在 Alpine Linux 搭建 MTProto Proxy

使用的项目：seriyps/mtproto_proxy: High performance Erlang MTProto proxy that powers https://t.me/socksy_bot

# 需要安装的软件包
apk add coreutils erlang27-dev make git

# 下载代码
curl -L https://github.com/seriyps/mtproto_proxy/archive/master.tar.gz -o mtproto_proxy.tar.gz

# 解压源代码
tar -xvaf mtproto_proxy.tar.gz

mv -T mtproto_proxy-master mtproto_proxy

cd mtproto_proxy/

# 设置监听端口
PORT=443
# 设置 secret
SECRET=`head -c 16 /dev/urandom | od -A n -t x1 -w128 | sed 's/ //g'`
# 设置从 @MTProxybot 获取的 proxy tag
TAG="47b8363ed5431e0868d2bead1a55dd50"
# 设置 TLS 伪装域名
TLS_DOMAIN="s3.amazonaws.com"

# 写入配置文件
echo '

	$command stop
	eend $?
}

reload() {
	ebegin "Reloading mtproto_proxy configuration"

设置可执行权限

chmod +x /etc/init.d/epmd /etc/init.d/mtproto-proxy

启动

service epmd start && service mtproto-proxy start
