frp-完整demo

1. 下载地址：https://github.com/fatedier/frp/releases

2. 解压并使用

~]# tar xf frp_0.21.0_linux_amd64.tar.gz 
~]# cd frp_0.21.0_linux_amd64
frp_0.21.0_linux_amd64]# ls
	frpc  frpc_full.ini  frpc.ini  frps  frps_full.ini  frps.ini  LICENSE

3. 配置 frps.ini

[common]
# 绑定的外网端口
bind_port = 6666   # 注意这个端口需要做NAT映射，服务端的端口
# 虚拟web主机端口,可不用配置
vhost_http_port = 6081
# 客户端认证密码
auto_token = 123456
# 服务器看板的访问端口
dashboard_port = 7500  # 通过这个端口可以看到服务的连接状态
# 服务器看板账户
dashboard_user = admin
dashboard_pwd = admin

4. 启动

]# cat /usr/local/frp/startfrp.sh 
#!/bin/bash
#
# 自启frp服务
/usr/local/frp/frps -c /usr/local/frp/frps.ini > /usr/local/frp/frps.log &
echo $! > /usr/local/frp/frps.pid

]# cat /usr/local/frp/stopfrp.sh 
#!/bin/bash
#
# 停止frp服务
PID=$(cat /usr/local/frp/frps.pid)
kill -9 $PID
rm -rf /usr/local/frp/frps.pid

5. 配置frpc.ini

]# cat /usr/local/frp/frpc.ini 
[common]
server_addr = 这里写服务端的外网地址
server_port = 666666
log_file = ./frpc.log
auto_token = 服务端的密码

[ssh_50000]
type = tcp
local_ip = 127.0.0.1
local_port = 22   # 服务端要监听的本地端口
remote_port = 50000  # 通过frp穿透服务的端口

6. 连接

]# ./frpc -c ./frpc.ini
