Recently while restarting DNS service on Cpanel VPS it shows following errors:

[root@support ~]# /etc/init.d/named start
Starting named: /usr/sbin/named: error while loading shared libraries: libdns.so.22: cannot open shared object file: No such file or directory
[FAILED]

[root@support ~]# /etc/init.d/named start
Starting named: /usr/sbin/named: error while loading shared libraries: libisc.so.11: cannot open shared object file: No such file or directory
[FAILED]

We have checked and found that the OS template [CentOS 5.3] has been update to [CentOS 5.4] due to will all the binaries of the VPS has been updated as well. For temporary work around I have copied the libdns.so and libisc.so to libdns.so.22 and libisc.so.11.

[root@support ~]# cd /usr/lib
[root@support lib]# cp libdns.so libdns.so.22
[root@support lib]# cp libisc.so libisc.so.11

After that we were able to restart named server

[root@support lib]# service named restart
Stopping named:                                            [FAILED]
Starting named:                                             [  OK  ]
[root@support lib]#

GNU Privacy Guard (GnuPG or GPG) is a GPL Licensed alternative to the PGP suite of cryptographic software and in this post I am going to explain how you can install GNUPG and GNUPG PHP extensions on your Server.

Step 1: Go to download Directory

cd /usr/local/src/

Step 2: Download Required Modules

Download GNUPG, libgpg-error and GNUPGME (Made Easy) from http://www.gnupg.org/download/ and GNUPG PHP Extension from http://pecl.php.net/get/

Step 3: Extract All the downloaded Modules

Step 4: Installation of GNUPG

Step 5: Installation of LibGPG-Error

Step 6: Installation of GPGME

Step 7: Installation GNUPG PHP Extension

Step 8: Enable PHP Extension

TROUBLESHOOTING

It happens sometime that after loading gnupg it doesn’t shows it in PHP info OR you get Message “error while loading shared libraries: libgpgme.so.11: cannot open shared object file: No such file or directory”. You can check the same using following command

The main reason for this problem is that the server doesn’t load libraries from /usr/local/lib folder. To fix this problem just add ‘/usr/local/lib‘ to /etc/ld.so.conf and run ldconfig.
