摘要：redis常用命令小结

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

[b]2、redis-cli[/b] 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

[b]3、redis-stat[/b] 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   5.41M   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
