The following article mainly describes the MySQL database simple and practical optimization of the implementation of the specific methods, including how to regularly analyze and check the table, and how to properly optimize the table, the following is the description of the specific plan, I hope that in your future study will help.
1. Regular analysis table and checklist

It applies to some features that can only be measured indirectly, such as usability, flexibility, and so on. Generally, the quality characteristics of the development of a checklist, through the control of the inspection project, to determine whether a quality characteristics.

◆ If you are not in the database directory, you can specify the directory path:
Shell> myisamchk options/path/to/database_dir/*. MYIshell> isamchk options/path/to/database_dir/*. ISM
◆ You can even specify a wildcard for the path of the MySQL data directory to act on all tables in all databases:
Shell> myisamchk options/path/to/datadir/*. MYIshell> isamchk options/path/to/database_dir/*. ISM

Periodic analysis table
ANALYZE [LOCAL | NO_WRITE_TO_BINLOG] TABLE tbl_name [, tbl_name]
This statement is used to analyze and store the table's keyword distribution. During the analysis, a read lock is used to lock the table. This applies to MyISAM, BDB, and InnoDB tables. For MyISAM tables, this statement is equivalent to myisamchk-.
MySQL uses the distribution of stored keywords to determine the order in which tables are joined when you perform union on objects other than constants.

This problem is very depressing and should not occur. I found the problem after checking the information:

To repair a table, use the repair lock protocol of the table.◆ If skip_locaking is on, the external lock is disabled. Therefore, checking and repairing myisamchk or isamchk indicates that the server is unknown. You are advised to disable the server. If the server is always on, make sure that you use this to indicate that no client is allowed to access it. The clientworker lock protocol must be used
for reviewing the Code is to ensure that the code can be securely protected by sufficient information and resources, therefore, it is very important to be familiar with the business process of the entire application to control potential risks. Reviewers can use questions similar to the following to interview developers to collect application information.
