* DB : Add support for MySQL 8
- Splits commands to create user and grant access on database, the old
statement is no longer supported by MySQL 8.x
- `NO_AUTO_CREATE_USER` is no longer supported by MySQL 8.x so remove
that from db.properties conn parameters
For mysql-server 8.x setup the following changes were added/tested to
make it work with CloudStack in /etc/mysql/mysql.conf.d/mysqld.cnf and
then restart the mysql-server process:
server_id = 1
sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_ENGINE_SUBSTITUTION"
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=1000
log-bin=mysql-bin
binlog-format = 'ROW'
default-authentication-plugin=mysql_native_password
Notice the last line above, this is to reset the old password based
authentication used by MySQL 5.x.
Developers can set empty password as follows:
> sudo mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED BY '';
