安装步骤

1.安装MySQL

sudo apt-get update  #Get the latest software sources
sudo apt-get install mysql-server #安装mysql

启动与关闭MySQL

service mysql start  #启动MySQL
service mysql stop  #关闭MySQL

2.配置MySQL

开始配置：

sudo mysql_secure_installation


...
# 1.Ask whether to install the password plugin,我选择 No
VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?
Press y|Y for Yes, any other key for No: n

# 2.为root用户设置密码
Please set the password for root here.

New password: 

Re-enter new password: 
#2.1 The solution is detailed in the next section,解决bug
 ... Failed! Error: SET PASSWORD has no significance for user 'root'@'localhost' as the authentication method used doesn't store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.

# 2.2 解决bug后,重新设置密码
New password: 

Re-enter new password: 

#3.删除匿名用户,我选No
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : n

 ... skipping.

#4.禁止root管理员从远程登录,这里我选 No
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
 
 #5.删除test数据库并取消对它的访问权限, 我选 No
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
 
 #6.刷新授权表,让初始化后的设定立即生效, 选 Yes
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done! 

3.解决配置MySQL中的bug

解决报错Failed! Error: SET PASSWORD has no significance for user ‘root’@‘localhost’ as the authentication me

sudo mysql


ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password';

Completed as shown below,You can repeat the operation of changing the password in the previous section

4.安装可视化工具MySQL-workbench

命令行直接安装MySQL-workbench,安装不了

sudo apt-get install MySQL-workbench

安装包下载地址如下：https://dev.mysql.com/downloads/workbench/,Choose with native systems as wellMySQLDownload the version that matches the version,Since the system and version are Ubuntu20.04 LST 以及MySQL 8.0.29,Therefore, visualization tools are usedmysql-workbench-community_8.0.29-1ubuntu20.04_amd64.deb.on the native system vsMySQLThe version is not clear,You can query by referring to the following command line

sudo mysql


SELECT @@VERSION;

完成mysql-workbench版本下载后,终端进入下载目录,进行安装

sudo dpkg -i mysql-workbench-community_8.0.29-1ubuntu20.04_amd64.deb

If the dependency error shown in the figure below occurs
You can enter the following command to solve the problem,Then repeat the above installation command

sudo apt -f install

As in the above setup,允许rootAdministrators connect from remote,So there is in the interfaceLocal instance 3306,Click to enter and enter the password to enter the graphical management interface

The connection is successful to startMySQLThe graphical interface operation is used.
