Docker | redis installation and testing

The purpose of this article is to familiarize yourself with the download, installation and use of redis, and prepare for the deployment of redis clusters later.

Download and install

On linux, I am in /downloadthe directory and execute the downloaded command

root@--- ~]# wget http://download.redis.io/redis-stable.tar.gz

Next, perform the following operations on the downloaded file, unzip the file, and move the file to /usr/local/redis/the directory

tar -xzf redis-stable.tar.gz 
mkdir -p /usr/local/redis
mv ./redis-stable/* /usr/local/redis/

Compile redis file

cd /usr/local/redis
make

After the command is executed make , the redis compiled redis service program redis-serverand the client program for testing will appear in the directory redis-cli. The two programs are located in the installation src directory

Start the redis service

Method 1:

./redis-server

Note that starting redis in this way uses the default configuration.

Method 2:

./redis-server ../redis.conf

Use the startup parameters to tell redis to use the specified configuration file to start using the following command.

redis.conf is a default configuration file. We can use our own configuration files as needed.

After starting the redis service process, you can use the test client program to interact with the service redis-cli . redis

Create another window to start the test client program, and then execute the following command in the new window:

cd /usr/local/redis/src
[root@--- 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> exit
[root@--- src]#

Configure Redis as a background service

Change the configuration file redis.confto configure it to start in the background.daemonize nodaemonize yesredis

Set Redis access password

redis.confFind it in the configuration file requirepass, remove the previous comment, and modify the latter password.

Common configuration file example redis.conf

#默认端口6379
port 6379

#绑定ip，如果是内网可以直接绑定 127.0.0.1, 或者忽略, 0.0.0.0是外网
bind 0.0.0.0
