如何安装Ubunt？
我是在子系统服务刚出来时就已经开启该服务(当时装的是kali),时间久远, 如何开启服务和安装子系统已经不方便截图, 且网上教程已近多如星辰,就不在赘言! 本人安装的是Ubuntu 18.04

Windows10开启Ubuntu子系统简易步骤
安装Ubuntu之补充
1.修改root账户密码: sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
2.切换为root用户(有些操作root账户权限才可以): su root
Password:
root@DESKTOP-R3SRO54:/home#
MySQL相关操作
( 一 ) 安装:
命令: sudo apt-get install mysql-server
注意: Ubuntu安装过程中不会出现让你设定密码的过程, 所以通过`mysql -u root -p 登录时(关于启动报错解决,请看下文!), 出现输入密码时,有两种处理方式:
- 方式1: 直接按Enter键即可(默认为空)!
- 方式2: 命令:
cd /etc/mysql/
vi debian.cnf
host = localhost
user = debian-sys-maint
#这是系统提供的方法
password = pSoUYT8SfB2R7sy2
socket = /var/run/mysqld/mysqld.sock
修改MySQL密码
#登入MySQL执行以下操作
- use mysql
- update mysql.user set authentication_string=password('自定义密码') where user='root';
- flush privileges;//刷新MySQL的系统权限相关表
关于端口3306修改以及win10访问的原因及方式
如果你windows10本身安装了MySQL服务, 则会使用3306端口,windows10端口是和子系统共用的, 所以为了能够在windows10系统内通过navicat或者cmd等方式连接子系统MySQL, 则必须选择更改其中一个服务端口号, 建议更改子系统中该服务端口号!
命令: cd /etc/mysql/mysql.conf.d/
root@DESKTOP-R3SRO54:/# cd /etc/mysql/mysql.conf.d
root@DESKTOP-R3SRO54:/etc/mysql/mysql.conf.d# ls
mysqld.cnf mysqld_safe_syslog.cnf
命令: vi mysqld.cnf #修改完成后重启MySQL服务
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
# 修改端口号
port = 9999
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
( 二 )启动:
注意: 启动方式暂时仅测试了Ubuntu, Debian!等未测试
命令: sudo service mysql start
注意: 可能会出现的错误: 【No directory, logging in with HOME=/】
- 解决方法
usermod -d /var/lib/mysql/ mysql
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
chown -R mysql:mysql /var/lib/mysql
#重启mysql即可
sudo service mysql restart
( 三 ) 查看状态、重启、停止
查看状态
命令: sudo service mysql status

( 四 ) windows10访问子系统MySQL
命令: mysql -h127.0.0.1 -P [你自定义的端口号] -u root -p
#注意端口P和密码p大小写的区别
C:\Users\anonymous>mysql -h127.0.0.1 -P 9999 -u root -p
Enter password: *********
