某部署環境，因網絡限制無法直接訪問外網，所以只能手動下載安裝包方式進行mysql安裝。參考文章中仍有使用apt-get命令安裝依賴的部分，所以補充部分缺失依賴的離線安裝過程。
操作系統版本：
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial一 mysql下載
mysql官網-->download-->社區版，https://dev.mysql.com/downloads/mysql/，選擇對應操作系統版本的mysql安裝文件，如下，
下載mysql-server_8.0.11-1ubuntu16.04_amd64.deb-bundle.tar，完成后上傳至安裝機器。
tar -xf mysql-server_5.7.22-1ubuntu16.04_amd64.deb-bundle.tar命令解壓，得到如下安裝包：
-

依次執行下面命令進行安裝：
-
sudo dpkg -i mysql-common_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg-preconfigure mysql-community-server_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i libmysqlclient20_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i libmysqlclient-dev_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i libmysqld-dev_5.7.22-1ubuntu16.04_amd64.deb
-
-
sudo dpkg -i libc6_2.19-0ubuntu6_amd64.deb
-
sudo dpkg -i libaio1_0.3.110-2_amd64.deb
-
-
sudo dpkg -i mysql-community-client_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i mysql-client_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i mysql-common_5.7.22-1ubuntu16.04_amd64.deb
-
sudo dpkg -i libmecab2_0.996-1.2ubuntu1_amd64.deb
-
sudo dpkg -i mysql-community-server_5.7.22-1ubuntu16.04_amd64.deb
libc6_2.19-0ubuntu6_amd64.deb libaio1_0.3.110-2_amd64.deb libmecab2_0.996-1.2ubuntu1_amd64.deb
是安裝過程中依賴的包，這個根據實際安裝環境不同可能會有不同的錯誤提示，只要按照錯誤日志提示，下載依賴包，並使用dpkg -i命令執行安裝就可以解決。依賴包的下載，可在https://pkgs.org/上尋找，選擇自己的系統版本即可。以libaio1為例：
缺失依賴包提示日志：

mysql server安裝過程中會提示輸入root用戶密碼，待所有安裝完成后，使用命令登陸即可。如密碼設置為123456
