Linux kernel upgrade basic tutorial

First of all, from www.kernel.org wget under the kernel file (I downloaded it to the server with Thunder first. Wget is too slow) My linux-3.19-rc4.tar.xz

1, #tar -xf linux-3.19-rc4.tar.xz

2, #mv linux-3.19-rc4 /usr/src/

3,#cd /usr/src /linux-3.19-rc4

4,#yum update

5,#yum install ncurses-devel(ps: If you have problems compiling below, you can choose this command yum groupinstall “Development Tools&rdquo ; yum install qt-devel yum install hmaccalc zlib-devel binutils-devel elfutils-libelf-devel)

6, view the current linux kernel

#uname -r

7 Accept the default settings for each new option according to the current system kernel configuration

#sh -c ‘ yes “”
