Apache, problem Failed to start LSB: Apache2 web server

apache2

I use Ubuntu 16.02. When i try sudo service apache2 restart, it says:

Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.

Then I type: journalctl -xe, and request:

What is wrong? Where is an interrupt? Please help!


Solution 1:

There are two errors:

1. For some reason your /etc/apache2/envvars is missing:

  • from journalctl -xe:

    Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /etc/init.d/apache2: 1: /etc/apache2/envvars: envvars: not found
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /etc/init.d/apache2: 49: /etc/apache2/envvars: envvars: not found
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /etc/init.d/apache2: 1: /etc/apache2/envvars: envvars: not found
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /etc/init.d/apache2: 49: /etc/apache2/envvars: envvars: not found
...        
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /usr/sbin/apache2ctl: 1: /etc/apache2/envvars: envvars: not found
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /usr/sbin/apache2ctl: 49: /etc/apache2/envvars: envvars: not found

  • from systemctl status apache2.service:

    Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /usr/sbin/apache2ctl: 1: /etc/apache2/envvars: envvars: not found
Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: /usr/sbin/apache2ctl: 49: /etc/apache2/envvars: envvars: not found

In my system this file has next permissions:

$ ls -l /etc/apache2/envvars

-rw-r--r--   1 root root  1782 мар 19  2016 envvars

And its content ($ cat /etc/apache2/envvars) is:

# envvars - default environment variables for apache2ctl

# this won't be correct after changing uid
unset HOME

# for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
        SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
        SUFFIX=
fi

# Since there is no sane way to get the parsed apache2 config in scripts, some
# settings are defined via environment variables and then used in apache2ctl,
# /etc/init.d/apache2, /etc/logrotate.d/apache2, etc.
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
# temporary state file location. This might be changed to /run in Wheezy+1
export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
# Only /var/log/apache2 is handled by /etc/logrotate.d/apache2.
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX

## The locale used by some modules like mod_dav
export LANG=C
## Uncomment the following line to use the system default locale instead:
#. /etc/default/locale

export LANG

## The command to get the status for 'apache2ctl status'.
## Some packages providing 'www-browser' need '--dump' instead of '-dump'.
#export APACHE_LYNX='www-browser -dump'

## If you need a higher file descriptor limit, uncomment and adjust the
## following line (default is 8192):
#APACHE_ULIMIT_MAX_FILES='ulimit -n 65536'

## If you would like to pass arguments to the web server, add them below
## to the APACHE_ARGUMENTS environment.
#export APACHE_ARGUMENTS=''

## Enable the debug mode for maintainer scripts.
## This will produce a verbose output on package installations of web server mod                                               ules and web application
## installations which interact with Apache
#export APACHE2_MAINTSCRIPT_DEBUG=1

You can create it manually: sudo nano /etc/apache2/envvars, paste above content inside, save ctrl+o and exit ctrl+x.

2. In your system, the folder /etc/apache2/logs also missing:

  • from journalctl -xe:

    Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: (2)No such file or directory: AH02291: Cannot access directory '/etc/apache2/logs/' for main error log

  • from systemctl status apache2.service:

    Jan 11 02:30:46 aleksandr-VirtualBox apache2[8177]: (2)No such file or directory: AH02291: Cannot access directory '/etc/apache2/logs/' for main error log

This is not the default log folder, it is defined in your custom configuration, and must be created:

$ sudo mkdir /etc/apache2/logs

Solution 2:

I deleted .conf files in sites-available and did not delete the link files in sites- enabled .

Now I deleted those all files in sites-enabled

restarted apache2 server (sudo service apache2 restart)

worked for me

hope this might help someone :)

Solution 3:

I had the same problem. I got the same error with sudo service apache2 restart and ran sudo systemctl status apache2.service and the red line was Failed to start LSB: Apache2 web server.

Solution

run the bellow command:

sudo apache2ctl configtest

It'll check for errors (Syntax errors I think) and then you can debug the error.

Solution 4:

Try these commands: 

sudo a2dismod mpm_event
sudo a2enmod mpm_prefork

Then restart apache2 service.
