1. Software Environment:

CentOS 7

Mysql 5.6

2. Linux Environment installation Method comparison:

Installation method	Advantages	Disadvantages
Source Package Compilation Installation	The function module of the software can be customized;	Source code compilation optional parameters, error-prone; The compilation and installation process takes a long time; Does not have the software management function;
RPM Installation (Redhat package Manager)	Provide software management function, install, upgrade, uninstall; Easy and fast operation;	inter-package dependencies;
Yum installation (Yellow dog updater,modified)	Support Online, offline two ways; Automatic resolution of dependency relationships;

3. Yum Introduction

Before you start the installation, learn about the common commands and related configurations for Yum below.

• Uninstalling software

  Yum Remove Package_name #只删除软件包, preserving configuration files and data files;

Yum Erase Package_name #删除软件和它所有的文件.

3.2 Creating a network Yum source

To build a Yum source, you need to know the following configuration files and related directories first.

/etc/yum.conf #yum的配置文件, configuring cache path, log path, and GPG check

/etc/yum.repos.d/#自定义的仓库

/var/log/yum.log #yum日志

/var/cache/yum/#存储下载的rpm包

yum.conf configuration file, mainly divided into two parts, [main] partial configuration of global variables, the second part of the configuration of the warehouse server, which can also be stored in the/etc/yum.repos.d/directory, saved as. repo file configuration.

The following information is/etc/yum.conf content:

[Email protected] etc]# NL yum.conf 1 [main] 2 cachedir=/var/cache/yum/$basearch/$releasever 3 keepcache=0 4 debuglevel=2 5 Logfile=/var/log/yum.log 6 Exactarch=1 7 Obsoletes=1 8 Gpgcheck=1 9 Plugins=1 Teninstallonly_limit=5 bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/ Bug_report_page.php?category=yum Distroverpkg=centos-release # This is the default, if do this bigger Yum won ' t see if the metadata Newer on the remote and so you'll "gain" the bandwidth of not have to # Download the new metadata and ' pay ' for it by Yum don't have correct # information. + It is esp. important, to has correct metadata, for distributions like # Fedora which don ' t keep old packages around. If you don ' t like this checking # interupting your command line usage, it's much better to has something # Manually check the metadata once an hour (Yum-updatesd'll do). # metadata_expire=90m # PUT YOUR REPOS here OR in separate files named File.repo # IN/ETC/YUM.REPOS.D

After you have learned the above knowledge, start creating the MySQL repository file.

cd/etc/yum.repos.d/ Touch Mysql-community.repo VI Mysql-community.repo Add the following information to the file: #Enable to use MySQL 5.6 [Mysql56-community] Name=mysql 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/ Enabled=1 #0为关闭yum源, 1 to open the Yum source Gpgcheck=0 #0为不需要验证软件包, 1 is required to verify the package gpgkey=

4. Install MySQL

Simply execute the yum install MySQL and make a quick and easy command!
