Error opening CA private key on Ubuntu

Question

I am trying to create a self-signed certificate using OpenSSL on Ubuntu 14.04. When I enter the command openssl ca -in tempreq.pem -out server_crt.pem, I get the following error:

Using configuration from /root/myCA/caconfig.cnf  
**Error opening CA private key** ~/myCA/private/cakey.pem  
139754719667872:error:02001002:system library:fopen:No such file or directory:bss_file.c:398:fopen('~/myCA/private/cakey.pem','r')  
139754719667872:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:400:  
unable to load CA private key

I have already confirmed that the command nano ~/myCA/private/cakey.pemopens the file cakey.pemand allows read permission for this file.

Any help would be appreciated. Thank!

It seems that you are running root, make sure that you did not accidentally follow the instructions in the Ubuntu.com OpenSSL article, and set the dir parameter in /root/myCA/caconfig.cnf in / home / root / myCA.

, . , /home/root/myCA, , /root/myCA.
