Hadoop2.5 64bit安装
1.系统环境说明
CentOS 7.0 x64 版本
192.168.1.7 master 192.168.1.8 slave 192.168.1.9 slave 192.168.1.10 slave
2.安装前的准备工作
2.1 关闭防火墙
# systemctl status firewalld.service --查看防火墙状态
# systemctl stop firewalld.service --关闭防火墙
# systemctl disable firewalld.service --永久关闭防火墙2.2 检查ssh安装情况，如果没有则安装ssh
# systemctl status sshd.service --查看ssh状态
# yum install openssh-server openssh-clients2.3 安装vim
# yum -y install vim2.4 设置静态ip地址
# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736BOOTPROTO="static" ONBOOT="yes" IPADDR0="192.168.1.7" PREFIX0="255.255.255.0" GATEWAY0="192.168.1.1" DNS1="61.147.37.1" DNS2="101.226.4.6"
2.5 修改host名称
# vim /etc/sysconfig/networkHOSTNAME=master
# vim /etc/hosts192.168.1.7 master 192.168.1.8 slave1 192.168.1.9 slave2 192.168.1.10 slave3
# hostnamectl set-hostname master (CentOS7 下原有的修改host方法无效了)2.6 创建hadoop用户
# useradd hadoop --创建用户名为hadoop的用户# passwd hadoop --为用户hadoop设置密码2.7 配置ssh无密钥登录
-----------下面是在master上面的操作
# su hadoop --切换到hadoop用户$ cd ~ --打开用户文件夹
$ ssh-keygen -t rsa -P '' --生成密码对，/home/hadoop/.ssh/id_rsa和/home/hadoop/.ssh/id_rsa.pub
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys --把id_rsa.pub追加到授权的key里面去
$ chmod 600 ~/.ssh/authorized_keys --修改权限
$ su --切换到root用户# vim /etc/ssh/sshd_config --修改ssh配置文件
RSAAuthentication yes #启用RSA认证
PubkeyAuthentication yes #启用公钥私钥配对认证方式
AuthorizedKeysFile .ssh/authorized_keys #公钥文件路径
# su hadoop --切换到hadoop用户
$ scp ~/.ssh/id_rsa.pub hadoop@192.168.1.8:~/ --把公钥复制所有的Slave机器上----------下面是在slave1上面的操作
# su hadoop --切换到hadoop用户
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys --追加到授权文件"authorized_keys"
$ chmod 600 ~/.ssh/authorized_keys --修改权限
$ su --切换回root用户 # vim /etc/ssh/sshd_config --修改ssh配置文件
RSAAuthentication yes #启用RSA认证
PubkeyAuthentication yes #启用公钥私钥配对认证方式
AuthorizedKeysFile .ssh/authorized_keys #公钥文件路径3.安装必须的软件
3.1 安装JDK
# rpm -ivh jdk-7u67-linux-x64.rpmPreparing... ##################################### [100%] 1:jdk ##################################### [100%] Unpacking JAR files... rt.jar... jsse.jar... charsets.jar... tools.jar... localedata.jar...
# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.7.0_67
export PATH=$PATH:$JAVA_HOME/bin
# source profile --修改生效3.2 安装其他必须软件
# yum install maven svn ncurses-devel gcc* lzo-devel zlib-devel autoconf automake libtool cmake openssl-devel3.3 安装ant
# tar zxvf apache-ant-1.9.4-bin.tar.gz# vim /etc/profile
export ANT_HOME=/usr/local/apache-ant-1.9.4
export PATH=$PATH:$ANT_HOME/bin3.4 安装findbugs
# tar zxvf findbugs-3.0.0.tar.gz# vim /etc/profile
export FINDBUGS_HOME=/usr/local/findbugs-3.0.0
export PATH=$PATH:$FINDBUGS_HOME/bin3.5 安装protobuf
# tar zxvf protobuf-2.5.0.tar.gz(必须是2.5.0版本的，不然编译hadoop的时候报错)
# cd protobuf-2.5.0
# ./configure --prefix=/usr/local
# make && make install4. 编译hadoop源码
# tar zxvf hadoop-2.5.0-src.tar.gz
# cd hadoop-2.5.0-src
# mvn package -Pdist,native,docs -DskipTests -Dtar4.1 maven中央仓库的配置(改成oschina,增加访问速度)
# vim /usr/share/mavem/conf/settings.xml
