2.安装：
-
解压redis：
[root@node202 ~]# cd /usr/local/soft/ [root@node202 soft]# tar -zxvf redis-7.0.11.tar.gz -
安装：
进入redis-7.0.11文件夹：
[root@node202 soft]# cd redis-7.0.11/ #安装必要类库 [root@node202 redis-7.0.11]# yum -y install gcc automake autoconf libtool make [root@node202 redis-7.0.11]# make & make install -
启动：
[root@node202 redis-7.0.11]# cd src [root@node202 src]# ./redis-server /usr/local/soft/redis-7.0.11/redis.conf打印启动日志：8789:C 11 May 2023 01:53:49.076 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 8789:C 11 May 2023 01:53:49.076 # Redis version=7.0.11, bits=64, commit=00000000, modified=0, pid=8789, just started 8789:C 11 May 2023 01:53:49.076 # Configuration loaded 8789:M 11 May 2023 01:53:49.077 * Increased maximum number of open files to 10032 (it was originally set to 1024). 8789:M 11 May 2023 01:53:49.077 * monotonic clock: POSIX clock_gettime _._ _.-``__ ''-._ _.-`` `. `_.

使用：
[root@node202 src]# ./redis-cli 127.0.0.1:6379> set foo bar OK 127.0.0.1:6379> get foo "bar" 127.0.0.1:6379>
3.配置
-
创建一个用于存储 Redis 配置文件目录（
/etc/redis）和数据目录（/var/redis）：mkdir -p /etc/redis mkdir -p /var/redis -
复制配置文件：
cp /usr/local/soft/redis-7.0.11/redis.conf /etc/redis/ -
复制编辑启动脚本：
cp /usr/local/soft/redis-7.0.11/utils/redis_init_script /etc/init.d/redisvim /etc/init.d/redis #!/bin/sh # # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem. ### BEGIN INIT INFO # Provides: redis_6379 # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Redis data structure server # Description: Redis data structure server.

设置开机自启动：
chmod +x /etc/init.d/redis #给脚本设置权限 chkconfig --add redis #添加redis服务 chkconfig redis on #设置redis服务开机启动
完结。
解决服务器Redis无法连接问题
找到你的redis配置文件，进行以下步骤修改。（本人的在/etc/redis.conf，如果找不到，直接创建一个，然后度娘一个默认的redis配置文件粘贴上去即可，启动时使用命令redis-cli +文件路径，下文会讲）
修改bind，默认为bind 127.0.0.1，将其注释(前面加个#)，如果没有找到bind 127.0.0.1或已经注释，跳过此步。
# By default Redis listens for connections from all the network interfaces
# available on the server. It is possible to listen to just one or multiple
# interfaces using the "bind" configuration directive, followed by one or
# more IP addresses.
#
# Examples:
# bind 127.0.0.1
关闭保护模式，默认为protected-mode yes,将yes修改为no，如果没有找到protected-mode yes，可以随意另起一行添加protected-mode no；或已经修改为protected-mode no，跳过此步。
# When protected mode is on and if:
#
# 1) The server is not binding explicitly to a set of addresses using the
# "bind" directive.
# 2) No password is configured.
#
# The server only accepts connections from clients connecting from the
# IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain
# sockets.
#
# By default protected mode is enabled. You should disable it only if
# you are sure you want clients from other hosts to connect to Redis
# even if no authentication is configured, nor a specific set of interfaces
# are explicitly listed using the "bind" directive.
protected-mode no
如果有需求，设置密码（没有需求则跳过），添加一行requirepass 123456，作用是设置连接密码为123456，如有需求可以修改密码
################################## SECURITY ###################################
# 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
