我要评论一、在线安装wget
使用以下命令查看是否安装过wget，如果什么不显示就说明没有安装过
rpm -qa | grep wget
以下为wget安装命令
sudo yum install -y wget
如果显示以下内容时，说明安装失败，国外镜像源封锁加强，需要更换国内镜像源后才能安装 点击更改镜像源
loading mirror speeds from cached hostfile
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>
or
subscription-manager repos --disable=<repoid>
5. configure the failing repository to be skipped, if it is unavailable.
note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). if it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
cannot find a valid baseurl for repo: base/7/x86_64
二、离线安装wget
1、进入wget[下载地址]，下载wget的rpm安装包到本地
2、将下载好的wget文件用xftp或其他上传软件将文件上传至 /opt下
3、运行安装wget包，并查询是否安装成功
rpm -ivh /opt/wget-1.14-10.el7.x86_64.rpm
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
