# Edit the frps.toml configuration file, add the following lines
vim frps.toml

bindPort = 7000
auth.token = "sunhaoyang"
webServer.addr = "0.0.0.0"
webServer.port = 7500
webServer.user = "admin"
webServer.password = "admin_password"

Here’s a breakdown of the server parameters:

  • bindPort = 7000: This is the port the server listens on (7000), and the client connects to the server through this port.

  • auth.token = “sunhaoyang”: This sets an authentication token. The client and server use this token to authenticate each other—like a key,only matching tokens can establish a connection.

  • webServer.addr = “0.0.0.0”: The web server listens on all network interfaces, making it accessible from anywhere.

  • webServer.port = 7500: This is the port for the web server (7500), which is used to access the FRP management interface.

  • webServer.user = “admin” and webServer.password = “admin_password”: These are the username and password for the web server, required for logging into the management interface.

  1. The bindPort=serverPort must be allowed in the settings of firewall. (E.g. ufw allow xxx/ firewall-cmd –permanent –add-port=xxx)
  2. Some vendor/providers may filter the ports and the hardware firewall may block the nonstandard port.
  3. systemctl enable frps.service/frpc.service may be failed.
    Please sudo setenforce 0 change the selinux mode from enforce to permissive, and then systemctl restart frps.service/frpc.service again.
  4. Selinux context should be set as bin_t

    sudo restorecon -v /usr/local/bin/frp/frpc
  5. Increase the interval between two failed restart processes and avoid to stop trying becasue of the frequent reboots.
