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。
