新建一個源 迅雷日租vip加qq114929519,免費vpn訪問 58jiasu.com
vi /etc/yum.repos.d/MariaDB.repo
添加如下內容
[mariadb] name = MariaDB baseurl = http://mirrors.aliyun.com/mariadb/yum/10.3/centos7-amd64/ gpgkey = http://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDB gpgcheck = 1 保存退出 開始yum安裝 yum -y install MariaDB-server MariaDB-client安裝完成MariaDB,首先啟動MariaDB
systemctl start mariadb
設置開機啟動
systemctl enable mariadb
接下來進行MariaDB的相關簡單配置
mysql_secure_installation
首先是設置密碼,會提示先輸入密碼
Enter current password for root (enter for none):<–初次運行直接回車
設置密碼
Set root password? [Y/n] <– 是否設置root用戶密碼,輸入y並回車或直接回車
New password: <– 設置root用戶的密碼
Re-enter new password: <– 再輸入一次你設置的密碼
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,接下來測試登錄
mysql -uroot -ppassword
完成。
2、配置MariaDB的字元集
文件/etc/my.cnf
vi /etc/my.cnf
添加
[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
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
之後進入MariaDB查看字元集
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)
字元集配置完成。
3、添加用戶,設置許可權
創建用戶命令
mysql>create user username@localhost identified by 'password';
直接創建用戶並授權的命令
mysql>grant all on *.* to username@localhost indentified by 'password';
授予外網登陸許可權
mysql>grant all privileges on *.* to username@'%' identified by 'password';
授予許可權並且可以授權
mysql>grant all privileges on *.* to username@'hostname' identified by 'password' with grant option;
簡單的用戶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。
最後,如果你是用的國外伺服器,記得還要設置一個時區 default-time-zone = '+8:00'
