linux 安装一站式服务

1.vim: 未找到命令

解决方案（分步骤操作）

1. 首先确认是否真的没有安装

which vim || echo "Vim not installed"

2. 安装 Vim（使用 yum 包管理器）

sudo yum install vim -y

如果报错:

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"


 One of the configured repositories failed (未知),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>

然后重新安装
3. 如果提示没有 sudo 权限

su -   # 切换到root用户
yum install vim -y

4. 最小化安装系统可能需要先安装 EPEL 仓库

yum install epel-release -y
yum install vim -y

5. 验证安装是否成功

vim --version

2.虚拟机网络配置好以后，直接修改一下数据源

参考文章中的第三点更换数据源（阿里或者其他）。先把这一步做了最好，不然访问下载东西都会报错，原本配置的网站国内是访问不到的。

3.wget: command not found

1.CentOS/RHEL 系列

sudo yum install wget -y

2. 验证安装

安装完成后，运行以下命令测试：

wget --version

正常输出示例：

GNU Wget 1.14 built on linux-gnu.
