redis创建sentinel参考

在从节点上执行：slaveof 192.168.56.201 6379 #master的ip地址和端口

也可以在配置文件中配置：

slaveof 192.168.56.201 6379

确认：

[root@db1 ~]# redis-cli

127.0.0.1:6379> info replication

# Replication

role:master

connected_slaves:2

slave0:ip=192.168.56.202,port=6379,state=online,offset=1344537,lag=0

slave1:ip=192.168.56.203,port=6379,state=online,offset=1344537,lag=0

master_replid:78461067504e80e7adf61bd14ea1a385c38ca20c

master_replid2:0000000000000000000000000000000000000000

master_repl_offset:1344688

second_repl_offset:-1

repl_backlog_active:1

repl_backlog_size:10485760

repl_backlog_first_byte_offset:1

repl_backlog_histlen:1344688

2.创建目录：

mkdir -p /data/redis-26379/logs/

mkdir -p /data/redis-26379/run

3.编辑哨兵参数(scp都其它两个机器)：

vim /data/redis-26379/26379.conf

port 26379

daemonize yes

dir /data/redis-26379/

pidfile /data/redis-26379/redis_26379.pid

logfile /data/redis-26379/logs/26379.log

#bind填写本机ip地址和127.0.0.1

bind 192.168.56.201 127.0.0.1

sentinel monitor master-monitor1 192.168.56.201 6379 2

sentinel down-after-milliseconds master-monitor1 10000

sentinel parallel-syncs master-monitor1 1

sentinel failover-timeout master-monitor1 180000

4.启动哨兵节点：

redis-sentinel /data/redis-26379/26379.conf

登录查看信息：

redis-cli -p 26379

127.0.0.1:26379> info sentinel

# Sentinel

sentinel_masters:1

sentinel_tilt:0

sentinel_running_scripts:0

sentinel_scripts_queue_length:0

sentinel_simulate_failure_flags:0

master0:name=master-monitor1,status=ok,address=192.168.56.201:6379,slaves=2,sentinels=3

此时看到哨兵配置文件已经改变,自动发现slave：

[root@db1 redis-26379]# cat 26379.conf

port 26379

daemonize yes

dir "/data/redis-26379"

pidfile "/data/redis-26379/redis_26379.pid"

logfile "/data/redis-26379/logs/26379.log"

#bind 信息填写本机ip地址 和127.0.0.1

bind 192.168.56.201 127.0.0.1

sentinel myid 6ba1b2245916983baabaacf1be1eb0303a2a1b8b

sentinel deny-scripts-reconfig yes

sentinel monitor master-monitor1 192.168.56.202 6379 2
