can you help me?
I got this error when service mysqld_multi starts on boot:

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.
total used free shared buffers cached
Mem: 996 134 861 0 2 16

I attach /var/log/mysqld.log of past few days. Appreciated to receive recommendations.

I solved the problem by setting the port of the SQLEXPRESS server to a specific value as it was dynamic and reserved port 3306.

The server 'crashes' and restarts at seemingly random intervals although it does happen around 7:30 am (+/- 30 minutes) more then other times it seems.
There are no cron jobs running anywhere near this time.
Any help would be appreciated!

Drop your ib_log files and Put innodb_force_recovery=6 in config file and restart your mysql it will resolve
Turns out that from time to time, memory usage would spike (I'm guessing that this was because of a dramatic spike in apache child processes) and this would cause memory pressure. The out-of-memory killer would choose mysql to close down, because it was (usually) the biggest memory user in the system.
So to fix, I
got more memory
fine tuned Apache to control the number of child processes that were spun up.
