在linux下安装完成mysql，通过执行service mysql start 确保mysql是启动的。在终端执行sudo apt-get install mysql-workbench在线安装mysql-workbench。安装完成后执行mysql-workbench，启动图形界面，但是却无法连接。在终端执行mysql -u root 却能进入mysql，说明mysql服务器是启动的。需要执行命令 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';  再启动mysql-workbench 即可连接。
