redis哨兵常用命令和監控示例詳解
sentinel monitor advertise 192.168.0.5 28001 2
sentinel set advertise client-reconfig-script /etc/redis/reconfig.sh
sentinel flushconfig
sentinel啟動後需要手動將配置文件對應的調整為sentinel deny-scripts-reconfig no,否則不支持命令行runtime修改client-reconfig-script
# SECURITY
#
# By default SENTINEL SET will not be able to change the notification-script
# and client-reconfig-script at runtime. This avoids a trivial security issue
# where clients can set the script to anything and trigger a failover in order
# to get the program executed.
#sentinel deny-scripts-reconfig yes
role命令
查看sentinel monitor的master names名字
sentinel masters
查看所有監控master及其配置信息
sentinel master monitor_name
查看指定監控master及其配置信息
sentinel failover monitor_name
手動進行swithover切換主從,如果有多個slave會選擇哪個slave做為新的master,待測試?
sentinel moniotr <name> <ip> <port> <quorum>
添加監視的master
sentinel remove monitor_name
將監視的為name的master移除監視
sentinel set <mastername> [<option> <value>]
修改監視的master的一些屬性
down-after-milliseconds 過瞭這個時間考慮master go down
failover-timeout 刷新故障轉移狀態的最大時間
parallel-syncs slave同時reconfigure的個數
notification-script 設置通知腳本
client-reconfig-script 設置通知腳本
auth-pass 執行auth的密碼
quorum 修改master的quorum
sentinel flushconfig
將sentinel信息寫入到配置文件中
sentinel配置文件示例:
daemonize yes pidfile "/home/redis/sentinel/25000/redis.pid" loglevel notice protected-mode yes bind 192.168.100.5 logfile "/home/redis/sentinel/25000/redis.log" port 25000 dir "/home/redis/sentinel/25000" # Generated by CONFIG REWRITE sentinel myid 0338c4ceb7cf39a8037a22fa17d0f7a76923b5a0 sentinel deny-scripts-reconfig no sentinel monitor advertise 192.168.100.5 28001 2 sentinel client-reconfig-script advertise /etc/redis/reconfig.sh sentinel config-epoch advertise 4 sentinel leader-epoch advertise 4 sentinel known-replica advertise 192.168.100.6 28001 sentinel known-sentinel advertise 192.168.100.7 25000 06f937e1d35496dc66d2899e3b25e286ff91d658 sentinel known-sentinel advertise 192.168.100.6 25000 ede86ac0b7d2ff7b532d0e5352ba6e33dd36670e sentinel monitor mymaster1 192.168.100.6 28002 2 sentinel client-reconfig-script mymaster1 /etc/redis/reconfig.sh sentinel config-epoch mymaster1 5 sentinel leader-epoch mymaster1 1 sentinel known-replica mymaster1 192.168.100.5 28002 sentinel known-sentinel mymaster1 192.168.100.7 25000 06f937e1d35496dc66d2899e3b25e286ff91d658 sentinel known-sentinel mymaster1 192.168.100.6 25000 ede86ac0b7d2ff7b532d0e5352ba6e33dd36670e sentinel current-epoch 5
