A brief introduction to redis, the installation and configuration of redis source code, and the installation and mounting of docker

1. Get to know Redis

Redis Introduce
Redis（Remote Dictionary Server ), Remote dictionary service , It's an open source , Use C Language writing 、 Support network 、 Log type that can be memory based or persistent 、Key-Value database , And provide multilingual API.

2、 Single thread worker, Serialization 、 Atomic manipulation .
3、IO Model （epoll）, Support high concurrency .
4、kv Model ,v With type structure .
5、 Have local methods , Computing moves to data .

Linux install

1） Download the source code

wget https://github.com/redis/redis/archive/7.0.0.tar.gz

2） decompression

tar -zvxf 7.0.0.tar.gz

3. Mobile directory
   In general, I will redis Put the directory in /usr/local/redis Catalog .

mv redis-7.0.0 /usr/local/redis

4) compile

make && make install

5） start-up server

./src/redis-server

6. Start client

./src/redis-cli

You can also specify IP And port

 ./src/redis-cli -h 123.57.206.19 -p 6379 

7） Specify profile

./src/redis-server ./redis.conf 

If external IP visit , Please amend as follows


Specify the modified configuration file , Start again , Just ok 了

8） Set boot up
8.1 Write startup scripts （linux Power on meeting Execute the files in this directory ）
hold redis The installation directory utils Under the redis_init_script File copy to /etc/init.d/redis

cp /usr/local/redis/utils/redis_init_script /etc/init.d/redis

8.2 modify redis file

cd /etc/init.d
# Modify script execution permissions 
chmod 777 redis 
# edit redis file 
vim /etc/init.d/redis

Specify your native binary file path and configuration file path

8.3 Test startup

/etc/init.d/redis  start

8.4 Set up Redis Boot up

#centos
# Set boot up 
systemctl enable redis.service 
# Remove start 
systemctl disable redis.service

#ubuntu
apt install sysv-rc-conf
# Set boot up 
sysv-rc-conf redis on
# Remove start 
sysv-rc-conf redis off

Docker install （ recommend ）

1） start-up server

# install docker
yum install docker 

docker run -d -p 6379:6379  --name redis01 redis

mount , if necessary

docker run -p 6379:6379 --name redis01 --restart=always -v /root/redis/redis.conf:/etc/redis/redis.conf -v /root/redis/data:/data -d redis redis-server /etc/redis/redis.conf

2） Start client

docker run -it --network host --rm redis redis-cli -h 127.0.0.1 -p 6379 --raw
