Have a Wordpress website running on Digital Ocean. This morning began receiving "Error establishing a database connection" message. Droplet is a 2 GB Memory / 40 GB HD running Ubuntu 14.04.
Tried restarting mysql, but get "Job Failed to Start".
Status reports "mysql stopped/waiting"
Help me anyone please.
Additionally I do not know how to set up SWAP.

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.
I have installed Centos on Amazon EC2 .On Centos i installed apache and mysql too . The Mysql server goes down by giving this message

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
