Disable MySQL Command History

低级别 2自动化mysql

说明

On Linux/UNIX, the MySQL client and MySQL Shell log statements executed interactively to a history file. The default MySQL Client file is named .mysql_history in the user's home directory. The files are split by language and named history.sql, history.js and history.py. Most interactive commands run in the MySQL client application are saved to a history file. Run as root; counts client history files under /home and /root that are not symlinks to /dev/null.

For each user remove the history file and prevent re-creation: rm -f ~<user>/.mysql_history && ln -s /dev/null ~<user>/.mysql_history, or export MYSQL_HISTFILE=/dev/null in the shell startup script; for MySQL Shell remove ~/.mysqlsh/history.* and run \option --persist history.autoSave=0.
