Bug 1385196

Description of problem:
https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/paged/director-installation-and-usage/appendix-a-ssl-tls-certificate-configuration has several related issues.

Version-Release number of selected component (if applicable):
OSPD 9

How reproducible:
100% of the time

Steps to Reproduce:
1. Start with a reimaged RHEL 7.2 machine.
2. Follow the steps in https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/paged/director-installation-and-usage/chapter-4-installing-the-undercloud#sect-Configuring_the_Director
3. This installs the undercloud.  When you get to Section 4.6, go to Appendix A in order to set undercloud_service_certificate
4. Follow the steps in https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/paged/director-installation-and-usage/appendix-a-ssl-tls-certificate-configuration

5. When you get to Step A.5, this operation fails: openssl ca -config openssl.cnf -extensions v3_req -days 3650 -in server.csr.pem -out server.crt.pem -cert ca.crt.pem

Actual results:

Using configuration from openssl.cnf
Error opening CA private key /etc/pki/CA/private/cakey.pem
139637833467808:error:0200100D:system library:fopen:Permission denied:bss_file.c:398:fopen('/etc/pki/CA/private/cakey.pem','r')
139637833467808:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:400:
unable to load CA private key

Expected results:

The openssl command should succeed.

Additional info:

Note that in order to work around this, several other issues popped up.

First I ran the operation as sudo.  It looked like a file was missing, so I
put the expected file there by doing

sudo cp ca.key.pem /etc/pki/CA/private/cakey.pem

Note that the file did not have the same name as what I copied.  I am not sure if this action is correct.

Then I got:

sudo openssl ca -config openssl.cnf -extensions v3_req -days 3650 -in server.csr.pem -out server.crt.pem -cert ca.crt.pem
Using configuration from openssl.cnf
/etc/pki/CA/index.txt: No such file or directory
unable to open '/etc/pki/CA/index.txt'

So I did sudo touch /etc/pki/CA/index.txt

I then got:

sudo openssl ca -config openssl.cnf -extensions v3_req -days 3650 -in server.csr.pem -out server.crt.pem -cert ca.crt.pem
Using configuration from openssl.cnf
unable to load number from /etc/pki/CA/serial
error while loading serial number
140664789718944:error:0D066096:asn1 encoding routines:a2i_ASN1_INTEGER:short line:f_int.c:215:



So I did sudo vi /etc/pki/CA/ssudo vi /etc/pki/CA/serial
erial and put a 1 in there.



After that, things looked good:


sudo openssl ca -config openssl.cnf -extensions v3_req -days 3650 -in server.csr.pem -out server.crt.pem -cert ca.crt.pem
Using configuration from openssl.cnf
