思考,总结

1.

imooc 安装MySQL:Ubuntu

2.

yum remove mariadb-libs.x86_64

cd /tmp/

wget https://repo.mysql.com/mysql57-community-release-e17-8.noarch.rpm

wget http://repo.mysql.com/mysql-community-release-e17-5.noarch.rpm

启动pycharm su 输入密码 cd /tmp/mozilla_linjing0/pycharm-2018.3.1/bin

apt install + 名称 #安装应用 apt autoremove +名称 #删除应用

3.

sudo apt-get update

sudo apt-get -y install mysql-server mysql-client

rpm -qa grep mysql-server
dpkg –list grep mysql

sudo apt-get remove mysql-*

dpkg -l grep ^rc awk ‘{print $2}’ sudo xargs dpkg -P

apt-get autoremove mysql* –purge

rpm -qa grep -i mysql

yum remove 文件名称

666

我不确定它是否会起作用,但试试这个。首先,您需要卸载与mysql相关的任何内容:

sudo apt-get purge mysql* sudo apt-get autoremove sudo apt-get autoclean 然后重要的一点,这个错误可能是因为你的发行版最近没有升级,或者至少没有正确解决冲突。接下来就是像以前一样升级它但不先删除它: 完全卸载mysql后,运行以下命令 sudo apt-get dist-upgrade

然后重新安装mysql

sudo apt-get install mysql-server
