MYSQL Server Crashes frequently on Amazon EC2 - Magento Website

We have client Magento site running on ec2 large instance.

My Magento MySQL on EC2 crashes continuously, around every 12 hours. This happens on the live site. The site has more than 30000 products. The crashes started after we migrated from shared hosting to ec2. The continuous crashes are related to Innodb.

Database size is around 650 MB. We migrated the data by using mysqldump command and restored it in EC2.

Server environment : Php-fpm, Nginx , Mysqld , Varnish

Server Config:

Linux 64 bit

RAM 7GB

100 GB space

When MySQL crashes, the following is written to the log file /var/log/[url removed, login to view]

121219 02:54:18 mysqld_safe Number of processes running now: 0

121219 02:54:19 mysqld_safe mysqld restarted

121219 2:54:21 [Note] Plugin 'FEDERATED' is disabled.

121219 2:54:25 InnoDB: Completed initialization of buffer pool

121219 2:54:25 InnoDB: Fatal error: cannot allocate memory for the buffer pool

121219 2:54:25 [ERROR] Plugin 'InnoDB' init function returned error.

121219 2:54:25 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.

121219 2:54:25 [Note] /usr/libexec/mysqld: Shutdown complete

121219 02:54:25 mysqld_safe mysqld from pid file /var/run/mysqld/[url removed, login to view] ended

When we check status before restart MySQL it shows the following output:

“mysqld dead but subsys locked.”

In these cases, the only thing we have to restart the server, after which MySQL can be restarted.

In these cases, the output looks like this following:

121219 04:19:32 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

121219 4:19:32 [Note] Plugin 'FEDERATED' is disabled.

I have full file and [url removed, login to view] config attached to understand more about this issue.

Any queries contact me on PMB and this requires to fix ASAP.

The problem is that mysql cannot allocate the memory that it needs for your innodb engine to operate decently. I would suggest that we utilize dedicted mysql instance which can even be medium instead of a large instan Lagi

Looks like your server doesn't have enough RAM to allocate innodb pool. Could you show the top command output?

Your problem is easily fixed. It has to do with your InnoDB and MySQL config settings, and potentially one other issue, Which i will ask in PMB. With access to server, I can resolve in less than a day. I am an exper Lagi
