在Ubuntu14.04下离线安装MySQL 5.7.19所需的两个依赖包

简介：
本教程详解了如何在Ubuntu 14.04系统中不接入互联网的情况下，手动安装MySQL 5.7.19所必需的两个关键依赖包。 从MySQL官网下载了mysql-server_5.7.21-1ubuntu14.04_amd64.deb-bundle.tar后，在离线环境中进行安装。首先解压该安装包，会得到总共包含的11个依赖包，并按照顺序依次使用`sudo dpkg -i`命令来逐一安装这些包。 在尝试安装mysql-community-client_5.7.21-1ubuntu14.04_amd64.deb时遇到了如下问题： ``` dpkg: dependency problems prevent configuration of mysql-community-client: mysql-community-client depends on libaio1 (>= 0.3.93); however: Package libaio1 is not installed. ``` 接着尝试安装mysql-community-server_5.7.21-1ubuntu14.04_amd64.deb时，同样遇到了依赖问题： ``` dpkg: dependency problems prevent configuration of mysql-community-server: mysql-community-server depends on libmecab2 (>= 0.996-1.1); however: Package libmecab2 is not installed. ``` 附上正确的安装顺序如下： 1. `mysql-common_5.7.21-1ubuntu14.04_amd64.deb` 2. `libmysqlclient20_5.7.21-1ubuntu14.04_amd64.deb` 3. `libmysqlclient-dev_5.7.21-1ubuntu14.04_amd64.deb` 4. `libmysqld-dev_5.7.21-1ubuntu14.04_amd64.deb` 5. `libaio1_0.3.109-4_amd64.deb`（在第5步安装） 6. `mysql-community-client_5.7.21-1ubuntu14.04_amd64.deb` 7. `mysql-client_5.7.21-1ubuntu14.04_amd64.deb` 8. `mysql-community-source_5.7.21-1ubuntu14.04_amd64.deb` 9. `libmecab2_0.996-1.1_amd64.deb`（在第9步安装） 10. `mysql-community-server_5.7.21-1ubuntu14.04_amd64.deb` 按照上述顺序正确安装缺失的依赖包，可以解决遇到的问题。
