K mouza: Created page with "Install guestfish: <syntaxhighlight> yum install guestfish -y </syntaxhighlight> Generate an encrypted password: <syntaxhighlight> openssl passwd -1 new_password </syntaxhighlight> Use guestfish to edit /etc/shadow..."

<p>Created page with "Install guestfish: <syntaxhighlight> yum install guestfish -y </syntaxhighlight> Generate an encrypted password: <syntaxhighlight> openssl passwd -1 new_password </syntaxhighlight> Use guestfish to edit /etc/shadow..."</p>
<p><b>New page</b></p><div>Install guestfish:<br />
<br />
<syntaxhighlight><br />
yum install guestfish -y<br />
</syntaxhighlight><br />
<br />
Generate an encrypted password:<br />
<br />
<syntaxhighlight><br />
openssl passwd -1 new_password<br />
</syntaxhighlight><br />
<br />
Use guestfish to edit /etc/shadow inside the rhel-7-guest image:<br />
<br />
<syntaxhighlight><br />
guestfish -a rhel-7-server-guest-image.qcow2<br />
><fs> run<br />
><fs> list-filesystems<br />
><fs> mount /dev/sda1 /<br />
><fs> vi /etc/shadow<br />
</syntaxhighlight><br />
<br />
Replace the root encrypted password in /etc/shadow with the new one you just generated.<br />
<br />
Edit the /etc/ssh/sshd_config file and uncomment the following line:<br />
<syntaxhighlight><br />
PermitRootLogin Yes<br />
</syntaxhighlight><br />
<br />
Now you can quit guestfish<br />
<syntaxhighlight><br />
><fs> quit<br />
</syntaxhighlight><br />
<br />
You should now be able to import the the guest image into OpenStack and once deployed, login as root using the password you set above, in addition to the normal mechanism using the OpenStack key pair.</div>
