Storage Engine 'Myisam' Does Not Support System Tables
Storage Engine 'Myisam' Does Not Support System Tables. (note that mysql 5.1 does not support isam.) each myisam table is stored on disk in three files. Stores the definition of the table structure (mytable.frm)

[mysql.db] 所以我知道它是 myisam 的 mysql.db 并且需要是其他东西，所以我只是将其更改为 innodb。 希望对某人有所帮助! The files have names that begin with the table name and have an extension to indicate the file type. Set group_concat_max_len permanently (mysql config)
As Of Mysql 5.6, It Is Necessary To Use Engine Clause To Specify The Myisam Storage Engine Because Innodb Is The Default Engine.
As a result, read and write operations conflict with each other. Myisam was the default mysql storage engine prior to the mysql server version 5.5.5. But in a very limited scope:
The solution is to change the storage engine for confluence tables to innodb as recommended in our documentation. If the data you need to attach is more than 3mb, you should create a compressed archive of the data and a readme file that describes the data with a filename that includes the bug number (recommended filename: Myisam has a defect in protecting data integrity, which may cause database data damage or even data loss.
Storage Engine 'Myisam' Does Not Support System Tables.
Set group_concat_max_len permanently (mysql config) This occurs when the mysqldump taken from the source environment contains more than just the ssg database and contains all databases including the mysql system database. As a result, read and write operations conflict with each other.
(Note That Mysql 5.1 Does Not Support Isam.) Each Myisam Table Is Stored On Disk In Three Files.
Myisam is based on the older (and no longer available) isam storage engine but has many useful extensions. Innodb stores its tables and indexes in a tablespace. Working with myisam is harder now (and discouraged):
Myisam Is The Default Storage Engine.
However, it does not do very well when simultaneously reading from and writing to one table, due to its table locking. To specify explicitly that you want a myisam table, indicate that with an engine table option: The myisam storage engine was the only storage engine provided by mysql in 2005 and was available to use for.
