Disclaimer: the CyberPanel was designated to work on MariaDB , although MySQL and MariaDB are compatible in almost every aspect , I have personally tested on Centos 7.4 with CyberPanel 1.6 , alone with a demo wordpress site, but this is NOT guaranteed risk-free.
A proper backup is always recommended and needed.
mysql 5.6 was installed in this tutorial , but 5.5 and 5.7 should work , you just have to manually edit version number in mysql repo
alright , there is a little problem , vanilla will convert anything comes with ' within.
for command on step 1 , 12 and 13, please grab them here if you are not clear about them.
here you go:
step1: make backup of entire database
cat /etc/cyberpanel/mysqlPasswordmysqldump -u root --all-databases > /root/backup.sql
step2: stop mariadb
systemctl stop mysqld
step3: remove mariadb repo
rm -rf /etc/yum.repos.d/MariaDB.repo
step4: download mysql repo
wget -O /etc/yum.repos.d/mysql.repo https://cn.cyberpanel.net/download/repo/mysql56.repo
step5: remove yum cache
yum clean all && rm -rf /var/cache/yum
step6: remove mariadb
yum remove MariaDB-server MariaDB-client MariaDB-common -y
step7: re-install all the dependencies that removed during step6 (be aware, this is a very long command , check if it ends with "-y" if not try split it into 2 commands and intall them)
yum install MySQL-python dovecot-mysql lsphp53-mysql lsphp53-snmp lsphp54-mysql lsphp54-snmp lsphp55-mysql lsphp55-snmp lsphp56-mysql lsphp56-snmp lsphp70-snmp lsphp71-snmp net-snmp pdns-backend-mysql postfix pure-ftpd -y
step8: install mysql
yum install mysql-community-server -y
step10: start mysql
systemctl start mysqld
step11(optional):check if mysqls are running , it should be listening on 3306 and 3307
netstat -lnp|grep 330
step12: import the backed up database from step1
cat /etc/cyberpanel/mysqlPasswordmysql -u root < /root/backup.sql
cat /etc/cyberpanel/mysqlPasswordmysql_upgrade -u root
step14( NOT recommended ): remove backed up files to free some disk space
rm -rf /root/backup.sql
