ws2 ubuntu18.04安装mysql8.0+
1.下载最新的deb文件
wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.15-1_all.deb
2. 解压包
sudo dpkg -i mysql-apt-config_0.8.15-1_all.deb
安装过程中提示选择安装版本，默认安装的就是8.0版本，所以直接选择“OK”确认即可
3. 执行安装
sudo apt update
4. 安装mysql8.0 server
sudo apt install mysql-server
安装过程中会提示设置root密码。按照提示输入即可
输入之后会出现选择加密方式的提示界面，我在网上的教程中看到默认的mysql8.0的加密方式与ubuntu18.04 不兼容，所以选择5.x的加密方式；建议选择下边的那个
·Use Legacy Authentication Method·
5. 验证安装，输入命令
mysql -u root -p
错误记录
1. 签名无效 NO_PUBKEY xxxxxxxxxxxxxx
解决方式，设置可以并重新执行第三步命令
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 报错的key
eg:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7EA0A9C3F273FCD8

解决方案: INSTALLING MYSQL 8.0 UNDER WSL 2 AND UBUNTU
- 下载mysql.server.sh启动脚本
wget https://raw.githubusercontent.com/mysql/mysql-server/8.0/support-files/mysql.server.sh
- 修改该文件并复制到
/etc/init.d/目录下
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.
basedir=/usr
datadir=/var/lib/mysql
# Default value, in seconds, afterwhich the script should timeout waiting
# for server start.
# Value here is overriden by value in my.cnf.
# 0 means don‘t wait at all
# Negative numbers mean to wait indefinitely
service_startup_timeout=900
# Lock directory for RedHat / SuSE.
lockdir=‘/var/lock/subsys‘
lock_file_path="$lockdir/mysql"
# The following variables are only set for letting mysql.server find things.
# Set some defaults
mysqld_pid_file_path=/var/run/mysqld/mysqld.pid
if test -z "$basedir"
mv mysql.server.sh /etc/init.d/mysql
chomd +x /etc/init.d/mysql
- 启动MySQL
sudo service mysql start
sudo service mysql stop

mysql进入mysql命令行
刷新权限表
flush privileges;
- 查看
root用户和密码字段先将密码滞空
use mysql;

将旧密码滞空
update user set authentication_string=‘‘ where user=‘root‘;
- 删除
skip-grant-tables限制，重启mysql服务，重连mysql，并重置密码
