Zabbix 3.x 升级到 Zabbix 4.x
## 前言
Zabbix目前已经发布4.0 LTS长期支持版，虽然很多插件还停留在3.4版本比如Grafana，但是还是要提前做好准备。生产环境建议暂时保持在3.4版本，因为在4.0版本中很多语法发生改变，建议仔细评估。最重要的事情提醒三遍，不要忘记备份，不要忘记备份，不要忘记备份。

mysqldump -uzabbix -pzabbix --opt --skip-lock-tables --database zabbix > zabbix.sql
mysqldump -uzabbix -pzabbix --opt --skip-lock-tables --database zabbix | gzip > zabbix_`date +%Y%m%d%H%M%S`.sql.gz
```
### CentOS
