4. Create a connection

cd /usr/src
ln -sv /usr/src/linux-3.19 linux

5. Perform kernel settings

cd /usr/src/linux
make menuconfig

In this step, it is best to copy a .config file that was run previously and make modifications to this file. Otherwise, it may not be able to restart.

For example:

cp /boot/config-3.10.0-123.el7.x86_64 /usr/src/linux/.config

6. Compile the kernel

make -- it may take from 1 hour to 3 hours.

make modules_install
make install

7. Restart.
