Redis 主从备份，哨兵设置

环境 Centos 7，redis 4.0.6

三个centos 7实例

1.将redis解压到目录（/bak/soft/）

tar -zxvf 压缩包名 解压目录

2.创建日志和数据恢复目录

mkdir -p /bak/soft/logs/redis
mkdir -p /bak/soft/cdata/redis
mkdir -p /bak/soft/logs/redis-sentinel
mkdir -p /bak/soft/cdata/redis-sentinel

3.配置redis-master.conf

daemonize yes
masterauth "ADMINadmin123"
requirepass "ADMINadmin123"
pidfile "/var/run/redis_6379.pid"

# Generated by CONFIG REWRITE

slaveof 172.31.193.221 6379

6.配置sentinel.conf文件master&slave&LBS配置可以一样

protected-mode no
port 26379
daemonize yes
sentinel monitor mymaster 172.31.193.221 6379 2
logfile "/bak/soft/logs/redis/sentinel.log"
dir "/bak/soft/cdata/redis-sentinel"
sentinel auth-pass mymaster ADMINadmin123


#下面不用复制，myid为自动生成，slave节点也是自动添加
protected-mode no
port 26379
daemonize yes
sentinel myid f7564fc40667bb5e336c6566acc28654d0c40d39
sentinel monitor mymaster 172.31.193.221 6379 2
logfile "/bak/soft/logs/redis/sentinel.log"
dir "/bak/soft/cdata/redis-sentinel"
sentinel auth-pass mymaster ADMINadmin123
sentinel config-epoch mymaster 4
sentinel leader-epoch mymaster 4
sentinel known-slave mymaster 172.31.193.222 6379
sentinel known-slave mymaster 172.31.193.224 6379
sentinel known-sentinel mymaster 172.31.193.222 26379 96d7940391c5f9f386dedc1eb7a5b221e458428a
sentinel known-sentinel mymaster 172.31.193.224 26379 d5202361f59b4695ebe8a7cefd26c61466637554
sentinel current-epoch 4

7.配置redis.properties连接信息master&slave&LBS可以一样

redis.address=172.31.193.221:26379;172.31.193.222:26379;172.31.193.224:26379
redis.pool.testOnBorrow=true
redis.pool.testOnReturn=false
redis.pool.testWhileIdle=false
redis.pool.maxIdle=300
redis.pool.minIdle=15
redis.pool.maxActive=1000
redis.pool.maxWait=10000
redis.pool.timeout=10000
redis.pool.numTestsPerEvictionRun=0
redis.pool.timeBetweenEvictionRunsMillis=0
redis.pool.minEvictableIdleTimeMillis=0
redis.password=ADMINadmin123
redis.type=sentinel
redis.master.name=mymaster

8.修改防火墙规则，开放端口

#查看防火墙状态
service iptables status

#测试端口是否开放
telnet ip 端口

#修改防火墙规则
vim /etc/sysconfig/iptables
-A INPUT -p tcp -m tcp --dport 6379 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 26379 -j ACCEPT

service iptables restart

#若已经启动redis，kill进程重启服务
ps aux |grep redis
kill -9 进程号

9.启动redis顺序，master—>slave&LBS—>三个哨兵

/bak/soft/redis-4.0.6/redis-server /etc/redis.conf
/bak/soft/redis-4.0.6/redis-sentinel /etc/sentinel.conf

#查看日志
tail 100 /bak/soft/logs/redis/redis.log

#查看日志
tail 100 /bak/soft/logs/redis/redis.log

10.测试停止master节点，slave或LBS节点将被选举为master节点

再重启master自动变成slave
