1024;
}

http {
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 /var/log/nginx/access.log main;

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;

include /etc/nginx/mime.types;
default_type application/octet-stream;

# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf; #nginx站点配置文件路径

server {
listen 80 default_server; #默认监听端口
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html; #默认站点路径

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location / {
}

error_page 404 /404.html;
location = /404.html {
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}

2、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
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}

3、重启nginx服务，验证不同域名访问效果
