2. Compilation

Redis is installed through source code, so we need to install the gcc compiler first, as well as the tcl package on which redis depends

Yum install gcc tcl

Downloading installation package

Installation completed

3. Create an installation directory

Mkdir redis

Upload the downloaded redis to the new directory, and then decompress it

Tar-xzvf redis-4.0.1.tar.gz

5. Specify the installation directory

Use PREFIX to specify the redis installation directory, make PREFIX=/home/diweikang/redis/ install

After the installation is complete, you can see that there is a bin directory in the / home/diweikang/redis directory, and in the bin directory is the redis command script

6. Configure redis as a service

Following the above steps, the startup script for redis is: / home/diweikang/redis/redis-4.0.1/utils/redis_init_script

Copy the startup script to the / etc/rc.d/init.d/ directory and name it redis

Cp / home/diweikang/redis/redis-4.0.1/utils/redis_init_script / etc/rc.d/init.d/redis

Edit the / etc/rc.d/init.d/redis file and modify the configuration so that it can be registered as a service

Vi / etc/rc.d/init.d/redis

(1) add a line after the first line of the monitor: # chkconfig: 2345 8090 if it is not added, it will prompt: service redis does not support chkconfig when registering the service

(2) the REDISPORT port remains unchanged at 6379 (note that the port name will be related to the following configuration file name)

(3) change EXEC to / home/diweikang/redis/bin/redis-server

(4) change CLIEXEC to / home/diweikang/redis/bin/redis-cli

(5) configuration file settings

Create the redis profile directory mkdir conf

Copy the redis configuration file / home/diweikang/redis/redis-4.0.1/redis.conf to the directory / home/diweikang/redis/conf and name it 6379.conf after the port number

Cp / home/diweikang/redis/redis-4.0.1/redis.conf / home/diweikang/redis/conf/6379.conf

After making the above preparations, make the following adjustments to the CONF property

CONF changed to / home/diweikang/redis/conf/$ {REDISPORT} .conf

(6) change the command opened by redis and execute it in the background.

$EXEC $CONF &

The function of & is to transfer the service to the background
