第一步: vim /etc/mysql/my.cnf找到 bind-address = 127.0.0.1 注释掉 这行,如:#bind-address = 127.0.0.1 或者改为: bind-address = 0.0.0.0 允许任意IP访问; 或者自己指定一个IP地址。 重启 MySQL: sudo /etc/init.d/mysql restart 第二步: 授权用
第一步:
vim /etc/mysql/my.cnf找到bind-address = 127.0.0.1
注释掉这行,如:#bind-address = 127.0.0.1
或者改为: bind-address = 0.0.0.0
允许任意IP访问;
或者自己指定一个IP地址。
重启 MySQL:sudo /etc/init.d/mysql restart
第二步:
授权用户能进行远程连接
grant all privileges on *.* to root@"%" identified by "password" with grant option;
flush privileges;
第一行命令解释如下,*.*:第一个*代表数据库名;第二个*代表表名。这里的意思是所有数据库里的所有表都授权给用户。root:授予root账号。“%”:表示授权的用户IP可以指定,这里代表任意的IP地址都能访问MySQL数据库。“password”:分配账号对应的密码,这里密码自己替换成你的mysql root帐号密码。
第二行命令是刷新权限信息,也即是让我们所作的设置马上生效。
grant allprivileges on *.* to 'root'@'192.168.30.253' identified by 'password';
flushprivileges;

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
