First installing raspbian

树莓派3b到手了，我用最原始的方法装系统（我烧录的是带桌面的树莓派系统），
就是不搞什么网线，直接接鼠标键盘和显示器去装（于是这块板插了四根线，电源、鼠标、键盘、显示器），
设置好wifi密码并且固定ip地址（右键可以设置，但它不会立刻生效，甚至下次打开填写的内容会变空白，所以设置好后要立刻重启），
然后设置开机CLI，开启ssh，设置locale和键盘语言（这些默认的都不正确，我改成亚洲上海和美国英语）。
全部搞完后把线全拔了，只剩下电源线（就是安卓数据线），不过ssh连不上，
后来才明白原来电源线不能用太差的，如果太差的话会导致红灯闪烁和熄灭系统启动失败，
最后我用手柄的数据线就可以正常ssh了（看到红灯长亮就是正常了）

Raspbian experience （2018-07-11）

最开始运行树莓派的时候跟qemu是不同的，日志很少，它会有一个提示和树莓派logo（可能是扩展容量），重启后树莓派就跟qemu差不多了，有很长的日志。
另外总是提示under-voltage detected（欠电压），可能跟我用的电源线（安卓数据线）有关。。。
不过跑起来很顺畅，跟桌面版的raspbian差不多流畅，图形界面下cpu用很少，发热也不是很严重（虽然我没实际测试过）
另外我要吐槽一下树莓派3b的HDMI口实在太紧了，如果不插紧的话根本没办法输出到显示器上。。。
所以插好之后可以整个板举起来，跟吃雪糕似得

mysql

  • Change root password
    https://blog.csdn.net/a791693310/article/details/80612573
    $ sudo apt-get install mysql-server
    $ sudo mysql -uroot
    mysql> USE mysql;
    mysql> UPDATE user SET password=PASSWORD('123456') WHERE user='root';
    mysql> UPDATE user SET plugin='mysql_native_password' WHERE user='root';
    mysql> FLUSH PRIVILEGES;
    mysql> exit;

  • Why change plugin to mysql_native_password
    http://www.pecmd.com/?id=48
    $ sudo mysql -u root -p // 然后任意输密码登录。

select Host,User,plugin from mysql.user where User='root';
看加密方式：plugin是unix_socket。
MariaDB [(none)]> update mysql.user set plugin='mysql_native_password'; #改加密方式
MariaDB [(none)]> update mysql.user set password=PASSWORD("newpassword") where User='root'; #设置新密码
MariaDB [(none)]> flush privileges; #刷新生效

  • Remote login ((Access denied for user ‘root’@’10.0.2.2’)
    https://blog.csdn.net/faryang/article/details/50788795
    修改/etc/mysql/my.cnf文件
    $ sudo nano /etc/mysql/my.cnf
    or
    $ sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf
    找到下面这行，并用#注释掉，
    bind-address = 127.0.0.1
    3.2登录mysql，输入下面命令

    mysql> grant all privileges on *.* to root@"%" identified by "123456"; # 假设用户名密码是root，123456
    mysql> FLUSH PRIVILEGES;

  • mysql reading initial communication packet 解决方法
    https://yq.aliyun.com/ziliao/75075
    $ sudo nano /etc/mysql/my.cnf
    or
    $ sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf
    [mysqld] 段增加一个启动参数 skip-name-resolve
