一、所需环境
操作系统：Ubuntu 20.04
数据库：MySQL 5.7.34
网络情况：内网服务器，无法访问互联网资源
二、提前下载所需以来及安装包
1、所需依赖包
（1）libmecab2
http://archive.ubuntu.com/ubuntu/pool/universe/m/mecab/libmecab2_0.996-1.2ubuntu1_amd64.deb
（2）libaio1
http://archive.ubuntu.com/ubuntu/pool/main/liba/libaio/libaio1_0.3.110-2_amd64.deb
（3）libtinfo5
http://archive.ubuntu.com/ubuntu/pool/universe/n/ncurses/libtinfo5_6.2-0ubuntu2_amd64.deb
2、下载MySQL安装包
演示所用版本：
https://cdn.mysql.com/archives/mysql-5.7/mysql-server_5.7.34-1ubuntu18.04_amd64.deb-bundle.tar
大家可以去官网下载自己需要的版本：
https://downloads.mysql.com/archives/community/
三、安装依赖，以及安装MySQL
1、将下载的依赖以及安装包上传到自己指定的文件夹（演示用/opt）
2、安装依赖包
sudo dpkg -i libmecab2_0.996-1.2ubuntu1_amd64.deb
sudo dpkg -i libaio1_0.3.110-2_amd64.deb
sudo dpkg -i libtinfo5_6.2-0ubuntu2_amd64.deb
3、安装MySQL
（1）解压安装包
sudo tar -xvf mysql-server_5.7.34-1ubuntu18.04_amd64.deb-bundle.tar解压后目录如下：
（2）安装MySQL
sudo dpkg -i mysql-common_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg-preconfigure mysql-community-server_5.7.34-1ubuntu18.04_amd64.deb //此步需要输入数据的root密码
sudo dpkg -i libmysqlclient20_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i libmysqlclient-dev_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i libmysqld-dev_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-community-client_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-client_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-common_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-community-server_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-server_5.7.34-1ubuntu18.04_amd64.deb
（3）验证MySQL的安装是否成功：
mysql -u root -p //输入密码
查看mysql状态：
sudo systemctl status mysql.service
四、MySQL配置
1、开启MySQL远程访问
（1）修改mysqld.cnf配置文件
sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf打开文件后将下面一行注释
#bind-address = 127.0.0.1（修改后）
（2）执行以下命令开启远程访问限制（注意：下面命令开启的IP是 192.168.0.1，如要开启所有的，用%代替IP）：
grant all privileges on *.* to 'root'@'192.168.0.1' identified by 'password' with grant option;然后再输入下面两行命令
flush privileges;
exit;2、防火墙开打开端口
sudo ufw allow 3306/tcp
注意：UFW防火墙开发 3306端口，UFW处于 Status: inactive 时（sudo ufw status verbose），可以不执行上面操作命令
