Docker的CentOS镜像由于做了精简,去掉了 ping 命令,那我们该如何安装这个命令呢
首先可以用 yum provides 命令来搜索哪个软件包里包含了 ping 命令
- [root@a7128460b671 /]# yum provides "*/ping"

可以看到好几个软件包都包含这个命令,但 iputils 最像是我们要找的,安装它
- [root@a7128460b671 /]# yum install iputils
- .......
- [root@a7128460b671 /]# ping 114.114.114.114
- PING 114.114.114.114 (114.114.114.114) 56(84) bytes of data.

搞定^^
