This article mainly explains "how to install and configure redis in CentOS". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to install and configure redis for CentOS.

Refer to the operation guide provided on redis's official website. The official website address is https://redis.io/download, and there is a download and installation method at the bottom.

Create a directory to download the zip file

Wget https://download.redis.io/releases/redis-6.2.4.tar.gz

Decompression

Tar xzf redis-6.2.4.tar.gz

Go to the folder directory and compile (Note: there is a redis description file "README.md" in this directory, please have time to learn about it)

Cd redis-6.2.4

1. Compile

Make

If the compilation succeeds, start the service directly for verification.

Note: if you do not install the compilation tool, you will get an error. You need to install the compilation tool and delete the error file generated by the redis compilation. The method of installing compilation tools

Yum install gcc

Delete

Make distclean

two。 Verify compilation

Go to the "src" directory and run the "redis-server" file

Cd src

. / redis-server

1. Install redis

The path can be customized, and if you do not carry the "PREFIX" parameter, redis will be installed in the "/ usr/local/bin" directory.

Make install PREFIX=/opt/xxx/redis

two。 Set environment variabl

Vi / etc/profile

Append the environment variable at the end, and the directory is the same as the directory set by redis.

Export REDIS_HONE=/opt/xxx/redis

Export PATH=$PATH:$REDIS_HOME/bin

Make the environment variable effective

Source / etc/profile

3. Create a redis instance

A server can create multiple redis processes with different port numbers.

Go to the "utils" directory (in the extracted redis directory).

Create an instance of redis using the script file provided by redis

Cd utils

. / install_server.sh

Note:

The following error is resolved by modifying the "install_server.sh" file.

Vi install_server.sh

Comment out the following areas (version 6.2.4, around line 76)

The instance was created successfully. The corresponding information of the instance can be seen in the corresponding directory. Multiple instances can be created, but the port number cannot be the same.
