配置frp过程
-
下载frp工具，下载地址如下：
https://github.com/fatedier/frp/releases
这里我选择了v0.57.0
-
解压到本地路径
tar -zxvf xxxxxx.tar.gz -
配置服务器端和客户端，这里直接从官网copy过来一份：
# 1. Modify frps.toml on server A by setting the bindPort for frp clients to connect to: # frps.toml bindPort = 7000# 2. Start frps on server A: ./frps -c ./frps.toml# 3. Modify frpc.toml on server B and set the serverAddr field to the public IP address of your frps server: # frpc.toml serverAddr = "x.x.x.x" serverPort = 7000[[proxies]] name = "ssh" type = "tcp" localIP = "127.0.0.1" localPort = 22 remotePort = 6000 # Note that the localPort (listened on the client) and remotePort (exposed on the server) are used for traffic going in and out of the frp system, while the serverPort is used for communication between frps and frpc.# 4. Start frpc on server B: ./frpc -c ./frpc.toml# 5. To access server B from another machine through server A via SSH (assuming the username is test), use the following command: ssh -oPort=6000 test@x.x.x.x -
