CentOS7下yum安裝MariaDB與簡單配置
開始之前要確保已經安裝yum並且配置好相關的源。
一、 安裝命令：
yum -y install mariadb mariadb-server
二、啓動MariaDB
systemctl start mariadb
三、 設置開機啓動
systemctl enable mariadb
四、相關配置
mysql_secure_installation
1. 設置密碼
Enter current password for root (enter for none): #直接回車就行
Set root password? [Y/n] y # 設置密碼
New password:
Re-enter new password:
Remove anonymous users? [Y/n] # 是否刪除匿名用戶，刪除就行
Disallow root login remotely? [Y/n] n # 是否禁止root遠程登錄，N
Remove test database and access to it? [Y/n] # 是否刪除測試表，Y
Reload privilege tables now? [Y/n] # 是否重新加載權限表，Y
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
2. 登錄
mysql -uroot -proot
3. 配置MariaDB的字符集
a. 查看數據庫字符集
show variables like "%character%";show variables like "%collation%";
顯示如下
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | utf8_general_ci |
| collation_database | latin1_swedish_ci |
| collation_server | latin1_swedish_ci |
+----------------------+-------------------+
b.修改文件/etc/my.cnf文件
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
c.修改文件 /etc/my.cnf.d/client.cnf
vi /etc/my.cnf.d/client.cnf
在[client]中添加
default-character-set=utf8
d. 修改文件/etc/my.cnf.d/mysql-clients.cnf
vi /etc/my.cnf.d/mysql-clients.cnf
在[mysql]中添加
default-character-set=utf8
e.重啓MariaDB
systemctl restart mariadb
f.查看修改後的字符集
進入數據庫
mysql -uroot -proot
show variables like "%character%";show variables like "%collation%";
MariaDB [(none)]> show variables like "%character%";show variables like "%collation%";
+--------------------------+----------------------------+
| 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)
4. 添加用戶，設置權限
a.創建用戶命令
MariaDB [(none)]> create user inspur@localhost identified by 'inspur';
b. 授權
grant all privileges on *.* to inspur@'localhost' identified by 'inspur';
b.授予外網登錄權限
grant all privileges on *.* to root@'%' identified by 'inspur';
