We are a free/open source project. We have a CentOS 7 VM and it needed some software updated because the base CentOS 7 is stuck at PHP 5.4 and MediaWiki 1.26. We enabled Software Collections (SCL), which gains access to Apache 2.4, PHP 7.1 and MariaDB 10.2 (and friends).
We are having trouble with the MariaDB 5.5 to 10.2 upgrade which is needed for MediaWiki. We are following mariadb.com's Upgrading from MariaDB 5.5 to MariaDB 10.0. The sticking point is Step 6:
6. Run mysql_upgrade
Running the script results in:
# /opt/rh/rh-mariadb102/root/usr/bin/mysql_upgrade -u root -p Enter password: xxxxxxxxxxxxxxxxxxxxxx Version check failed. Got the following error when calling the 'mysql' command line client ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) FATAL ERROR: Upgrade failed
We know we have the correct password for the database because we had to recover it earlier in the process. Its a simple copy/paste into the terminal so there are no typos.
We have verified the service is enabled, and its is running:
# systemctl status rh-mariadb102-mariadb.service * rh-mariadb102-mariadb.service - MariaDB 10.2 database server Loaded: loaded (/usr/lib/systemd/system/rh-mariadb102-mariadb.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2017-12-21 14:06:26 EST; 8min ago ...
If someone could point out the problem we are having and how to fix it, we would be eternally grateful.
Thank you in advance.
This may have something to with the problem:
# ls /var/lib/mysql/ aria_log.00000001 ibdata1 ib_logfile1 mysql.sock performance_schema aria_log_control ib_logfile0 mysql my_wiki [root@ftpit ~]# mysql -u root Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 39 Server version: 10.2.8-MariaDB MariaDB Server ... MariaDB [(none)]> use my_wiki; ERROR 1049 (42000): Unknown database 'my_wiki' MariaDB [(none)]>
my.cnf tells MariaDB to use
[mysqld] section and
data=... was added after the 5.5 to 10.2 migration. The
data=... comes from mariadb.com's MariaDB Options:
# cat /etc/opt/rh/rh-mariadb102/my.cnf | grep -v '#' [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock symbolic-links=0 [mysqld] data=/var/lib/mysql [mysqld_safe] log-error=/var/log/mariadb/mariadb.log pid-file=/var/run/mariadb/mariadb.pid !includedir /etc/opt/rh/rh-mariadb102/my.cnf.d
Here are the prelude steps. They are my field notes for backtracking in case of problems. The steps consist of stopping 5.5 database, writing all data via
innodb_fast_shutdown = 0, removing the old 5.5 software, and installing the new 10.2 software.
