It can also tell you how to start redis

Default redis Configuration file installation path

6. Use make. (make yes Linux The original order , Will be looking for Makefile), stay src There is also a... Under the file Real body makefile Detailed instructions . Default installation path

7. Return to the right topic , Use it directly make command , install redis.. redis-6.2.6 Under the table of contents

Report errors gcc, Can install yum install gcc
In the use of make distclean Cleanup installation failed
After successful installation, you can see make test

8. To src Under the directory, you can ** ./redis-serve** start-up redis. （ At this time, the program has been generated ）

9. In fact, we have successfully installed it here , But we certainly don't want to use this command every time we start up in our daily development process

10. make install PREFIX=/opt/redis6

The purpose of this step is to move the executable out of , Not mixed with the source code

11. For example, we want to use service start redis . But this step certainly does not support . Back to utils below , find install_server.sh

12. First of all, let's j Add the executor to the environment variable vim /etc/profile

14. Use ./install_server.sh Prompt error , This program seems to use systemd

   This systems seems to use systemd.

modify install_server.sh file , Find the following and comment out the prompt

#bail if this system is managed by systemd
_pid_1_exe="$(readlink -f /proc/1/exe)"
if [ "${_pid_1_exe##*/}" = systemd ]
then
        echo "This systems seems to use systemd."
        echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
