linux install mysql under (rpm Installation)

Database download package:

https://www.mysql.com/downloads/

Open the original agreement in the community of open source GPL version inside Download

We use mysql community server inside

Which is the client workbench tool

MySQL Cluster is an oracle out of their own version of the cluster (it integrates a number of open source tools and value-added services)

Select the operating system and version

It recommended to install in linux

You can also select the version

Download the server package and client packages

If a server package, architecture diagram of the things that have a

Also next client utilities packet, the client packages, similar connection layer

After downloading the inside spread centos linux system with command rz

rpm is the package manager

xshell can directly drag

Rz command can also be used, if not install it: yum install lrzsz

yum is the Package Explorer, the problem can be solved package dependencies, the package needs to have downloaded

Spread linux system

Install mysql steps:

Environmental clean-up

centos7 will own a mariadb

To see if you have installed

rpm -qa |grep -i mysql

rpm -qa | grep -i mariadb (centos7 default system comes)

mariadb mysql come from, is one of its branches, need to be cleaned out

Clean out mariadb package

Yum install you directly, then use the yum source mariadb, which is not the same with mysql official version, we have to install the official version, you need to clear out mariadb, and then manually install their own official version of mysql download

rpm -e plus package name, the package cleared mariadb

Rpm can be seen with the deletion will fail, suggesting the need to install software dependencies

rpm -e mariadb-libs-5.5.56-2.el7.x86_64

When rpm deleted if there are dependencies, you can use yum remove + package name to delete mariadb

start installation:

General use software installed with yum install directly can, but there is a problem: with yum, then, is to use the default mariadb yum source to find, could not be found, so our own install

rpm -ivh + package installation packages needed

rpm -ivh MySQL-client-5.6.42-1.el7.x86_64.rpm

rpm -ivh MySQL-server-5.6.42-1.el7.x86_64.rpm

After a successful installation server some messages will appear as follows:

[root@localhost soft]# rpm -ivh MySQL-server-5.6.42-1.el7.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

You will find that password in '/root/.mysql_secret'.

You must change that password on your first connect,

no other statement but 'SET PASSWORD' will be accepted.

See the manual for the semantics of the 'password expired' flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test database.

This is strongly recommended for production servers.

See the manual for more instructions.

View the file, you can see that I generate a new random password when you reinstall mysql

ps -ef | grep -i mysql mysql process to see if there
