ubuntu安装mysql没有让我设置密码
终端输入: sudo cat /etc/mysql/debian.cnf

显示内容:

[client]
host = localhost
user = debian-sys-maint
password = PGBiNPneSGXRlayQ
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = PGBiNPneSGXRlayQ
socket = /var/run/mysqld/mysqld.sock

其中有user和password可以用来登录,登录后再修改密码;

终端输入:mysql -u debian-sys-maint -p ,再输入密码后,进入mysql中

mysql>

在mysql客户端中输入依次输入以下内容:

mysql> show databases;
mysql> use mysql;
mysql> update user set authentication_string=PASSWORD("root") where user="root";

mysql> update user set plugin="mysql_native_password";
mysql> flush privileges;

其中PASSWORD后面的root可以为其他自定义的密码,

使用新密码登录mysql:mysql -u root -p
