个人笔记,问题较多

符号说明	[]	表示其中内容可以没有
su [root]	获取root权限
vi /etc/sudoers	1.点击I或Insert获得插入权限 2.在root ALL=(ALL) ALL行后面添加: usr ALL=(ALL)[NOPASSWD:]ALL 3.点击Esc, 输入 :wq! 保存. (此文件默认没有写入权限所以需要加!来写入)
exit	退出root权限
	将需要安装的软件拷贝到桌面
sudo tar -zxvf jdk...	解压
sudo mv jdk... /usr/local/java	将解压后的软件复制到相应路径, 同样执行操作hadoop, scala, spark
bash Ana... .sh -b	安装Anaconda, -b表示系统直接使用默认设置安装
sudo gedit ~/.bashrc	配置环境变量 #Hadoop Variables export JAVA_HOME= /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-3.b16.el6_9.x86_64 export HADOOP_HOME=/usr/local/hadoop export PATH=$PATH:$HADOOP_HOME/bin export PATH=$PATH:$HADOOP_HOME/sbin export HADOOP_MAPRED_HOME=$HADOOP_HOME export HADOOP_COMMON_HOME=$HADOOP_HOME export HADOOP_HDFS_HOME=$HADOOP_HOME export YARN_HOME=$HADOOP_HOME export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib" export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native:$JAVA_LIBRARY_PATH #Hadoop Variables   export PATH=${JAVA_HOME}/bin:${PATH} export HADOOP_CLASSPATH=${JAVA_HOME}/lib/tools.jar   export SCALA_HOME=/usr/local/scala export PATH=$PATH:$SCALA_HOME/bin   export SPARK_HOME=/usr/local/spark export PATH=$PATH:$SPARK_HOME/bin   export PATH=/home/hdusr/anaconda2/bin:$PATH #此行需修改   export ANACONDA_PATH=/home/hdusr/anaconda2 #此行需修改 export PYSPARK_DRIVER_PYTHON=$ANACONDA_PATH/bin/ipython export PYSPARK_PYTHON=$ANACONDA_PATH/bin/python
source ~/.bashrc	重新载入配置文件
sudo yum install openssh	安装ssh
ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa	'' 是两个单引号 产生SSH Key 进行后续身份验证
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys	将产生的Key放置到授权文件中
chmod 700 ~/.ssh	$ chmod 644 ~/.ssh/authorized_keys
只在master执行	$ cat ~/.ssh/id_dsa.pub | ssh hdusr@data1 'cat - >> ~/.ssh/authorized_keys'
sudo tail /var/log/secure -n 20	查看日志
sudo gedit /etc/sysconfig/network	修改主机名 HOSTNAME=新主机名
service iptables stop	关闭防火墙
sudo chkconfig iptables off	永久关闭防火墙
Hadoop设置	$sudo gedit /usr/local/hadoop/etc/hadoop/hadoop-env.sh export JAVA_HOME=${JAVA_HOME}修改为 export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-3.b16.el6_9.x86_64
	$sudo gedit /usr/local/hadoop/etc/hadoop/core-site.xml <configuration> <property>    <name>fs.default.name</name>    <value>hdfs://master:9000</value> </property> </configuration>
	$sudo gedit /usr/local/hadoop/etc/hadoop/yarn-site.xml <configuration> <!-- Site specific YARN configuration properties --> <property>    <name>yarn.nodemanager.aux-services</name>    <value>mapreduce_shuffle</value> </property> <property>    <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>    <value>org.apache.hadoop.mapred.ShuffleHandler</value> </property> <property>    <name>yarn.resourcemanager.resource-tracker.address</name>    <value>master:8025</value> </property> <property>    <name>yarn.resourcemanager.scheduler.address</name>    <value>master:8030</value> </property> <property>    <name>yarn.resourcemanager.address</name>    <value>master:8050</value> </property> </configuration>
	$sudo cp /usr/local/hadoop/etc/hadoop/mapred-site.xml.template /usr/local/hadoop/etc/hadoop/mapred-site.xml $sudo gedit /usr/local/hadoop/etc/hadoop/mapred-site.xml <configuration> <property>    <name>mapred.job.tracker</name>    <value>master:54311</value> </property> </configuration>

	$sudo mkdir -p /usr/local/hadoop/hadoop_data/hdfs/namenode 建立NameNode资料存储目录(master)
	$sudo mkdir -p /usr/local/hadoop/hadoop_data/hdfs/datanode 建立DataNode资料存储目录
	$sudo chown hdusr:hdusr -R /usr/local/hadoop/ 将hadoop目录拥有者改为hdusr
	$hadoop namenode -format 将HDFS进行格式化(此命令会删除HDFS中的所有资料)
	$ip addr  复制mac地址  “dhcp” $sudo gedit /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0" BOOTPROTO="static" HWADDR="00:0C:29:5C:30:F1" IPV6INIT="yes" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="e779e28b-2f28-44ee-a194-f2ec781860fb" IPADDR=192.168.179.140 NETMASK=255.255.255.0 GATEWAR=192.168.179.2 $ifconfig  查看本机ip确定修改成功

	$cd /usr/local/spark/conf/ $cp log4j.properties.template log4j.properties $sudo gedit log4j.properties INFO改为WARN 表示在启动pyspark时只显示警告信息
	sudo chown hdusr:hdusr /usr/local/spark/ 将spark目录拥有者改为hdusr
	复制虚拟机到data1修改完再复制data1到data2和data3,最后一步省略
	$sudo gedit /etc/passwd  (可不执行,更改开机显示的用户名) 最后一行hdusr:x:500:500:用户名:/home/hdusr:/bin/bash
	$sudo gedit /etc/sysconfig/network (此处修改需重启才能继续, 可最后再修改) 修改主机名   HOSTNAME=新主机名
	$ip addr $sudo gedit /etc/sysconfig/network-scripts/ifcfg-eth0 修改第一行, mac和ip $ifconfig
	$sudo gedit /usr/local/hadoop/etc/hadoop/hdfs-site.xml name改为data <property>    <name>dfs.datanode.data.dir</name>    <value> file:/usr/local/hadoop/hadoop_data/hdfs/datanode</value> </property>
	$ssh data1 $sudo rm -rf /usr/local/hadoop/hadoop_data/hdfs/ $mkdir -p /usr/local/hadoop/hadoop_data/hdfs/datanode
