交互如下:
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: y
There are three levels of password validation policy:
LOW Length = 8
MEDIUM Length = 8, numeric, mixed case, and special characters
STRONG Length = 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 =
STRONG: 2 ===== 注意這里一定要選 2,STRONG
Please set the password for root here.
New password:
Re-enter new password:
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
localhost . This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named test that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!
3. 不使用 sudo
訪問 MySQL($ mysql -uroot -p)要求對 MySQL 設置最高密碼強度
Please enter 0 = LOW, 1 = MEDIUM and 2 =
4. 啟動 MySQL
sudo
systemctl start mysql.servicesudo
systemctl enable mysql.servicesudo
5. 權限設定(可選)
mysql use mysql;
mysql select User,Host,plugin from user;
+------------------+-----------+-----------------------+
| User | Host | plugin |
+------------------+-----------+-----------------------+
| root | localhost | auth_socket -- 這里 |
| mysql.session | localhost | mysql_native_password |
| mysql.sys | localhost | mysql_native_password |
| debian-sys-maint | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
mysql update user set plugin= mysql_native_password where User= root and Host= localhost
mysql GRANT ALL PRIVILEGES ON *.* TO root @ localhost
mysql flush privileges;
6. 修改字符集為 UTF-8
mysql show variables like char% mysql show variables like collation%sudo
vim /etc/mysql/conf.d/mysql.cnf [mysql] default-character-set = utf8sudo
vim /etc/mysql/mysql.conf.d/mysqld.cnf [mysqld] collation-server = utf8_general_ci character-set-server = utf8sudo
7. 查看運行狀態
sudo
systemctl status mysql.servicesudo
lsof -i:3306 netstat -ntpl | grep
