Question

/etc/init.d/apache2 restart

error:

There are processes named 'apache2' running which do not match your pid file which are left untouched in the name of safety, Please review the situation by hand.

Answer 1

Kill them.

kill -9 $(ps -e | grep apache2 | awk '{print $1}')

Answer 2

Before killing the process, maybe, you would like to check if the pid file path set in

/etc/apache2/apache2.conf

equals the one stated in APACHE_PID_FILE environment variable exported in the :

/etc/apache2/envvars

file.

Saving a process snapshot before proceeding to kill, would be helpful :

# top -b -n1 > /tmp/process.log

Then get the pid of apache2 with :

pidof apache2

It output the related processes id(s) e.g 4920 4919. Then kill them with :

sudo kill -9 pid

replacing pid with the process id(s) you got from the previous output.

Finally restart Apache 2 server :

sudo /etc/init.d/apache2 restart

Next time would be helpful letting others know basic things about your OS distro etc.

Hope it helps someone.
