This article mainly tells you about the actual operation process of MySQL database permission settings. We all know that MySQL database permissions are generated with the development of MySQL Databases and are gradually paid attention, the following articles describe how to set MySQL database permissions.
Add the user's permission to access the MySQL database

security standards that everyone must comply with. If the system administrator establishes his/her own security rules on this basis, the security is enhanced. Management helps to strengthen user awareness and make users clear that information is a valuable asset. The system administrator should make the security protection method as simple as possible for users and provide some security improvement tools. The network administrator must establish a reasonable amount of user pain, which is a func

waste of time, but if your team is very small, sometimes you don't have to write an editor for a one-time task in order to save a few hours.Custom Editor: Sometimes we write a very bad in-game editor to do graphics or levels, I mean without optimization, I am afraid that only we will do so.R.U.B.E: For our next game, we have developed an in-game editor almost ourselves before using R.U.B.E (Really useful box2d editor), a very powerful tool that saves us a lot of time, But if we decide to make a

General information is as follows:Ping this word originates from sonar positioning, and this program does the same, and it uses the ICMP protocol packet to detect whether another host is up or down.

Background: The project uses an ant script package but requires MAVEN to perform a sonar code scan. So the project has both Build.xml and Pom.xmlBuild.xml set the package after the product folder for Target,maven run will also default to generate the target folder, so there is a problem of overwritingBecause MAVEN package generates the target folder by default,So you can only modify the ant Package Storage folder, not the same name as the Maven folder

(reference) TCP/IP detailed, Volume 1: protocolThe name "ping" is derived from the sonar positioning operation. The goal is to test whether another host can be reached. The program sends an ICMP echo request message to the host and waits to return an ICMP echo reply.In general, you cannot telnet or FTP to a host computer if you cannot ping it. Conversely, if you can't telnet to a host, you can usually use a ping program to determine where the problem
there is a gap, how to do it? So we are ready to find a closest template engine to carry out a certain expansion, pick to pick the Jetbrick this template language (in this jetbrick to extend a strong heartfelt thanks!! )。There are several reasons why you should choose this:

In this way, the computation of different implementation structures is one-fold.Storage demand is mainly designed to the cost of the system hardware resources, thus affecting the cost of the system. When the implementation structure is chosen, it is hoped that the required storage capacity is as sma

If you use the root partition to record data, such as log files, a large number of logs or spam may be generated due to denial of service, resulting in system crash. Therefore, we recommend that you create separate partitions for/var to store logs and emails to avoid overflow of the root partition. It is best to separate a partition for a special application, especially for programs that can generate a large number of logs. We also recommend that you separate

Recommendation 6: Identify code configuration items and non-configuration items. Examples of non-configuration items include the target directory,. Class file,. clashpath,. Project,. Sonar, thumbs, and debug folder. The ignore function is used to ignore non-configuration items. The code configuration items must be complete, and the same results can be compiled elsewhere without interfering with the working environment elsewhere.
