Mysql working on the Slackware Linux

(1) Install the mysql :

slackpkg install mysql

notes: This command will install mysql program on the slackware and create "mysql" user and "mysql" group

(2) Creating the needed databases and setting their permissions

mysql_install_db --user=mysql

(3) Change the permission of the /etc/rc.d/rc.mysql file

chmod 755 /etc/rc.d/rc.mysql

(4) The mysqld is running now, you can login with "mysql" as below

mysql -u root -p

notes: -p options is necessary and the "mysql" password default is ""

(5) Delete where user="" localhost="localhost"

USE mysql;
SELECT usr, local from USER;
DELETE FROM USER WHERE host='localhost' AND user='';

(6) Chage "mysql" password as system root

/usr/bin/mysql_secure_installation

Adding the utf8_unicode_ci support

vi /etc/my.cnf

vi /etc/my.cnf
### Adding following lines to the 'mysqld' section
collation-server = utf8_unicode_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

 If you want using mysql through network, modifying /etc/rc.d/rc.mysql, comments below line

# SKIP = "--skip-networking"

 

Troubleshooting

Method 1 : Server errors are written into the /var/lib/mysql/[yourhostname].err file

Method 2 : Directly run the server and direct the output to the console

/usr/bin/mysqld_safe --console
