本次要求是哨兵叢集版本
1.下載所需要版本包
[root@app-bj-ali-ecs1 ~]# wget http://download.redis.io/releases/redis-6.0.6.tar.gz [root@app-bj-ali-ecs1 ~]# tar xzf redis-6.0.6.tar.gz [root@app-bj-ali-ecs1 ~]# cd redis-6.0.6 [root@app-bj-ali-ecs1 ~]# make [root@app-bj-ali-ecs1 ~]# make install [root@app-bj-ali-ecs1 ~]# cd [root@app-bj-ali-ecs1 ~]# mv redis-6.0.6 /usr/local/redis [root@app-bj-ali-ecs1 ~]# cd /usr/local/redis/ [root@app-bj-ali-ecs1 redis]# src/redis-server # 可以正常啟動，安裝成功 58034:C 06 Dec 2024 18:18:34.236 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 58034:C 06 Dec 2024 18:18:34.236 # Redis version=6.0.6, bits=64, commit=00000000, modified=0, pid=58034, just started 58034:C 06 Dec 2024 18:18:34.236 # Warning: no config file specified, using the default config.

2.實現主從叢集
由於測試環境僅有一臺機器，因此設定6379為主，6380、6381為從，即一主雙從
[root@app-bj-ali-ecs1 redis]# vim conf/6379.conf daemonize yes masterauth 123456 min-replicas-to-write 1 min-replicas-max-lag 10 requirepass 123456 appendonly yes [root@app-bj-ali-ecs1 redis]# vim conf/6380.conf daemonize yes port 6380 # 修改埠 replicaof 172.18.169.29 6379 # 設定主資訊 masterauth 123456 min-replicas-to-write 1 min-replicas-max-lag 10 requirepass 123456 appendonly yes [root@app-bj-ali-ecs1 redis]# vim conf/6381.conf daemonize yes port 6381 # 修改埠 replicaof 172.18.169.29 6379 # 設定主資訊 masterauth 123456 min-replicas-to-write 1 min-replicas-max-lag 10 requirepass 123456 appendonly yes [root@app-bj-ali-ecs1 redis]# src/redis-server conf/6379.conf >> logs/6379.log & [root@app-bj-ali-ecs1 redis]# src/redis-server conf/6380.conf >> logs/6380.log & [root@app-bj-ali-ecs1 redis]# src/redis-server conf/6381.conf >> logs/6381.log & [root@app-bj-ali-ecs1 redis]# src/redis-cli -p 6379 -a 123456 Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 127.0.0.1:6379> INFO replication # Replication role:master # 身份正常 connected_slaves:2 # 狀態正常 min_slaves_good_slaves:2 slave0:ip=172.18.169.29,port=6380,state=online,offset=434,lag=0 # 從6380正常 slave1:ip=172.18.169.29,port=6381,state=online,offset=434,lag=1 # 從6381正常 master_replid:961eaeac79b010b491ea4f2ce75c123c91d1e5ff master_replid2:0000000000000000000000000000000000000000 master_repl_offset:448 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:1 repl_backlog_histlen:448
2.實現哨兵
哨兵至少需要三臺，由於測試環境僅有一臺機器，因此設定26379，26380、26381為不同例項進行實現
[root@app-bj-ali-ecs1 redis]# vim conf/26379.conf daemonize yes sentinel monitor mymaster 172.18.169.29 6379 2 # 改成自己的ip sentinel auth-pass mymaster 123456 [root@app-bj-ali-ecs1 redis]# vim conf/26380.conf daemonize yes port 26380 sentinel monitor mymaster 172.18.169.29 6379 2 sentinel auth-pass mymaster 123456 [root@app-bj-ali-ecs1 redis]# vim conf/26381.conf daemonize yes port 26381 sentinel monitor mymaster 172.18.169.29 6379 2 sentinel auth-pass mymaster 123456 [root@app-bj-ali-ecs1 redis]# src/redis-sentinel conf/26379.conf >> logs/26379.log & [root@app-bj-ali-ecs1 redis]# src/redis-sentinel conf/26380.conf >> logs/26380.log & [root@app-bj-ali-ecs1 redis]# src/redis-sentinel conf/26381.conf >> logs/26381.log & [root@app-bj-ali-ecs1 redis]# src/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=mymaster,status=ok,address=172.18.169.29:6379,slaves=2,sentinels=3 # 6379為主，兩從，三個哨兵，狀態正常
