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:
