wget https://download.redis.io/releases/redis-6.0.8.tar.gz

2 、 Move the compressed package location
We usually put the installation package of the program in opt Under the table of contents , This is the directory where the additional software is installed for the host , So we will move the downloaded installation package to opt Under the table of contents , And extract the .

mv redis-6.0.8.tar.gz /opt
1
Get into opt Folder

cd /opt

3、 Unzip the file
Execute this command on the... We just downloaded redis Compress the package to decompress

tar -zxvf redis-6.0.8.tar.gz

Other decompression commands

tar –xvf file.tar // decompression tar package  
tar -zxvf file.tar.gz // decompression tar.gz  
tar -jxvf file.tar.bz2   // decompression tar.bz2  
tar –Zxvf file.tar.Z // decompression tar.Z  

4、 Enter the extracted file
cd redis-6.0.8

5、 Basic environment installation
because redis yes c Written , So we need to install c Language environment , without gcc Environmental Science , The following commands need to be executed .

yum install gcc-c++ tcl

In some cases, this step is performed directly

make
make install

mak:
If the following error occurs after use , Because redis6 The above version should use gcc7

 

upgrade gcc

yum install centos-release-scl

yum install devtoolset-7-gcc*

scl enable devtoolset-7 bash

When the upgrade is complete , Perform the following make distclean Clear the files that failed to compile , And then again make, This is a success

 

make install：

 

6. Copy redis Default configuration file
The default installation path is generally usr/local/bin, Let's go into this directory .

In order to prevent unnecessary trouble caused by frequent modification of the configuration file , We need to copy the configuration file , Future modifications are only for the copied configuration file

mkdir config # Create folder
cp /opt/redis-6.0.8/redis.conf config # take /opt Under the table of contents redis Copy the configuration file to config Under the table of contents
 

Subsequent operations are based on this configuration file

7、 Set to start in the background
redis It is not started in the background by default , We're going to modify the configuration file , Change to run in the background

vim config/redis.conf 

take daemonize no Change it to yes Can .
tip : You can click the slash and enter keywords for global search

 

Daemon (daemon) It's a special kind of process that runs in the background , Used to perform specific system tasks . Many daemons start when the system boots , And keep running until the system is shut down . Others start only when they need to , Finish the task automatically

8、 start-up
redis-server config/redis.conf
 

Check the process to determine whether the startup is successful

ps -fe | grep redis

 

Test connection

redis-cli -p 6379
