I am using Ubuntu Server.

When I start apache2 everything is fine, but when enabling php5 module and restarting apache2 I get this error:

 *** Restarting web server apache2                                                                                                                                          [fail]

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#   /etc/apache2/
#   |-- apache2.conf
#   |   `--  ports.conf
#   |-- mods-enabled
#   |   |-- *.load
#   |   `-- *.conf
#   |-- conf-enabled
#   |   `-- *.conf
#   `-- sites-enabled
#       `-- *.conf
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.

# Global configuration

# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
# Do NOT add a slash at the end of the directory path.
#ServerRoot "/etc/apache2"

# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
Mutex file:${APACHE_LOCK_DIR} default

# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars

# Timeout: The number of seconds before receives and sends time out.
Timeout 300

# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
KeepAlive On

# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
MaxKeepAliveRequests 100

# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
KeepAliveTimeout 5

# These need to be set in /etc/apache2/envvars

# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
ErrorLog ${APACHE_LOG_DIR}/error.log

# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
LogLevel warn

# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,

# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.

  • Sounds like /etc/apache2/apache2.conf has an error on line 140. Can you sure the contents of that file? The contents of var/log/apache2/error.log would also be helpful. – DJ_Beardsquirt Oct 12 '14 at 11:49
  • Added! Check it out and help me, please! – Joserex65 Oct 12 '14 at 12:10
  • It's solved. But thanks. And the error.log wasn't there. Or I forgetted to press F5 when looking at it trought FTP. But thanks anyway. – Joserex65 Oct 12 '14 at 12:49

    Isn't it just sudo apt install libapache2-mod-php and it chooses the version needed? – Terrance Aug 5 '16 at 18:59

Looks like the PHP module for Apache is missing. Install it (from this SO question):

sudo apt-get install libapache2-mod-php5

    Package libapache2-mod-php5 is not available, but is referred to by another package. Ubuntu 16.04 – asologor May 20 '17 at 16:08

I solved it by running

sudo apt-get install libapache2-mod-php

and it installed the proper version "which apparently was not called libapache2-mod-php7 but libapache2-mod-php7.0... yay -_-)

I also had to remove the php5.conf from the installed mods and install as well php7.0-mysql

Now my website works again. Thanks to everyone.

    did you mean ...apt-get install...? – kevlarjacket Sep 19 '17 at 19:52

This just happened to me again, along with the php pages appearing as plain text, rather than processing. I had not use the webserver apache for some time on the computer and meanwhile ubuntu updated like two more versions. Now it is

$ cat /etc/issue
Ubuntu 16.04 LTS

So the php worked after like so:

$ sudo apt-get install lamp-server^
$ sudo a2enmod php7.0
$ sudo service apache2 restart 

The webserver was now parsing the php. But I bet there are other issues if it is now running php7.0 where as it was before running php5. Oh well.
