如今在服務器配置數據庫,通常都會直接配置MariaDB,它能夠實現mysql數據庫鏈接。mysql
1、安裝MariaDBsql
安裝命令數據庫
yum -y install mariadb mariadb-server服務器
安裝完成MariaDB,首先啓動MariaDBide
systemctl start mariadb測試
設置開機啓動ui
systemctl enable mariadbspa
接下來進行MariaDB的相關簡單配置rest
mysql_secure_installationcode
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
其餘配置
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遠程登陸,回車,
Remove test database and access to it? [Y/n] <– 是否刪除test數據庫,回車
Reload privilege tables now? [Y/n] <– 是否從新加載權限表,回車
初始化MariaDB完成,接下來測試登陸
mysql -uroot -ppassword
完成。
2、配置MariaDB的字符集
文件/etc/my.cnf
vi /etc/my.cnf
在[mysqld]標籤下添加
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
所有配置完成,重啓mariadb
systemctl restart mariadb
以後進入MariaDB查看字符集
mysql> show variables like "%character%";show variables like "%collation%";
顯示爲
+--------------------------+----------------------------+
| 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,設置權限
建立用戶命令
mysql>create user root@localhost identified by 'password';
直接建立用戶並受權的命令
mysql>grant all on *.* to root@localhost indentified by 'password';
授予外網登錄權限
mysql>grant all privileges on *.* to root@'%' identified by 'password';
授予權限而且能夠受權
mysql>grant all privileges on *.* to root@'hostname' identified by 'password' with grant option;
簡單的用戶和權限配置基本就這樣了。
,在mysqld下面添加skip-grant-tables,保存退出。
1.進入mysql數據庫:
mysql> use mysql;Database changed
Query OK, 1 rows affected (0.04 sec)Rows matched: 1 Changed: 1 Warnings: 0
Query OK, 0 rows affected (0.01 sec)
Bye
PS:123456爲新密碼,用戶可根據本身須要修改爲本身的密碼
改好以後,再修改一下my.ini這個文件,把咱們剛纔加入的"skip-grant-tables"這行刪除,保存退出再重啓mysql服務就能夠了。
systemctl restart mariadb
切記:在配置時要容許遠程登陸,不然只有localhost能登陸數據庫。
