I upgrade mysql 5.1 to 5.6 receive an error message..
MySQL Daemon failed to start.
Solution:
Open a terminal and do the following:
# cd /var/lib/mysql/
# rm /var/lib/mysql/mysql.sock
Delete the file inside the above folder
# rm -rf *
# sudo service mysqld start
I hope the issue is resolved for you also.
Example:
[root@localhost ~]# cd /var/lib/mysql/
[root@localhost mysql]# rm /var/lib/mysql/mysql.sock
rm: remove regular empty file `/var/lib/mysql/mysql.sock'? y
[root@localhost mysql]# rm -rf *
[root@localhost mysql]# service mysqld start

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
