目前的CentOS7默认可以安装MarialDB,本文主要针对默认版本。
1、如果要安装最新的版本,需要自己设置安装源
rpm -qa |grep mariadb
yum remove mysql mysql-server mysql-libs compat-mysql51
rpm -e --nodeps mariadb-*

vim /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.1 CentOS repository list - created 2017-02-15 20:31 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

2、开始安装

yum -y install mariadb-server
# 或 
yum -y install MariaDB-server MariaDB-client
安装执行
yum -y install mariadb-server

Complete!

安装完成MariaDB,首先启动MariaDB
systemctl start mariadb

设置为开启启动

systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

3、初始化数据。接下来进行MariaDB的相关简单配置:mysql_secure_installation

mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

#首先是设置密码,会提示先输入密码,初次运行直接回车
Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

#设置密码,是否设置root用户密码,输入Y并回车或直接回车
Set root password? [Y/n] y
#设置root用户的密码
New password:
#再输入一次你设置的密码
Re-enter new password:

#root密码设置成功
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

#是否删除匿名用户,输入Y并回车
Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

#是否禁止root远程登录,输入n并回车
Disallow root login remotely? [Y/n] n
... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

#是否删除test数据库,输入n并回车
Remove test database and access to it? [Y/n] n
... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

#是否重新加载权限表,回车
Reload privilege tables now? [Y/n]
... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

操作执行到这里,数据库的初始化已基本完成。现在测试登录

mysql -h127.0.01 -uroot -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.

4 rows in set (0.00 sec)
4、配置数据库字符集
1)编辑文件/etc/my.cnf
vim /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
#端口
port=3317
2)编辑文件/etc/my.cnf.d/client.cnf
vim /etc/my.cnf.d/client.cnf
#在[client]中添加
default-character-set=utf8
3)编辑文件/etc/my.cnf.d/mysql-clients.cnf
vim /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

 

登陆数据库,查看配置后的字符集信息
MariaDB [(none)]> show variables like "%character%";
+--------------------------+----------------------------+
| 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)

MariaDB [(none)]> show variables like "%collation%";
+----------------------+-----------------+
| 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)

MariaDB [(none)]> select version();
+----------------+
| version()      |
+----------------+
| 5.5.60-MariaDB |
+----------------+
1 row in set (0.00 sec)

 

5、添加用户,设置权限
创建用户:
#创建用户命令:用户名 kftest,密码1234567
create user kftest@localhost identified by '1234567';
#直接创建用户并授权的命令
grant all on *.* to kftest@localhost indentified by '1234567';
授权用户:
#授予外网登陆权限
grant all privileges on *.* to kftest@'%' identified by '1234567';
#授予权限并且可以授权
grant all privileges on *.* to kftest@'hostname' identified by '1234567' with grant option;
简单的用户和权限配置基本就这样了。其中只授予部分权限把 其中 all privileges或者all改为select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file其中一部分。
6、其他
查看MariaDB启动状态:
systemctl status mariadb
systemd重载此配置文件,刚刚配置的服务需要让systemctl能识别,就必须刷新配置:
systemctl daemon-reload
如果没有权限可以使用sudo
sudo systemctl daemon-reload
停止MariaDB服务:
systemctl stop mariadb
禁止开机启动:
systemctl disable mariadb
设置防火墙远程端口
firewall-cmd --zone=public --add-port=3308/tcp --permanent
刷新重启防火墙
firewall-cmd --reload
