  In general, the system version is higher, the more support something new. Unless there are special requirements for software, otherwise I believe we all want to kernel version is the latest. As a Linux system administrator, also a kernel upgrade basic skills. Here are what the kernel upgrade method:

System environment: CentOS 6.5 mini

1: Display system version
# Uname -r
2.6.32-431.el6.x86_64

2: update the kernel
# Yum -y install kernel

3: Reboot the system
# Reboot

4: Check whether to enable the new kernel
# Uname -r
2.6.32-504.8.1.el6.x86_64

5: You can delete the old kernel space saving
# Rpm -q kernel
kernel-2.6.32-431.el6.x86_64
kernel-2.6.32-504.8.1.el6.x86_64

# Rpm -e kernel-2.6.32-431.el6.x86_64
