服务启停：
systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd
浏览器安装：
默认用户名：Admin,密码：zabbix
设置启动和开机项：
ansible all -m shell -a 'systemctl stop zabbix-agent.service'
ansible all -m shell -a 'systemctl start zabbix-agent.service'
ansible all -m shell -a 'systemctl enable zabbix-agent.service'
ansible all -m shell -a 'systemctl status zabbix-agent.service'
客户端agent统一升级：
ansible all -m shell -a 'rpm -Uvh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm'
ansible all -m shell -a 'yum -y install zabbix-sender zabbix-agent zabbix-get'
