thx for your help
Maybe the option "skip-innodb" was uncommented on configuration file my.cnf. If that's the case, comment the line again. If you don't want to use INNODB, you must modify your tables to use another table format, as MyISAM p.e.

My disk still has a lot of space, so it's not the memory problem.

Recently My production server was corrupted due to maintenance shutdown by digital ocean. When we trying to recover our database we couldn't access our droplet. Somehow we managed to recover these (ibdata1, ib_logfile0, ib_logfile1 and some .frm) files. When i copied this files to my new mysql server(in another machine), I could't start the mysql server. I got this output
sudo service mysql restart
mysql stop/waiting

I checked the log file and i got this error,

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 346701 K $
Hope that's ok; if not, decrease some variables in the equation.

Please help me to resolve this.
Thanks in advance.
Note lines in the error log:
InnoDB: Error: log file ./ib_logfile0 is of different size 0 50331648 bytes
InnoDB: than specified in the .cnf file 0 5242880 bytes!
The actual size of the redo log file differs from the size in MySQL config.
Add this line to my.cnf
innodb_log_file_size= 50331648
If the tablespace is corrupted you'll still have to heal it. But at least MySQL won't stop at this step.
Hi all I have ubuntu installed on my server with apache2 and mysql; every now and then I get this message:
Warning: mysql_connect(): [2002] Connection refused
(trying to connect via unix:///var/run/mysqld/mysqld.sock) in /var/www/fanta-trade/wp-includes/wp-db.php on line 1142
Warning: mysql_connect(): Connection refused in /var/www/fanta-trade/wp-includes/wp-db.php on line 1142`
I do not think is a script error because if I restart apache it starts working again. How can I solve it?
I add also the mysql log:

Any explanation for this?
Error arises because of your memory allocation limit. It can be referred to as an Out of memory exception. It can arise again in case of high memory usage.
As you can see, the InnoDB buffer pool size is set to 128MB.
Change your buffer pool size to avoid the error again;
add this to your my.cnf
innodb_buffer_pool_size=1G
restart your mysql to make it effect
