LIN報文加密

『壹』 tp-lin路由器怎麼設置密碼認證類型選哪項

1．首先，我們打開電腦的瀏覽器，打開網頁上路由器的IP地址，然後登錄。

『貳』 2020-10-28 hdfs塊數據傳輸的數據加密

操作系統：CentOS linux release 7.4.1708 (Core)

軟體：jdk-8u201-linux-x64.tar.gz、hadoop-2.7.7.tar.gz

安裝：

登陸 192.168.1.17

hostnamectl set-hostname node1;mkdir /咐運opt/namenode;mkdir /opt/datanode

vi /etc/hosts

192.168.1.17  node1

192.168.1.18  node2

tar -zxvf jdk-8u201-linux-x64.tar.gz;mv jdk1.8.0_201/ /opt/jdk

tar -zxvf hadoop-2.7.7.tar.gz;mv hadoop-2.7.7/ /opt/hadoop

vi ~/.bashrc

export java_HOME=/opt/jdk

export HADOOP_HOME=/opt/hadoop

export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

source ~/.bashrc

------------------------------------

登陸 192.168.1.18

hostnamectl set-hostname node2;mkdir /opt/namenode;mkdir /opt/datanode

vi /etc/hosts

192.168.1.17  node1

192.168.1.18  node2

tar -zxvf jdk-8u201-linux-x64.tar.gz;mv jdk1.8.0_201/ /opt/jdk

tar -zxvf hadoop-2.7.7.tar.gz;mv hadoop-2.7.7/ /opt/hadoop

vi ~/.bashrc

export JAVA_HOME=/opt/jdk

export HADOOP_HOME=/opt/hadoop

export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

source ~/.bashrc

-----------------------------------

修改 core-site.xml 配置

<configuration>

    <property>

        <name>fs.defaultFS</name>

        <value>hdfs://192.168.1.17:9000</value>

    </property>

</configuration>

修改 hdfs-site.xml 配置

<configuration>

    <property>

        <name>dfs.replication</name>

 衡虛梁       <value>1</value>

    </property>

    <property>

        <name>dfs.namenode.name.dir</name>

        <value>file:///opt/namenode</value>

    </property>

    <property>

   譽乎     <name>dfs.datanode.data.dir</name>

        <value>file:///opt/datanode</value>

    </property>

    <property>

        <name>dfs.encrypt.data.transfer</name>

        <value>true</value>

    </property>

    <property>

        <name>dfs.encrypt.data.transfer.algorithm</name>

        <value>3des</value>

    </property>

    <property>

        <name>dfs.encrypt.data.transfer.cipher.suites</name>

        <value>AES/CTR/NoPadding</value>

    </property>

    <property>

        <name>dfs.block.access.token.enable</name>

        <value>true</value>

    </property>

</configuration>

-------------------------------

登陸 192.168.1.17

hadoop-daemon.sh start namenode;hadoop-daemon.sh start datanode

登陸 192.168.1.18

hadoop-daemon.sh start datanode

-------------------------------

測試

hadoop fs -mkdir  -p /user/linzw

hadoop fs -put anaconda-ks.cfg /user/linzw

備註：

如果不添加 dfs.block.access.token.enable = true，會出現如下報錯。添加該配置以後，可以正常寫入數據
