大数据架构:搭建CDH5.5.1分布式集群环境

yum install -y ntp gcc make lrzsz wget vim sysstat.x86_64 xinetd screen expect rsync bind-utils iotop dstat nethogs openssl-devel openssh-clients

1) 配置 /etc/hosts
  master 10.17.172.230
  node1 10.17.172.231
  node2 10.17.172.232
  node3 10.17.172.233
  node4 10.17.172.234
  node5 10.17.172.235
  node6 10.17.172.236
  node7 10.17.172.237


2) HOSTNAME
  vi /etc/sysconfig/network
    HOSTNAME=master
  hostname master
  service network restart

host一次配好,不要去改;如果非要改,相关服务都要重启, authorized_keys要处理, known_hosts要删除

3) 无密码SSH
在主节点上执行 ssh-keygen -t rsa 一路回车,生成无密码的密钥对。
将所有节点的公钥添加到认证文件中:
  cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
scp文件到所有datenode节点:
  scp ~/.ssh/authorized_keys root@node1:~/.ssh/
  scp ~/.ssh/authorized_keys root@node2:~/.ssh/
  scp ~/.ssh/authorized_keys root@node3:~/.ssh/
  scp ~/.ssh/authorized_keys root@node4:~/.ssh/
  scp ~/.ssh/authorized_keys root@node5:~/.ssh/
  scp ~/.ssh/authorized_keys root@node6:~/.ssh/
设置authorized_keys的访问权限:
  chmod 600 ~/.ssh/authorized_keys

4) 修改 history命令 的记录数量
  sed -i 's/^HISTSIZE=1000/HISTSIZE=10000/' /etc/profile
  source /etc/profile

5) 安装 JAVA
rpm -qa | grep java 检查是否安装 jdk
rpm -ivh jdk-7u80-linux-x64.rpm 安装jdk

vi /etc/profile
  JAVA_HOME=/usr/java/jdk1.7.0_80
  export PATH=$JAVA_HOME/bin:$PATH
  export JRE_HOME=${JAVA_HOME}/jre
  export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
source /etc/profile

6) 配置 防火墙
  service iptables stop # 暂时关闭

7) 关闭SELINUX
临时生效:
  setenforce 0
重启后永久生效:
  cat /etc/selinux/config | grep "SELINUX="

  vi /etc/selinux/config
    SELINUX=disabled

8) 时区
  vi /etc/sysconfig/clock
    ZONE=Asia/Shanghai
  rm /etc/localtime
  ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

9) 配置 NTP 节点
  yum -y install ntp ntpdate

  chkconfig ntpd on # 开机启动
  chkconfig --list ntpd # 2-5为on状态就代表成功

master机器:
ntpdate -u 103.226.213.30 # 同步一下时间
vi /etc/ntp.conf
  driftfile /var/lib/ntp/drift

  restrict 127.0.0.1
  restrict -6 ::1

  restrict default nomodify notrap
  restrict -6 default nomodify notrap

  server 103.226.213.30 prefer
  server 0.rhel.pool.ntp.org iburst
  server 1.rhel.pool.ntp.org iburst
  server 2.rhel.pool.ntp.org iburst
  server 3.rhel.pool.ntp.org iburst
  server 210.72.145.44 iburst
  server pool.ntp.org iburst
  server time.windows.com iburst
  server ntp.sjtu.edu.cn iburst
  server time.asia.apple.com iburst
  server clock.via.net ntp.nasa.gov iburst

  includefile /etc/ntp/crypto/pw
  keys /etc/ntp/keys

service ntpd start # 启动
ntpstat # 命令查看同步状态

所有子节点:
vi /etc/ntp.conf
  driftfile /var/lib/ntp/drift

  restrict 127.0.0.1
  restrict -6 ::1

  restrict default kod nomodify notrap nopeer noquery
  restrict -6 default kod nomodify notrap nopeer noquery

  server master

  includefile /etc/ntp/crypto/pw
  keys /etc/ntp/keys

ntpdate -u master
service ntpd start

10) MySQL
  rpm -qa | grep -i mysql
  rpm --nodeps -e mysql-libs-5.1.71-1.el6.x86_64

  cd /usr/local
  tar -zxvf mysql.tar.gz

  cp /data/install_tools/init_server_env/mysql/my.cnf /usr/local/mysql/
  cp /data/install_tools/init_server_env/mysql/shutdown_mysql.sh /usr/local/mysql/
  cp /data/install_tools/init_server_env/mysql/start_mysql.sh /usr/local/mysql/

# 创建数据库相应目录和设置目录权限
  mkdir -p /data/mysql-3306/{tmp,data}
  groupadd mysql
  useradd -r -g mysql mysql -s /sbin/nologin
  chmod 755 /usr/local/mysql/*.sh
  chown -R mysql:mysql /data/mysql-3306
  chown -R mysql:mysql /usr/local/mysql

##初始化mysql
  cd /usr/local/mysql
  scripts/mysql_install_db --user=mysql --defaults-file=/usr/local/mysql/my.cnf
  /usr/local/mysql/start_mysql.sh

  netstat -ant|grep ':3306'|grep 'LISTEN' # 确认 3306 端口可用

  /usr/local/mysql/bin/mysql -uroot -S /data/mysql-3306/mysqld.sock
  use mysql;
  delete from user where user='';
  grant all privileges on *.* to root@'%' identified by 'qweasdzxc';
  update user set password=password('qweasdzxc') where user='root';
  grant select,insert,update,EXECUTE,lock tables on *.* to loguser@'%' identified by 'nagioscheck';
  grant usage on *.* to 'zabbixmysql'@'127.0.0.1' identified by 'zabbix123';
  flush privileges;
  select host,user,password from user;

首先要看本机MySQL的socket套接字文件在哪里:
  mysqld --verbose --help | grep socket

vi /etc/profile
  export PATH==$PATH:/usr/local/mysql/bin
source /etc/profile

 

11)安装CM==================================================================================================================
1) 主节点解压安装
  解压 cloudera-manager-el6-cm5.5.1_x86_64.tar.gz 到 /opt/目录

2) 建立数据库
  cp /data/install_tools/mysql-connector-java-5.1.42.jar /opt/cm-5.5.1/share/cmf/lib/

  # 这个权限,应该要
  grant all privileges on *.* to scm@'%' identified by 'scm';
  flush privileges;

  数据库类型 数据库名称 -h数据库主机名 -u数据库用户名 -p数据库密码--scm-host cmserver主机名 scm scm scm
  /opt/cm-5.5.1/share/cmf/schema/scm_prepare_database.sh mysql cm -h127.0.0.1 -uroot -pqweasdzxc -P3306 --scm-host master scm scm scm


3) Agent配置
  vi /opt/cm-5.5.1/etc/cloudera-scm-agent/config.ini
  server_host=master

  同步Agent到其他节点
  scp -r root@master:/opt/cm-5.5.1/ /opt/

  在所有节点创建cloudera-scm用户
  userdel cloudera-scm
  useradd --system --home=/opt/cm-5.5.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

  准备Parcels,用以安装CDH5(主节点)
  cp /data/install_tools/CDH/* /opt/cloudera/parcel-repo/
  mv /opt/cloudera/parcel-repo/CDH-5.5.1-1.cdh5.5.1.p0.11-el6.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.5.1-1.cdh5.5.1.p0.11-el6.parcel.sha

启动:
  echo > /opt/cm-5.5.1/log/cloudera-scm-server/cloudera-scm-server.log
  echo > /opt/cm-5.5.1/log/cloudera-scm-agent/cloudera-scm-agent.log

主节点:
  /opt/cm-5.5.1/etc/init.d/cloudera-scm-server start
  tail -f /opt/cm-5.5.1/log/cloudera-scm-server/cloudera-scm-server.log
    2017-06-28 11:02:29,570 INFO WebServerImpl:org.mortbay.log: Started SelectChannelConnector@0.0.0.0:7180
    2017-06-28 11:02:29,570 INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.
  标志执行成功

所有节点(包括主节点): 最好先启动子节点,最后启动主节点
  /opt/cm-5.5.1/etc/init.d/cloudera-scm-agent start
  tail -n20 /opt/cm-5.5.1/log/cloudera-scm-agent/cloudera-scm-agent.log # log 里面有错应该是正常的
  DnsResolutionMonitor throttling_logger INFO Using java location: '/usr/java/jdk1.7.0_80/bin/java'.
应该是标志执行成功,不确认

4) CDH5的安装配置
http://master:7180/cmf/

初始化:
MySQL 建库:
  create database hive;
  create database oozie;
  create database amon;
  create database hue;

性能相关:
  echo 0 > /proc/sys/vm/swappiness
  echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

  echo "" >> /etc/sysctl.conf
  echo "vm.swappiness=0" >> /etc/sysctl.conf
  sysctl -p

  echo "" >> /etc/rc.local
  echo "echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag" >> /etc/rc.local

【群集设置 - 审核更改】页面时:
# 使用了MySql作为hive的元数据存储,hive默认没有带mysql的驱动
  cp /opt/cm-5.5.1/share/cmf/lib/mysql-connector-java-5.1.42.jar /opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/hive/lib/

【群集设置 - 首次运行 命令】页面时:
  cp /opt/cm-5.5.1/share/cmf/lib/mysql-connector-java-5.1.42.jar /var/lib/oozie/

========================================================================================================================
错误:
1) Heartbeating to master:7182 failed
由于在主节点上启动了Agent后,又将Agent scp到了其他节点上导致的,首次启动Agent,它会生成一个uuid。

mv /usr/bin/host /usr/bin/host.bak
rm -rf /opt/cm-5.5.1/lib/cloudera-scm-agent/uuid

卸载:
umount cm_processes

rpm -qa | grep cloudera
rpm -e cloudera-manager-daemons-5.5.1-1.cm551.p0.8.el6.x86_64

ps -ef | grep cmf | grep -v "grep" | awk '{print "kill -9 " $2}' | sh
