3、playbook 执行方法

# ansible-playbook playbooks/zabbix/zabbix_agent_install.yml

PLAY [lvs:nginx] ************************************************************************************************************************************************************************************************

192.168.1.126              : ok=6    changed=5    unreachable=0    failed=0   

4、再次确认 zabbix-agent 服务是否正常运行

# ansible -i /etc/ansible/environments/dev/hosts all -m shell -a "/etc/init.d/zabbix-agent status"
192.168.1.125 | SUCCESS | rc=0 >>
zabbix_agentd (pid  1283) is running...

192.168.1.126 | SUCCESS | rc=0 >>
zabbix_agentd (pid  1793) is running...
