Cloudera CDH/CDP 및 Hadoop EcoSystem, Semantic IoT등의 개발/운영 기술을 정리합니다. gooper@gooper.com로 문의 주세요.

0. 참고 URL을 이용하여 작업을 했는데 5.1->5.5->10.1로 진행하려 했으나 따라 했더니 5.1에서 10.1.18로 바로 진행되었다.
1. mariadb 5.1에서 바로 10.0으로 바로 upgrade가 되지 않는다. 그래서 5.1 to 5.5로 upgrade후에 10.1로 upgrade해야 한다.
2. db백업및 conf파일 백업
가. [root@so-db1 /usr/bin]$ mysqldump -p --all-databases > /tmp/backup.sql
나. [root@so-db1 /usr/bin]$ cp /etc/my.cnf /etc/my.cnf.bak
3. mysql 중지
[root@so-db1 /usr/bin]$ service mysqld stop
mysqld 를 정지 중: [ OK ]
4. data 디렉토리 백업
[root@so-db1 /usr/bin]$ cp -R /var/lib/mysql /tmp/mysql_backup
5. MariaDB 5.5 Repository설정(/etc/yum.repos.d밑에 생성하고 https://downloads.mariadb.org/mariadb/repositories/ 를 참고하여 생성한다)
vi /etc/yum.repos.d/MariaDB55.repo
# MariaDB 5.5 CentOS repository list - created 2016-11-01 02:31 UTC
