前言

使用虚拟机创建2台系统为centos7.9 的云主机，其中一台作为 ansible 的母机并命名为 ansible，另外一台云主机命名为 node1，用这台母机，编写 ansible 脚本

主机	IP
ansible	192.168.200.50
node1	192.168.200.51

配置基础环境

[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

配置ansible和centos的仓库

[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 ~]# 

配置ansible文件

[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
[root@ansible ansible_nfs]# 
[root@ansible ansible_nfs]# cat install_nfs.yaml

  hosts: node1
  become: true
  vars:
    nfs_export_dir: "data"
  tasks:
    - name: Copy local.repo file to node1
      copy:

      become: true
    - name: exportfs
      shell: exportfs -r
    - name: Start NFS service
      service:
        name: nfs
        state: started
        enabled: true
      become: true
[root@ansible ansible_nfs]# 
[root@ansible ansible_nfs]# cat exports.j2 
data 192.168.200.0/24(rw,all_squash)
[root@ansible ansible_nfs]# 

执行文件

[root@ansible ansible_nfs]# ansible-playbook install_nfs.yaml

验证

[root@node1 ~]# cat /etc/exports
data 192.168.200.0/24(rw,all_squash)
[root@node1 ~]# ls
anaconda-ks.cfg  data
[root@node1 ~]# showmount -e 192.168.200.51
Export list for 192.168.200.51:
