nginx配置多个server监听80端口根据域名转发端口服务

https://blog.csdn.net/lovequanquqn/article/details/104562914?utm_medium=distribute.pc_relevant.none-task-blog-2~default~baidujs_title~default-0.fixedcolumn&spm=1001.2101.3001.4242.1

一、背景目标
一台服务器上面有多个服务，不同的服务有不同的端口，因为端口不好记住，所以决定配置根据域名来访问，实现不同域名转发到不到端口服务。需要用到nginx的端口转发功能。实现的目标截图如下：

PS:截图中有两个域名，missbe.cn对应端口一服务，doc.missbe.cn对应端口二服务；

二、nginx配置安装
PS:安装nginx可以通过yum install -y nginx实现；

nginx.conf配置文件如下：
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/

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;

# Settings for a TLS enabled server.
#
# server {
# listen 443 ssl http2 default_server;
# listen [::]:443 ssl http2 default_server;
# server_name _;
# root /usr/share/nginx/html;
#
# ssl_certificate "/etc/pki/nginx/server.crt";
# ssl_certificate_key "/etc/pki/nginx/private/server.key";
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 10m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }

}

PS:include /etc/nginx/conf.d/*.conf;很重要，会加载conf.d目录下的配置文件，并且这个文件里面没有server配置，都移动到conf.d目录下了；配置文件路径如下：

服务一server配置
server {
listen 80;
server_name missbe.cn;
root /usr/share/nginx/html;

location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://missbe.cn:8090;
}

error_page 404 /404.html;
location = /40x.html {
}

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

服务二server配置
server {
listen 80;
server_name doc.missbe.cn;
root /usr/share/nginx/html;

# Load configuration files for the default server block.

location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://missbe.cn:8088;
}

error_page 404 /404.html;
location = /40x.html {
}

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

PS:两个服务都监听了80端口，对应不同server_name，根据域名转发到不同的端口;
