大数据运维专栏

• 一： 环境初始化
• 二： 安装CDH6.3.2

一：环境初始化

1.1 环境介绍

系统：CentOS7.5X64
cat /etc/hosts 
----
192.168.11.160  dev01.lanxintec.cn
192.168.11.161  dev02.lanxintec.cn
192.168.11.162  dev03.lanxintec.cn
----

1.2：无密钥登录配置

做root用户无密钥认证
 ssh-keygen ---一直敲回车到最后
 cat id_rsa.pub >> authorized_keys 
chmod 600 authorized_keys
 将所有的公钥导入authorized_keys  分发到 所有的 机器的.ssh/ 下面
 然后测试

1.3:关闭 firewalld，iptables 与 selinux

所有节点都要配置：
yum install -y firewall* iptable* 
  (1) 关闭firewalld
 systemctl stop firewalld.service
 systemctl disable firewalld.service
 firewall-cmd --state
 (2) 关闭iptables 
 iptables -F
 systemctl stop iptables.service 
 service iptables save
 systemctl disable iptables.service 
 (3) 禁用 selinux 
  sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config  
  setenforce 0
  getenforce 0
  sestatus
  重启机器
  reboot

2.4：所有机器更改CentOS7.5x64的文件句柄数

vim /etc/security/limits.conf
---
*               soft    nofile          65535
*               hard    nofile          1029345
*               soft    nproc           unlimited
*               hard    nproc           unlimited
*               soft    memlock         unlimited
*               hard    memlock         unlimited

在其它 节点上面执行命令：
rsync -arvzP root@192.168.100.11:/etc/security/limits.conf /etc/security/
同步limits.conf  文件

2.5 时间同步：

所有机器 yum install chrony*
1. dev01.lanxintec.cn---dev03.lanxintec.cn 同步阿里云的时间服务器:
vim /etc/chrony.conf 增加
----
注释掉相关默认的server
server ntp1.aliyun.com iburst
service chronyd start
chkconfig chronyd on 
service chronyd stop 
service chronyd start 
chkconfig chronyd on

#Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your
#system and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/mysql_binary_log
#In later versions of MariaDB, if you enable the binary log and do not set
#a server_id, MariaDB will not start. The server_id must be unique within
#the replicating group.

2.9配置 httpd 分发服务器

pre01.lanxintec.cn:
yum install -y httpd 

vim /etc/httpd/conf/httpd.conf
----
修改/etc/httpd/conf/httpd.conf配置文件，在<IfModule mime_module>中修改以下内容
AddType application/x-gzip .gz .tgz .parcel
----
service httpd start 
chkconfig httpd on 

做CM6.3.1 的 分发源
cd /var/www/html/cdh6.3.2
createrepo.

vim /etc/yum.repos.d/cloduera-manger.repo
------
[cmrepo]
name = cm_repo
baseurl =http://192.168.100.11/cdh6
enable = 1
gpgcheck = 0
-----
yum makecache fast

所有主机执行命令同步：
rsync -avrzP root@192.168.11.160:/etc/yum.repos.d/cloudera-manager.repo /etc/yum.repos.d/
yum makecache fast

2.10 配置mysql-jdbc

cd /usr/share/java/
cp -p mysql-connector-java-8.0.15.jar  mysql-connector-java.jar

三： 安装CDH6.3.2所需环境

3.1:安装所需依赖包

所有大数据节点都要安装：
yum -y install chkconfig python bind-utils psmisc libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse fuse-libs redhat-lsb postgresql* portmap mod_ssl openssl-devel python-psycopg2 MySQL-python

3.2 安装cloudera-server

yum install -y cloudera-manager-server 

3.3 在 mysql 当中创建 CM 需要的注册库

# mysql -uroot -pflyfish225
mysql> create database cmf character set utf8;
mysql> grant all privileges on cmf.* to 'cmf'@'%' identified by 'cmf_1234' with grant option;
mysql> grant all privileges on cmf.* to 'cmf'@'dev01.lanxintec.cn' identified by 'cmf_1234' with grant option;
mysql> flush privileges;

3.4 注入CM-server库 与 CM-agent端的server

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql cmf cmf cmf_1234

四： 配置CDH6.3.2的cloudera-manager安装

4.1 安装启动CM

service cloudera-scm-server start 
cd /var/log/cloudera-scm-server/
tail -f cloudera-scm-server.log

五： 打开web 安装：

echo 10 > /proc/sys/vm/swappiness
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo "vm.swappiness = 10" >> /etc/sysctl.conf 
sysctl -p 

vim /etc/rc.local
----
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
---

create database cdh_hive default character set latin1;
grant all privileges on cdh_hive.* to 'hive'@'%' identified by 'Hive_123' with grant option;
create database cdh_oozie default character set utf8;
grant all privileges on cdh_oozie.* to 'oozie'@'%' identified by 'Oozie_123' with grant option;
