本文详细介绍了MySQL服务器的各种配置选项，包括性能调整、安全性设置、日志记录、存储引擎参数等，帮助读者理解如何根据实际需求优化MySQL服务器。
--updatable-views-with-limit=name
YES = Don't issue an error message (warning only) if a
VIEW without presence of a key of the underlying table is
used in queries with a LIMIT clause for updating. NO =
Prohibit update of a VIEW, which does not contain a key
of the underlying table and the query uses a LIMIT clause
(usually get from GUI tools)
--upgrade=name Set server upgrade mode. NONE to abort server if
automatic upgrade of the server is needed; MINIMAL to
start the server, but skip upgrade steps that are not
absolutely necessary; AUTO (default) to upgrade the
server if required; FORCE to force upgrade server.
-u, --user=name Run mysqld daemon as user.
--validate-config Validate the server configuration specified by the user.
--validate-user-plugins
Turns on additional validation of authentication plugins
assigned to user accounts.
(Defaults to on; use --skip-validate-user-plugins to disable.)
-v, --verbose Used with --help option for detailed help.
-V, --version Output version information and exit.
--wait-timeout=# The number of seconds the server waits for activity on a
connection before closing it
--windowing-use-high-precision
For SQL window functions, determines whether to enable
inversion optimization for moving window frames also for
floating values.
(Defaults to on; use --skip-windowing-use-high-precision to disable.)
