MySQL安装
sudo wget https://cdn.mysql.com/archives/mysql-8.0/mysql-server_8.0.31-1ubuntu20.04_amd64.deb-bundle.tar下载MySQL文件。
sudo mkdir /mysql8创建目录。
sudo tar -xf mysql-server_8.0.31-1ubuntu20.04_amd64.deb-bundle.tar -C /mysql8进行解压。
需要使用到的安装命令如下：
sudo dpkg -i /mysql8/mysql-community-client-plugins_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-client-core_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-common_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-client_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/libmysqlclient21_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/libmysqlclient-dev_8.0.31-1ubuntu20.04_amd64.deb
sudo apt install -y libmecab2
sudo dpkg -i /mysql8/mysql-community-server-core_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-client_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-server_8.0.31-1ubuntu20.04_amd64.deb
需要输入密码
接下来就是上边命令图文安装步骤：
sudo dpkg -i /mysql8/mysql-community-client-plugins_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-client-core_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-common_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-client_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/libmysqlclient21_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/libmysqlclient-dev_8.0.31-1ubuntu20.04_amd64.deb
sudo apt install -y libmecab2
sudo dpkg -i /mysql8/mysql-community-server-core_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-client_8.0.31-1ubuntu20.04_amd64.deb
sudo dpkg -i /mysql8/mysql-community-server_8.0.31-1ubuntu20.04_amd64.deb就提示输入密码。
输入密码之后，需要用↓选中ok按回车键。
之后再次输入密码。
然后按下→选中<ok>再次按下回车键。
然后按下→选中<ok>按下回车键。
执行完成如下图：
sudo systemctl start mysql进行启动，systemctl status mysql可以看到状态是active (running)。
