I am a bit puzzled about this... Apache status is showing information from 12 days ago. It's running fine and website is working. Is the status command not supposed to show current state of Apache?

netstat shows that port 80 is actually listening on 10.42.24.6
# netstat -tulpn | grep apache

tcp 0 0 10.42.24.6:443 0.0.0.0:* LISTEN 1557/apache2
Also Apache is logging requests to the access logs
I noticed this problem, because I am using systemctl status apache2 to check apache status in a new shell script I wrote... But the way this command is working, makes it useless.
I have service which was working fine with RHEL 7.5, now I have upgraded to RHEL 8 and same service is failing with below status:

THis is my Service unit placed under /etc/init.d/Service, same is done for RHEL 7.5 but there this service is working and in RHEL 8 it is not. One more thing here to note is web server is working as expected although giving me this error.

I am trying to create a service file that will allow me to automatically startup my Oracle 12C database and listener automatically on reboot. I have written the service file which contains the following:

# and starts Listener

Your startup.log and listerner.log don't have the correct permissions set up. Use the chmod command on those two files to the appropriate permissions and it should work
When i turn off my WiFi, NetworkManager kills apache2. This can be seen in '/var/log/apache/error_log':
[Sun Mar 01 13:25:55 2015] [notice] caught SIGTERM, shutting down
However, this does not happen if i turn off the WiFi manually by doing
sudo ifconfig wlan0 down
It seems NetworkManager goes to status 'inactive' when i disconnect it from the WiFi.
These are some of the contents of '/var/log/messages' around the time i turn off the WiFi:
Mar 1 13:25:52 raven NetworkManager[22393]: <info> (wlan0): device state change: activated -> disconnected (reason 'user-requested') [100 30 39]

Mar 1 13:25:53 raven NetworkManager[22393]: <warn> Connection disconnected (reason -3)
Is there a way to "uncouple" apache2 from NetworkManager so it is not killed when going offline
I have gentoo 3.10.7-gentoo-r1, i am using OpenRC (not systemd),
NetworkManager 0.9.8.8, and apache 2.2.25
Same problem here (Gentoo user for years).
Very quick solution:
As root, just type apache1 this will start apache with the same configs as the init script /etc/init.d/apache2 does. The only difference is that it will not check for a started network.
The reason why it is stopped then NetworkManager is stopped is this part of the init script:
depend() {
need net
use mysql dns logger netmount postgresql
after sshd
}
The need net part tells the script that this service requires the network to be up. On machine where NetworkManager is used and there is no network connection, through WiFi or wired networks, this condition is not given and the service is stopped automatically.
So as a second (still hacky) solution, you could just comment out this line.
I have an Eucalyptus-based cloud using Xen with 3 nodes. When I run a VM more than twice the number of physical machines in the xen cluster, the extra VMs never boot up, they always change state from pending to terminate, and the log file shows the node controller shutoff the extra VM after it check the instances number. When I manually shutdown some VM, then I can easily start up some VM exactly as the number I've shutdown.
The log shows this error:

Is this a limitation for CentOS 5.* and RedHat 5.? Is it fixed on CentOS 6.?
http://docs.vmd.citrix.com/XenServer/5.0.0/1.0/en_gb/guest.html#rhel5_limitations
"Only 3 virtual network interfaces are supported in versions below 5.2. For 5.2 and above, 7 virtual network interfaces are supported."
I opened this topic in both CentOS and Eucalyptus forums without luck:

Thanks, Leandro
The error you are seeing seems related to disk not to network (Device 2049 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected). I don't see that script on a CentOS 5.7 install I have here, so you may want to dig into that script to see if there is some obvious error.
The solution was to increase number of loop devices in CentOS 5, as detailed in the following link:
http://open.eucalyptus.com/participate/wiki/increase-number-loop-devices-centos-5
As the link is no longer valid, you have to go to archive.org or see this similar answer:
