span 安裝包 dpkg exe it is bubuko orm 權限 div
新搭建的服務器,先在Ubuntu上安裝mariadb,後來由於很多權限問題,決定安裝Mysql,在卸載過程中由於未卸載幹凈,導致mysql重裝過程中出現了很多問題。
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).
通過閱讀錯誤信息可知,主要是因為依賴關系出現問題,主要思路是重建依賴關系,然後幹凈卸載,最後重裝。
首先,更新系統
sudo apt-get update
然後,修復安裝錯誤,會提示輸入mysql用戶名密碼
sudo apt-get --fix-broken install
然後,檢索mysql安裝包,並刪除檢索出的依賴包,然後是刪除/var/lib/mysql,最後重裝mysql。
下面我把檢索到的解決方法展示給大家:
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 commandsudo 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如下圖所示:
最後就是更新系統並重裝mysql
sudo apt-get update sudo apt-get install mysql-server mysql-client
總結:
整體思路還是重建依賴關系,幹凈卸載,更新安裝。希望對遇到相同問題不知所措的小夥伴有所啟發、幫助。謝謝。
