redis常用命令及使用方法

1、redis-benchmark

redis基准信息，redis服务器性能检测

redis-benchmark -h localhost -p 6379 -c 100 -n 100000

100个并发连接，100000个请求，检测host为localhost 端口为6379的redis服务器性能

[root@Architect redis-1.2.6]# redis-benchmark -h localhost -p 6379 -c 100 -n 100000 ====== PING ====== 10001 requests completed in 0.41 seconds   50 parallel clients   3 bytes payload   keep alive: 1    0.01% <= 0 milliseconds  23.09% <= 1 milliseconds  85.82% <= 2 milliseconds  95.60% <= 3 milliseconds  97.20% <= 4 milliseconds  97.96% <= 5 milliseconds  98.83% <= 6 milliseconds  99.41% <= 7 milliseconds  99.70% <= 8 milliseconds  99.99% <= 9 milliseconds  100.00% <= 12 milliseconds  24274.27 requests per second

2、redis-cli

redis-cli -h localhost -p 6380 monitor

Dump all the received requests in real time;

监控host为localhost，端口为6380，redis的连接及读写操作

[root@Architect redis-1.2.6]# redis-cli -h localhost -p 6380 monitor  +OK  +1289800615.808225 "monitor"  +1289800615.839079 "GET" "name"  +1289800615.853694 "PING"  +1289800615.853783 "PING"  +1289800615.854646 "PING"  +1289800615.854974 "PING"  +1289800615.857693 "PING"  +1289800615.866862 "PING"  +1289800615.871944 "PING"

redis-cli -h localhost -p 6380 info

Provide information and statistics about the server ;

提供host为localhost，端口为6380，redis服务的统计信息

[root@Architect redis-1.2.6]# redis-cli -h localhost -p 6380 info  redis_version:2.0.4  redis_git_sha1:00000000  redis_git_dirty:0  arch_bits:32  multiplexing_api:epoll  process_id:21990  uptime_in_seconds:490580  uptime_in_days:5  connected_clients:103  connected_slaves:0  blocked_clients:0  used_memory:4453240  used_memory_human:4.25M  changes_since_last_save:200  bgsave_in_progress:0  last_save_time:1290394640  bgrewriteaof_in_progress:0  total_connections_received:809  total_commands_processed:44094018  expired_keys:0  hash_max_zipmap_entries:64  hash_max_zipmap_value:512  pubsub_channels:0  pubsub_patterns:0  vm_enabled:0  role:slave  master_host:localhost  master_port:6379  master_link_status:up  master_last_io_seconds_ago:18  db0:keys=1319,expires=0

3、redis-stat

redis-stat host localhost port 6380 overview

Print general information about a Redis instance;

实时打印出host为localhost，端口为6380，redis实例的总体信息

[root@Architect redis-1.2.6]# redis-stat port 6380 overview   ------- data ------ ------------ load ----------------------------- - childs -   keys   used-mem clients  requests      connections   1319   5.37M   103    44108021 (+44108021) 810           1319   5.38M   103    44108124 (+103)   810           1319   5.38M   103    44108225 (+101)   810           1319   5.39M   103    44108326 (+101)   810           1319   5.40M   103    44108427 (+101)   810           1319   5.41M   103    44108528 (+101)   810

redis-stat host localhost port 6380 overview

Measure Redis server latency;

输出host为localhost，端口为6380，redis服务中每个请求的响应时长

[root@Architect redis-1.2.6]# redis-stat port 6380 latency  1: 0.16 ms  2: 0.11 ms  3: 0.15 ms  4: 0.11 ms  5: 0.18 ms  6: 0.14 ms
