redis基本安装判断、启动使用方法示例
本文实例讲述了redis基本安装判断、启动使用方法。分享给大家供大家参考,具体如下:
1、Redis对否安装(安装好了会出现下面对应的代码)
[root]$whereisredis-cli redis-cli:/usr/local/bin/redis-cli [root]$ [root]$whereisredis-server redis-server:/usr/local/bin/redis-server
2、启动Redis
输入代码
redis-server& 30733:C09Dec14:45:30.876#Warning:noconfigfilespecified,usingthedefaultconfig.Inordertospecifyaconfigfileuseredis-server/path/to/redis.conf 30733:M09Dec14:45:30.879#Yourequestedmaxclientsof10000requiringatleast10032maxfiledescriptors. 30733:M09Dec14:45:30.879#Servercan'tsetmaximumopenfilesto10032becauseofOSerror:Operationnotpermitted. 30733:M09Dec14:45:30.879#Currentmaximumopenfilesis4096.maxclientshasbeenreducedto4064tocompensateforlowulimit.Ifyouneedhighermaxclientsincrease'ulimit-n'.

3.判断Redis是否启动
[root]#redis-cli-p6379 127.0.0.1:6379>ping PONG 127.0.0.1:6379>
希望本文所述对大家Redis数据库程序设计有所帮助。
