1. Systemctl Utility

Systemctl is a utility for controlling the systemd system and service manager; it is used it to start, restart, stop services and beyond. The systemctl status sub-command, as the name states is used to view the status of a service, you can use it for the above purpose like so:

2. Apachectl Utilities

Apachectl is a control interface for Apache HTTP server. This method requires the mod_status (which displays info about the server is performing including its uptime) module installed and enabled (which is the default setting).

On Debian/Ubuntu

The server-status component is enabled by default using the file /etc/apache2/mods-enabled/status.conf.

$ sudo vi /etc/apache2/mods-enabled/status.conf
Apache Mod_Status Configuration

On RHEL/CentOS

To enable server-status component, create a file below.

# vi /etc/httpd/conf.d/server-status.conf

and add the following configuration.

<Location "/server-status">
    SetHandler server-status
    #Require  host  localhost		#uncomment to only allow requests from localhost 
</Location>

Save the file and close it. Then restart the web server.

# systemctl restart httpd

If you are primarily using a terminal, then you also need a command line web browser such as lynx or links.

$ sudo apt install lynx		#Debian/Ubuntu
# yum install links		#RHEL/CentOS

Then run the command below to check the Apache service uptime:

$ apachectl status
Check Apache Status Using Apache2ctl
Check Apache Status Using Apache2ctl

Alternatively, use the URL below to view the Apache web server status information from a graphical web browser:

http://localhost/server-status
OR
http:SERVER_IP/server-status

3. ps Utility

ps is a utility which shows information concerning a selection of the active processes running on a Linux system, you can use it with grep command to check Apache service uptime as follows.

Here, the flag:

  • -e – enables selection of every processes on the system.
  • -o – is used to specify output (comm – command, etime – process execution time and user – process owner).
# ps -eo comm,etime,user | grep apache2
# ps -eo comm,etime,user | grep root | grep apache2
OR
# ps -eo comm,etime,user | grep httpd
# ps -eo comm,etime,user | grep root | grep httpd

The sample output below shows that apache2 service has been running for 4 hours, 10 minutes and 28 seconds (only consider the one started by root).
