CentOS 6.5 installs MySQL in yum mode

First, MySQL Introduction

When it comes to databases, we mostly think of relational databases, such as MySQL, Oracle, SQL Server, and so on, which are very easy to install on Windows, and if you want to install a database on Linux, I have to recommend MySQL database first. And the first version of the MySQL database is distributed on Linux systems.

MySQL is a relational database management system developed by the Swedish MySQL AB company, currently owned by Oracle Corporation. MySQL is an associated database management system that keeps data in separate tables rather than putting all of the data in a large warehouse, which increases speed and increases flexibility. MySQL's SQL language is the most commonly used standardized language for accessing databases. MySQL software uses a dual licensing policy (this term "authorization policy"), it is divided into community and commercial version, because of its small size, speed, low total cost of ownership, especially the open source of this feature, the general small and medium-sized web site development has chosen MySQL as the site database. Thanks to the performance of its community edition, PHP and Apache make a good development environment.

To install MySQL database on Linux, we can download the MySQL database rpm package on its official website, Http://dev.mysql.com/downloads/mysql/5.6.html#downloads, Everyone can download the corresponding database files according to their operating system, the latest version is 5.6.10.

Here I am the installation of MySQL database through Yum, this way to install, can be related to MySQL some services, jar packages are installed to us, so save a lot of unnecessary trouble!!!

Second, uninstall the original MySQL

Because MySQL database is very popular on Linux, so the mainstream Linux version of the current download basically integrates the MySQL database inside, we can use the following command to see if the MySQL database is installed on our operating system

Rpm-qa | grep mysql//This command will check if the MySQL database is already installed on the operating system

If there is, we can unload it by RPM-E command or rpm-e--nodeps command.

RPM-E MySQL//normal delete mode rpm-e--nodeps MySQL//brute force Delete mode, if you use the above command to delete, prompted to have dependent other files,
The command can be used to forcefully delete the

After the deletion we can pass Rpm-qa | grep mysql command to see if MySQL has been uninstalled successfully!!

Third, the installation of MySQL through Yum

I am using yum to perform MySQL database installation, first we can enter Yum List | grep mysql command to view the downloadable version of the MySQL database available on Yum:

Yum List | grep MySQL

You can get the downloadable version of the MySQL database on the Yum server:

Then we can install the MySQL mysql-server mysql-devel by entering the Yum install-y mysql-server mysql mysql-devel command ( Note: When we installed MySQL, we did not install the MySQL client, which is equivalent to installing the MySQL database, we also need to install the Mysql-server server .

Yum install-y mysql-server MySQL Mysql-deve

After waiting for some time, Yum will help us choose the software needed to install the MySQL database and some other ancillary software.

We found that the installation of the MySQL database through the Yum method eliminates a lot of unnecessary hassle, and when the following results occur, the MySQL database installation is successful.

At this point we can view the version of the mysql-server that we just installed with the following command

Rpm-qi Mysql-server

We installed the Mysql-server is not the latest version, if you want to try the latest version, then go to the MySQL website to download rpm package installation, so that our MySQL database has been installed.
