一、zabbix6.0服务端部署脚本

  • 该脚本是幂等性的 可以重复执行 但需要注意 已经存在服务端的机器不可执行 否则会导致原有监控数据丢失💣

二、zabbix-agent二进制部署脚本

  • 该脚本是幂等性的 可以重复执行 但需要注意 已经存在客户端的机器不可执行 否则会导致原有监控数据丢失💣

  • zabbix-agent端配置注意事项 主要三项

    Server=10.0.0.10  # 服务端IP
    ### Option: ServerActive
    #               ServerActive=127.0.0.1:10051
    #               ServerActive=127.0.0.1:20051,zabbix.domain,[::1]:30051,::1,[12fc::1]
    #               ServerActive=zabbix.cluster.node1;zabbix.cluster.node2:20051;zabbix.cluster.node3
    #               ServerActive=zabbix.cluster.node1;zabbix.cluster.node2:20051,zabbix.cluster2.node1;zabbix.cluster2.node2,zabbix.domain
    # ServerActive=
    ServerActive=10.0.0.10  # 服务端IP
    ### Option: Hostname
    #       Value is acquired from HostnameItem if undefined.
    # Hostname=
    Hostname=10.0.0.11 # 客户端IP
    ### Option: HostnameItem
    #       Item used for generating Hostname if it is undefined. Ignored if Hostname is defined.
    # HostnameItem=system.hostname
    #       Aliases can be used in HostMetadataItem but not in HostnameItem parameters.

部署脚本如下：zabbix-agent.sh
