阿里云 Ubuntu18.0 安装 MySQL 8+

登录Linux服务器终端。
更新软件源并安装wget。

sudo apt update
sudo apt install wget

下载MySQL数据库安装包。

wget https://dev.mysql.com/get/mysql-apt-config_0.8.16-1_all.deb

说明如果没有安装wget，需要先执行apt install wget安装wget。

使用deb包更新软件源。

sudo dpkg -i mysql-apt-config_0.8.16-1_all.deb

在弹出的对话框中选择MySQL Server & Cluster (Currently selected: mysql-8.0)，然后选择Ok。

提示信息：

Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

从 MySQL APT 仓库更新包信息：

sudo apt update
sudo apt-cache policy mysql-server

或者使用提示有错使用这个更新

$ sudo apt-get update

根据获取到的安装版本安装MySQL5.7，安装过程中需设置root用户密码，请将密码记录并妥善保存。

sudo apt install -f mysql-client=5.7.32-1ubuntu18.04 mysql-community-server=5.7.32-1ubuntu18.04 mysql-server=5.7.32-1ubuntu18.04

配置MySQL数据库。

设置常规化安全。

sudo mysql_secure_installation

请根据提示信息设置，如下所示：

Enter current password for root (enter for none): <Enter password>
VALIDATE PASSWORD PLUGIN 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 plugin? 

Press y|Y for Yes, any other key for No: Y 

There are three levels of password validation policy: 

LOW    Length >= 8 
MEDIUM Length >= 8, numeric, mixed case, and special characters 
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                 

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 
Using existing password for root. 
Estimated strength of the password: 25  
Change the password for root ? ((Press y|Y for Yes, any other key for No) : d
Remove anonymous users? [Y/n] Y 
Disallow root login remotely? [Y/n] Y 
Remove test database and access to it? [Y/n] Y 
Reload privilege tables now? [Y/n] Y

开启远程访问。
编辑MySQL数据库的配置文件。

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

按I键，将bind-address的值修改为0.0.0.0。
按Esc键，输入:wq!保存并退出。
重启MySQL数据库服务使配置生效。

sudo systemctl restart mysql

MySQL 服务器在安装完成之后自动启动，我们可以查看 MySQL 服务器的状态：

$ sudo service mysql status
