I have this error when MySQL wants to start:

I think your error is telling you what to do

WHY????????
Problem SOLVED.
The problem was the state of SELinux.
Changing the parameter SELINUX to "permissive" instead of "enforcing" (in the file /etc/sysconfig/selinux) the service starts OK at boot time.
That's all.
Im not sure why this is but my Wordpress Site keeps crashing with the "There was an error establishing a database connection" error.
Restarting the mysql service seems to temporarily fix this problem but it inevitably crashes again and again.
I thought it may be a memory issue so I upgraded my instance from 1gb to 2gb. But nothing seems to have changed.. I'd rather not pay the massive extra cost for this if it isn't memory related.
Here is some of the mysql log file relating to the crash. All the crashes seem to contain the following:

****UPDATE****
So I have changed the size of the innodb_buffer_pool_size as mentioned below and also made a swapfile. My site still crashes every few hours and I am slowly losing the will to live.

Your buffer size is too high. It probably does not need to be that size, see this answer on dba.stackexchange.com
https://dba.stackexchange.com/questions/27328/how-large-should-be-mysql-innodb-buffer-pool-size
If you are using Amazon Linux, according to mysql docs (https://dev.mysql.com/doc/refman/5.7/en/ha-vm-aws-setup.html) the setting for this is in /etc/my.cnf
Probably altering the setting in this file to innodb_buffer_pool_size = 10M would fix your problem
The above fixes the specific problem shown in the logs above. If there is another problem being logged which concerns memory use then add a 4GiB swapfile with these commands
/bin/dd if=/dev/zero of=/swapfile bs=1M count=4096; /sbin/mkswap /swapfile; /sbin/swapon /swapfile
Using swap isn't magic it will allow your system to run slow and bloated. However, if this gets you over "blips" in memory usage, it could be good

I have the same configuration with the following link - Wordpress running on AWS EC2 micro instance with Linux AMI, so implement the answers recommended by adding swapfile. It seems not working properly still. It keeps crashing every 3 - 5 days, so I have to restart it by "sudo service mysqld restart".
Amazon EC2, mysql aborting start because InnoDB: mmap (x bytes) failed; errno 12
my configuration /etc/my.cnf looks like this:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mysqld according to the
# instructions in http://fedoraproject.org/wiki/Systemd
innodb_buffer_pool_size = 128M
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
And free -m looks like this.

I am experiencing regular MySQL server crashes (on Linux). After running
sudo /etc/init.d/mysql restart
the problem goes away, but temporary. It might be one day or couple, but the crash will happen anyway. Here's an excerpt from the error log file, after the crash and before the daemon restart. I am not sure it reflects any useful information though.

The problem did not disappear after reinstalling the server.
Perhaps it's time to install the database on clean OS install, and bring all my databases there, but before such time-consuming solution I'd like to try some less-involving ones, if there are any.
