centos7下MariaDB安裝和簡(jiǎn)單配置

1、安裝MariaDB

安裝命令

yum -y install mariadb mariadb-server

安裝完成MariaDB,首先啟動(dòng)MariaDB

systemctl start mariadb

設(shè)置開(kāi)機(jī)啟動(dòng)

systemctl enable mariadb

接下來(lái)進(jìn)行MariaDB的相關(guān)簡(jiǎn)單配置

mysql_secure_installation

首先是設(shè)置密碼,會(huì)提示先輸入密碼

Enter current password for root (enter for none):<–初次運(yùn)行直接回車(chē)

設(shè)置密碼

Set root password? [Y/n] <– 是否設(shè)置root用戶(hù)密碼,輸入y并回車(chē)或直接回車(chē)

New password: <– 設(shè)置root用戶(hù)的密碼

Re-enter new password: <– 再輸入一次你設(shè)置的密碼

其他配置

Remove anonymous users? [Y/n] <– 是否刪除匿名用戶(hù),回車(chē)

Disallow root login remotely? [Y/n] <–是否禁止root遠(yuǎn)程登錄,回車(chē),

Remove test database and access to it? [Y/n] <– 是否刪除test數(shù)據(jù)庫(kù),回車(chē)

Reload privilege tables now? [Y/n] <– 是否重新加載權(quán)限表,回車(chē)

初始化MariaDB完成,接下來(lái)測(cè)試登錄

mysql -uroot(-u用戶(hù)名) -ppassword(-p用戶(hù)密碼)

完成。

2、配置MariaDB的字符集

文件/etc/my.cnf

vi /etc/my.cnf

在[mysqld]標(biāo)簽下添加

init_connect='SET collation_connection = utf8_unicode_ci'

init_connect='SET NAMES utf8'

character-set-server=utf8

collation-server=utf8_unicode_ci

skip-character-set-client-handshake

文件/etc/my.cnf.d/client.cnf

vi /etc/my.cnf.d/client.cnf

在[client]中添加

default-character-set=utf8

文件/etc/my.cnf.d/mysql-clients.cnf

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

在[mysql]中添加

default-character-set=utf8

全部配置完成,重啟mariadb

systemctl restart mariadb

之后進(jìn)入MariaDB查看字符集

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

顯示為

+--------------------------+----------------------------+

| 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_unicode_ci |

| collation_database  | utf8_unicode_ci |

| collation_server    | utf8_unicode_ci |

+----------------------+-----------------+

3 rows in set (0.00 sec)

字符集配置完成。

3、添加用戶(hù),設(shè)置權(quán)限

創(chuàng)建用戶(hù)命令

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

直接創(chuàng)建用戶(hù)并授權(quán)的命令

mysql>grant all on *.* to username@localhost indentified by 'password';

授予外網(wǎng)登陸權(quán)限

mysql>grant all privileges on *.* to username@'%' identified by 'password';

授予權(quán)限并且可以授權(quán)

mysql>grant all privileges on *.* to username@'hostname' identified by 'password' with grant option;

簡(jiǎn)單的用戶(hù)和權(quán)限配置基本就這樣了。

附加:

通過(guò)CREATE USER命令進(jìn)行創(chuàng)建用戶(hù)

腳本:CREATE USER 'username'@'host' [IDENTIFIED BY 'PASSWORD'] 其中密碼是可選項(xiàng);

例子:CREATE USER 'john'@'192.168.189.71' IDENTIFIED BY "123";

CREATE USER 'john'@'192.168.189.%' IDENTIFIED BY "123";

CREATE USER 'john'@' %' ;

說(shuō)明:該方法創(chuàng)建出來(lái)的用戶(hù)只有連接數(shù)據(jù)庫(kù)的權(quán)限,需要后續(xù)繼續(xù)授權(quán);
