Installation and configuration of redis under centos7
Redis is no longer a rare thing, but it is definitely an artifact.
1 ready
1、 A computer that can connect to the Internet (this article takes centos7 as an example)
2 start installation
1、 Check if it has been installed before (ps -ef|grep redis)
Because I have installed it locally, so there is the above record, otherwise it is empty
2、 Install gcc-c++ (needed by redis compilation environment)
sudo yum install gcc-c++
3、 Download the source code locally (wget http://download.redis.io/releases/redis-the version you need.tar.gz---I downloaded 3.2.8)
I downloaded it to user/local
4、 Unzip (tar -zxvf redis-3.2.8.tar.gz)
5、 Compile
Enter redis-3.2.8 (cd redis-3.2.8)
Execute make && make install
At this time, there will be a few more files in the src directory (green in the figure below)
3 Configuration
1、 Create redis/etc and redis/bin directories under local to store configuration files and startup files respectively
2、 Copy redis-3.2.8/redis.conf to redis/etc
3、 Move the green file generated in step 5 above into redis/bin
4、 Configure redis/etc/redis.conf
Mainly revised:
bind 127.0.0.1 (comment out this line, otherwise other machines cannot connect to the redis service)
requirepass 123456789 (Let go of this line and configure your own password)
daemonize yes (redis running in the background)
5、 Start (./user/local/redis/bin/redis-server /user/local/redis/etc/redis.conf)
Note: Because it is running in the background, the redis startup diagram (startup log and other information) will not appear here
4 test
Test the connection with redis manager desktop locally

systemctl stop firewalld.service #Stop firewall
systemctl disable firewalld.service #Prohibit firewall from booting up
