安装Zabbix5.0
目录
概述
Zabbix 5.0已经正式发布，相比4.0，它在可用性，安全性和完整性方面都有一系列重要改进。
支持的平台
除了现有的官方软件包和appliances外，Zabbix 5.0现在还支持以下平台：
- SUSE Linux Enterprise Server 15
- Debian 10
- Ubuntu 20.04
- Raspbian 10
- Mac OS/X
- RHEL 8
- CentOS 8
- MSI for Windows Agent
安全相关
SAML用于在安全身份提供者处提供单点身份验证，这意味着用户登录认证需要满足防火墙的安全策略，然后SAML用于向Zabbix和其他应用程序声明身份。SAML方式的支持使Zabbix具备开箱即用的与各种本地和云身份提供商（如Microsoft ADFS、OpenAM、Secureath、Okta、Auth0等）集成的功能。
Zabbix 5.0为更安全的监控进行了重大改进：
- 支持Webhook的HTTP代理，使从Zabbix server到外部告警和ITSM系统的连接更加安全和可控
- agent端的监控指标支持黑名单和白名单
- 所有Zabbix组件都可配置密码，以避免在TLS连接中使用非安全密码
- 支持到MySQL和PostgreSQL后端的加密连接
- 更强大的SHA256用于保存用户密码的Hash值
Zabbix 5.0支持更隐秘的用户宏，用于保存任何敏感信息，如不希望向最终用户公开的密码和API令牌。
支持TimescaleDB
Zabbix 5.0支持对TimescaleDB收集的数据进行可选压缩。除了TimescaleDB的通用优势（自动表分区、高性能和可扩展性）之外，它还有助于进一步提高性能和降低存储成本。
Zabbix用户界面也得到了改进，以支持监控和管理数百万受监控设备。
agent升级
新一代agent为Linux和Windows提供了一系列新功能和高级监控功能：
- 用Golang编写
- 用于监控各种服务和应用程序的插件框架
- 在执行监控检查时能保持现有状态（例如，保持持久的数据库连接）
- 支持trapping
- 内置调度器，支持灵活的时间间隔
- 使用批量数据传输实现高效的网络使用
- 支持持续存储收集的数据
- 直接替换Linux和Windows上的现有agent
