Update Mysql (MariaDB) 5.5 para 10.1 no CentOS 7

O upgrade é simples, mas como sempre, faça um backup full de suas bases de dados com o comando abaixo.

mysqldump -u root -ppassword --all-databases > /tmp/all-database.sql

1	mysqldump -u root -ppassword --all-databases > /tmp/all-database.sql

Mesmo assim faça uma cópia do diretório das bases por via das dúvidas (o paranóico) …

systemctl stop mysql
cp -a /var/lib/mysql/ /var/lib/mysql.bak

1 2	systemctl stop mysql cp -a /var/lib/mysql/ /var/lib/mysql.bak

Crie o arquivo MariaDB10.repo com o comando abaixo

vim /etc/yum.repos.d/MariaDB10.repo

1	vim /etc/yum.repos.d/MariaDB10.repo

Copie o conteúdo abaixo e cole no novo arquivo

# MariaDB 10.1 CentOS repository list - created 2016-01-18 09:58 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

# MariaDB 10.1 CentOS repository list - created 2016-01-18 09:58 UTC

# http://mariadb.org/mariadb/repositories/

[mariadb]

name = MariaDB

baseurl = http://yum.mariadb.org/10.1/centos7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgcheck=1

Salve e saia do arquivo e agora … update no MariaDB

yum update MariaDB-server MariaDB-client

1	yum update MariaDB-server MariaDB-client

Agora inicie o banco

systemctl start mariadb

1	systemctl start mariadb

Agora rode o comando para fazer o upgrade do Mysql

mysql_upgrade

1	mysql_upgrade

Deve retornar algo conforme abaixo
