Install libevent for CentOS RHEL OEL

Default way install library will put everything into /usr/local.

To keep it more Redhat looks:

1.First remove the old library to avoid any conflict:

yum erase libevent*

2.Download and uncompress the package:

wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar xzvf libevent-2.0.21-stable.tar.gz

3.Compile and install into /usr/lib:

cd libevent-2.0.21-stable
make clean
./configure --prefix=/usr
make
make install

You should have it under /usr/lib, with correct /usr/lib/pkgconfig. Not changes LD_LIBRARY_PATH needed at all!

4.If unhappy with where it installed, uninstall anytime:

cd libevent-2.0.21-stable
make uninstall
