事项Redis配置需要注意的7个要点(redis配置注意)

Redis提供了一种高性能的键值存储,可以帮助我们在Web应用开发中存储信息。本文将将介绍七个Redis配置的需要注意的要点,给开发者带来更多的灵活性。

1.设置Redis密码:使用密码可以提高Redis的安全性,可以通过在配置文件中设置“requirepass”来设置Redis的密码。例如:

“`# Require clients to issue AUTH before processing any other

# commands. 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).

#

# requirepass foobar


2.调整maxmemory设置:Redis可以将超过maxmemory限制的数据存储在硬盘上,可以使用```config set maxmemory```命令来调整maxmemory设置。这是一个必须要设置的选项,它指定Redis可用的最大内存量。

3.设定appendonly参数:这是一项强制性配置参数,可以防止Redis遭到意外断电或重启之后的数据丢失。可以将它设置为’yes’,使Redis在执行每个写操作时进行日志记录:

# appendonly

appendonly yes


4.设置数据库文件存储目录:可以使用```dir```命令来确定数据库的文件存储目录。它的值可以是由斜杠(/)分隔的绝对路径,也可以是相对路径:

# The working directory.

#

# The DB will be written inside this directory.

#

# The Append Only File will also be created inside this directory.

#

# Note that you must specify a directory here, not a file name.

dir ./


5.调整maxclients:maxclients 参数定义了Redis服务器可以接受的最大客户端连接数。通过调整maxclients参数来限制对服务器的访问。例如:

# Set the max number of connected clients at the same time. By default

# this limit is set to 10000 clients, however if the Redis server is not

# able to configure the process file limit to allow for the specified limit

# the max number of allowed clients is set to the current file limit

# minus 32 (as Redis reserves a few file descriptors for internal operations).

#

# Once the limit is reached Redis will close all the new connections sending

# an error ‘max number of clients reached’.

#

# maxclients 10000


6.对于新特性,调节latency-monitor参数:latency-monitor参数可以调节redis对延迟监控的灵敏度。它可以帮助我们及时发现潜在问题并快速响应:

# set latency-monitor threshold.

#

# latency-monitor will log slow commands into redis log file.

#

# latency-monitor-threshold-ms is the number of milliseconds to

# execute the command before logging the warning.

#

# latency-monitor-threshold-percent is the percentage of slow

# requests that must occur before a warning is logged.

#

# latency-monitor-threshold-ms 10

# latency-monitor-threshold-percent 0.05


7.设置数据的备份、恢复选项:需要设置备份和恢复相关的参数,这样可以在发生灾难时减少损失。Redis可以使用RDB文件(通过save或者bgsave命令来保存),以及AOF(append only file)文件来完成完整备份。可以使用下面的配置来设置数据的备份和恢复:

# Save the DB on disk:

# save

# Will save the DB if both the given number of seconds and the given

# number of write operations agnst the DB occurred.

#

# In the example below the behaviour will be to save:

# after 900 sec (15 min) if at least 1 key changed

# after 300 sec (5 min) if at least 10 keys changed

# after 60 sec if at least 10000 keys changed

#

# Note: you can disable saving completely by commenting out all “save” lines.

#

# It is also possible to remove all the previously configured save

# points by adding a save directive with a single empty string argument

# like in the following example:

#

# save “”

save 900 1

save 300 10

save 60 10000


以上就是关于Redis配置的简要介绍,了解了这七个要点,开发者可以更加灵活地使用Redis。在配置Redis时,一定要注意以上七点,这对于保障Redis的安全性和可靠性来说至关重要。
