Share one of the available mysq startup scripts

In a real-world production environment, the MySQL service environment is typically deployed using a binary generic package downloaded from the official website, which allows for rapid deployment of the MySQL environment (the deployment can look at http://jim123.blog.51cto.com/4763600/1835010), But it's going to be a bit of a hassle when it starts and shuts down or restarts, and it needs to use the tools in the Bin folder under the MySQL environment path, and it doesn't add a startup script to the/etc/rc.d/init.d/. If you need to manage more than one of the different environments of MySQL restart, the efficiency of these methods will be very low, it is possible to forget the specified user error at startup, and so on, so we can add mysq in the/etc/rc.d/init.d/path launch script to implement, This allows us to quickly restart or close MySQL by using the service mysqld restart or/etc/init.d/mysqld retsart.

So that we can quickly manage the MySQL server, of course, there are many services in the actual production environment and there is no startup script, we also need to manually modify the Add startup script.
