ansible-playbook -i /etc/ansible/shell/iphost.py site.yml --extra-vars "myid=1 host=n16"
ansible-playbook -i /etc/ansible/shell/iphost.py site.yml --extra-vars "myid=2 host=d17"
ansible-playbook -i /etc/ansible/shell/iphost.py site.yml --extra-vars "myid=3 host=d18"

用ansible的shell sudo -i -u hadoop /home/hadoop/zookeeper/bin/zkServer.sh start
启动zkServer
