代码如下:
# vi mysqlusers.txt
create database dataname;
grant all privileges on dataname.* to username@localhost identified by ‘password‘;
flush privileges;
# /usr/local/mysql/bin/mysql -u root -p password
蓝色斜体部分为对应的用户名和密码,添加多个用户及数据库,只需要复制中间部分代码并修改对应的位置即可,如:
代码如下:
create database dataname1;
grant all privileges on dataname1.* to username1>@localhost” identified by ‘password‘;
flush privileges;
create database dataname2;
grant all privileges on dataname2.* to username2>@localhost” identified by ‘password‘;
flush privileges;

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
