阿里云服务器换镜像怎么弄

网站编辑2023-05-16 17:52:21394

在阿里云服务器上更换镜像源可以通过以下步骤完成：

1. 登录服务器，打开终端。

2. 执行以下命令备份原有的镜像源文件：

```

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

```

3. 执行以下命令编辑 sources.list 文件：

```

sudo nano /etc/apt/sources.list

```

4. 将原有的镜像源地址替换为新的镜像源地址，例如将默认的阿里云镜像源地址：

```

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

```

替换为清华大学镜像源地址：

```

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse

```

注意：以上镜像源地址仅供参考，具体地址可能因地区和版本而异。

5. 保存并退出编辑器，执行以下命令更新软件包列表：

```

sudo apt-get update

```

6. 执行以下命令升级软件包：

```

sudo apt-get upgrade

```

完成以上步骤后，你的阿里云服务器就已经成功更换为清华大学镜像源了。
