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);
