主机清单

[ ~]# vim /etc/ansible/hosts
[db_group]
db01 ansible_ssh_host=172.16.1.51 asible_ssh_user=root ansible_ssh_port=22

导出数据库数据

1.备份db01上的数据库
mysqldump -uroot -p‘1‘ -A wp > /root/wp.sql

2.将web01上备份的数据库拷贝至m01服务器上
scp wp.sql  :/root/ansible/lb/

执行

1.执行base.yml
[ ~]# ansible-playbook ansible/base.yml 

2.执行rsync.yml
[ ~]# ansible-playbook ansible/nfs/nfs.yml -i /root/ansible/lb/hosts
