I want to connect the scheduler with my already MySQL database but I don’t know how to connect it. Anyone help me! 
Hello,
scheduler does not work with the database directly, so if you use any ORM for database access all you need to do is to set up a connection of that ORM to mysql.
If you use Entity Framework, you need to install MySQL database adapter for EF nuget.org/packages/MySql.Data.Entity/ and specify it in connection string, e.g.
<connectionStrings>
<add name="MyDbContextConnectionString" providerName="MySql.Data.MySqlClient" connectionString="server=localhost;UserId=username;Password=password;database=myDatabase;CharSet=utf8;Persist Security Info=True"/>
</connectionStrings>

All the rest code can be the same as in samples with MSSQL databases
