redis install :

First prepare the environment and you want to install redis Version of , I used it here CentOS7.7, Virtual machines use VMware15.5,redis The use of 6.0.6 edition . good , Don't talk much , Start installation .

1, I used wget How to download redis, If your linux Not installed on , Then execute the following command yum install -y wget

2, Execute download redis The order of wget http://download.redis.io/releases/redis-6.0.6, This command allows you to download files to any directory where you execute them , I downloaded it to /usr/local Under the , And then use tar -zxvf Unzip the downloaded file .

3, because redis yes c Language development , So you need to download c The compiler gcc, The order is as follows :yum install -y gcc*, Note here , install redis6, Default downloaded gcc The version is not enough , It has to be 5.3 above ,gcc -v You can view the version .

So continue with the following upgrade command yum -y install centos-release-scl && yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils && scl enable devtoolset-9 bash

4, Enter the redis file , My path here is /usr/local/redis-6.0.6, perform make && make install Installation , If the following interface appears, the installation is successful . If the installation fails halfway , You need to perform make distclean, Clean up before continuing with the installation .

      

 

 

 redis To configure :

1, Turn off firewall :systemctl stop firewalld, And set the boot will not automatically start :systemctl disable firewalld, It can be done by systemctl status firewalld Check the status of the firewall , The following shows that the shutdown is successful :

2, close linux System security verification mechanism :vim /etc/selinux/config take SELINUX Property to disabled, then reboot restart . Use sestatus Command view , If the state is disabled It indicates that the shutdown is successful .

3, modify redis Installation directory redis.conf The following properties of , take bind 127.0.0.1 It is amended as follows bind Actual ip, take protected-mode yes Change it to protected-mode no( Turn off the protection mechanism ), take daemonize no Change it to daemonize yes( Set the startup mode to background startup ).

4, Set boot up :vim /etc/systemd/system/redis.service, The contents are as follows , Note that my installation path is /usr/local/redis-6.0.6, If you are not installed in this path , Please make relevant modifications .

[Unit]
Description=redis-server
After=network.target
[Service]

ExecStart=/usr/local/redis-6.0.6/src/redis-server /usr/local/redis-6.0.6/redis.conf
PrivateTmp=true
[Install]
WantedBy=multi-user.target 

Then execute the following command :systemctl daemon-reload、systemctl start redis.service、systemctl enable redis.service

The service operation command is as follows :

systemctl start redis.service   # start-up redis service

systemctl stop redis.service   # stop it redis service

systemctl restart redis.service   # Restart the service

systemctl status redis.service   # View the current status of the service
