System environment: Centos7.4

The steps to build are as follows:

1. First go to the source file directory of this machine

[root@edu-mycat-01 ~] # cd / usr/local/src/

two。 Use wget to download the rpm package of the official Yum source:

[root@edu-mycat-01 src] # wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

3. Install the RPM package

Uninstall the original package mariadb-libs first

[root@edu-mycat-01 src] # yum remove mariadb-libs-y

[root@edu-mycat-01 src] # rpm-ivh mysql57-community-release-el7-11.noarch.rpm

4. Use yum again to install mysql-serve

[root@edu-mycat-01 ~] # yum-y install mysql-community-server

Check to see if it started successfully:

[root@edu-mycat-01 ~] # ps-aux | grep mysqld

5. Set the mysqld service to boot automatically:

[root@edu-mycat-01 ~] # systemctl enable mysqld

6. Log in with the initial password

[root@edu-mycat-01 ~] # cat / var/log/mysqld.log | grep'A temporary password'

[root@edu-mycat-01] # mysql-uroot-p

Reason for error: (password is too simple)

Mysql > set global validate_password_policy=0

Mysql > set global validate_password_length=1

Mysql > set global validate_password_mixed_case_count=2

Mysql > alter user 'root'@'localhost' identified by' mysqlpasswd'

Log back in successfully and complete the installation!
