Redis安装-CentOs7

官方地址

确保gcc已经安装

$ yum list installed | grep gcc
$ yum install gcc

下载、提取和编辑Redis:

$ wget http://download.redis.io/releases/redis-4.0.8.tar.gz
$ tar xzf redis-4.0..tar.gz
$ cd redis-4.0.
$ make MALLOC=libc
$ make test

运行Redis并放置到后台运行：

[root@localhost redis-4.0.]# src/redis-server

Redis must be restarted after THP is disabled.

使用内置客户端与Redis交互:

[root@localhost redis-4.0.]# src/redis-cli
127.0.0.1:> set foo bar
OK
127.0.0.1:> get foo
"bar"
127.0.0.1:> 

为了使Java代码能够连接到Redis服务器需要设置Redis密码和bind：

编辑redis.conf文件：

[root@localhost redis-4.0.]# find / -name redis.conf               #查找redis.conf文件
/opt/redis-4.0./redis.conf
[root@localhost redis-4.0.]# vi redis.conf                         #编辑redis.conf文件

# Require clients to issue AUTH <PASSWORD> 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).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
# requirepass foobared
requirepass 123456                                                   #设置密码

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 lookback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#bind 127.0.0.1                                                        #注释后redis会监听所有网络接口的连接请求

redis常用命令：

[root@localhost redis-4.0.]# src/redis-server redis.conf &            #后台运行redis server

[root@localhost redis-4.0.]# src/redis-cli                            #运行redis命令行接口
127.0.0.1:> auth 123456                                            #认证
OK
127.0.0.1:> keys *                                                 #列举

127.0.0.1:> set qqq 12345

127.0.0.1:> get qqq

127.0.0.1:> del qqq
