CentOS7离线安装Cloudera Manager 5.15.1

前言

本文主要记录Centos7.3 离线安装CDH和Cloudera Manager。安装的版本为Cloudera Manager 5.15.1,如遇不同版本,安装方式大致相同。

内容 版本
OS CentOS Linux release 7.3.1611
JDK 1.7
Cloudera Manager 5.15.1

本次安装使用了3台虚拟机服务器

主机名 配置 IP 用途
cdh01 4核8G内存 192.168.1.21 主,安装CM
cdh02 4核8G内存 192.168.1.22 从,slaver
cdh03 4核8G内存 192.168.1.23 从,slaver

1、准备工作

1.1 虚拟机环境准备

  1. 3台虚拟机分别安装操作系统,配置网络IP地址、主机名
  2. 修改SELINUX=disabled,重启主机
  3. 关闭防火墙
systemctl disable firewalld
systemctl stop firewalld

1.2 配置hosts

echo '192.168.1.21 cdh01
192.168.1.22 cdh02
192.168.1.23 cdh03' >> /etc/hosts

1.3 配置所有节点ssh无密码登录

先在cdh01上执行:

ssh-keygen -t rsa   #一路回车到完成

ssh-copy-id -i ~/.ssh/id_rsa.pub root@cdh01   #将公钥拷贝到本机的authorized_keys上

再在其他节点分别执行以下命令:

ssh-keygen -t rsa   #一路回车到完成

ssh-copy-id -i ~/.ssh/id_rsa.pub root@cdh01   #注意此处不变,将公钥拷贝到cdh01的authorized_keys上

在cdh01上,将authorized_keys分发到其他节点服务器:

scp ~/.ssh/authorized_keys root@cdh02:~/.ssh/

scp ~/.ssh/authorized_keys root@cdh03:~/.ssh/

1.4 安装配置NTP同步

1)所有节点执行yum install -y ntp安装ntp服务

2)在cdh02, cdh03上修改/etc/ntp.conf配置,修改成如下配置

server cdh01
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst

3)检查每个节点的ntp服务状态:ntpq -p

cdh01:

[root@cdh01 ~]# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*cn.ntp.faelix.n 185.134.196.169  2 u   21   64  377  286.756   14.200 184.209

CDH02/03:

 

[root@cdh02 ~]# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 cdh01           185.134.197.4    3 u   49   64    0    0.000    0.000   0.000
*biisoni.miuku.n 204.123.2.72     2 u   38   64    1  193.145   15.573   0.137

3)在每个节点上将cloudera-manager.repo拷贝到/etc/yum.repos.d/

cp /root/soft/cloudera-manager.repo /etc/yum.repos.d/

3 安装软件

3.1 软件包安装

在每个节点/root/soft目录下执行:1)安装命令

yum localinstall -y --nogpgcheck *.rpm

2)添加java环境变量

echo 'export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera
export CLASSPATH=.:$CLASSPTAH:$JAVA_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin ' >> /etc/profile
source /etc/profile

安装完后检查 

yum list | grep cloudera
yum list | grep oracle-j2sdk
service cloudera-scm-agent status  #检查agent状态

检查java命令是否正常 

java -version

每个节点配置sudoers,否则后面安装HDFS/Hive等服务时会报错误

echo 'cloudera-scm    ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers

由于上面的软件包是使用root用户安装的,而运行时用户为cloudera-scm,需要在每个节点上重设一下/var/log/cloudera-scm-agent下文件的权限

chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-agent/ -R
service cloudera-scm-agent restart

 3.2 安装cloduera manager二进制安装包

 进入cdh01的/root/soft所在目录 
设置安装权限并执行安装:

chmod u+x cloudera-manager-installer.bin

./cloudera-manager-installer.bin

如果提示需要删除配置文件,则删除该文件

rm -rf /etc/cloudera-scm-server/db.properties

重新执行安装命令,根据安装向导一路next。注意,如果之前master上没有手动安装rpm包此时就会联网下载,下载速度一般都较慢,太费时间。如果出现下面的错误,可以重新执行安装命令,直到提示安装成功。

相同配置下顺利安装时间在1分钟内即可完成。 
然后我们在web浏览器访问 http://192.168.1.21:7180/,看是否能打开页面即可,先不要进行登录操作。

注意:chd server服务器启动需要一些时间,等1分钟左右。

如果能访问,那证明 cloudera manager安装正常。
 

4 CDH服务安装

4.1 制作本地parcel

前面完成cloudera manager安装之后cdh01会在/opt目录下生成cloudera文件夹,将之前下载好的CDH-*文件移动到parcel-repo文件夹中,在cdh01中执行:

mv CDH-5.15.1-1.cdh5.15.1.p0.4-el7.parcel /opt/cloudera/parcel-repo
mv CDH-5.15.1-1.cdh5.15.1.p0.4-el7.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.15.1-1.cdh5.15.1.p0.4-el7.parcel.sha    #注意后缀名有重命名

将cloudera manager的用户授权给/opt和日志目录:

chown cloudera-scm:cloudera-scm /opt/cloudera/ -R
chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-agent/ -R

重启cloudera-scm-server(重要)

/etc/init.d/cloudera-scm-server restart #或者 systemctl restart cloudera-scm-server

重启速度较慢,约1-2分钟后访问 http://192.168.1.21:7180/ 登陆,账号密码 admin, 密码admin
选择免费版本,一路next开始安装。

完成安装后,进入系统 

è¿éåå¾çæè¿°

服务命令

systemctl status cloudera-scm-server      #主
systemctl status cloudera-scm-server-db   #主
systemctl status cloudera-scm-agent

错误排查

1. 添加节点时安装失败:

1) service cloudera-scm-agent status检查状态,如果状态异常且出现bash: /var/log/cloudera-scm-agent/cloudera-scm-agent.out: Permission denied,则需要给/var/log/cloudera-scm-agent/cloudera-scm-agent.out赋权限(参考4.1节)

2)安装失败

重启机器重试

2. 安装hadoop失败

Removing any leveldbjni library files left over from previous runs

此步安装过程中如果出现失败,则查看stderr的日志。

  • zookeeper安装失败

检查/var/lib/zookeeper和/var/log/zookeeper、/var/lib/zookeeper/version-2目录是否存在且属主为cloudera-scm

  • 执行服务 Hive 上的命令 部署客户端配置

stderr日志错误最后打印为sudo /usr/sbin/update-alternatives --auto hive-conf。重新执行即成功

  • 启动oozie失败

stderr日志:1)/var/lib/oozie/tomcat-deployment目录不存在时创建目录并修改属主
2)Can't load server.xml from /var/lib/oozie/tomcat-deployment/conf/server.xml,在/usr/lib64/cmf/service/oozie/oozie.sh中加sleep,原因未知

  • yarn启动失败

mkdir /var/log/hadoop-yarn && chown cloudera-scm:cloudera-scm /var/log/hadoop-yarn

查看stderr中的日志,发现在/var/log下还需要zookeeper、cloudera-scm-eventserver、cloudera-scm-firehose目录

mkdir /var/log/zookeeper && chown cloudera-scm:cloudera-scm /var/log/zookeeper
mkdir /var/log/cloudera-scm-eventserver && chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-eventserver
mkdir /var/log/cloudera-scm-firehose && chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-firehose

mkdir /var/lib/zookeeper && chown cloudera-scm:cloudera-scm /var/lib/zookeeper
