> 笔者这里zookeeper安装的时候选择的默认，因此只安装了一个zookeeper，但个人感觉后期应该需要增加zookeeper的界面数量

## 下面开始说安装的注事事项 ##

*  1、配置环境要符合要求，要纯净的系统环境

# 笔者环境
    # CM env
    192.168.1.137 cdh01.aniu.so CentOS6.9 16G Memory 100G LVM卷 （Manger 节点）
    192.168.1.148 cdh02.aniu.so CentOS6.9 4G Memory 70G LVM卷
    192.168.1.149 cdh03.aniu.so CentOS6.9 4G Memory 70G LVM卷
    192.168.1.150 cdh04.aniu.so CentOS6.9 4G Memory 70G LVM卷
    
    建议小白参考笔者的环境配置，主机名可以自定义
    
    #对四个节点的系统进行更新，安装开发工具包
    yum update -y && yum -y groupinstall "Development Tools"

*  2、关闭防火墙、禁用Selinux

# 关闭防火墙
    /etc/init.d/iptables stop && /etc/init.d/ip6tables stop
    chkconfig iptables off && chkconfig ip6tables off
    
    # 建议采用修改内核参数的方式关闭ip6tables 
    vim /etc/modprobe.d/dist.conf # 编辑此文件，在最后加入：
    
    # Disable ipv6
    alias net-pf-10 off
    alias ipv6 off
    
    # 禁用selinux
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
    setenforce 0  # 不重启临时生效

*  3、内核参数调整

# 内存参数调整
    sysctl -w vm.swappiness=10 或者 编辑vim /etc/sysctl.conf，在最后加入：
    
    vm.swappiness = 10
    
    编辑启动项vim /etc/rc.local,最后加入：
    echo never > /sys/kernel/mm/transparent_hugepage/defrag 
    echo never > /sys/kernel/mm/transparent_hugepage/enabled

> 注：上面所有操作在所有节点都需要执行

*  4、所有节点间配置免密认证

# CM节点执行
    ssh-keygen -t rsa -b 2048 # 有确认提示，一直按回车即可
    cat ~/.ssh/id_rsa.pub > ~/.ssh/authorized_keys
    chmod 600 ~/.ssh/authorized_keys
    # 笔者 hosts.conf
    # CM node
    192.168.1.137 cdh01.aniu.so
    192.168.1.148 cdh02.aniu.so
    192.168.1.149 cdh03.aniu.so
    192.168.1.150 cdh04.aniu.so
    
    # 同步密钥
    for ip in $(awk '{print $1}' hosts.conf );do scp ~/.ssh/authorized_keys root@$ip:/root/.ssh ;done
    或者使用
    ssh-copy-id root@cdh01.aniu.so
    ssh-copy-id root@cdh02.aniu.so
    ssh-copy-id root@cdh03.aniu.so
    ssh-copy-id root@cdh04.aniu.so
    # 上面操作也需要在所有节点执行

*  5、使用cloudera-manger repo安装CM

# 在CM节点执行
    wget http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/cloudera-manager.repo -P /etc/yum.repos.d
    wget https://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/cloudera-cdh5.repo -P /etc/yum.repos.d
    # 
    yum clean all && yum makecache # 建议执行不强制
    yum install oracle-j2sdk1.7 -y
    yum install cloudera-manager-daemons cloudera-manager-server -y
    
    # 在其他节点执行
    wget http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/cloudera-manager.repo -P /etc/yum.repos.d
    yum install oracle-j2sdk1.7 -y
    
    # 配置JAVA_HOME
    编辑vim /etc/profile
    export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera
    export PATH=$JAVA_HOME/bin:$PATH
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    保存退出执行：
    source /etc/profile 使更改的环境变量生效
    
    # 在所有节点执行配置JAVA_HOME的操作

*  6、CM节点安装数据库，或使用已有的数据

# 笔者使用mysql57-community.repo,安装的mysql
    [mysql57-community]
    name=MySQL 5.7 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
    enabled=1
    gpgcheck=0
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
    #
    yum install mysql-community-embedded  mysql-community-server  mysql-community-devel mysql-community-client -y
    
    # 笔者my.cnf
    [root@cdh01 yum.repos.d]# cat /etc/my.cnf
    [client]
    port        = 3306
    socket      = /var/lib/mysql/mysql.sock
    
    [mysqld]

    expire_logs_days = 10
    early-plugin-load = ""
    
    default_storage_engine          = InnoDB
    innodb_file_per_table           = 1
    innodb_data_home_dir            = /opt/mysql

    innodb_buffer_pool_size         = 16M
    innodb_log_file_size            = 5M
    innodb_log_buffer_size          = 8M
    innodb_flush_log_at_trx_commit  = 1
    innodb_lock_wait_timeout        = 50
    innodb_log_files_in_group       = 3 
    innodb_buffer_pool_size         = 12G
    innodb_log_file_size            = 512M
    innodb_log_buffer_size          = 256M
    innodb_flush_log_at_trx_commit  = 2
    innodb_lock_wait_timeout        = 150
    innodb_open_files               = 600
    innodb_max_dirty_pages_pct      = 50
    innodb_file_per_table           = 1
    
    [mysqldump]
    quick
    max_allowed_packet = 16M
    
    [mysql]
    no-auto-rehash
    
    [myisamchk]
    key_buffer_size = 20M
    sort_buffer_size = 20M
    read_buffer = 2M
    write_buffer = 2M
    
    [mysqlhotcopy]
    xinteractive-timeout
    
    symbolic-links=0
    slow_query_log
    long_query_time = 5
    slow_query_log_file = /var/log/mysql-slow.log
    log-error = /var/log/mysqld.log
    pid-file = /var/run/mysqld/mysqld.pid
    
    # 初始化mysql，并设置启动数据库设置root密码
    /usr/sbin/mysqld --initialize --user=mysql --socket=/var/lib/mysql/mysql.sock # 先执行
    mysql_secure_installation # 再执行
    
    # 创建CM启动用到的数据库
    mysql -u root -pAniuops123. -e "create database cmf DEFAULT CHARACTER SET utf8;"
    mysql -u root -pAniuops123. -e "GRANT ALL PRIVILEGES ON `cmf`.* TO 'cmf'@'localhost' IDENTIFIED BY 'Aniunas123.'";"

*  启动cloudera-scm-server，并配置parcel

# 生成db配置文件
    /usr/share/cmf/schema/scm_prepare_database.sh mysql cmf cmf Aniucmf123.
    
    # 启动cloudera-scm-server
    /etc/init.d/cloudera-scm-server start # 查看启动日志
    
    # 配置parcel离线
    cd /opt/cloudera/parcel-repo/ # 然后下载
    
    wget http://archive.cloudera.com/cdh5/parcels/latest/CDH-5.13.1-1.cdh5.13.1.p0.2-el6.parcel
    wget http://archive.cloudera.com/cdh5/parcels/latest/CDH-5.13.1-1.cdh5.13.1.p0.2-el6.parcel.sha1
    wget http://archive.cloudera.com/cdh5/parcels/latest/manifest.json
    
    # 注：读者根据cloudera当前CDH最新版本更改下载用到的URL
    mv CDH-5.13.1-1.cdh5.13.1.p0.2-el6.parcel.sha1 CDH-5.13.1-1.cdh5.13.1.p0.2-el6.parcel.sha # 强制执行、默认使用本地的parcels包，不更改sha1,cloudera-scm-server启动安装时会去cloudera官网找匹配的parcel安装包
    
    重启cloudera-scm-server，查看实时日志
    /etc/init.d/cloudera-scm-server restart
    tailf /var/log/cloudera-scm-server/cloudera-scm-server.log

*  通过CM管理界面安装CDH，注意事项

# CM server启动成功即可通过http://192.168.1.137:7180访问，默认账户密码：admin admin
    
    # **重点内容** 下面的话很重要：
    
    
    不要勾选：单用户模式 ，笔者在此模式下安装多次都没成功，有心人可以测试

*  能一次性安装成功的最好，安装不成功建议多试几次，对初始化完成的虚拟机进行快照操作，便于恢复
