Run a script at boot time in CentOS 7

By default /etc/rc.local and /etc/rc.d/rc.local are no longer executable in CentOS7 with the new systemd-changes. Follow the below steps to make the script /root/g.sh run at boot time:

1. chmod +x /etc/rc.d/rc.local
2. chmod +x /root/g.sh
2. Mention your script at the bottom of the file /etc/rc.local (/etc/rc.local is a symlink to /etc/rc.d/rc.local)as below :

sh /root/g.sh

Restart and check 🙂

Get notification after every successful backup from BackupPC

Edit the configuration in BackupPC is as below :

Edit config –> Backup Settings –> User commands -> DumpPostUserCmd as
/theg/email.sh $xferOK $host $type $client $hostIP $share $XferMethod $sshPath $cmdType
where /theg/email.sh is the custom script.

Below are the contents of the email.sh script :

 

#!/bin/bash
# script to send simple email
# Email To ?

# Email text/message
EMAILMESSAGE=”/tmp/emailmessage.txt”

# Grab the status variables
xferOK=$1
host=$2
type=$3
client=$4
hostIP=$5
share=$6
XferMethod=$7
sshPath=$8
cmdType=$9

# Check if backup succeeded or not.
if [[ $xferOK == 1 ]]; then
        STATUS=”SUCCESS”
else
        STATUS=”FAILED”
fi

# email subject
SUBJECT=”[BackupPC] $STATUS for host: $client”

# Email text/message
echo “Filesystem backup for $host $STATUS” > $EMAILMESSAGE
echo “” >>$EMAILMESSAGE
