CentOS /usr/local/lib system wide $LD_LIBRARY_PATH?

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?

Solution 1:

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

Solution 2:

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.
