Hadoop2.7.7阿里雲安裝部署
阿新 • • 發佈：2021-01-23
阿里雲的網路環境不需要我們配置，如果是在自己電腦上的虛擬機器，虛擬機器的安裝步驟可以百度。這裡是單機版的安裝（也有叢集模式的介紹）
使用Xshell連線阿里雲主機，用命令將自己下載好的安裝包上傳到伺服器
# 先安裝程式，方便後面使用
[root@fda ~]# yum -y install lrzsz
# rz是上傳 sz 加檔名 是下載
# 如下命令回車會讓你選擇需要上傳的檔案
[root@fda ~]# rz
關閉防火牆
阿里雲的防火牆是關閉的，如果不是關閉的執行下面的相關命令
#檢視防火牆開啟狀態 [root@fda ~]# systemctl status firewalld #關閉防火牆 [root@fda ~]# systemctl stop firewalld #禁止開機啟動防火牆 [root@fda ~]# systemctl disable firewalld #開啟防火牆 [root@fda ~]# systemctl start firewalld #設定開機啟動防火牆 [root@fda ~]# systemctl enable firewalld #重啟防火牆 [root@fda ~]# systemctl restart firewalld
配置免密
修改hosts檔案，新增以下內容（自己有幾臺新增幾臺）
[root@fda ~]# vim /etc/hosts
# 新增以下內容
172.22.110.228 fda
配置SSH
#每臺機器先使用ssh執行以下，以在主目錄產生一個.ssh 資料夾 # ssh 後面跟主機名稱 [root@fda ~]# ssh fda #然後輸入no即可 #每臺機器均進入~/.ssh 目錄進行操作 [root@fda ~]# cd ~/.ssh #輸入以下命令，一路回車，用以產生公鑰和祕鑰 [root@fda .ssh]# ssh-keygen -t rsa -P '' #出現以下資訊說明生成成功 Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:6YO1h1emM9gcWvv9OT6ftHxLnjP9u8p25x1o30oq3No root@node01 The key's randomart image is: +---[RSA 2048]----+ | | | | | | | . | | S o o | | + O * . | | .

安裝 Java 環境
原JDK解除安裝
如果CentOS中已經安裝的有 JDK，可以先解除安裝當前 JDK，重新安裝新的 JDK。不解除安裝也可以正
常使⽤。如果想解除安裝，就看下⾯的程式碼即可
#查詢當前所有安裝的jdk版本 [root@fda ~]# rpm -qa|grep jdk #如果什麼都沒有展示說明沒有已安裝的jdk，則無需解除安裝，如果出現以下jdk，則可以解除安裝 copy-jdk-configs-2.2-3.el7.noarch java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64 java-1.8.0-openjdk-headless-1.8.0.131-11.b12.el7.x86_64 #解除安裝jdk，使用下面的方法解除安裝即可 [root@fda ~]# yum -y remove copy-jdk-configs-2.2-3.el7.noarch #再次查詢當前所有安裝的jdk版本 [root@fda ~]# rpm -qa|grep jdk
#在主節點上建立指定目錄
[root@fda ~]# mkdir -p /opt/module/Java
[root@fda ~]# mkdir -p /opt/module/Hadoop
#進入到Java目錄
[root@fda ~]# cd /opt/module/Java
#使用rz命令從windows主機上傳jdk壓縮包到主機上
[root@fda Java]# rz
#解壓到當前目錄
[root@fda Java]# tar -zxvf jdk-8u181-linux-x64.tar.gz
#配置環境變數
[root@fda Java]# vim /etc/profile
#在該檔案後面追加一下內容
export JAVA_HOME=/opt/module/Java/jdk1.8.0_181
export JRE_HOME=/opt/module/Java/jdk1.8.0_181/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/rt.jar
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
#使剛才的設定生效
[root@fda Java]# source /etc/profile
#檢測是否配置成功
[root@fda jdk1.8.0_181]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
安裝 Hadoop 環境
上傳檔案到伺服器
#上傳
[root@fda ~]# cd /opt/module/Hadoop
[root@fda Hadoop]# rz
#解壓
[root@fda Hadoop]# tar -zxvf hadoop-2.7.7.tar.gz
建立相應⽬錄：建立⽬錄是為了配置的時候知道誰與誰對應。其實可以不建立，Hadoop 會⾃動建立
#進入hadoop-2.7.7主目錄
[root@fda Hadoop]# cd hadoop-2.7.7
#建立以下目錄，以備後用
[root@fda hadoop-2.7.7]# mkdir tmp
[root@fda hadoop-2.7.7]# mkdir logs
[root@fda hadoop-2.7.7]# mkdir -p dfs/name
[root@fda hadoop-2.7.7]# mkdir -p dfs/data
[root@fda hadoop-2.7.7]# mkdir -p dfs/namesecondary
修改配置⽂件：在 Hadoop 中有以下配置⽂件需要做修改
指令碼的配置
[root@fda hadoop-2.7.7]# vim etc/hadoop/hadoop-env.sh
#修改JAVA_HOME為以下內容，否則容易出現Hadoop無法啟動問題
export JAVA_HOME=/opt/module/Java/jdk1.8.0_181
[root@fda hadoop-2.7.7]# vim etc/hadoop/yarn-env.sh
#修改JAVA_HOME為以下內容
export JAVA_HOME=/opt/module/Java/jdk1.8.0_181
[root@fda hadoop-2.7.7]# vim etc/hadoop/mapred-env.sh
#修改JAVA_HOME為以下內容：
export JAVA_HOME=/opt/module/Java/jdk1.8.0_181
