In this article, we will take a look at common problems and solutions to mysql during development. There is a certain reference value, friends in need can refer to, hope to help you.

Remote connection issu

Mysql default connection can only be given locally (localhost or 127.0.0.1). If you want an ip address to access mysql, you need to enable this permission manually.

Methods:

● enters the terminal

● assigns new users

Grant all privileges on *. * to 'username' @'IP address' identified by 'password'

● refresh permissions

Flush privileges

If you want all machines on the local area network to connect to the mysql database, execute the following command

Grant all privileges on *. * to 'username' @'% 'identified by' password 'with grant option

● all privileges refers to all permissions, or can be written as select,utdate, etc.

● *. * refers to all tables in the database

● IP address: IP address allowed to connect,% is allowed for all machines in the LAN

Reserved word problem

Reserved words like index in mysql should be avoided in development. If index is used, the sql uses anti-single quotation marks to handle ``(the key under Esc).

Table case problem

In windows, mysql is not case-sensitive, but in linux, mysql is case-sensitive, and in linux, mysql is case-insensitive:

● login with root, modify / etc/my.cnf

● adds a line under [mysqld]: lower_case_table_names=1

● restart mysql

The above is a brief introduction to the common problems and solutions of mysql in the development process. Of course, the differences in the detailed use of the above have to be understood by everyone. If you want to know more, welcome to follow the industry information channel!
