Relaunch Apache automatically if inactive in CentOS 7
Few days ago I wrote about how to start/restart Apache if it is inactive in Ubuntu. Today I am going to share a bash script for CentOS 7. It is mostly the same except for few changes.
Login to your server and create apache.sh file in /opt/httpd (you can choose other dir for storing the script). Create httpd dir 1st(mkdir httpd).
This script is tested on CentOS 7 server.
#!/bin/sh
RESTART="systemctl start httpd"
SERVICE="httpd"
LOGFILE="/opt/httpd/autostart-apache2.log"
#check for the word inactive in the result of status
if systemctl status httpd | grep -q inactive
then
echo "starting apache at $(date)" >> $LOGFILE
$RESTART >> $LOGFILE
else
echo "apache is running at $(date)"
fi
If you want to log the else statement too, add >> $LOGFILE
at the end of the echo line. I personally don’t need it as it will spam the logs.
To run this script every minute via cron:
* * * * * sh /opt/httpd/apache.sh
