It’s very common to automate application startup in rc.local on Linux systems.
Was testing Red Hat 7.2 (Maipo), and found that apps was’t started.
Found this on some Red Hat blog:
“Systemd is a system and service manager for Linux operating systems. It is designed to be backwards compatible with SysV init scripts, and provides a number of features such as parallel startup of system services at boot time, on-demand activation of daemons, support for system state snapshots, or dependency-based service control logic. In Red Hat Enterprise Linux 7, systemd replaces Upstart as the default init system.”
On default /etc/rc.local comes useful info:
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
# Please note that you must run ‘chmod +x /etc/rc.d/rc.local’ to ensure
# that this script will be executed during boot.
Then, this ‘chmod’ turns rc.local enable during system startup.
To familiarize this new feature:
[root@somesystem~]# systemctl status rc-local
