1、必要条件

安装 code-server 需要一台可以运行code-server的服务器。可以使用自己拥有的物理机器，也可以使用云服务器。至少需要2核CPU和1 GB内存，可以使用任何Linux发行版，环境必须启用websocket，因为code-server使用websocket在浏览器和服务器之间通信。

2、通过官方脚本安装

安装code-server最简单的方法是使用官方提供针对Linux、macOS和FreeBSD的安装脚本。如可能，install脚本尝试使用系统包管理器。

1）显示安装命令但不进行安装

[root@localhost ~]# curl -fsSL https://code-server.dev/install.sh | sh -s -- --dry-run
CentOS Linux 7 (Core)
Installing v4.19.0 of the amd64 rpm package from GitHub.
mkdir -p ~/.cache/code-server
curl -#fL -o ~/.cache/code-server/code-server-4.19.0-amd64.rpm.incomplete -C - https://github.com/coder/code-server/releases/download/v4.19.0/code-server-4.19.0-amd64.rpm
mv ~/.cache/code-server/code-server-4.19.0-amd64.rpm.incomplete ~/.cache/code-server/code-server-4.19.0-amd64.rpm
rpm -U ~/.cache/code-server/code-server-4.19.0-amd64.rpm
rpm package has been installed.
To have systemd start code-server now and restart on boot:
sudo systemctl enable --now code-server@$USER
Or, if you don't want/need a background service you can run:
code-server

2）执行安装

curl -fsSL https://code-server.dev/install.sh | sh

命令说明:

注意：安装 使用脚本安装时，可能遇到 "curl: (7) Failed connect to raw.githubusercontent.com:443; 拒绝连接" 的错误，此时可以尝试设置 http 代理来解决，命令如下：

export https_proxy=http://192.168.31.31:8118

参考文档 ：https://coder.com/docs/code-server/latest/install 

3、通过程序文件安装 

如不能使用上面脚本方式安装，可以尝试下载编译好的二进制程序文件进行安装，命令如下： 

下载地址：https://github.com/coder/code-server/releases/download/v3.4.1/code-server-3.4.1-linux-amd64.tar.gz 

若要区分使用的程序文件，取决于操作系统和CPU的架构。CentOS 7上推荐使用code-server-3.4.1版本，如想使用较新的版本，可以尝试使用近几年CentOS Stream 、Rocky Linux、AlmaLinux或 Ubuntu 发布的新版本的Linux。 

1）查看系统

cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

2）下载程序文件并解压

wget https://github.com/cdr/code-server/releases/download/3.4.1/code-server-3.4.1-linux-x86_64.tar.gz
tar -xvzf code-server-3.4.1-linux-x86_64.tar.gz

3）查看帮助信息

cd code-server-3.4.1-linux-x86_64
./code-server --help
***** Please use the script in bin/code-server instead!
***** This script will soon be removed!
***** See the release notes at https://github.com/cdr/code-server/releases/tag/v3.4.0
info  Wrote default config file to ~/.config/code-server/config.yaml

注意：

如在CentOS 7 上安装较新版本的 coder-server，glibc版本会有问题，可能提示如下信息：

node: /lib64/libm.so.6: version GLIBC_2.27' not found (required by node) node: /lib64/libc.so.6: version GLIBC_2.25' not found (required by node)
node: /lib64/libc.so.6: version GLIBC_2.28' not found (required by node) node: /lib64/libstdc++.so.6: version CXXABI_1.3.9' not found (required by node)
node: /lib64/libstdc++.so.6: version GLIBCXX_3.4.20' not found (required by node) node: /lib64/libstdc++.so.6: version GLIBCXX_3.4.21' not found (required by node)

解决最好的办法，安装使用新版本的Linux。

4）启动 code-server

./code-server --bind-addr 0.0.0.0:8080
***** Please use the script in bin/code-server instead!
***** This script will soon be removed!
***** See the release notes at https://github.com/cdr/code-server/releases/tag/v3.4.0
info  Using config file ~/.config/code-server/config.yaml
info  Using user-data-dir ~/.local/share/code-server
info  code-server 3.4.1 48f7c2724827e526eeaa6c2c151c520f48a61259
info  HTTP server listening on http://0.0.0.0:8080
info      - Using password from ~/.config/code-server/config.yaml
info      - To disable use `--auth none`
info    - Not serving HTTPS

在浏览器上即可访问了。初次访问，需要输入登录密码，密码可以在~/.config/code-server/config.yaml中找到。

ssh会话断开，code-server就会退出，后台运行程序可以参考下面的文档。
