#DESCR: 4GB RAM, InnoDB only, ACID, few connections, heavy queries
#描述：4GB 內存、只有 InnoDB、ACID、很少連接數、繁重的查詢
#TYPE: SYSTEM
#END CONFIG INFO
#
# This is a MySQL example config file for systems with 4GB of memory
# running mostly MySQL using InnoDB only tables and performing complex
# queries with few connections.
# 這是一個針對 4G 內存系統（主要運行只有 InnoDB 表的 MySQL 並使用幾個連接數執行復雜的查詢）的 MySQL 配置文件例子。
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.
#
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
# 下面的選項將被 MySQL 客戶端應用程序所讀取。
# 注意，只有 MySQL 標准的客戶端應用程序是被保證能讀取到該章節的。
# 如果你希望你自己的 MySQL 客戶端程序能夠承兌這些值，你需要在 MySQL 客戶端庫初始化中作為一個選項來指定它。

# back_log is the number of connections the operating system can keep in
# the listen queue, before the MySQL connection manager thread has
# processed them. If you have a very high connection rate and experience
# "connection refused" errors, you might need to increase this value.
# Check your OS documentation for the maximum value of this parameter.
# Attempting to set back_log higher than your operating system limit
# will have no effect.
# back_log 是指保持在操作系統監聽隊列中的連接數量，即在 MySQL 連接管理器線程處理它們之前的連接數量。
# 如果你有一個非常高的連接率並見到過“拒絕連接”的錯誤，你可能需要提高該值。
# 檢查你的操作系統文檔中該參數 的最大值。
# 試圖將 back_log 設置得高於你操作系統的限制將不會起到任何作用。
back_log = 50
# Don't listen on a TCP/IP port at all. This can be a security
# enhancement, if all processes that need to connect to mysqld run
# on the same host. All interaction with mysqld must be made via Unix
# sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!
# 根本不用監聽一個 TCP/IP 端口。
# 如果運行在相同主機上的所有進程都需要連接到 mysqld，這可能是一個安全增強。
# 所有與 mysqld 的互動都必須通過 Unix sockets（套接字）或命名管道進行。
# 注意，在 Windows 上使用該選項但卻不啟用命名管道（通過“enable-named-pipe”選項）將使得 mysqld 變得無用。
#skip-networking
# The maximum amount of concurrent sessions the MySQL server will
# allow. One of these connections will be reserved for a user with
# SUPER privileges to allow the administrator to login even if the
# connection limit has been reached.
# MySQL 允許的並發會話的最大數量。
# 其中的一個連接將被保留給擁有 SUPER 特權的用戶，即使已經到達了連接限制，仍可以允許管理者登錄。
max_connections = 100
# Maximum amount of errors allowed per host. If this limit is reached,
# the host will be blocked from connecting to the MySQL server until
# "FLUSH HOSTS" has been run or the server was restarted. Invalid
# passwords and other errors during the connect phase result in
# increasing this value. See the "Aborted_connects" status variable for
# global counter.
# 每個主機允許的最大錯誤數量。
# 如果已到達該限制，主機將阻止對 MySQL 服務器的連接，直到運行“FLUSH HOSTS”或者服務器被重啟。
# 在連接階段的無效密碼和其它錯誤將導致該值被提高。
