I install custom software in /usr/local/lib
. How do I set the PATH and LD_LIBRARY_PATH in CentOS 6 system-wide to use /usr/local/lib
. I realize there may be more than one way. What's the simplest and most standard way?

You can add it in /etc/bashrc
, say, at the end.
export PATH=$PATH:/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

6While this works, for a proper installation, see @Olivier S's answer below.– cslApr 21, 2016 at 12:00

2Also, OP probably wanted
$PATH
to refer to/usr/local/bin
instead of/usr/local/lib
. I agree that's not the original question, but custom software is standardly installed in/usr/local
prefix with binaries in/usr/local/bin
, libraries in/usr/local/lib
, etc.– chutzAug 22, 2017 at 8:18
You can edit the file /etc/ld.so.conf
and add your path /usr/local/lib
to it
or create a new file in /etc/ld.so.conf.d/
like /etc/ld.so.conf.d/usrlocal.conf
and put only the following line in it
/usr/local/lib
Then run ldconfig -v
as root, and you're done.

1Is this what you meant to say: "you can edit /etc/ld.so.conf and /usr/local/lib" ? Jun 26, 2018 at 20:00

1But after doing this I am getting error
/usr/lib64/python2.6/site-packages/pycurl.so: undefined symbol: CRYPTO_set_locking_callback
while using yum. What to do?– erTugRulAug 29, 2019 at 11:25
