Help Mysql problem on vps of llinux (ubuntu 16.04)

[Ernesto]

Well I have a problem and I want to open a server but the problem is that when I put mysql (the data is well set) when I open the server it says [15:56:15] ERROR: mysql / connection.lua: 62: attempt to call global 'mysql_ping' (to nil value)
[15:56:15] ERROR: global / money_globals.lua: 26: call: failed to call 'mysql: query' [string "?"]
[15:56:15] ERROR: mysql / connection.lua: 62: attempt to call global 'mysql_ping' (to nil value)
[15:56:15] ERROR: global / money_globals.lua: 37: call: failed to call 'mysql: query' [string "?"]

and in the other server it only says: Call to non-running server resource (mysql) [string "
? "]

I really appreciate the help if someone helps me and will fulfill my dreams

Thanks for read.

You have to add the MTA MySQL module into your server.

But i have the modules.

Well you don't. The debug says that it's nil, meaning it doesn't exist. Do you have the module defined in the server config? Another way of starting the module is to use the loadmodule command, so loadmodule mta_mysql in this case.
