Fedora 22 (15 or later) boot script

Some time ago made a website Btdog magnetic and Btdog TV Live. DHT crawlers need to consume more resources, the original server is not enough, so that they use a computer to build a server, using the FEDORA22 system. Some auto-start scripts are automatically written in Fedora22, but they are not always found. Toss it down and discover the original Fedora starting from 15, the system initialization software began to shift from Initscript to SYSTEMD mode, Originally to write boot script is generally written in rc.local inside, but now rc.local no longer exist, but Systemd still have rc-local service.

Edit/usr/lib/systemd/system/rc-local.service

　　We just need to create a new file/etc/rc.d/rc.local and then add our own script.

New rc.local　　

Touch /etc/rc.d/rc.local

Vim/etc/rc.d/rc.local

#!/bin/bash# Below is the script you need to execute

#####################################

　　Assign to executable permissions

chmod +x/etc/rc.d/rc.local

　Then use SYSTEMD to boot from

Systemctl Enable Rc-local.service

　　The prompt error is as follows:　

The unit files has a no [Install] section. They is not meant to being enabledusing systemctl.  Possible reasons for have this kind of units are:1) A unit May is statically enabled by being symlinked from another Unit ' s   . wants/or. requires/ directory.2) A Unit's purpose may is to act as A helper for some other unit which ha s   a requirement dependency on it.3) a unit may is started when needed via activation (socket, path, timer,
        
         d-bus, Udev, scripted systemctl call, ...).
           

　　At this point, we need to add the [Install] zone to the/usr/lib/systemd/system/rc-local.service to tell Systemd to start the script when the user starts or when the graphics start

　OK, then use SYSTEMD to boot from

　Then view the startup status
