win10环境搭建MariaDB数据库

• 　　1、本次搭建mysql数据，选择了是和mysql类似的MariaDB,完全可以满足日常的使用需求，且命令和mysql没有太大的区别。

对应MariaDB下载地址：https://downloads.mariadb.org/

下载的文件：

• 2、解压下载完成的文件，这里我解压到了D盘，路径：D:mariadb-10.4.7-winx64

• 3、使用win+R，输入CDM，进入DOS控制台。输入命令cd D:mariadb-10.4.7-winx64 ，进入MariaDB的对应的路径中

如图所示：

• 4、执行安装的命令：

mysqld.exe --install MariaDB 

注： 如果执行以上的安装命令出现错误，请使用管理员的身份打开cmd

• 5、开启服务与关闭服务的命令：

net start MariaDB                #开启服务

net stop MariaDB                 #停止服务

此时容易出现一些错误，笔者这里就出现了1067的错误信息：

D:mariadb-10.4.7-winx64in>net start MariaDB
mariadb 服务正在启动 ...
mariadb 服务无法启动。

系统出错。

发生系统错误 1067。

进程意外终止。

尝试了一些方法

进入到Mariadb的文件夹，data下面会有一个文件：主机名.err ，如下图

使用文本格式打开该文件，即可查看到对应的错误信息，类似：

笔者这里解决的办法： 初始化mysql：mysql_install_db

D:mariadb-10.4.7-winx64in>mysql_install_db
Default data directory is D:mariadb-10.4.7-winx64data
Running bootstrap
2019-08-23 10:51:36 0 [Note] D:mariadb-10.4.7-winx64inmysqld.exe (mysqld 10.4.7-MariaDB) starting as process 15452 ...
Removing default user
Creating my.ini file
Creation of the database was successful

执行以上的命令后，系统会在MariaDb安装文件下的data生成对应的文件。然后再次执行启动服务：

D:mariadb-10.4.7-winx64in>net start MariaDB
mariadb 服务正在启动 .
mariadb 服务已经启动成功。

• 6、在CMD窗口，对应MariaDB的bin目录中执行：mysql -u root -p，如下：输入密码时，直接Enter，直接进入MariaDM模式

D:mariadb-10.4.7-winx64in>mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MariaDB connection id is 9
Server version: 10.4.7-MariaDB mariadb.org binary distribution

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]>

• 7、由于新的数据库是没有密码的，所以需要进行设置密码的操作命令：SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');

如下：

MariaDB [(none)]> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root'););
Query OK, 0 rows affected (0.001 sec)

注：红色的字体代表，需要增加的密码。笔者这里设置数据库密码是root。

8、可以通过mysql shell的命名查MariaDB数据库的库名信息：

D:mariadb-10.4.7-winx64in>mysql -u root -p
Enter password: ****
Welcome to the MariaDB monitor. Commands end with ; or g.
Your MariaDB connection id is 10
Server version: 10.4.7-MariaDB mariadb.org binary distribution

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.
