1.使用ansible 的 ad-hoc 搭建 NFS 服务? 31
1.安装nfs
# ansible nfs -m yum -a "name=nfs-utils state=present"
2.配置nfs
[root@manager ~/ansible-project1]# cat exports.j2

/data/zh 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)
/data/ansible 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)
[root@manager ~/ansible-project1]# ansible nfs -m copy -a "src=./exports.j2 dest=/etc/exports owner=root group=root mode=0644 backup=yes"
3.根据配置文件进行初始化操作 创建用户 创建目录 授权
[root@manager ~/ansible-project1]# ansible nfs -m group -a "name=www gid=666 state=present"
[root@manager ~/ansible-project1]# ansible nfs -m user -a "name=www uid=666 group=www state=present"

3.启动nfs
[root@manager ~/ansible-project1]# ansible nfs -m systemd -a "name=nfs state=restarted enabled=yes"
2.使用ansible 的 ad-hoc 实现 NFS 挂载? 7
1.安装nfs-utils工具

2.使用mount挂载即可
[root@manager ~/ansible-project1]# ansible web -m mount -a "src=172.16.1.31:/data/ansible path=/mnt fstype=nfs opts=defaults state=mounted"
[root@manager ~/ansible-project1]# cat nfs-server.yml
