Mariadb安裝之後的各種設定

1、啟動MariaDB

安裝完成MariaDB,首先啟動MariaDB,兩條命令都可以

systemctl start mariadb

或者

service mariadb start

設定開機啟動

systemctl enable mariadb

或者:

chkconfig mariadb on

2、接下來進行MariaDB的相關簡單配置

mysql_secure_installation

首先是設定密碼,會提示先輸入密碼

Enter current password for root (enter for none):<–初次執行直接回車

設定密碼

Set root password? [Y/n] <– 是否設定root使用者密碼,輸入y並回車或直接回車
New password: <– 設定root使用者的密碼
Re-enter new password: <– 再輸入一次你設定的密碼

其他配置

Remove anonymous users? [Y/n] <– 是否刪除匿名使用者,回車

Disallow root login remotely? [Y/n] <–是否禁止root遠端登入,回車,

Remove test database and access to it? [Y/n] <– 是否刪除test資料庫,回車

Reload privilege tables now? [Y/n] <– 是否重新載入許可權表,回車

初始化MariaDB完成,接下來測試登入

mysql -uroot -p [回車,之後輸入密碼]

完成。

3、配置MariaDB的字符集

設定客戶端:

vim /etc/my.cnf.d/mysql-clients.cnf

[mysql]
default-character-set=utf8

設定服務端:

vim /etc/my.cnf.d/server.cnf

[mysqld]
init_connect='SET collation_connection = utf8_general_ci'
init_connect='SET NAMES utf8'
character
-set-server=utf8 collation-server=utf8_general_ci skip-character-set-client-handshake #開啟慢查詢 slow_query_log = ON slow_query_log_file = /usr/local/mysql/data/slow.log long_query_time = 1

全部配置完成,重啟mariadb

systemctl restart mariadb

之後進入MariaDB檢視字符集

mysql> show variables like "%character%";show variables like "%collation%";

顯示為


MariaDB [(none)]> show variables like "%character%";show variables like "%collation%";
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database   | utf8_general_ci |
| collation_server     | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)

字符集配置完成。

4、新增使用者,設定許可權

建立使用者命令

mysql>create user username@localhost identified by 'password';

直接建立使用者並授權的命令

mysql>grant all on *.* to [email protected] indentified by 'password';

授予外網登陸許可權,但不能二級授權;

mysql>grant all privileges on *.* to [email protected]'%' identified by 'password';

授予許可權並且可以二次授權

mysql>grant all privileges on *.* to [email protected]'hostname' identified by 'password' with grant option;

簡單的使用者和許可權配置基本就這樣了。
其中只授予部分許可權把 其中 all privileges或者all改為:
select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file
其中一部分。
