错误在ubuntu16.04

Question

在这里安装MySQL服务器是我收到

Setting up mysql-server-5.7 (5.7.12-0ubuntu1.1) ... 
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details. 
invoke-rc.d: initscript mysql, action "start" failed. 
dpkg: error processing package mysql-server-5.7 (--configure): 
subprocess installed post-installation script returned error exit status 1 
dpkg: dependency problems prevent configuration of mysql-server: 
mysql-server depends on mysql-server-5.7; however: 
    Package mysql-server-5.7 is not configured yet. 

dpkg: error processing package mysql-server (--configure): 
dependency problems - leaving unconfigured 
Processing triggers for man-db (2.7.5-1) ... 
No apport report written because the error message indicates its a followup error from a previous failure. 
          Errors were encountered while processing: 
mysql-server-5.7 
mysql-server 
E: Sub-process /usr/bin/dpkg returned an error code (1) 

如在上面的代码2行表示以下指令后的错误，我得到

$ systemctl status mysql.service

我已经尝试重新安装它多次，但它总是显示相同的错误。什么可能是这个错误的原因？

Answer 1

吹扫删除所有MySQL软件包：

$ sudo apt-get remove --purge mysql* 

$ sudo apt-get autoremove --purge 

如果目录/ etc/MySQL的存在，上述的命令被执行，即使后，然后取出它：

$ sudo rm -rf /etc/mysql 

现在，首先all，安装包mysql-client：

$ sudo apt-get install mysql-client 

最后，安装mysql -c后的包mysql-server lient已成功安装：

$ sudo apt-get install mysql-server 

我试图在链接描述如下所有的解决方案，但没有工作！这是我能解决mysql服务器安装错误的唯一方法。
