deepin mysql安装

1.安装mysql
  更新仓库：sudo apt-get update
  安装：sudo apt-get install mysql-server mysql-client
  问题：安装mysql5.7的过程中无root密码设置提示直接安装完成结束
2.不知道密码状态下打开mysql
  查询mysql是否运行：sudo netstat -tap |grep mysql
  (有显示就表示已运行)
  备注：mysql 打开(service mysql start) 关闭(service mysql stop) 重启命令(service mysql restart)
  查询默认的用户名和密码：sudo cat /etc/mysql/debian.cnf
baiguo@baiguo-PC:~$ sudo cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host    = localhost
user    = debian-sys-maint
password = F64nKZ233QkzL8v9
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host    = localhost
user    = debian-sys-maint
password = F64nKZ233QkzL8v9
socket = /var/run/mysqld/mysqld.sock
备注：这样比较麻烦，无法复制密码，可以直接打开你的文件管理器，用管理员身份打开debian.cnf即可查看复制密码
利用默认账户进行登录：mysql -u debian-sys-maint -p(文件中的密码，与p之间不要有空格)
3.进入mysql修该密码
这句必须：update mysql.user set plugin="mysql_native_password" where user="root";
      设置root账户密码：update mysql.user set authentication_string=password('这里是你的密码') where user='root'and Host = 'localhost';
4.退出数据库
exit
重新启动数据库

sudo service mysql restart

用自己设置好的密码登录

mysql -u root -p

输入密码,成功登录,如下.

baiguo@baiguo-PC:~$ mysql -u root -p
Enter password:
