How to solve the error when installing redis on ubuntu

ubuntu system installation redis troubleshooting and solution

 $ wget http://download.redis.io/releases/redis-6.0.6.tar.gz  #wget命令下载redis安装文件，也可在官网下载压缩包
 $ tar -xvf redis-6.0.6.tar.gz  #将下载好的压缩包进行解压
 $ mv redis-6.0.6 /usr/local/redis 
 #把redis安装移动到/usr/local/里面，非必须
 $ cd /usr/local/redis #进入该目录
 $ make #执行make命令，等待redis安装

The following interface appears
##

$ ln -s /usr/local/redis/src/redis-cli /usr/local/bin/ #配置环境，建立软连接$ redis-cli #看是否安装成功

An error was found：Could not connect to Redis at 127.0.0.1: 6379: Connection refused

not connected> exit
I encountered a problem from the beginning when using Redis，The client cannot be opened，The reason is that the server needs to be opened first，This requires First configure

$ cp redis.conf /etc  #负责文件到etc目录$ cd /etc #进入该目录$ vi redis.conf 
#修改文件中 daemonize no 为 daemonize yes （222行）可能不一样自己找一下

$ redis-server /etc/redis.conf #开启客户端要确保服务端启动

and find that there is still an error message：Command 'redis-server' not found, but can be installed with:

sudo apt install redis-server

Looking for related issues, I found that ，just make will not work，you also need to perform a make install command

$ cd /usr/local/redis/src
$ make install
$ redis-server /etc/redis.conf#发现启动成功
