Centos7.4最小安装使用wget下载报：-bash wget command not found

一般我们选择安装Centos的最小安装，然后我们在使用好多工具的时候就会报错！wget不会默认被安装。

解决方法：

1.【推荐使用】

[root@DB1 ~]# yum -y install wget

安装完毕即可。

2.

rpm 安装

rpm 下载源地址：http://mirrors.163.com/centos/6.2/os/x86_64/Packages/

下载wget的RPM包：http://mirrors.163.com/centos/6.2/os/x86_64/Packages/wget-1.12-1.4.el6.x86_64.rpm

rpm ivh wget-1.12-1.4.el6.x86_64.rpm 安装即可。

安装另一个SSH客户端：FileZilla。然后传到服务器上安装，这个比较费劲,所以推荐使用第一种方法进行安装！

不过如果yum包也没有安装的话，那就只能用第二种方法了！

[root@localhost /]# yum -y install wget
