Installing OS-programs in linux

Question

A previous user asked a question on where to install applications, and the answer spells out how the directories are used, however, as the answer says, when you use make install for a system daemon like sshd or ntpd it typically puts the results in /usr/local/sbin. The problem is that the original service is still present and running out of /usr/sbin. If you are building a new server daemon from source, how do you make it the active version? Do you overwrite/uninstall the original version? or do you leave the original as it is, and somehow point the system to your new version in /usr/local?

Answer 1

So, when you compile a new SSH version for instance manually, you need to go into your sshd_config file and set the path for it, removing the old path, in your case sbin.

A default CentOS path is this in /etc/ssh/sshd_config:

This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

So in your case, remove:

/usr/local/sbin

Then put in the config file your new path with a : to add to the path, or you can just force it to use 1 path. (You would have to put PATH=\xx\xx\xx and uncomment it to work also as the daemon reads this config file)

Alternatively, you can overwrite the original with the newer one, will have no issues with it, another point to make clear is that when you overwrite something, make a backup, obviously.
