不知道大家之前對類似優(yōu)化Mysql參數(shù)的具體步驟的文章有無了解，今天我在這里給大家再簡單的講講。感興趣的話就一起來看看正文部分吧，相信看完優(yōu)化Mysql參數(shù)的具體步驟你一定會有所收獲的。

站在用戶的角度思考問題，與客戶深入溝通，找到高坪網(wǎng)站設計與高坪網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設計與互聯(lián)網(wǎng)技術結合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：成都網(wǎng)站設計、做網(wǎng)站、企業(yè)官網(wǎng)、英文網(wǎng)站、手機端網(wǎng)站、網(wǎng)站推廣、域名與空間、網(wǎng)站空間、企業(yè)郵箱。業(yè)務覆蓋高坪地區(qū)。

一、優(yōu)化的配置文件

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.

二、參數(shù)解釋查看

max_connections = 1000       #客戶端連接數(shù)
max_connect_errors = 6000     #錯誤連接數(shù)
