Solve the database backup problem of cashier system

I have written about how to back up the data of the crash system before, but I always feel a little less. I will write down my experience this time. Generally speaking, I will always be afraid and rusty to this thing if I do not operate it once. According to my previous practice, I can reinstall the system if I can't, but I can't uninstall it and do it all over again, but now I find that I can't do it like this. This is very unprofessional behavior. If you want to be professional, you must have professional skills and literacy. Now when you encounter problems, first find the cause, and then according to the original solution of the problem, try to avoid installing the system easily.

Before doing anything, you are not sure to do a good backup, mastering the backup skills is for you to hold the door of the desire to survive. It means you have countless lives. Especially in the information age, data is very important and valuable, service will certainly become the mainstream topic in the next 5-10 years, and develop to the extreme, so the demand for professionalism is getting higher and higher in the future. especially the personal accomplishment and upbringing. No matter what we do, we all provide services on the basis of equality and mutual benefit. We have to treat our clients like guests, like VIPs, our own character and attitude are very important. In today's society, when all conditions are the same, the comparison is service. Service is not a cost-effective or cheap product. Service is a kind of humanized thing. It injects emotion, love, patience, and a sense of responsibility and mission. We treat our guests like our families. The environment we create is the environment of home. Now we have to remove the fence and remove the estrangement. Modern civilized society makes people's social circle narrower and narrower, which is not what we want to see, this is not advocated by modern civilization and the progress of the times, we need to share and share more. This is the era of progress rather than retrogression, our current high-rise buildings are promoting the formation of all this, and we have to pay a higher price to eliminate this physical gap. This is what our generation needs to do, and this is the mission of our generation-service.

Let's get to the point:

Switching the cash register requires preparation.

1. USB flash drive

3. Stop the web service, update service and MySQL service of the crash system.

4. Create a new folder in disk D, such as "2017-Civil Aviation Store backup system data".

5. Start copying data

6. Keep a copy on the flash drive for backup

7. Uninstall the windows system, and then delete the HLL directory under the HLL directory under the C disk.

8. Delete the system disk and uninstall the dirty files

9. Restart the computer

10. Delete what can't be deleted again.

11. Install the crash-pull system

12. Register the crash-pull system

Check to see if there is any previous data

14. Shut down the Lara system, then disable the web service, update service and MySQL service, and then copy the three backed up folders data, MySql and home directories to the directory where the Lara system is installed to completely replace the previous directory.

Restart the computer and find that you need to register again

16. After the registration is completed, open the crash-la system, then check the cashier system on June 30, find that you can find it, and find a previously ordered order, and then print it over, so that the cutting process of the whole crash-la system is complete
