ansible deploy nfs

Preface

Use a virtual machine to create two cloud hosts with centos7.9 system. One of them serves as the mother machine of ansible and is named ansible. The other cloud host is named node1. Use this mother machine to write an ansible script.

Host	IP
ansible	192.168.200.50
node1	192.168.200.51

Configure basic environment

[root@localhost ~]# hostnamectl set-hostname ansible
[root@localhost ~]# bash
[root@ansible ~]# 

[root@localhost ~]# hostnamectl set-hostname node1
[root@localhost ~]# bash
[root@node1 ~]# 

[root@ansible ~]# systemctl stop firewalld
[root@ansible ~]# setenforce 0
[root@ansible ~]# 

[root@node1 ~]# systemctl stop firewalld
[root@node1 ~]# setenforce 0
[root@node1 ~]# 

[root@ansible ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.50 ansible
192.168.200.51 node1
[root@ansible ~]# 

[root@node1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.50 ansible
192.168.200.51 node1
[root@node1 ~]# 
[root@ansible ~]# ssh-keygen
[root@ansible ~]# ssh-copy-id root@node1

Configure ansible and centos warehouses

[root@ansible ~]# ls
anaconda-ks.cfg  ansible.tar.gz
[root@ansible ~]# tar -zxvf ansible.tar.gz -C /opt/
[root@ansible ~]# mkdir /opt/centos
[root@ansible ~]# mount /dev/sr0 /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@ansible ~]# cp -rfv /mnt/* /opt/centos/
[root@ansible ~]# umount /mnt/
[root@ansible ~]# mv /etc/yum.repos.d/* /mnt/
[root@ansible ~]# vi /etc/yum.repos.d/ftp.repo
[root@ansible ~]# cat /etc/yum.repos.d/ftp.repo 
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[ansible]
name=ansible
baseurl=file:///opt/ansible
gpgcheck=0
enabled=1
[root@ansible ~]# 

Configure ansible file

[root@ansible ~]# yum install -y vsftpd ansible
[root@ansible ~]# echo "anon_root=/opt" >> /etc/vsftpd/vsftpd.conf
[root@ansible ~]# systemctl restart vsftpd
[root@ansible ~]# cat >> /etc/ansible/hosts <<eof
[node1]
192.168.200.51
eof
[root@ansible ~]# mkdir ansible_nfs
[root@ansible ~]# cd ansible_nfs/
[root@ansible ansible_nfs]# cat local.repo 
[centos]
name=centos
baseurl=ftp://ansible/centos
gpgcheck=0
enabled=1
[ansible]
name=ansible
baseurl=ftp://ansible/ansible
gpgcheck=0
enabled=1
