centos7 安装 mariadb 的正确命令，centos7mariadb
使用的是linode的centos7系统，安装mysql发现已经默认的是mariadb。
但是不管是使用linode官网说明还是百度搜索到的的根本安装方法无法安装成功。
总是提示这一句：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
最后通过google 搜索 install mariadb on centos 7得到了安装的关键一步。
现在安装成功，特此备注一下整个安装过程：
mysql:[root@localhost ~]# yum -y install mariadb*

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.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
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.
Set root password? [Y/n] y
New password:
Re-enter new password:
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.
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.
Disallow root login remotely? [Y/n] y
... Success!
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.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... 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!

yum的元数据的问题？是不是yum源有问题？
Maria 存储引擎 PBXT 存储引擎 XtraDB存储引擎 FederatedX 存储引擎
它的安装与MySQL的noinstall 版本类似。
1.下载并解压 noinstall 压缩包，假设解压到 D:\dev\MariaDB目录下载地址(5.1.44b)：fe.up.pt2. 创建配置文件my.ini
配置文件一般放在Windows系统目录中（也可以放在你的安装目录内），如C:\WINDOWS 或C:\WINNT，名为my.ini 。将上面下载后的文件mariadb-noinstall-5.1.44b-win32-beta.zip解压后，在该文件夹中，一般包含5个MySQL自带的配置文件，my- small.ini、my-medium.ini、my-large.ini、my-huge.ini和my-innodb-heavy-4G.ini，请你根据自己机器的内存大小，选择其一，并把它重新命名为my.ini用作基本配置文件。
配置文件中的一些参数，需要根据安装目录的不同，做相应的修改，如[WinMySQLAdmin]
Server=D:/dev/mariadb/bin/mysqld.exe[mysqld]basedir=D:/dev/mariadb
datadir=D:/dev/mariadb/data
default-character-set=gbkport=3306[client]default-character-set=gbk
port=33063.将MariaDB安装为Windows服务
在D:/dev/mariadb/bin目录下运行 mysqld --install servicename则会创建名为servicename的Windows 服务。将创建完的服务的启动类型设为自动启动，并启动MariaDB。启动MariaDB时，会在data 目录内创建数据文件和日志文件。注：启动后的MariaDB 有一个默认的 root 用户，其访问密码为空。修改密码的方法与MySQL类似，执行如下命令，即可修改root的访问密码。mysqladmin -u root password "password"
