CentOS7下yum安装MariaDB与简单配置
开始之前要确保已经安装yum并且配置好相关的源。
一、 安装命令：
yum -y install mariadb mariadb-server
二、启动MariaDB
systemctl start mariadb
三、 设置开机启动
systemctl enable mariadb
四、相关配置
mysql_secure_installation
1. 设置密码
Enter current password for root (enter for none): #直接回车就行
Set root password? [Y/n] y # 设置密码
New password:
Re-enter new password:
Remove anonymous users? [Y/n] # 是否删除匿名用户，删除就行
Disallow root login remotely? [Y/n] n # 是否禁止root远程登录，N
Remove test database and access to it? [Y/n] # 是否删除测试表，Y
Reload privilege tables now? [Y/n] # 是否重新加载权限表，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. 登录
mysql -uroot -proot
3. 配置MariaDB的字符集
a. 查看数据库字符集
show variables like "%character%";show variables like "%collation%";
显示如下
+--------------------------+----------------------------+
| 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]标签下添加
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.重启MariaDB
systemctl restart mariadb
f.查看修改后的字符集
进入数据库
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. 添加用户，设置权限
a.创建用户命令
MariaDB [(none)]> create user inspur@localhost identified by 'inspur';
b. 授权
grant all privileges on *.* to inspur@'localhost' identified by 'inspur';
b.授予外网登录权限
grant all privileges on *.* to root@'%' identified by 'inspur';
