四、基础环境配置
1.SSH免密登录
在hdp01、hdp02上生成公钥，配置免密登录到其他节点
ssh-keygen -t rsa -f ~/.ssh/id_rsa -C username_root
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@192.168.111.201
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@192.168.111.202
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@192.168.111.203
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@192.168.111.204
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@192.168.111.205
2.ansible安装
配置ansible和rhel-system-roles，创建配置文件
mkdir /root/ansible
cd /root/ansible
cp /etc/ansible/ansible.cfg /root/ansible/
修改配置文件，/root/ansible/ansible.cfg
[defaults]
inventory = /root/ansible/inventory
ask_pass = false
remote_user = root
配置inventory文件，/root/ansible/inventory
[hdp:children]
nn
dn
[nn]
192.168.111.201 hostname=hdp01
192.168.111.202 hostname=hdp02
[dn]
192.168.111.203 hostname=hdp03
192.168.111.204 hostname=hdp04
192.168.111.205 hostname=hdp05
3.修改hostname
创建playbook，/root/ansible/hostname.yml
---
- name: modify hostnamehosts: alltasks:- name: modify hostname permanentlyraw: "echo {{ hostname | quote }} > /etc/hostname"- name: modify hostname temporarilyshell: hostname {{ hostname | quote }}
执行并确认
ansible-playbook /root/ansible/hostname.yml
ansible all -m shell -a 'hostname'
4.修改hosts列表
在nn01上修改主机列表，/etc/hosts
192.168.111.201 hdp01.hdp.com hdp01
192.168.111.202 hdp02.hdp.com hdp02
192.168.111.203 hdp03.hdp.com hdp03
192.168.111.204 hdp04.hdp.com hdp04
192.168.111.205 hdp05.hdp.com hdp05
分发至其他节点
ansible all -m template -a 'src=/etc/hosts dest=/etc/hosts'
5.安装基础软件
安装vim等基础软件，/root/ansible/packages.yml
---
- hosts: alltasks:- name: install packagesyum:name:- pciutils- bash-completion- vim- chronystate: present
6.关闭firewall和SELinux
关闭firewall
ansible all -m service -a 'name=firewalld state=stopped enabled=no'
ansible all -m shell -a 'systemctl status firewalld | grep Active'
关闭SELinux
ansible all -m selinux -a 'policy=targeted state=disabled'
ansible all -m shell -a 'getenforce'
7.NTP时钟
以hdp01为时钟源，其余节点从nn01进行时钟同步
服务端（hdp01）
修改配置文件/etc/chrony.conf
# 不指定外部NTP源
# 允许本网段其节点作为客户端访问
allow 192.168.111.0/24
# 如果时间服务可不用，则使用本地时间作为标准时间授权，层数为10
local stratum 10
重启服务
systemctl restart chronyd
客户端（hdp02-hdp05）
安装ntp时钟，/root/ansible/timesync.yml
---
- hosts: 192.168.111.202,dnvars:timesync_ntp_servers:- hostname: 192.168.111.201iburst: yesroles:- rhel-system-roles.timesync
执行
ansible-playbook /root/ansible/timesync.yml
确认时钟同步情况
ansible 192.168.111.202,dn -m shell -a 'chronyc sources -v'
8.磁盘分区、文件系统及挂载目录
创建分区parted.yml文件
---
- hosts: alltasks:- name: parted devicesparted:device: "{{ item }}"number: 1label: gptstate: presentloop:- /dev/sdb- /dev/sdc- /dev/sddignore_errors: yes
确认结果
ansible all -m shell -a 'lsblk -f'
创建文件系统mkfs.yml文件
---
- hosts: alltasks:- name: mkdir of nnfile:path: /data01state: directorywhen: inventory_hostname in groups['nn']- name: mkdir of dnfile:path: "{{ item }}"state: directoryloop:- /data01- /data02- /data03when: inventory_hostname in groups['dn']- name: mkfsfilesystem:fstype: xfsdev: "{{ item }}"loop:- /dev/sdb1- /dev/sdc1- /dev/sdd1ignore_errors: yes- name: mount of nnmount:path: /data01src: /dev/sdb1fstype: xfsstate: mountedwhen: inventory_hostname in groups['nn']- name: mount of dnmount:path: "{{ item.p_dir }}"src: "{{ item.s_dir }}"fstype: xfsstate: mountedloop:- { p_dir: /data01, s_dir: /dev/sdb1 }- { p_dir: /data02, s_dir: /dev/sdc1 }- { p_dir: /data03, s_dir: /dev/sdd1 }when: inventory_hostname in groups['dn']
