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:

Enter the terminal

Assign 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 it can be written as select,utdate, etc.

*. * refers to all tables in the database

IP address: allowed to connect to the IP address,% to allow 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:

Log in with root, modify / etc/my.cnf

Add a line under [mysqld]: lower_case_table_names=1

Restart mysql
