 +====== Install MySQL On Slackware ======
  
 +== INSTALL MySQL ==
 +
 +Install MySQL from the official Slackware discs or using [slackpkg].
 +
 +
 +== CONFIGURE MySQL ==
 +
 +1) Create the needed database(s) and set their permissions properly. As root, run:
 +
 +     mysql_install_db --user=mysql
 +
 +User specified by ''--user'' will own database files, so it's important to set right user here, otherwise MySQL won't be able to write to database. By default MySQL in Slackware runs as user "mysql", so it's safe choice.   
 +
 +2) Enable execution of rc script to start MySQL automatically on boot:
 +
 +     chmod 755 /etc/rc.d/rc.mysqld
 +
 +3) Enable networking if needed
 +
 +Networking is disabled by default to improve security. If you want to allow network connections, comment out this line in /etc/rc.d/rc.mysql
 +     #SKIP="--skip-networking"
 + 
 +4) Start mysqld:
 +
 +     /etc/rc.d/rc.mysqld start
 +
 +//NOW YOU HAVE A CHOICE - MANUAL INSTALL OR AUTOMATIC//
 +
 +AUTOMATIC:
 +
 +5) 6) 7) Run the following, answer the questions:
 +
 +     /usr/bin/mysql_secure_installation
 +          Initial root password is "" so, just hit <ENTER>
 +
 +MANUAL:
 +
 +5) Set a password for MySQL's root password:
 +
 +     mysqladmin -u root password 'new-password-here'
 +
 +
 +6) You can connect to your MySQL server with:
 +     mysql -u root -p
 +
 +
 +7) For security reasons you should delete an empty user for localhost server
 +
 +     mysql> use mysql
 +     mysql> SELECT user, host FROM user;
 +     mysql> DELETE FROM user WHERE host='localhost' AND user='';
 +
 +== TROUBLESHOOTING ==
 +1) Server start errors can be seen in the error log that is located by default at ''/usr/lib/mysql/<hostname>.err''. Another option is to run the server directly and direct the output to the console:
 +  
 +  /usr/bin/mysqld_safe --console
 +  
 +2 Resetting the root password can be done by creating a new cnf file and add the following lines (please change the password in this example):
 +  
 +  UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
 +  FLUSH PRIVILEGES;
 +
 +Save this file (any name would do) and start the server with the --init-file argument:
 +  
 +  /usr/bin/mysqld_safe --defaults-file="new_cnf_file.cnf"
 +
