centos - linux 卸载了软件之后 whereis firefox 还是可以看到

Question

使用的是 linux centos 7.
先使用

yum -y install firefox
yum -y install httpd

然后卸载执行了：

yum remove firefox
yum remove httpd

然后用whereis 查看，却发现还是有：

[root@localhost ~]#
[root@localhost ~]# whereis firefox
firefox: /usr/lib64/firefox
[root@localhost ~]# whereis httpd
httpd: /etc/httpd
[root@localhost ~]#

如何才可以卸载干净。

Answer 1

I tested it. When yum uninstalled httpd, it reported an error and prompted a warning. However, the execution continued successfully, but the /etc/httpd directory remained. Manual rm to delete it can be done. The same can be learned from Firefox
