Detailed tutorial on installing redis on Linux

Official website tutorial ：https://redis.io/docs/getting-started/installation/install-redis-from-source/

One 、 download Redis

This allows you to view redis The latest version ：https://github.com/redis/redis-hashes

From you to Redis Download the website to get the latest stable version Redis The source file , Please run ：

wget https://download.redis.io/redis-stable.tar.gz

Two 、 Decompression and compilation

To compile Redis, First of all tar decompression , Switch to the root directory , And then run make：

tar -xzvf redis-stable.tar.gz
cd redis-stable
make

If the compilation is successful , Will you be in src Found several in the directory Redis Binary , Include ：

• redis-server：Redis The server itself
• redis-cli： Is with the Redis Dialog command line interface utility .

3、 ... and 、 Install binaries

Please run ：

cd redis-stable
yum install gcc-c++
make install

The default installation path is ：/usr/local/bin

After installation , You can start by running Redis

redis-server

Although it started at this time , But only local clients can connect , And it's not running in the background , When we close the startup interface, we can't connect , So you need to modify some configurations ！

Four 、 Modify the configuration file

1. The first step is , Copy one redis.conf File to user/local/bin Under the table of contents , Here I have created a new folder for storing config, Copy here is for startup , We can specify this configuration file to start .

It can also be understood as ： To build a pseudo cluster redis To prepare for , Is through a machine , Start multiple machines at the same time redis. If you don't plan to build a pseudo cluster redis, This step is completely unnecessary .

2. Modify the configuration file

I copied the configuration file to user/local/bin Under the table of contents , Without setting up a pseudo cluster , Normally we modify /opt/redis-stable/ Under the config Configuration file , You will find it here by default when starting .

（1） modify peotected-mode

 modify peotected-mode yes
 Change it to ：protected-mode no.
#protected-mode Parameter is used to disable Internet access redis, If enabled , Only through localhost ip (127.0.0.1) visit Redis

（2） close bind 127.0.0.1

Comment out bind 127.0.0.1, Or modify bind 0.0.0.0, To allow all ip Address access

（3）redis It is not started in the background by default , modify daemonize by no

5、 ... and 、 start-up Redis

1. Start by specifying a configuration file redis

2. Use redis-cli Client connection test

3. see redis Whether the process of

One of the processes is server The process of , One is cli The process of , When the client returns , The process disappears .

4. close Redis service

/usr/bin/redis-cli shutdown # close redis service 

Or enter the client to execute shutdown close

Check again to see if the process exists

5. see redis edition

6、 ... and 、 Test performance

redis-benchmark It's a stress testing tool !
Official performance testing tool !

redis The basic commands for performance testing are as follows ：

redis-benchmark [option] [option value]

[option] [option value]： for example （key value In the form of ）：

redis-benchmark -n 10000

The following figure is provided by rookies , because redis Constantly updating , The default values in the figure below may not be up-to-date .

Let's simply test :

The host to 127.0.0.1, The port number is 6379, The order to be executed is set,get, The number of requests is 100000,100 Two concurrent connections , adopt -q Parameter makes the result show only the number of requests executed per second .

redis-benchmark -h localhost -p 6379 -t set,get -c 100 -n 100000 -q

If not -q：
