Euler system (euleros): upgrade Mysql

Eulerian system version

Linux version 4.18.0-147.5.2.1.h579.eulerosv2r10.x86_64 ([email protected]) (gcc version 7.3.0 (GCC)) #1 SMP Sat Jul 31 09:58:46 UTC 2021

ps: The current version should be based on centos 8, so when downloading the rpm package, use the package based on centos 8
Before 8.0.28 has been installed, this time I need to upgrade it to solve the vulnerability

Upgrade Mysql

Download address list: https://dev.mysql.com/downloads/mysql/

Create a mysql folder under the folder, copy the downloaded file to mysql, and extract it

mysql-community-common-8.0.30-1.el8.x86_64.rpm
mysql-community-libs-8.0.30-1.el8.x86_64.rpm
mysql-community-client-plugins-8.0.30-1.el8.x86_64.rpm
mysql-community-client-8.0.30-1.el8.x86_64.rpm
mysql-community-icu-data-files-8.0.30-1.el8.x86_64.rpm
mysql-community-server-8.0.30-1.el8.x86_64.rpm

Backup database

Upgrade will not delete the database, but to be safe, it is recommended to back it up

Close the database

mysqladmin -u root -p shutdown

Uninstall the old version

rpm -e mysql-community-server

Upgrade

Go to the mysql folder and execute

rpm -Uvh *

After startup, connect it, and after confirming the startup is successful, restart it again

systemctl restart mysqld
