package main

import "fmt"

func main() {
   fmt.Println("Hello, 大球Cat!")
}

go run cat.go
go build cat.go

wget https://golang.google.cn/dl/go1.15.linux-arm64.tar.gz
tar -C /usr/local -xzf go1.15.linux-arm64.tar.gz
export PATH=$PATH:/usr/local/go/bin

可以交叉编译

set GOOS=linux
set GOARCH=arm64

密钥还有很多种存储方式，比如java形式的base64，还有c#形式的xml等
私钥也可以用来加密，公钥解密，需要用到BouncyCastle.Crypto.dll这个库

IBufferedCipher c = CipherUtilities.GetCipher("RSA/ECB/PKCS1Padding");
c.Init(false, PublicKeyFactory.CreateKey(Convert.FromBase64String(pubKey)));
byte[] wb = c.DoFinal(buf, 0, l);

公钥解密的栗子，用的是base64格式的密钥

原来也不是直接可以挂载的，还要装点儿东西
sudo apt-get install exfat-fuse
然后就可以挂啦
sudo mount /dev/sda /mnt/usb_flash

JDK要配好java -version

vi /home/user/hbase/conf/hbase-env.sh

export JAVA_HOME=/home/user/miku/jdk
export HBASE_MANAGES_ZK=true

vi /home/user/hbase/conf/hbase-site.xml

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>file:/home/user/miku/data</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>file:/home/user/miku/data/zookeeper</value>
    </property>
</configuration>

/home/user/hbase/bin/start-hbase.sh # stop-hbase.sh 停止
hbase shell

status
create 'table1','field1'
t1 = get_table('table1')
t1.put 'row1', 'field1:qualifier1', 'value1'
t1.scan
