Yum Install MariaDB/MySQL disaster but fixed

So this should be an easy install of MariaDB/MySQL. I do not think this was a Maria issue but just an overall bug. Here is what happened and how I fixed it.

yum install mariadb-server
Then I added the rest to have what you see below.

[root@Fedora64 log]# rpm -qa | grep maria
mariadb-5.5.31-1.fc17.x86_64
mariadb-server-5.5.31-1.fc17.x86_64
mariadb-libs-5.5.31-1.fc17.x86_64
mariadb-devel-5.5.31-1.fc17.x86_64



I thought it was odd that I did not get a /etc/init.d/mysql file but I went with it, I wanted to see what happened.

[root@Fedora64 log]# mysqld_safe

Wow... The first run and a failure is not a good sign. This is a fresh install mysql directory should have been installed. So I started with --skip-grant-tables so I could get into the box and look around.

OK so it started... and does run but still a MAJOR problem still no MYSQL table !

[root@Fedora64 /]# mysql_upgrade
Phase 1/3: Fixing table and database names
Phase 2/3: Checking and upgrading tables
Processing databases
information_schema
Phase 3/3: Running 'mysql_fix_privilege_tables'...
ERROR 1049 (42000): Unknown database 'mysql'
FATAL ERROR: Upgrade failed



This can still be fixed....

OK now it has a mysql table I should be able to upgrade it

[root@Fedora64 /]# mysql_upgrade

OK
[root@Fedora64 /]#


OK So I stopped mysqld and started it without --skip-grants after all it just installed it and I have not yet set a password.

[root@Fedora64 mysql]# mysqld_safe
[root@Fedora64 /]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)



Ok so let me try that again...

[root@Fedora64 mysql]# mysqld_safe --skip-grant-tables

MariaDB [mysql]> show tables;
+---------------------------+

+---------------------------+
24 rows in set (0.01 sec)

MariaDB [mysql]> select * from user;
Empty set (0.00 sec)

MariaDB [(none)]>  create user root ;



I cannot use the following command because --skip-grant-tables in enabled.
create user root identified by '';

 So now I have a root user only by name because it has zero privileges.

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
+--------------------+
1 row in set (0.00 sec)



So I have to go into the box again with --skip-grant-tables enabled and update the root account

 UPDATE user
SET Select_priv = 'Y',
  Insert_priv='Y',
           Update_priv='Y',
           Delete_priv='Y',
           Create_priv='Y',
             Drop_priv='Y',
           Reload_priv='Y',
         Shutdown_priv='Y',
          Process_priv='Y',
             File_priv='Y',
            Grant_priv='Y',
       References_priv='Y',
            Index_priv='Y',
            Alter_priv='Y',
          Show_db_priv='Y',
            Super_priv='Y',
 Create_tmp_table_priv='Y',
      Lock_tables_priv='Y',
          Execute_priv='Y',
       Repl_slave_priv='Y',
      Repl_client_priv='Y',
      Create_view_priv='Y',
        Show_view_priv='Y',
   Create_routine_priv='Y',
    Alter_routine_priv='Y',
      Create_user_priv='Y',
            Event_priv='Y',
          Trigger_priv='Y',
Create_tablespace_priv='Y'
WHERE user = 'root';


Now a restart without --skip-grant-tables enabled and I am in as root!

WHEW. This is more of an example of how to fix it when things go wrong but I still wanted the /etc/init.d/mysql file
