all:
I have a software automatically running as a service on windows platform, which depends on the Mysql db service .
But when the computer restarted ,sometimes the software can't connect to mysql when the mysql
service started later than my software.
So how can I check wether mysql service is running already in my software (using c++ language)?
Got to Start, search for "Services"
Open the application
Search MySQL (if 8 then its mysql80), right click and start.
Above steps are given, considering the fact you have to manually start the service.
If you just want to check that service is running, just check status of the above.

I can connect from Azure Cloud Shell.
I can connect from local DBeaver client (Community Edition 21.2.3).
However, I cannot connect from local Command Prompt or MySQL Workbench. The response is not returned.
It seems to be hanged out. I allowed these apps to communicate via Windows Defender firewall.

What's wrong? Please help.
It looks like there is a problem with the latest MySQL 8.0.27 release. I've encountered the same issues you describe when trying to connect using the command line from different MacOS and Linux machines.
There 's also a bug reported here: https://bugs.mysql.com/bug.php?id=105288
I suggest you add your findings to it as well.
I tried a bunch of different things before simply rolling back to 8.0.26, which still works fine for me.
Is stopping MySQL Process with net stop MySQL57 safe? We are running MySQL Server on Windows Server and would like to backup whole server with file-system approach. If we would use net stop MySQL57 would it not cause any database corruption?
Using net stop and then net start is equivalent to using the services applet in the Windows control panel.
net stop also causes the service's dependent services (if any) to stop and restart. For example, IIS Admin depends on World Wide Web, NNTP, FTP and SMTP if you have those installed and running.
net stop causes the services to shutdown "properly" and re-read the Windows registry before starting again. It's the same as restarting safely. Use the service names and not the display names (which won't work anyway).
You can also use the service controller app sc as well as net start/net stop.
You can see (or should see, if it installed properly) the MySQL service in the registry along with all others under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\.
Hope that helps a bit.
I have checked almost all solutions both in Openshift forum and here in stackoverflow but couldn't solve the problem.
Here is the situation
I have a php server with load balancing in one gear.
I have a second gear for mysql server along with PhpMyAdmin. At present OpenShift does not support load balancing for PhpMyAdmin, so my second gear does not have any scaling feature.
Now I want to host a php app in first gear and the database in the second gear. So how do I connect them internally (would be better if I could do it without port forwarding)? I need all the commands from the beginning to the end unfortunately.
Thank you.
You should just add the mysql cartridge to your scaled application. It will still put the mysql database on it's own gear, but it will be accessible from your scaled application using the standard mysql environment variables. You can view those variables by sshing into your application and running env | grep mysql. If you decide to run your own second gear for the mysql database (you still had to install a web cartridge anyways to do that right?) then you will either HAVE to use port forwarding for direct access, or you will have to write an API on that server that will allow your application to access the mysql database.
I have MYSQL installed in my Windows system. If I just turn on the system and leave it at the Windows Login screen without logging in, I'm still able to access the MYSQL DB from a remote system by knowing the IP.
Is this normal? Does MYSQL begin running even before login? Or is remote login somewhat different?
It's usually a windows service, and that indeed starts before you login.
Yes, MySQL service will start when Windows started and you can connect any MySQL hosted system on the network knowing IpAddress OR System Name.

I have MySQL database which I created on university's server
I try to develop android application that can send msg from mobile through XMPP protocol to keep data at my database server(from 1.)
At this time, I already downloaded openfire 3.7.0.dmg(MAC OS X) then try to setup server on my laptop
My problem is I cannot follow Database Installation Guide the error occurred: Does not have mysqladmin command at my Terminal. So, I cannot create table for openfire. Should I need to install MySQL on my laptop ?
Moreover, I pretty much confuse with [YOUR_HOST] of this statement :
jdbc:mysql://[YOUR_HOST]/[DATABASE_NAME]
I don't know what is it? should be localhost or anything?
Anyone can help me ? Thank you so much
You need to have MySQL installed on one computer you have access to. If you want to install it on your Mac, you can either download it directly from mysql.com, or you could install it using a package manager like Homebrew.
Next, make sure your MySQL install can listen for connections over TCP; there's a troubleshooting guide for that.
Next, use the name of the machine your MySQL server is running on in place of [YOUR_HOST]. If it's running on the same machine as OpenFire, you can use localhost.
