Hi,

I am configuring a server with some libraries (along with other stuffs). For the libraries to be loaded automatically on a reboot, I create a config file and put it in

which contains the location of my libraries (for example /usr/local/lib64).

My servers are Redhat 6.5 64 bit. I expect the libraries in the /usr/local/lib64 to be loaded automatically on a reboot. This seems to work on some servers but not on others. On those server that it did not work, if I issue ldconfig manually after the server reboot (as root), they get loaded.

Why is it not loading on some servers? Which service or setting, loads libraries from directories specified in all the conf files in the /etc/ld.so.conf.d?

Please let me know if you need any more information from my servers?

Thanks

just drop a bash script calling them and or setting variables in /etc/profile.d

that is what this folder is for

The "that is what it's for" argument can be used in a lot of situations. Does not mean it's the right way. /etc/profile.d/ contents get parsed each time a shell sources /etc/profile (regardless of it being an interactive non-login or non-interactive shell) so that's not an efficient option unless the OP juggles with /usr/local/lib64 contents on say an hourly basis.


Note 6.6 is current.


That means you must issue the 'ldconfig' command as root on reboot.


If you don't then it doesn't update the cache.


It's not a service unless you make it one ;-p
Sane options are calling 'ldconfig' from a "@reboot" in /etc/crontab or from /etc/rc.d/rc.local. Using the latter ensures all automount points and services are available first, so if you meant to have these libraries loaded for use by services on startup you best check and reload the cache on shutdown or reload instantly using an inotify-based service like 'incron'.

Hi John,

I am with unspawn - profile.d is not the right place for this in my view. I have already implemented the rc.local solution. I just wanted to confirm whether there is any better method for this. Thanks both of you for your time.

Thanks
