how to execute a script Rhel 7 at booting time?

Question

I am trying to execute a shell script on RHEL7.1 when the machine starts. As in ubuntu, Upstart scripts (in /etc/init/) are used to execute any scripts or to start any services at boot time, is there anything equivalent in RHEL 7.1 to upstart?

Red Hat got rid of upstart (because it was crap). It uses systemd now. — Michael Hampton, May 01 '16 at 22:56

Let's say you want to execute example.service at booting time, you'd do:

vi /etc/systemd/system/example.service

with this content:

 [Unit] 
 Description=Example 
 After=network.target 

 [Service] 
 Type=simple 
 WorkingDirectory=/var/lib/example
 ExecStart=/usr/local/bin/example --pid /var/run/example.pid --core unlimited -c /etc/example/example.ini 
 Restart=always 
 User=root
 Group=root 
 LimitNOFILE=10240 
 LimitFSIZE=infinity

 [Install] 
 WantedBy=multi-user.target

Then, just start and enable it:

systemctl start example.service
systemctl enable example.service

In my case I've got a shell script to execute, so I need to provide the apth to that shell script in ExecStart=/home/scripts/temp.sh, right? and while rebooting the shell script will get executed? – user3460393 May 02 '16 at 06:12
Yeah, that's right – sysfiend May 02 '16 at 06:52
Depending on what the script does, you may want `Type=oneshot` instead. – Michael Hampton Jan 03 '18 at 03:08

Add the scrpit in /etc/rc.d/rc.local file, The script will be automatically executed during boot.

That works in RHEL6, not 7 – sysfiend May 02 '16 at 09:47
