linuxmint安装MySQL

因为近来的工作需每天记录相关数据，本以为OFFICE能够胜任，单因为数据量太大，光是读入就已经很耗时间了，所以我决定使用数据库来解决。因为在学习读书时只接触使用过MySQL，所以就用它了！

1、安装很简单，直接键入

    sudo apt-get install mysql-server

安装完毕。

2、ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)

没想到遇到这种问题，不过网上立马可以搜索到解决办法。

    切换为root，键入

    cat /etc/mysql/debian.cnf

    显示为：

# Automatically generated for Debian scripts. DO NOT TOUCH!

[client]

host     = localhost

user     = debian-sys-maint

password = NHejdVGMEguIzjgg

socket   = /var/run/mysqld/mysqld.sock

[mysql_upgrade]

host     = localhost

user     = debian-sys-maint

password = NHejdVGMEguIzjgg

socket   = /var/run/mysqld/mysqld.sock

basedir  = /usr

只有将两项password的密码改为自己想要的密码，保存推出即可。

3、成功登陆

mysql -u root -p

Enter password:
