3、更新镜像源
sudo apt-get update
4、更新软件
sudo apt-get upgrade
参考文件
三、安装miniconda3
1、下载miniconda3
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
2、安装miniconda3
bash Miniconda3-latest-Linux-x86_64.sh
- 一直回车，知道问你是否接收协议，选yes
- 询问安装位置
Miniconda3 现在将安装到此位置： /home/cxl/miniconda3
- 按 ENTER 确认位置
- 按 CTRL-C 中止安装
- 或在下方指定不同的位置
- 询问是否要初始化
你希望安装程序初始化 Miniconda3
通过运行 conda init？ [是|否]
如果选中 No，需要手动初始化，将miniconda加入环境变量
3、检查miniconda3安装成功没有：
conda activate
报错：
错误原因：
~/.bashrc文件没有配置好，需要在 ~/.bashrc 文件的最后一行加上miniconda3的bin路径
export PATH=$PATH:/home/cxl/anaconda3/bin
启用新的文件
source ~/.bashrc
四、安装Mysql数据库
1、下载mysql
sudo apt-get install mysql-client-core-5.7
sudo apt-get install mysql-client-5.7
sudo apt-get install mysql-server-5.7
2、设置密码
使用client的user和password登录
sudo cat /etc/mysql/debian.cnf
mysql -u debian-sys-maint -p
update mysql.user set authentication_string=password('123456') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password";
flush privileges;
quit;
重启mysql，就可以用新密码登录了；
sudo service mysql restart;
mysql -u root -p
3、远程连接设置
编辑 mysqld.cnf 文件，注释掉 bind-address = 127.0.0.1
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
重启mysql服务
sudo service mysql restart
给root用户授权
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
五、windows pycharm连接wsl
1、pycharm – setting – project:XXX – python Interpreter
