linux下安装mariadb

闲置已久的空间环境配置忘得差不多了,今天得空整理,重置了磁盘重新搭建环境,首先在CentOS 7.0安装MariaDB的数据库,在这里记录下安装过程,以便以后查看。

1、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,输入y并回车或直接回车 
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,回车

Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,

Remove test database and access to it? [Y/n] <– 是否删除test数据库,回车

Reload privilege tables now? [Y/n] <– 是否重新加载权限表,回车

初始化MariaDB完成,接下来测试登录

mysql -u root -p password

完成。

2、配置MariaDB的字符集

文件/etc/my.cnf

vi /etc/my.cnf

在[mysqld]标签下添加

initconnect='SET collationconnection = utf8unicodeci' 
initconnect='SET NAMES utf8' 
character-set-server=utf8 
collation-server=utf8unicode_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,重启mariadb

systemctl restart mariadb

之后进入MariaDB查看字符集

mysql> show variables like "%character%";show variables like "%collation%";

显示为

+--------------------------+----------------------------+ | Variablename | Value | +--------------------------+----------------------------+ | charactersetclient | utf8 | | charactersetconnection | utf8 | | charactersetdatabase | utf8 | | charactersetfilesystem | binary | | charactersetresults | utf8 | | charactersetserver | utf8 | | charactersetsystem | utf8 | | charactersets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)

+----------------------+-----------------+ | Variablename | Value | +----------------------+-----------------+ | collationconnection | utf8unicodeci | | collationdatabase | utf8unicodeci | | collationserver | utf8unicodeci | +----------------------+-----------------+ 3 rows in set (0.00 sec)

字符集配置完成。

3、添加用户,设置权限

创建用户命令

mysql>create user username@localhost identified by 'password';

直接创建用户并授权的命令

mysql>grant all on . to username@localhost indentified by 'password';

授予外网登陆权限

mysql>grant all privileges on . to username@'%' identified by 'password';

授予权限并且可以授权

mysql>grant all privileges on . to username@'hostname' identified by 'password' with grant option;

简单的用户和权限配置基本就这样了。
