CentOS 7.1上Cloudera Manager 5.6的部署与故障预防指南

---------------------------------------------------------------------------------------by雷鸣 318808830@qq.com
各主机配好网络static ipaddr netmask gateway，
DNS1=192.168.11.246
DNS2=8.8.8.8
配好/etc/hosts 
192.168.11.41 centos1
192.168.11.42 centos2
192.168.11.43 centos3

各主机安装 Oracle JDK  jdk-8u60-linux-x64.tar.gz     192.168.11.48上有对应资源
本例对应java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

所有节点下载包：cloudera-manager-centos7-cm5.6.0_x86_64.tar.gz   CDH-5.6.0-1.cdh5.6.0.p0.45-el7.parcel
192.168.11.48上有对应资源
mkdir /opt/cloudera-manager
manager server 节点解压cm的tar.gz包
tar xzf cloudera-manager*.tar.gz -C /opt/cloudera-manager

all节点 Create Users
useradd --system --home=/opt/cloudera-manager/cm-5.6.0/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
mkdir -p /opt/cloudera/parcel-repo 
chown cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo

manager server节点
/opt/cloudera/parcel-repo/CDH-5.6.0-1.cdh5.6.0.p0.45-el7.parcel 等3文件备好
把下载的.parcel文件和manifest.json文件拷贝到/opt/cloudera/parcel-repo/文件夹下
新建文件命名为：CDH-5.6.0-1.cdh5.6.0.p0.45-el7.parcel.sha
打开manifest.json文件查看CDH-5.6.0-1.cdh5.6.0.p0.45-el7.parcel对应的编号，并拷贝到CDH-5.6.0-1.cdh5.6.0.p0.45-el7.parcel.sha文件中

mkdir /var/log/cloudera-scm-server 
mkdir /var/lib/cloudera-scm-server
chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-server
chown cloudera-scm:cloudera-scm /var/lib/cloudera-scm-server


each host, create a parcels directory:
$ sudo mkdir -p /opt/cloudera/parcels
chown cloudera-scm:cloudera-scm /opt/cloudera/parcels

/opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-server start
cp /opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-server /etc/init.d/cloudera-scm-server
chkconfig cloudera-scm-server on
/opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-agent start
cp /opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-agent /etc/init.d/cloudera-scm-agent
chkconfig cloudera-scm-agent on

On the Cloudera Manager Server host, open the /etc/init.d/cloudera-scm-server file and change the value of CMF_DEFAULTS from ${CMF_DEFAULTS:-/etc/default} to  /opt/cloudera-manager/cm-5.6.0/etc/default
On each Agent, open the tarball_root/etc/init.d/cloudera-scm-agent file and change the value of CMF_DEFAULTS from ${CMF_DEFAULTS:-/etc/default} to /opt/cloudera-manager/cm-5.6.0/etc/default

所有节点安装依赖包 yum -y install wget bind-utils psmisc libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse portmap fuse-libs redhat-lsb

所有节点卸载mysql，避免过程中与需要安装的mariadb的lib包冲突

配置节点ssh用户免密码
all节点  ssh-keygen -t rsa
主结点  cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
scp文件到其他机器 scp ~/.ssh/authorized_keys root@centos2:~/.ssh/
