After installing mysql on the server, you generally need to do the following:

• 1. Start mysql server
• 2. Set the root user and add some Access Users
• 3. Set User Permissions
• 4. Configure non-local connection access
• 5. Back up or migrate data
• 6. Some precautions (Continuous updates)

1. Start mysql server

Generally, the following startup commands are used:

Service mysqld start

A common problem is:Timeout error occurred trying to start MySQL Daemon

The solution is also simple: simply execute

/Usr/bin/mysql_install_db

The directory may be different. The default installation is usually here.

View the service status of mysql:

/Etc/rc. d/init. d/mysqld status

2. Set the root user and add some Access Users

By default, the root account of mysql does not have a password after installation. Generally, a password is set for root to ensure security:

Mysql> update user set password = PASSWORD ('000000') where User = 'root ';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0
Mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

3. Set User Permissions

Of course, mysql is provided to users and needs to be added to users:

Mysql> insert into mysql. user (Host, User, Password) values ('localhost', 'admin', password ("admin "));
Query OK, 1 row affected, 3 warnings (0.01 sec)
Mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

Now a new user admin/admin is added, but the user has not been assigned any permissions yet.

Mysql> grant ALL on *. * to admin @ "%" Identified by "admin ";
Query OK, 0 rows affected (0.00 sec)

% Represents any host. Of course, only select, insert, update, and delete operations can be granted:

Mysql> grant select, insert, update, delete on *. * to admin @ "%" Identified by "admin ";
Query OK, 0 rows affected (0.00 sec)
Mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

4. Configure non-local connection access

By default, remote users are not allowed to access local databases. You need to execute commands to grant data access permissions to any host or related host:

Mysql> update user set host = '%' where user = 'admin ';

You can use the admin user to access data on any host.

Or:

Mysql> grant all privileges on *. * TO 'root' @ '%' WITH GRANT OPTION

5. Back up or migrate data

It is easier to use mysqldump. refer to the previous general article: Mysql Database Import and export.

6. Notes

In linux, the default mysql table name is case-sensitive. to rename a table that is case-insensitive, follow these steps.

• 1. Log On with root and modify/etc/my. cnf
• 2. Add a row under [mysqld]: lower_case_table_names = 1
• 3. Restart the database.
