[Centos-7.repo](http://mirrors.aliyun.com/repo/Centos-7.repo)\n 并上传到`/tmp`，进入到`/tmp`\n- 备份并且替换系统的repo文件\n ``` bash\n \tcp Centos-7.repo /etc/yum.repos.d/ \n\tcd /etc/yum.repos.d/ \n\tmv CentOS-Base.repo CentOS-Base.repo.bak \n\tmv Centos-7.repo CentOS-Base.repo\n\t ```\n- 将`nn1`上的`CentOS-Base.repo`拷贝到其他主机\n ```bash\n scp /etc/yum.repos.d/CentOS-Base.repo root@nn2:/etc/yum.repos.d\n

/etc/yum.repos.d/CentOS-Base.repo root@s3:/etc/yum.repos.d\n ```\n- 执行yum源更新命令\n ```bash\n\t yum clean all\n\t yum makecache \n\t yum update -y \n\t```\n- 安装常用软件\n ```bash\n yum install -y openssh-server vim gcc gcc-c++ glibc-headers bzip2-devel lzo-devel curl wget openssh-clients zlib-devel autoconf automake cmake libtool openssl-devel fuse-devel snappy-devel telnet unzip zip net-tools.x86_64 firewalld systemd ntp unrar bzip2\n ```\n### JDK安装\n>注意需要在六台机器依次执行\n- 上传到`/tmp`目录下，安装\n ```bash\n cd /tmp\n rpm -ivh jdk-8u144-linux-x64.rpm\n ```\n- 配置环境变量\n ```bash\n ln -s /usr/java/jdk1.8.0_144/ /usr/java/jdk1.8\n echo 'export JAVA_HOME=/usr/java/jdk1.8' >> /etc/profile.d/myEnv.sh \n echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /etc/profile.d/myEnv.sh \n source /etc/profile \n java -version\n ```\n### 修改主机名和主机名映射\n\n```bash\nvim /etc/hostname\n```\n6台机器分别为nn1、nn2、nn3、s1、s2、s3\n\n```bash\nvim /etc/hosts\n```\n\n修改为\n```text\n192.168.1.30 nn1\n192.168.1.31

组用户切换到root，配置免密切换root\n- 修改/etc/pam.d/su配置\n ```bash\n sed -i 's/#auth\\t\\trequired\\tpam_wheel.so/auth\\t\\trequired\\tpam_wheel.so/g' '/etc/pam.d/su' \n sed -i 's/#auth\\t\\tsufficient\\tpam_wheel.so/auth\\t\\tsufficient\\tpam_wheel.so/g' '/etc/pam.d/su'\n ```\n- 修改/etc/login.defs文件\n ```bash\n echo \"SU_WHEEL_ONLY yes\" >> /etc/login.defs\n ```\n- 添加用户到管理员，禁止普通用户su 到 root\n ```bash\n #把hadoop用户加到wheel组里\n gpasswd -a hadoop wheel\n #查看wheel组里是否有hadoop用户\n cat /etc/group | grep wheel\n ```\n### 给hadoop用户，配置SSH密钥\n#### 配置hadoop用户ssh免密码登录到hadoop\n- 仅在`nn1`执行这段脚本命令即可\n 但是 `su - hadoop ` ,` mkdir ~/.ssh` 需要在其他主机执行一下\n ```bash\n #切换到hadoop用户 \n su - hadoop\n #生成ssh公私钥 \n ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''\n ssh-copy-id nn1\n ssh-copy-id nn2\n

配置hadoop用户ssh免密码登录到root\n- 同上\n ```bash\n ssh-copy-id root@nn1\n ssh-copy-id root@ nn2\n ssh-copy-id root@nn3\n ssh-copy-id root@s1\n ssh-copy-id root@s2\n ssh-copy-id root@s3\n scp
