Personal Notes-2
This is my second personal note. As the title suggests, this is my own personal note (personal-oriented) to record some knowledge points I encounter in daily life that need to be recorded.
All content does not provide explanations, only operations. If needed, read by yourself. The content in personal notes is generally fragmented and messy, please forgive.

Quickly Set Up socks5 with Docker
For installing Docker, you can jump to: Detailed Process and Basic Commands for Installing Docker on Linux
Alternatively:
curl -fsSL https://get.docker.com | bash -s docker
Pull and run the image
docker run -d --name socks5 --restart=unless-stopped -p <PROXY_PORT>:1080 -e PROXY_USER="<PROXY_USER>" -e PROXY_PASSWORD="<PROXY_PASSWORD>" serjs/go-socks5-proxy
<PROXY_PORT>是外部访问端口
<PROXY_USER>是连接用户名
<PROXY_PASSWORD>是连接密码 (设置长一点，推荐16位数字+混合大小写起步)
