Centos 6 安装Mariadb

版本：

centos 6.8

Mariadb 5.5.61

1、在/etc/yum.repos.d/目录创建MariaDB.repo文件，内容如下：

# MariaDB 5.5 CentOS repository list - created 2014-03-04 11:20 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

这个官方源太卡，换成国内源：

baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/5.5/centos6-amd64
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB

2、使源文件生效：

yum repolist all

3、开始安装：

yum install MariaDB-server MariaDB-client

4、启动登录

在centos7上用service mariadb start 就行，在cenos6上不行，试了 systemctl start mariadb也不行，使用了以下方式：

[root@IChen /]# service mysql start
Starting MariaDB.180828 11:28:31 mysqld_safe Logging to '/var/lib/mysql/webserver.err'.
180828 11:28:31 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
. SUCCESS!
[root@IChen /]# mysql -uroot
Welcome to the MariaDB monitor.  Commands end with ; or \g.

MariaDB [(none)]>

终于装上了。

5、修改root密码：

[root@IChen /]# mysqladmin -u root password '123456'
[root@IChen /]# mysqladmin -uroot -p123456 password '123'

6、允许root用户远程连接

MariaDB [(none)]> use mysql
 
MariaDB [mysql]> grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
Query OK, 0 rows affected (0.00 sec)
 
MariaDB [mysql]> select host,user,password from user;
+-----------+------+-------------------------------------------+
| host      | user | password                                  |
+-----------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| webserver | root |                                           |
| 127.0.0.1 | root |                                           |
| ::1       | root |                                           |
| localhost |      |                                           |
| webserver |      |                                           |
| %         | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
+-----------+------+-------------------------------------------+
7 rows in set (0.00 sec)
 
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

远程连接

mysql -h 127.0.0.1 -P 3306 -u root -p 123456

7、导入文件

use abc;
set names utf8;
source /home/abc/abc.sql;

[root@IChen /]# mysql -uroot -p123456 abc < test.sql
