Mariadb安裝之後的各種設定
阿新 • • 發佈:2019-01-01
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。
