##二：系统环境初始化
2.1: 系统环境介绍
系统：CentOS7.5X64
cat /etc/hosts
192.168.20.111 NN01.yl.com NN01
192.168.20.112 SN01.yl.com SN01
192.168.20.113 DN01.yl.com DN01
192.168.20.114 DN02.yl.com DN02
2.2：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
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
2.3: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 [email protected]:/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. NN01.yl.com:
vim /etc/chrony.conf 增加
----
注释掉相关默认的server
server ntp1.aliyun.com iburst
allow 192.168.20.111/16

chkconfig chronyd on
2. SN01.yl.com---DN01.yl.com 同步NN01.yl.com
vim /etc/chrony.conf
----
注释掉默认的server
server 192.168.20.111 iburst
----
service chronyd stop
service chronyd start
chkconfig chronyd on

cd /var/log/cloudera-scm-server/
tail -f cloudera-scm-server.log
选择更多parcel
所有节点执行：
echo vm.swappiness = 10 >> /etc/sysctl.conf
echo 10 > /proc/sys/vm/swappiness
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
将下面 两条命令

数据库授权：
mysql -uroot -pQingchun123.com
---
创建hive 所需要的库并授权：
mysql >create database cdh_hive default character set latin1;
字符必须为拉丁(latin1),如果uft8可能会报错Specified key was too long; max key length is 767 bytes
mysql >grant all privileges on cdh_hive.* to 'hive'@'%' identified by 'Hive_123' with grant option;
mysql >grant all privileges on cdh_hive.* to 'hive'@'NN01.yl.com' identified by 'Hive_123' with grant option;
mysql >flush privileges;
创建oozie 所需要的库
mysql >create database cdh_oozie default character set utf8;
mysql >grant all privileges on cdh_oozie.* to 'oozie'@'%' identified by 'Oozie_123' with grant option;
mysql >grant all privileges on cdh_oozie.* to 'oozie'@'NN01.yl.com' identified by 'Oozie_123' with grant option;
mysql >flush privileges;
创建hue所需要的库：
mysql >create database cdh_hue default character set utf8;
mysql >grant all privileges on cdh_hue.* to 'hue'@'%' identified by 'Hue_123' with grant option;
mysql >grant all privileges on cdh_hue.* to 'hue'@'NN01.yl.com' identified by 'Hue_123' with grant option;
mysql >flush privileges;
创建CM 的 监控端Activity Monitor 的库

mysql >grant all privileges on cdh_am.* to 'am'@'%' identified by 'Am_123' with grant option;
mysql >grant all privileges on cdh_am.* to 'am'@'NN01.yl.com' identified by 'Am_123' with grant option;
mysql >flush privileges;
创建RM 的 监控端 Reports Manager 的库
