Installation
Download, extract, compile:
$wget http://download.redis.io/releases/redis-4.0.10.tar.gz
$tar xzf redis-4.0.10.tar.gz
$mv redis-4.0.10 / usr/local/redis
$cd / usr/local/redis
$make
The binaries are compiled in the src directory
$ll-a src | grep redis

Redis-server is the server program and redis-cli is the client program.
Create a service
After the binary file is compiled, in the src directory, start the Redis service with the following command:
$ln-s / usr/local/redis/src/redis-cli / usr/bin/redis
$ln-s / usr/local/redis/src/redis-server / usr/bin/redisd
Output version
$redis-version
Redis-cli 4.0.10
$redisd-version
Redis server vault 4.0.10 sha=00000000:0 malloc=jemalloc-4.0.3 bits=64 build=e53a76b77e60d5b0
At this point, your redis has been installed.
Configuration
Why should the configuration list a separate title?
This is because Redis does not maximize the optimization of security aspects, but tries to optimize high performance and ease of use as much as possible.
Redis opens port 6379 by default, which can cause any user to perform unauthorized access operations if authentication is not enabled.
So we need to do some security configuration here.
New users
Never start Redis with a user with higher privileges. If your Reidis is not secure, then your highly privileged users will become a breakthrough, causing your server to be attacked.
So we need to create a redis account, start the redis service through this account, and configure the account to disable login.
$adduser redis
$vim / etc/passwd
Redis:x:1001:1001:,:/home/redis:/usr/sbin/nologin
$chown-R redis:redis / usr/local/redis
Modify the configuration file
You are required to have a basic operation on vim.
$vim redis.conf
# modify the port around line 92
Port 7379
# Log files around line 171
Logfile / var/log/redis/redis.log
# set the snapshot file directory around line 263, and do not set it to a directory where the redis user does not have permission
Dir / usr/local/redis/
# set a password around line 500
Requirepass YOUR_PASSWORD
$mkdir / var/log/redis
$chown-R redis:redis / var/log/redis/
Configure a launcher
Redis-server is not started by the daemon by default, so we need to configure a launcher for it
.
$vim / usr/bin/goredisd
Nohup / usr/bin/redisd / usr/local/redis/redis.conf > > / var/log/redis/goredisd.log 2 > & 1 &
$goredisd
$ps-axu | grep redis
Redis 19498 0.0 0.1 145304 2580 pts/0 Sl 10:49 0:09 / usr/bin/redisd *: 7379
