这篇文章主要介绍了Redis2.8配置文件中文详解,本文提供的是是Redis2.8.9的配置文件各项的中文解释,需要的朋友可以参考下
addhttps://m.qb5200.com/byhttps://m.qb5200.com/zhjhttps://m.qb5200.com/:https://m.qb5200.com/没找到本文的原文。另外，redis配置文件中文翻译https://m.qb5200.com/也翻译的不错，可以与本文对照看。两篇文章都是以Redis2.8来介绍的
在Redis中直接启动redis-server服务时,https://m.qb5200.com/采用的是默认的配置文件。采用redis-serverhttps://m.qb5200.com/xxx.confhttps://m.qb5200.com/这样的方式可以按照指定的配置文件来运行Redis服务。下面是Redis2.8.9的配置文件各项的中文解释。
#daemonizehttps://m.qb5200.com/nohttps://m.qb5200.com/默认情况下，https://m.qb5200.com/redishttps://m.qb5200.com/不是在后台运行的，如果需要在后台运行，把该项的值更改为https://m.qb5200.com/yes
daemonizehttps://m.qb5200.com/yes
#https://m.qb5200.com/当https://m.qb5200.com/redishttps://m.qb5200.com/在后台运行的时候，https://m.qb5200.com/Redishttps://m.qb5200.com/默认会把https://m.qb5200.com/pidhttps://m.qb5200.com/文件放在https://m.qb5200.com//var/run/redis.pidhttps://m.qb5200.com/，你可以配置到其他地址。
#https://m.qb5200.com/当运行多个https://m.qb5200.com/redishttps://m.qb5200.com/服务时，需要指定不同的https://m.qb5200.com/pidhttps://m.qb5200.com/文件和端口
pidfilehttps://m.qb5200.com//var/run/redis_6379.pid
#https://m.qb5200.com/指定https://m.qb5200.com/redishttps://m.qb5200.com/运行的端口，默认是https://m.qb5200.com/6379
porthttps://m.qb5200.com/6379
#https://m.qb5200.com/在高并发的环境中，为避免慢客户端的连接问题，需要设置一个高速后台日志
tcp-backloghttps://m.qb5200.com/511
#https://m.qb5200.com/指定https://m.qb5200.com/redishttps://m.qb5200.com/只接收来自于该https://m.qb5200.com/IPhttps://m.qb5200.com/地址的请求，如果不进行设置，那么将处理所有请求
#https://m.qb5200.com/bindhttps://m.qb5200.com/192.168.1.100https://m.qb5200.com/10.0.0.1
#https://m.qb5200.com/bindhttps://m.qb5200.com/127.0.0.1
#https://m.qb5200.com/设置客户端连接时的超时时间，单位为秒。当客户端在这段时间内没有发出任何指令，那么关闭该连接
#https://m.qb5200.com/0https://m.qb5200.com/是关闭此设置
timeouthttps://m.qb5200.com/0
#https://m.qb5200.com/TCPhttps://m.qb5200.com/keepalive
#https://m.qb5200.com/在https://m.qb5200.com/Linuxhttps://m.qb5200.com/上，指定值（秒）用于发送https://m.qb5200.com/ACKshttps://m.qb5200.com/的时间。注意关闭连接需要双倍的时间。默认为https://m.qb5200.com/0https://m.qb5200.com/。
tcp-keepalivehttps://m.qb5200.com/0
#https://m.qb5200.com/指定日志记录级别，生产环境推荐https://m.qb5200.com/notice
#https://m.qb5200.com/Redishttps://m.qb5200.com/总共支持四个级别：https://m.qb5200.com/debughttps://m.qb5200.com/、https://m.qb5200.com/verbosehttps://m.qb5200.com/、https://m.qb5200.com/noticehttps://m.qb5200.com/、https://m.qb5200.com/warninghttps://m.qb5200.com/，默认为https://m.qb5200.com/verbose
#https://m.qb5200.com/debughttps://m.qb5200.com/https://m.qb5200.com/https://m.qb5200.com/记录很多信息，用于开发和测试

#https://m.qb5200.com/warninghttps://m.qb5200.com/https://m.qb5200.com/只有非常重要或者严重的信息会记录到日志
loglevelhttps://m.qb5200.com/notice
#https://m.qb5200.com/配置https://m.qb5200.com/loghttps://m.qb5200.com/文件地址
#https://m.qb5200.com/默认值为https://m.qb5200.com/stdouthttps://m.qb5200.com/，标准输出，若后台模式会输出到https://m.qb5200.com//dev/nullhttps://m.qb5200.com/。

#https://m.qb5200.com/Redishttps://m.qb5200.com/调用内部函数来执行许多后台任务，如关闭客户端超时的连接，清除过期的https://m.qb5200.com/Keyhttps://m.qb5200.com/，等等。
#https://m.qb5200.com/不是所有的任务都以相同的频率执行，但https://m.qb5200.com/Redishttps://m.qb5200.com/依照指定的“https://m.qb5200.com/Hzhttps://m.qb5200.com/”值来执行检查任务。
#https://m.qb5200.com/默认情况下，“https://m.qb5200.com/Hzhttps://m.qb5200.com/”的被设定为https://m.qb5200.com/10https://m.qb5200.com/。
#https://m.qb5200.com/提高该值将在https://m.qb5200.com/Redishttps://m.qb5200.com/空闲时使用更多的https://m.qb5200.com/CPUhttps://m.qb5200.com/时，但同时当有多个https://m.qb5200.com/keyhttps://m.qb5200.com/同时到期会使https://m.qb5200.com/Redishttps://m.qb5200.com/的反应更灵敏，以及超时可以更精确地处理。
#https://m.qb5200.com/范围是https://m.qb5200.com/1https://m.qb5200.com/到https://m.qb5200.com/500https://m.qb5200.com/之间，但是值超过https://m.qb5200.com/100https://m.qb5200.com/通常不是一个好主意。
#https://m.qb5200.com/大多数用户应该使用https://m.qb5200.com/10https://m.qb5200.com/这个预设值，只有在非常低的延迟的情况下有必要提高最大到https://m.qb5200.com/100https://m.qb5200.com/。
