Mysql修改密码时报错Can’t Create Thread: Errno 11解决
今天安装完mysql后,想修改一下密码,运行一下
myqladmin -u root password 'password'显示报错,
报错信息如下,
Can't create a new thread (errno 11); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug'
还以为是内存不足的问题,free -m 看了一下没问题。Google一下,说是ulimit 限制了max processes,
进入到/proc/`pidof mysqld`/limits 看了一下 max processes 设置才10
马上ulimit -u 4096
重启mysql service 搞定。

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.
