#Heshan||eUNLOCK|| · August 18, 2018

handler = dbConnect("mysql", "dbname="..mysqldatabase2..";host="..mysqlhost2, mysqluser2, mysqlpassword2,";unix_socket="/var/run/mysqld/mysqld.sock, "autoreconnect=1")

Yeah, your arguments are all messed up. unix_socket should be part of the second argument, the string is also formatted incorrectly.

dbConnect("mysql", "dbname="..databaseName..";host="..databaseHost..";unix_socket=/var/run/mysqld/mysqld.sock", databaseUsername, databasePassword, "autoreconnect=1")

lmao, there are a lot of thing that even I can't understand

-- Free the arrays --
for index, houses in pairs(house) do
  houses = nil
end
for index, houseDatas in pairs(houseData) do
  houseDatas = nil
end
for index, houseInts in pairs(houseInt) do
  houseInts = nil
end
for index, houseIntDatas in pairs(houseIntData) do
  houseIntDatas = nil
end

houseid = 0
created = false

Why?
When a resource is stopped it's LuaVM is destroyed too, thus, memory is freed up anyways.
Second, I recommend you to store similar values in a table, like

local MYSQL_DATA = { --// use UPPER_CASE or UPPERCASE for constants
  {
    --// Data for connection 1
  },
  {
    --// Data for connection 2
  }
}

i'm sure there are more things that I could criticize, but I'm lazy to do so.
