Build a website

My website has gone down with an "error establishing database connection". The people who host the site have said I need to try something in the command line. Which I don't have the skills to do. The email from then said ... The most common reason why MySQL is not running is that it stopped or failed to start as a result of not enough memory. This can usually be seen by attempting to start the mysql server ("service mysql start" on Ubuntu and some other systems) and then reviewing the mysql error log (usually in /var/log/mysql/[login to view URL] or similar file path). A useful program to review the logs one page at a time is "less" –for example: less /var/log/mysql/[login to view URL] If you see memory issues such as "mmap can't allocate" then you can be sure that you are having memory issues. Potential solutions are: 1) upsize to a larger server. We recommend at least a 1GB droplet for any server utilizing a MySQL database. 2) Enable swap space, which functions in the same way as RAM, except it's slower since it's using disk space to simulate RAM. Your system uses this only in the case where you run out of RAM, and it'll likely result in slower responses from your site, but if you add enough swap (generally twice as much as the amount of RAM you have is a safe bet) it should prevent MySQL from crashing and causing your site to go down. You can find a guide relevant to your Linux distribution here: [login to view URL] 3) Optimizing MySQL with mysqltuner. On your server there is a file: /etc/mysql/[login to view URL] that sets the basic configuration settings of your MySQL service. It controls how much RAM MySQL will try to use, and in what way. The MySQLtuner utility takes a look at certain log files and other information regarding how your MySQL server is functioning and gives you a diagnosis on how efficiently it is performing. At the bottom will be a list of configuration changes you can make to your config file. The longer your server has been running before using MySQLtuner, the more accurate the information it gives you will be. ------- In short I need help getting it back up today.
