深入浅出掌握Redis配置一览表(redis配置查看)

Redis作为高性能的内存key-value数据库,是网络中实时处理和存储数据的首选方案。它的运行依赖于其参数配置信息,要把Redis配置好,对于熟悉Redis技术的人来说是比较简单的,不熟悉Redis技术的人则显得困难重重。为了能够帮助大家正确理解Redis的配置,今天就来聊聊Redis的常见配置一览表。

**1.网络配置**

Redis默认的通信端口是6379,最常用的配置是bind 127.0.0.1,表示只能本机访问,如果要在多台机器之间通信,就需要将bind设置为0.0.0.0,使其可以从任何IP的机器访问操作Redis数据库,例如:

#bind 127.0.0.1
bind 0.0.0.0

**2.安全配置**

Redis数据库还有一些安全性方面的配置,可以限制最大客户端连接数,限制IP或者IP段访问等,最常用的安全配置信息如下:

# Set the max number of connected clients at the same time. By default
# this limit is set to 10000 clients can be connected at the same time.
# maxclients 10000
# Require clients to issue AUTH before processing any other
# command. This might be useful in environments in which you do not trust
# others with access to the host running redis-server.
#
# This should stay commented out for backward compatibility and because most
# people do not need auth (e.g. they run their own servers).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second agnst a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
# requirepass foobared

**3.日志配置**

Redis启动时,会将信息和错误打印出来,日志配置可以决定这些打印信息的输出位置,最常用的是配置日志追加模式,可以将日志信息追加到指定的文件,例如:

# Append log file name.
logfile /var/log/redis/redis.log

# The filename where the Append-Only File is created if AOF is enabled.
# Default is "appendonly.aof"
appendfilename appendonly.aof

**4.性能配置**

Redis的性能可以由配置文件中的几个参数直接影响到,比如内存配置、字符串缓存等,一般来说我们要根据项目实际需求,根据机器的配置,灵活调整这些参数。合理配置性能参数,可以提升Redis的性能和服务质量,例如:

# Set the max memory limit for the max memory policy.  Accepted values are
# 'noeviction' or an integer representing bytes. If you specify a max
# memory limit without a max memory policy Redis will act as if 'noeviction'
# was set.
#
# Default is 0, which means retrieve data in a first-in first-out order.
# maxmemory 500mb

以上就是关于Redis配置一览表的大致介绍,通过对配置文件根据实际情况进行恰当调整,可以有效的提升Redis的效率和服务质量,非常有必要把握配置的重要性。
