背景：在vscode中使用remote-ssh插件时，需要在远程服务器安装vscode-server。在无法正常访问网络时，可按以下步骤进行离线安装。

1. First get commit id
2. Download vscode server from url: https://update.code.visualstudio.com/commit:${commit_id}/server-linux-x64/stable
3. Upload the vscode-server-linux-x64.tar.gz to server
4. Unzip the downloaded vscode-server-linux-x64.tar.gz to ~/.vscode-server/bin/${commit_id} without vscode-server-linux-x64 dir
5. Create 0 file under ~/.vscode-server/bin/${commit_id}

其中commit_id与使用的vscode版本对应，可通过查看tags进行确定。

如vscode-stable-1.47.3对应的commit_id为91899dcef7b8110878ea59626991a18c8a6a1b3e

commit_id=f06011ac164ae4dc8e753a3fe7f9549844d15e35

# Download url is: https://update.code.visualstudio.com/commit:${commit_id}/server-linux-x64/stable
curl -sSL "https://update.code.visualstudio.com/commit:${commit_id}/server-linux-x64/stable" -o vscode-server-linux-x64.tar.gz

mkdir -p ~/.vscode-server/bin/${commit_id}
# assume that you upload vscode-server-linux-x64.tar.gz to /tmp dir
tar zxvf /tmp/vscode-server-linux-x64.tar.gz -C ~/.vscode-server/bin/${commit_id} --strip 1
touch ~/.vscode-server/bin/${commit_id}/0
