在CentOS 7中安裝軟件

在CentOS安裝以后蜻懦，執(zhí)行ifconfig發(fā)現(xiàn)命令找不到姨夹，需要安裝

[root@localhost ~]# ifconfig
-bash: ifconfig: command not found

首先設(shè)置yum源纤垂，設(shè)置為阿里的鏡像，這樣速度會快很多

備份磷账，防止更改失敗

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

從阿里的鏡像峭沦，下載新的CentOS-Base.repo

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 
-bash: wget: command not found

發(fā)現(xiàn)wget并沒有安裝，需要先安裝wget逃糟，成功

[root@localhost yum.repos.d]# yum install wget

安裝結(jié)束后再次重試下載新的CentOS-Base.repo

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

使用yum安裝ifconfig
首先對ifconfig進(jìn)行查找

[root@localhost yum.repos.d]# yum search ifconfig

net-tools.x86_64 : Basic networking tools

發(fā)現(xiàn)它在net-tools.x86_64這個包里面吼鱼，直接使用yum安裝，安裝后再試試ifconfig已經(jīng)能夠運行绰咽。
