Installing Net::SSH2 on Cent OS

We have struggled with this too, so will share the minimum steps needed to setup Net::SSH2 lib on Cent OS:

1. Install pre-requisite libs:
   • sudo yum install libgcrypt-devel
   • sudo yum install zlib-devel
2. Download libssh2 source code from here.
3. Untar and cd to the extracted directory.
4. Execute: ./configure — This will verify availability of packages installed in step 1 and write Makefile.
5. Execute: make — This will compile the libssh2 source code.
6. Execute: sudo make install — This will install libssh2 shared libs at /usr/local/lib
7. Execute: export LD_LIBRARY_PATH=/usr/local/lib
8. Download Net::SSH2 library source code from CPAN.
9. Untar and cd to the extracted directory.
10. Execute: perl Makefile.PL gcrypt
11. Execute: make
12. Execute: sudo make install

This should be all for installing Net::SSH2 lib on Cent OS. Incase you face any issues, please leave a comment, and we will try to help.

Note: The above has been tested successfully against Cent OS 5.6 image.
