ssh-key生成失败问题

Posted 2020-08-20 wkccs

在centos6.5下面：

ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/data/kris/.ssh/id_rsa):
Could not create directory ‘/data/kris/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open /data/kris/.ssh/id_rsa failed: No such file or directory.
Saving the key failed: /data/kris/.ssh/id_rsa.

 

解决办法：

yum remove selinux*

 

原因：

 searched the intertubes, and all thread responses say to check the file permissions or my $HOME environment variable. They were fine. The only odd result in the list was: http://rhn.redhat.com/errata/RHBA-2010-0013.html which includes a paragraph:

* SELinux denials caused by the ssh-keygen‘s
"system_u:object_r:initrc_exec_t" context caused ssh-keygen to fail to
generate public/private RSA key pairs. These updated SELinux policy rules
allow ssh-keygen to successfully generate public/private RSA key pairs as
expected. (BZ#538453)

The problem should have been repaired in the previous version of Red Hat according to the advisory. There was no reason SELinux should be installed on the system, but considering all the other extraneous software I‘d already removed, I figured it was.
