HA 集群状态active 正常standby 待机unavailable 不可用stopped 停用# 查看HA状态
zabbix_server -R ha_status # 切换细节
主节点和备节点每5秒更新一次上次访问时间。每个备节点监控主节点的最后一次访问时间。
如果主节点的最后一次访问时间超过了“故障转移延迟”秒备用节点将自己切换为主节点
并将“unavailable”状态分配给先前的主节点。# 修改切换时间10s-15min
zabbix_server -R ha_set_failover_delay5m命令查看HA状态 单节点配置HA 两节点完成HA配置 切换手动停1节点 切换手动停1节点2节点日志显示standby切换为active 2. 访问高可用 php
