Installation of MySQL-5.7.19 under CentOs6.5 system

It has not been updated for a long time. Today, I would like to share with you a wave of simple documents. The beginner spirit of a rookie is to keep learning and seek help from God!

Today, I would like to recommend a blog address: http://sumongodb.blog.51cto.com/.

Okay! Cut the crap and get to work!

The mysql5.7.19 binary installation under CentOs6.5 is the official source package compiled by myself.

First, let's install some dependency packages:

Yum-y groupinstall "Development tools" yum-y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make

Extract the mysql binary installation package:

Tar-zxvf mysql-5.7.19.tar.gz-C / usr/local/mysql
