Hi there,

Wonder if I can get any assistance. My WordPress install suddenly is showing:

Error establishing a database connection

I've created a test file to check the connection and it returns this error:

Could not connect: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)

We're using the usual "localhost" as host. Any suggestions? I'm trying to figure it out.

With thanks,
Marc

1.) Review your MySQL logs in /var/log/mysql. If they refer to running out of memory, create a swap file and/or upgrade to a larger droplet.

2.) Restart your MySQL service with the command service mysql restart.
