Recently, I want to build Mysql environment locally. The preparation and installation process is as follows:

1. Software environment:

CentOS 7

Mysql 5.6

2. Linux environment installation method comparison:

Advantages and disadvantages of installation source package compilation and installation can be customized software function module;

Source compilation optional parameters, error-prone;

The compilation and installation process takes a long time;

Does not have software management functions;

RPM Installation (Redhat Package Manager)

Provide software management functions, installation, upgrade, uninstall;

Easy and fast operation;

(b) Private dependence;

Yellow Dog Updater,Modified

Support online and offline two ways;

automatically resolve dependencies;

3. Yum Introduction

Before starting the installation, let's understand the common commands and related configurations of yum.

3.1 Yum common command

Query software installation

yum list installed #Query installed software

yum list installed| grep package #Query whether a specific software is installed

install software

yum install packageName #Install packages online

yum localinstall packageName.rpm #localinstall

update software

yum list updates #List software that can be updated

yum update package_name #Update software

uninstall software

yum remove package_name #Remove only packages, keep configuration files and data files;

yum erase package_name #Delete the software and all its files.

3.2 Create a network yum source

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

/etc/yum.conf #yum configuration file, configuration cache path, log path and gpg check

/etc/yum.repos.d/ #custom repository

The requested URL/var/log/yum.log was not found on this server.

/var/cache/yum/ #Store downloaded rpm packages

yum.conf configuration file, mainly divided into two parts,[main] part to configure global variables; the second part, used to configure the repository server, this part can also be in/etc/yum.repos.d/directory, save as.repo file for configuration.

The following information is contained in/etc/yum.conf:

[root@Durian 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

10installonly_limit=5

11bugtracker_url=http://bugs.centos.org/set_project.php? project_id=23&ref=http://bugs.centos.org/bug_report_page.php? category=yum

12distroverpkg=centos-release

13# This is the default, if you make this bigger yum won't see if the metadata

14# is newer on the remote and so you'll "gain" the bandwidth of not having to

15# download the new metadata and "pay" for it by yum not having correct

16# information.

17# It is esp. important, to have correct metadata, for distributions like

18# Fedora which don't keep old packages around. If you don't like this checking

19# interupting your command line usage, it's much better to have something

20# manually check the metadata once an hour (yum-updatesd will do this).

21# metadata_expire=90m

22# PUT YOUR REPOS HERE OR IN separate files named file.repo

23# in /etc/yum.repos.d

After understanding the above knowledge, start to create Mysql repository files.

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 turns off the yum source, 1 turns on the yum source

gpgcheck=0 #0 for packages that do not require validation, 1 for packages that require validation

gpgkey=

4. install MySQL

With the repository configured and yum commands known, you can install it!

Simple execution yum install mysql, easy to get a command!

You can use Mysql now!

After installation, check the files under the cache directory/var/cache/yum to see the rpm package of get.
