Note to self, and everyone else:
Make sure you type disabled instead of disable when you give up and instead decides to disable selinux!
cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=TAKE_A_CLOSE_LOOK_AT_THIS_VALUE
A typo in the SELINUX value will cause a kernel panic.
I have three(3) posts in the StackExchange that quickly explain the root cause
ROOT CAUSE
- You have 37 columns in
mysql.user. That's OK for MySQL 5.0
- You are running MySQL 5.5. You are supposed to have 42 columns.
SUGGESTION
You will have to run MySQL command
# mysql_upgrade --upgrade-system-tables
Keep in mind that you are leaping two versions of MySQL. Backup the mysql.user table before doing so
UPDATE 2015-02-10 10:59 EST
Based on your comment, I can only suggest one thing: Refer to my post Any known issues upgrading from MySQL 5.1.73 to 5.6.21? under the section "ISSUE #1 : Upgrade Path" on how to upgrade two versions of MySQL.
UPDATE 2015-02-11 12:26 EST
Here is your situation
- You have a
mysql.user that is MySQL 5.0 compliant
- You have to get
mysql.user upgraded to work with MySQL 5.5
I have a crazy idea: Add the missing 5 columns by hand
In my DBA StackExchange post Cannot GRANT privileges as root, I display all the columns in the mysql.user table from MySQL 5.6, 5.5, 5.1, 5.0 and 4.x.
From those displays, we will do the following:
- Make a backup of mysql.user beforehand as mysql.user_backup
- Construct
mysql.user to have the same columns as MySQL 5.5, adding the five(5) missing colunms.
- Make sure the columns are in the same order
- Fill in the missing privs for root users with
Y
- Deploy new privs
Steps to repair mysql.user
CREATE TABLE mysql.user_backup LIKE mysql.user;
INSERT INTO mysql.user_backup SELECT * FROM mysql.user;
ALTER TABLE mysql.user
ADD Event_priv enum('N','Y') DEFAULT 'N' AFTER Create_user_priv;
ALTER TABLE mysql.user
ADD Trigger_priv enum('N','Y') DEFAULT 'N' AFTER Event_priv;
ALTER TABLE mysql.user
ADD Create_tablespace_priv enum('N','Y') DEFAULT 'N' AFTER Trigger_priv;
ALTER TABLE mysql.user
ADD plugin CHAR(64) DEFAULT NULL AFTER max_user_connections;
ALTER TABLE mysql.user
ADD authentication_string text DEFAULT 'N' AFTER plugin;
UPDATE mysql.user SET
Event_priv='Y',
Trigger_priv='Y',
Create_tablespace_priv ='Y'
WHERE user='root' and host='localhost';
FLUSH PRIVILEGES;
If you want to revert it, you can do this
RENAME TABLE mysql.user TO mysql.user_old,mysql.user_backup TO mysql.user;
FLUSH PRIVILEGES;
GIVE IT A TRY !!!
