Windows Server2019安装MySQL5.7.25的方法
将解压文件放置C盘
配置环境变量 Patch:C:\mysql-5.7.25-winx64\bin;
安装mysql
切换到bin目录 cd C:*\bin
1.mysqld --initialize --console 打印root用户的初始密码 (失败删除data文件重新执行)
root@localhost:后面的“rI5rvf5x5G,E”就是初始密码(不含首位空格)。在没有更改密码前,需要记住这个密码,后续登录需要用到
2.安装服务bin目录下执行
mysqld --install mysql
3.启动服务(进入控制台直接运行)
net start mysql启动
4.停止服务
net stop mysql
5.更改密码(bin目录下运行):先要启动服务
?1 2 3 | mysql -u root -p 输入root密码 ALTER USER 'root' @ 'localhost' IDENTIFIED WITH mysql_native_password BY '新密码' ; |
--root远程权限
?1 | grant all PRIVILEGES on test_db.* to 'root' @ '%' identified by '设置的密码' ; |
6.可以用 命令查看一下默认安装的数据库:
?1 2 3 | show databases; use mysql; show tables; |
1 2 3 4 5 6 7 8 9 10 11 12 | mysql> show databases; + --------------------+ | Database | + --------------------+ | information_schema | | mysql | | performance_schema | | sys | + --------------------+ 4 rows in set (0.01 sec) mysql> |
看到默认初始化了mysql数据库,其中user表里面存储MySQL用户信息。我们可以看一下默认MySQL用户:
?1 | select user ,host,authentication_string from mysql. user ; |
1 2 3 4 5 6 7 8 9 10 11 12 | mysql> select user ,host,authentication_string from mysql. user ; + ------------------+-----------+-------------------------------------------+ | user | host | authentication_string | + ------------------+-----------+-------------------------------------------+ | mysql.infoschema | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | mysql.session | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | mysql.sys | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | root | localhost | *27C237A977F4F44D3F551F1A673BE14DFD232961 | + ------------------+-----------+-------------------------------------------+ 4 rows in set (0.00 sec) mysql> |
管理员root的host是localhost,代表仅限localhost登录访问。如果要允许开放其他ip登录,则需要添加新的host。如果要允许所有ip访问,可以直接修改成“%”
创建用户:
?1 | CREATE USER 'username' @ '%' IDENTIFIED WITH mysql_native_password BY 'password' ; |
示例
?1 2 3 | CREATE USER 'dog' @ 'localhost' IDENTIFIED BY '123456' ; CREATE USER 'pig' @ '192.168.1.101_' IDENDIFIED BY '123456' ; CREATE USER 'pig' @ '%' IDENTIFIED BY '123456' ; |
(需要注意:mysql8.0加密方式修改了)
检查用户
?1 | select user , host, plugin, authentication_string from user \G; |
授权远程数据库
授权所有权限
?1 | GRANT ALL PRIVILEGES ON *.* TO 'xxh' @ '%' ; |
授权基本的查询修改权限,按需求设置
?1 | GRANT SELECT , INSERT , UPDATE , DELETE , CREATE , DROP , ALTER ON *.* TO 'xxh' @ '%' ; |
查看用户权限
?1 | show grants for 'xxh' @ '%' ; |
示例:
?1 2 3 4 5 | mysql> use mysql; Database changed mysql> CREATE USER 'xxh' @ '%' IDENTIFIED WITH mysql_native_password BY 'xxh123!@#' ; #创建用户(注意:mysql8.0加密方式修改了) Query OK, 0 rows affected (0.07 sec) mysql> |
查看密码加密方式:
?1 2 3 4 5 6 7 8 9 10 11 12 13 | mysql> select user , host, plugin, authentication_string from user ; + ------------------+-----------+-----------------------+-------------------------------------------+ | user | host | plugin | authentication_string | + ------------------+-----------+-----------------------+-------------------------------------------+ | xxh | % | mysql_native_password | *70FD6FB4F675E08FF785A754755B5EBA6DA62851 | | mysql.infoschema | localhost | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | mysql.session | localhost | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | mysql.sys | localhost | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | root | localhost | mysql_native_password | *27C237A977F4F44D3F551F1A673BE14DFD232961 | + ------------------+-----------+-----------------------+-------------------------------------------+ 5 rows in set (0.00 sec) mysql> |
另外,如果需要新增账户,或者本机以外的其他人访问MySQL则还需要设置内置账户的host,具体可以参考:MySQL创建用户与授权
登录MySQL
?1 | mysql> 键入命令mysql -uroot -p, 回车后提示你输入密码,输入12345,然后回车即可 |
