centos7安裝mariadb
安裝
yum -y install mariadb mariadb-server
安裝完成MariaDB，首先啟動MariaDB
systemctl start mariadb
設(shè)置開機(jī)啟動
systemctl enable mariadb
MariaDB的相關(guān)簡單配置
- 初始化
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(yùn)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(yuǎn)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
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
- 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。
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。
遠(yuǎn)程連接授權(quán)：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
授權(quán)后執(zhí)行
flush privileges
