This article mainly explains the "detailed steps of Redis installation and configuration". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn the detailed steps of Redis installation and configuration.

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

-rw-rw-r-- 1 root root 2.4K Jun 13 19:02 redisassert.h

-rwxr-xr-x 1 root root 2.6m Sep 14 12:05 redis-benchmark

-rw-rw-r-- 1 root root 29K Jun 13 19:02 redis-benchmark.c

-rw-r--r-- 1 root root 129K Sep 14 12:05 redis-benchmark.o

-rwxr-xr-x 1 root root 6.0m Sep 14 12:05 redis-check-aof

-rw-rw-r-- 1 root root 7.0K Jun 13 19:02 redis-check-aof.c

-rw-r--r-- 1 root root 38K Sep 14 12:05 redis-check-aof.o

-rwxr-xr-x 1 root root 6.0m Sep 14 12:05 redis-check-rdb

-rw-r--r-- 1 root root 68K Sep 14 12:04 redis-check-rdb.o

-rwxr-xr-x 1 root root 2.8m Sep 14 12:05 redis-cli

-rw-rw-r-- 1 root root 99K Jun 13 19:02 redis-cli.c

-rw-r--r-- 1 root root 450K Sep 14 12:05 redis-cli.o

-rw-rw-r-- 1 root root 22K Jun 13 19:02 redismodule.h

-rwxr-xr-x 1 root root 6.0m Sep 14 12:05 redis-sentinel

-rwxr-xr-x 1 root root 6.0m Sep 14 12:05 redis-server

-rwxrwxr-x 1 root root 65K Jun 13 19:02 redis-trib

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
