0.若之前有装过mysql,需要先清除mysql相关的安装信息

apt-get remove mysql-server

apt-get autoremove mysql-server

apt-get remove mysql-common

rm /var/lib/mysql/ -R

rm /etc/mysql/ -R

apt-get autoremove mysql* --purge

apt-get remove apparmor

若win10系统本身就装过mysql,则先需要关闭win10的mysql服务.防止后续冲突

1.若是新装的WSL,则可以直接进行安装

查看可以安装的mysql版本

apt-cache show mysql-server

结果如下,可以看到,只有5.7版本

Description-en: MySQL database server (metapackage depending on the latest version)

This is an empty package that depends on the current "best" version of

mysql-server (currently mysql-server-5.7), as determined by the MySQL

maintainers. Install this package if in doubt about which MySQL

version you need. That will install the version recommended by the

package maintainers.

.

MySQL is a fast, stable and true multi-user, multi-threaded SQL database

server. SQL (Structured Query Language) is the most popular database query

language in the world. The main goals of MySQL are speed, robustness and

ease of use.

开始安装

apt install mysql-server-5.7

#等待安装完成即可

#启动mysql服务

service mysql start

#开始安全配置向导

mysql_secure_installation

#开始时会让你配置root账户的密码

#注意每项的选择yes和no,其中以下项选no,因为要用到root远程登录,其他好像都是yes.

#Disallow root login remotely? [Y/n] n

2.配置mysql.

因为win10系统有些人已经装过mysql了,端口号要改下,还有其他的配置

网上说的在/etc/mysql/my.cnf修改,可能因为版本不同,我是在/etc/mysql/mysql.conf.d/mysqld.cnf

root@SC-201905211111:/opt# vim /etc/mysql/mysql.conf.d/mysqld.cnf

#内容我只拿了这要修改的部分:1.port改为3307 2.增加character-set-server=utf8

skip-grant-tables这两行,分别是设置字符编码和跳过登录时权限检查(不设置这个跳过权限,在navicat连接这个数据库时,就是被阻止)

[mysqld]

#

# * Basic Settings

#

user = mysql

pid-file = /var/run/mysqld/mysqld.pid

socket = /var/run/mysqld/mysqld.sock

port = 3307

basedir = /usr

datadir = /var/lib/mysql

tmpdir = /tmp

lc-messages-dir = /usr/share/mysql

skip-external-locking

character-set-server=utf8

skip-grant-tables

3.开启root远程访问权限

#重启mysql

service mysql restart

#登录mysql

mysql -uroot -p

#其中123456改成你的root用户的密码

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;

mysql> flush privileges;

root@SC-201905211111:/opt# vim /etc/init.wsl

#! /bin/sh

/etc/init.d/ssh $1

/etc/init.d/mysql $1

~

5.navicat连接,注意端口改为3307即可.
