问题现象:
我的环境是xUbuntu 12.10下apt-get安装mysql,登陆无法登陆,报错信息这样描述:在用命令(sudo apt-get install mysql-server mysql-client)安装完.mysql服务即开始运行了.此时需要修改root密码,但经常会出现这么一种情况.'Access denied for user 'root'@'localhost' (using password: YES)' 或者其他致使无法登录mysql的情况。

解决方法:
1.打开/etc/mysql/debian.cnf文件,里面存储了相关的密码,我的文件信息如下

sudovi /etc/mysql/debian.cnf# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = debian-sys-maint
password = 6x1XG2B5p75WtFV2
socket = /var/run/mysqld/mysqld.sock

[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = 6x1XG2B5p75WtFV2
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

在[client]段有user=以及password=这两行,这就是通过apt-get安装mysql,系统给我们设置的mysql登录名和密码

2. 输入命令:
mysql -udebian-sys-maint -pdebian-sys- maint即debian.cnf中user=后面的内容.回车后会提示输入密码,,此时把password=后面的内容复制粘贴后回车即可进行mysql 控制台


3.进入控制台后.按以下步骤进行:
use mysql;update user set password=PASSWORD('新密码') where user='root';FLUSH PRIVILEGES;此时可以输入quit;退出后用root帐号登录,也可以继续其他操作.

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
