linux的redis常用命令

　　Linux下redis為我們提供了豐富的命令。下面由學(xué)習(xí)啦小編為大家整理了linux下redis常用命令的相關(guān)知識，希望對大家有幫助!

　　linux的redis常用命令1、redis-benchmark

　　redis基準(zhǔn)信息，redis服務(wù)器性能檢測

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

　　100個并發(fā)連接，100000個請求，檢測host為localhost 端口為6379的redis服務(wù)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

　　99.70% <= 8 milliseconds

　　99.99% <= 9 milliseconds

　　100.00% <= 12 milliseconds

　　24274.27 requests per second

　　linux的redis常用命令2、redis-cli

　　redis-cli -h localhost -p 6380 monitor

　　Dump all the received requests in real time;

　　監(jiān)控host為localhost，端口為6380，redis的連接及讀寫操作

　　[root@Architect redis-1.2.6]# redis-cli -h localhost -p 6380 monitor

　　+OK
