# 新腾讯云

感谢yzh学长的资瓷，我们双十一在腾讯云购入了一台性能不错的服务器.

## 连接服务器

安全起见，不在这里记录服务器的IP地址，问群里要. 服务器不允许使用密码登录，必须用密钥登录. 需要密钥可以在内群里联系组长要.

### 连接方法

#### Linux/WSL连接方法

将密钥放到\~/.ssh文件夹下. 接下来配置**ssh config**: 修改 \~/.ssh/config，添加

```
Host {服务器昵称}
    HostName {服务器IP地址}
    User {服务器用户名}
    Port {ssh端口}
    IdentityFile {密钥路径}
```

修改后，只需要

```bash
ssh {服务器昵称}
```

即可连接. 昵称还支持**tab自动补全**!

#### VS Code 远程连接

同上，将密钥放到指定位置，配置ssh config即可.

## 环境/软件

配置了常用的环境.

### apt

**运行apt-get upgrade前慎重考虑!** 升级一些软件可能会把软件停掉，比如升级docker可能会把正在运行的docker关掉. 升级前谨慎考虑.

### docker

已经配置了USTC的docker hub镜像源. apt里的docker版本太老，使用官网的docker-ce版本.

### mysql

不要修改、删除数据库. 可以添加数据库、添加用户. 使用apt的5.7.x版本.

### java

openjdk的java 11.

### nodejs

apt里的nodejs, npm版本都太老，使用官网的版本.

### python2/3

python命令是python2.

| 命令      | 是啥             |
| ------- | -------------- |
| python  | python 2.x     |
| python3 | python 3.x     |
| pip     | python 2.x的pip |
| pip3    | python 3.x的pip |
