View version information for Centos/linux

Today, when installing MySQL, I want to choose the MySQL version of Linux.

1. View kernel version and x86/x64 version

Method One, Cat/proc/version

cat /proc/2.6. -431el6.x86_64 ([email protected]) (gcc4.4.  7201203134.4. 7-4) (GCC) #1:2013 

Method Two, Uname-a

1 uname -a22.6. -431. el6.x86_64 #1:2013 x86_64 x86_64 x86_64 gnu/linux

The kernel version of Linux shown here is the red Hat 4.4.7-4,64 bit,

2. view the Linux kernel version

The Red Hat 4.4.7-4 shown above is the version number of RET hat itself, because it is compiled from Red Hat Enterprise Linux according to the source code published under open source rules and this is not the kernel version of Linux.

We can use the LSB-REALES-A command to view the kernel version of Linux.

(1), use LSB-REALES-A command, but display:bash:lsb_release:command not found. You need to install the LSB.

1 [[email protected] desktop]# lsb_release-a2 bash:lsb_release:command not found

(2), using direct yum install-y lsb

(3), view Linux kernel version

1[Email protected] desktop]# Lsb_release-a2LSB Version:: base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-Noarch3 Distributor Id:centos4Description:centos Release6.5(Final)5Release:6.56Codename:final

At this point, we know that when choosing the MySQL version, we should use the 6.5 version &64 bit.
