CentOS7-64bit 编译 Hadoop-2.5.0，并分布式安装
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-clients
2.3 安装vim
# yum -y install vim
2.4 设置静态ip地址
# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
BOOTPROTO="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/network
HOSTNAME=master
# vim /etc/hosts
192.168.1.7 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.rpm

# 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-devel
3.3 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/bin
3.4 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/bin
3.5 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 install
4. 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 -Dtar
4.1 maven中央仓库的配置(改成oschina,增加访问速度)
# vim /usr/share/mavem/conf/settings.xml<mirrors> <mirror> <id>nexus-osc</id> <mirrorOf>*</mirrorOf> <name>Nexus osc</name> <url>http://maven.oschina.net/content/groups/public/</url> </mirror></mirrors><profiles> <profile> <id>jdk17</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.7</jdk> </activation> <properties> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion> </properties> <repositories> <repository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile></profiles>
