Step 1: get the mysql YUM source

Go to the mysql official website to get the download address of the RPM package.

Https://dev.mysql.com/downloads/repo/yum/

Right-click the copy link address https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

Get the address of the rpm packet

Step 2: download and install the mysql source

Download the mysql source installation package first

[root@localhost ~] # wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

-bash: wget: command not found

Let's install wget first.

Yum-y install wget

Then execute wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

Install the mysql source

Yum-y localinstall mysql57-community-release-el7-11.noarch.rpm

Step 3: install Mysql online

Yum-y install mysql-community-server

There are more things to download. You have to wait a little while.

Step 4: start the Mysql service

Systemctl start mysqld

Step 5: set boot up

Systemctl enable mysqldsystemctl daemon-reload

Step 6: change the root local login password

After the mysql installation is complete, a temporary default password is generated for root in the / var/log/mysqld.log file.

Vi / var/log/mysqld.log

The password here is: xtqh0Neteu=7

Mysql-u root-pEnter password:

Enter a temporary password to enter the mysql command line

ALTER USER 'root'@'localhost' IDENTIFIED BY' LCode1996.'

Change the password to LCode1996. (note mysql5.7 default password policy requires that the password must be a combination of uppercase and lowercase alphanumeric special letters, at least 8 digits.)

Step 7: set up to allow remote login

Mysql does not allow remote login by default. We need to set it up, and the firewall opens port 3306.

Mysql > GRANT ALL PRIVILEGES ON *. * TO 'root'@'%' IDENTIFIED BY' LCode1996.' WITH GRANT OPTION;Query OK, 0 rows affected, 1 warning (0.05 sec) mysql > exit;Bye

Quit.

[root@localhost] # firewall-cmd-- zone=public-- add-port=3306/tcp-- permanentsuccess [root@localhost ~] # firewall-cmd-- reloadsuccess [root@localhost ~] #

Open port 3306

Step 8: configure the default encoding to UTF-8

Modify the / etc/my.cnf configuration file and add the encoding configuration under [mysqld], as follows:

[mysqld] character_set_server=utf8init_connect='SET NAMES utf8' [root@localhost ~] # vi / etc/my.cnf

Restart mysql service after editing and saving: systemctl restart mysqld

Check the code below:

Mysql > show variables like'% character%'

Step 9: test

We use the local sqlyog to remotely connect the mysql in the virtual machine.

At this point, the Mysql installation and configuration is complete
