CentOS 7.0 使用 yum 安裝 MariaDB 與 MariaDB 的簡單配置

1、安裝MariaDB

安裝命令

yum -y install mariadb mariadb-server
安裝完成MariaDB，首先啟動MariaDB

systemctl start mariadb
設(shè)置開機啟動

systemctl enable mariadb
接下來進行MariaDB的相關(guān)簡單配置

mysql_secure_installation
首先是設(shè)置密碼，會提示先輸入密碼

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

設(shè)置密碼

Set root password? [Y/n] <– 是否設(shè)置root用戶密碼，輸入y并回車或直接回車
New password: <– 設(shè)置root用戶的密碼
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，回車

Disallow root login remotely? [Y/n] <–是否禁止root遠程登錄,回車,

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

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

初始化MariaDB完成，接下來測試登錄

mysql -uroot -ppassword
完成。

2、配置MariaDB的字符集

文件/etc/my.cnf

vi /etc/my.cnf
在[mysqld]標簽下添加

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，設(shè)置權(quán)限

創(chuàng)建用戶命令

mysql>create user username@localhost identified by 'password';
直接創(chuàng)建用戶并授權(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;
簡單的用戶和權(quán)限配置基本就這樣了。

其中只授予部分權(quán)限把 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。
