新搭建的服务器,先在Ubuntu上安装mariadb,后来由于很多权限问题,决定安装Mysql,在卸载过程中由于未卸载干净,导致mysql重装过程中出现了很多问题。
Reading package lists...Done Building dependency tree Reading state information ... Done mysql-server is already the newest version(5.7.21-0ubuntu0.16.04.1). You might want to run ‘apt-get -f install‘ to correct these: The following packages have unmet dependencies: mysql-server: depends: mysql-server-5.7 but it is not going to be installed E: Unmet dependencies.Try ‘apt-get -f install‘ with no packages(or specify a solution).
通过阅读错误信息可知,主要是因为依赖关系出现问题,主要思路是重建依赖关系,然后干净卸载,最后重装。
首先,更新系统
sudo apt-get update
然后,修复安装错误,会提示输入mysql用户名密码
sudo apt-get --fix-broken install
然后,检索mysql安装包,并删除检索出的依赖包,然后是删除/var/lib/mysql,最后重装mysql。
下面我把检索到的解决方法展示给大家:
We excute the following commands to solve the above problem: 1.Get the list of MySQL packages installed on the system by executing the command sudo dpkg -l grep mysql 2.Remove the packages shown above by executing the command sudo apt-get --purge autoremove <packages from the step 1> 3. Delete /var/lib/mysql 4.Try to install mysql again.It should solve your problem.
第二步中的packages如下图所示:
最后就是更新系统并重装mysql
sudo apt-get update sudo apt-get install mysql-server mysql-client
总结:
整体思路还是重建依赖关系,干净卸载,更新安装。希望对遇到相同问题不知所措的小伙伴有所启发、帮助。谢谢。
