目录
1 下载
wget http://download.redis.io/releases/redis-6.0.9.tar.gz
2 解压
tar -xzvf redis-6.0.9.tar.gz -C ../soft3 安装
3.1 进入解压目录
[liucf@node1 soft]$ cd redis-6.0.9/
3.2 安装gcc编译环境
如果已经安装过了，那么跳过本步骤
[liucf@node1 redis-6.0.9]$ yum install gcc-c++
更新gcc：
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
yum install tcl
scl enable devtoolset-9 bash
3.3 编译并安装
sudo make
sudo make install
3.4 测试
[liucf@node1 redis-6.0.9]$ redis-server ./redis.conf

77320:M 19 Sep 2021 12:50:23.813 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
77320:M 19 Sep 2021 12:50:23.813 # Server can't set maximum open files to 10032 because of OS error: Operation not permitted.
77320:M 19 Sep 2021 12:50:23.813 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

4.2 拷贝文件至/etc/init.d
[liucf@node1 utils]$ sudo cp redis_init_script /etc/init.d/进入目录查看
[liucf@node1 init.d]$ cd /etc/init.d/
4.3 创建目录拷贝redis.conf
这个目录方便后面存放redis.conf
[liucf@node1 local]$ sudo mkdir /usr/local/redis拷贝redis.conf到 /usr/local/redis
[liucf@node1 redis-6.0.9]$ sudo cp redis.conf /usr/local/redis4.4 修改配置文件
4.4.1修改 daemonize
修改 daemonize no -> daemonize yes，目的是为了让redis启动在linux后台运行
# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
##daemonize no
##
daemonize yes4.4.2 修改工作空间目录
创建目录
[liucf@node1 redis]$ sudo mkdir /usr/local/redis/working# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /usr/local/redis/working4.4.3 修改bind使其外部可以访问
################################## NETWORK #####################################
# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all available network interfaces on the host machine.
# 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 ::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 on the
# IPv4 loopback interface address (this means Redis will only be able to
# accept client connections from the same host that it is running on).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT OUT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 0.0.0.0
# Protected mode is a layer of security protection, in order to avoid that
# Redis instances left open on the internet are accessed and exploited.
#
# 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 yes
protected-mode no4.4.4 设置redis密码
# IMPORTANT NOTE: starting with Redis 6 "requirepass" is just a compatibility
# layer on top of the new ACL system. The option effect will be just setting
# the password for the default user. Clients will still authenticate using
# AUTH <password> as usually, or more explicitly with AUTH default <password>
# if they follow the new protocol: both will work.
#
# requirepass foobared
requirepass liucf123456配置修改完毕
5 修改启动脚本文件
