Win10下mysql 8.0.20 安装配置方法图文教程
win10系统下mysql 8.0.20安装和配置超详细教程
mysql下载
mysql直接去官网下载就行,选择community版本(免费)下载,链接。
在select operating system中选择microsoft windows,下方对应出现最新版本的mysql,目前是mysql 8.0.20,有两个zip文件,选择第一个windows (x86, 64-bit), zip archive点击右侧的download按钮进行下载
官网下载有时速度比较慢,直接点击链接也可以下载:
安装与配置
将下载好的压缩包解压缩到全英文目录下,比如我在d盘新建了mysql文件夹,解压到该文件夹下,d:/mysql
然后把mysql 8.0.20所在的路径d:\mysql\mysql-8.0.20-winx64添加到环境变量path中
接下来正式安装和配置mysql:
(一)首先在d:\mysql\mysql-8.0.20-winx64路径下创建一个my.ini文件,直接新建文本文档,然后重命名为my.ini即可。
在文档中添加以下内容:
(注意修改basedir和datadir的路径)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | [mysqld] # 设置3306端口 port=3306 # 设置mysql的安装目录 basedir=d:\\mysql\\mysql-8.0.20-winx64 # 此处为mysql的解压缩路径 # 设置mysql数据库的数据的存放目录 datadir=d:\\mysql\\mysql-8.0.20-winx64\\data # 此处同上,先不要在路径中创建data目录,后面初始化时会自动生成 # 允许最大连接数 max_connections=200 # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统 max_connect_errors=10 # 服务端使用的字符集默认为utf8 character - set -server=utf8 # 创建新表时将使用的默认存储引擎 default -storage-engine=innodb # 默认使用“mysql_native_password”插件认证 default_authentication_plugin=mysql_native_password [mysql] # 设置mysql客户端默认字符集 default - character - set =utf8 [client] # 设置mysql客户端连接服务端时默认使用的端口 port=3306 default - character - set =utf8 |
(二)以管理员权限打开cmd(注意要以管理员权限打开),并将路径切换到d:\mysql\mysql-8.0.20-winx64\bin
?1 2 3 4 5 6 7 8 9 10 11 12 | microsoft windows [version 10.0.18363.815] (c) 2019 microsoft corporation。保留所有权利。 c:\windows\system32>d: d:\>cd mysql d:\mysql>cd mysql-8.0.20-winx64 d:\mysql\mysql-8.0.20-winx64>cd bin d:\mysql\mysql-8.0.20-winx64\bin> |
输入mysqld --initialize --console,进行初始化。该步可以得到mysql的初始密码,root@localhost后面那一串就是初始密码,先记录下来,待会要用到
?1 2 3 4 5 6 7 | d:\mysql\mysql-8.0.20-winx64\bin>mysqld --initialize --console 2020-05-10t11:26:21.895908z 0 [system] [my-013169] [server] d:\mysql\mysql-8.0.20-winx64\bin\mysqld.exe (mysqld 8.0.20) initializing of server in progress as process 9764 2020-05-10t11:26:21.897278z 0 [warning] [my-013242] [server] --character-set-server: 'utf8' is currently an alias for the character set utf8mb3, but will be an alias for utf8mb4 in a future release. please consider using utf8mb4 in order to be unambiguous. 2020-05-10t11:26:21.915225z 1 [system] [my-013576] [innodb] innodb initialization has started. 2020-05-10t11:26:22.619057z 1 [system] [my-013577] [innodb] innodb initialization has ended. 2020-05-10t11:26:24.265774z 6 [note] [my-010454] [server] a temporary password is generated for root@localhost: 9zh31zk-@mof |
输入mysqld --install(如果需要安装多个mysql服务,这步输入mysqld --install [服务名])
?1 2 | d:\mysql\mysql-8.0.20-winx64\bin>mysqld --install service successfully installed. |
显示service successfully installed则说明安装成功
输入net start mysql,启动mysql服务
1 2 3 | d:\mysql\mysql-8.0.20-winx64\bin>net start mysql the mysql service is starting. the mysql service was started successfully. |
输入mysql -u root -p,使用初始密码登录mysql,在enter password后输入初始密码
?1 2 3 4 5 6 7 8 9 10 11 12 13 | d:\mysql\mysql-8.0.20-winx64\bin>mysql -u root -p enter password : ************ welcome to the mysql monitor. commands end with ; or \g. your mysql connection id is 8 server version: 8.0.20 copyright (c) 2000, 2020, oracle and / or its affiliates. all rights reserved. oracle is a registered trademark of oracle corporation and / or its affiliates. other names may be trademarks of their respective owners. type 'help;' or '\h' for help. type '\c' to clear the current input statement. |
登录后,把初始密码修改掉,可以设置成自己容易记住的密码。
输入alter user 'root'@'localhost' identified with mysql_native_password by '自己定义的密码'; (分号一定要带)
1 2 | mysql> alter user 'root' @ 'localhost' identified with mysql_native_password by '自己定义的密码; query ok, 0 rows affected (0.02 sec) |
到这一步就完成了
输入show database; ,可以查看包含哪些数据表
1 2 3 4 5 6 7 8 9 10 | mysql> show databases; + --------------------+ | database | + --------------------+ | information_schema | | mysql | | performance_schema | | sys | + --------------------+ 4 rows in set (0.01 sec) |
