CentOS 7.0 使用 yum 安装 MariaDB 与 MariaDB 的简单配置
安装MariaDB
安装命令
yum -y install mariadb mariadb-server
安装完成MariaDB,首先启动MariaDB
systemctl start mariadb
设置开机启动
systemctl enable mariadb
接下来进行MariaDB的相关简单配置
mysql_secure_installation
首先是设置密码,会提示先输入密码
Enter current password for root (enter for none): -->初次运行直接回车
设置密码
Set root password? [Y/n] //是否设置root用户密码
New password: //设置root用户的密码
Re-enter new password: //再输入一次你设置的密码
其他配置
Remove anonymous users? [Y/n] // 是否删除匿名用户
Disallow root login remotely? [Y/n] //是否禁止root远程登录
Remove test database and access to it? [Y/n] //是否删除test数据库
Reload privilege tables now? [Y/n] // 是否重新加载权限表
初始化MariaDB完成, 测试登录
mysql -uroot -ppassword
完成。
配置MariaDB的字符集
<!-- 文件/etc/my.cnf中添加 -->
[mysqld]
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中添加 -->
[client]
default-character-set=utf8
<!-- #文件/etc/my.cnf.d/mysql-clients.cnf中添加 -->
[mysql]
default-character-set=utf8
全部配置完成,重启mariadb
systemctl restart mariadb
之后进入MariaDB查看字符集
show variables like "%character%";
show variables like "%collation%";
显示为
+--------------------------+----------------------------+
| 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。
建立数据库时可以使用以下命令:
create database app_relation character set utf8;
use app_relation;
source app_relation.sql;
修改数据库编码的命令为:
alter database app_relation character set utf8;
