首先  frps  和 frpc  对比

[common]
bind_addr = 0.0.0.0
#bind_port frp链接的端口  首先必须在安全组开放端口，其次，访问时 客户端要和服务端一致
bind_port = 7000
#vhost_http_port  ：是自定义的 与客户端无关  如果定义为8000，首先必须在安全组开放端口，其次，访问时 要加端口8000  ，80默认不写
vhost_http_port = 80
vhost_https_port = 443
dashboard_port = 7500
dashboard_pwd = admin

[web01]
type = http
auth_token = admin
custom_domains = www.rjgcs.xyz
 

==================================

 [common] is integral section
[common]
# A literal address or host name for IPv6 must be enclosed
# in square brackets, as in "[::1]:80", "[ipv6-host]:http" or "[ipv6-host%zone]:80"
#要和frps    ip保持一致
server_addr = 39.105.212.161
#frps的链接端口7000
server_port = 7000

# Resolve your domain names to [server_addr] so you can use http://web01.yourdomain.com to browse web01 and http://web02.yourdomain.com to browse web02
[web01]
type = http
local_ip = 127.0.0.1
local_port = 80
auth_token = admin
#通过frps 域名 + 自定义访问端口（frps配置文件中的自定义端口）穿透到frpc中对应的 web01 ，并映射到frpc   127.0.0.1 80端口 ，然后根据后缀本地跳转对应的tomcat
custom_domains = www.rjgcs.xyz

============

再看nginx
