I've just compiled the version MySQL 8.0.12 in a Ubuntu 16.0.4.
After following the instructions in the website and making the following my.cnf file:
[mysqld]
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
port=3306
log-error=/usr/local/mysql/data/localhost.localdomain.err
user=mysql
secure_file_priv=/usr/local/mysql/mysql-files
local_infile=OFF
log_error = /var/log/mysql/error.log
# Remove case sensitive in table names
lower_case_table_names=1
I get the following error:
2018-08-11T19:45:06.461585Z 1 [ERROR] [MY-011087] [Server] Different lower_case_table_names settings for server ('1') and data dictionary ('0').
What should I change so that data dictionary is aligned to server settings?
So far, I can get it to work with a workaround (I originally posted on askubuntu): by re-initializing MySQL with the new value for lower_case_table_names
after its installation. The following steps apply to a new installation. If you have already data in a database, export it first to import it back later:
sudo apt-get update
sudo apt-get install mysql-server -y
sudo service mysql stop
sudo rm -rf /var/lib/mysql
sudo mkdir /var/lib/mysql
sudo chown mysql:mysql /var/lib/mysql
sudo chmod 700 /var/lib/mysql
lower_case_table_names = 1
to the [mysqld]
section in /etc/mysql/mysql.conf.d/mysqld.cnf
.--lower_case_table_names=1
:
sudo mysqld --defaults-file=/etc/mysql/my.cnf --initialize --lower_case_table_names=1 --user=mysql --console
sudo service mysql start
root
:
sudo grep 'temporary password' /var/log/mysql/error.log
root
either by:
sudo mysql -u root -p
and executing:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPa$$w0rd';
afterwards, OR by calling the "hardening" script anyway:
sudo mysql_secure_installation
After that, you can verify the lower_case_table_names
setting by entering the MySQL shell:
sudo mysql -u root -p
and executing:
SHOW VARIABLES LIKE 'lower_case_%';
Expected output:
+------------------------+-------+
| Variable_name | Value |
+------------------------+-------+
| lower_case_file_system | OFF |
| lower_case_table_names | 1 |
+------------------------+-------+
