MySQL server initialization (starting from MySQL 5.7): when the server initial startup, if the server's data directory is empty, then the following occurs:
(1), the server is initialized
(2), generate an SSL certificate and key files in the data directory
(3) The validate_password plug-in installed and enabled
(4), will 'root'@'localhost' create a superuser account. Setting a supervisor password and store it in a log file. To show it, use the following command:
# grep "password" /var/log/mysqld.log

After the initial operation of the database in order to enter the password to access the mysql database, it will not do anything, because the default MySQL password must be changed
mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement
Modify the mysql password
Note:
MySQL's validate_password plug-in installed by default. This would require a password containing at least one capital letter, a small letter, a number and a special character, and a total length of a password of at least 8 characters.
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456'; ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> SET PASSWORD = PASSWORD('Admin123!');
mysql> SET PASSWORD = PASSWORD('Admin123!'); Query OK, 0 rows affected, 1 warning (0.00 sec)
MySQL complete the initial password rules can be viewed with the following command:
mysql> SHOW VARIABLES LIKE 'validate_password%';
mysql> SHOW VARIABLES LIKE 'validate_password%'; +--------------------------------------+--------+ | Variable_name | Value | +--------------------------------------+--------+ | validate_password_check_user_name | OFF | | validate_password_dictionary_file | | | validate_password_length | 8 | | validate_password_mixed_case_count | 1 | | validate_password_number_count | 1 | | validate_password_policy | MEDIUM | | validate_password_special_char_count | 1 | +--------------------------------------+--------+ 7 rows in set (0.01 sec)
The password is determined by validate_password_length, and validate_password_length formula is:
validate_password_length = validate_password_number_count + validate_password_special_char_count + (2 * validate_password_mixed_case_count)
If you want to set up a simple password to modify two global parameters:
mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;
mysql> set global validate_password_policy=0; Query OK, 0 rows affected (0.00 sec) mysql> set global validate_password_length=1; Query OK, 0 rows affected (0.00 sec)
View mysql password rules again
mysql> SHOW VARIABLES LIKE 'validate_password%';
mysql> SHOW VARIABLES LIKE 'validate_password%'; +--------------------------------------+-------+ | Variable_name | Value | +--------------------------------------+-------+ | validate_password_check_user_name | OFF | | validate_password_dictionary_file | | | validate_password_length | 4 | | validate_password_mixed_case_count | 1 | | validate_password_number_count | 1 | | validate_password_policy | LOW | | validate_password_special_char_count | 1 | +--------------------------------------+-------+ 7 rows in set (0.00 sec)
At this time, the password can be set very simple, like for example 1234
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456'; Query OK, 0 rows affected (0.00 sec)
You can set up remote login
Authorized remote login
grant all privileges on *.* to root@'%' identified by 'password' with grant option;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'password' WITH GRANT OPTION;
The first is your username root, password is the second remote password
mysql> grant all privileges on *.* to root@'%' identified by '123456' with grant option
flush command to make the configuration take effect immediately
mysql> flush privileges;
mysql> select user,host from mysql.user; +---------------+-----------+ | user | host | +---------------+-----------+ | mysql.session | localhost | | mysql.sys | localhost | | root | localhost | +---------------+-----------+ 3 rows in set (0.00 sec) mysql> grant all privileges on *.* to root@'%' identified by '123456' with grant option; Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> select user,host from mysql.user; +---------------+-----------+ | user | host | +---------------+-----------+ | root | % | | mysql.session | localhost | | mysql.sys | localhost | | root | localhost | +---------------+-----------+ 4 rows in set (0.00 sec)
Or use it to modify the statement authorized remote client login
use mysql;
show tables;
select Host,User from user \G
update user set host = '%' where Host = "localhost" and user = "root";
Modify some simple configuration:
The default character set is Latin character set, each time the database is created to set the character set; default does not support the group by statement, the default time zone is not our current Beijing (East eight districts), will lead us to the time difference 13 points.
Open the configuration file, yum install by default in the / etc folder: /etc/my.cnf
# We /etc/my.cnf
The default configuration is as follows:
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
In [mysqld] Add the following, no semicolon
Character set: utf8, not utf8 Note that!
character-set-server=utf8
View mysql character set
mysql> show variables like 'char%';
The default character set as follows
mysql> show variables like 'char%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)
