httpd: Could not reliably determine the server’s fully qualified domain name, using 172.16.238.10. Set the ‘ServerName’ directive globally to suppress this message
this is error message i get when iam doing curl.
my god!! @ramashish.sharma
Tried this task around 10 times now, now the last error message i get for curl command is Could not reliably determine the server’s fully qualified domain name, using 172.16.238.10. Set the ‘ServerName’ directive globally to suppress this message…
@Inderpreet @Tej-Singh-Rana @ramashish.sharma
did all everything right. is this issue from my side or your side @Inderpreet
Hey Sasi,
You are almost done. Everytime you do this task, you end up with an error and we correct it. Now that you have exhausted all your errors and still facing issue, it means you are probably doing something wrong. I have done this task again in my personal laptop and dont see any issues. I’m able to achieve success. Now only thing is it would be good to provide a screenshot of all below commands.
-
htpasswd -c /etc/httpd/.htpasswd yousuf
chown apache:apache /etc/httpd/.htpasswd
chmod 644 /etc/httpd/.htpasswd -
cat /var/www/html/itadmin/.htaccess
AuthType Basic
AuthName “Restricted Content”
AuthUserFile /etc/httpd/.htpasswd
Require valid-user -
cat /etc/httpd/conf/httpd.conf
<Directory “/var/www/html/itadmin”>
AllowOverride AuthConfig
-
Check the httpd config file using → httpd -t [Throws any error if issue in httpd config. file]
-
Copy index.html from jump server to destination(app) server
-
systemctl restart httpd
-
Test the connection from app server:
$ curl http://localhost:8080 - [This should display default http home page]
$ curl -u : http://localhost:8080/itadmin/
Example:
curl -u yousuf:GyQkFRVNr3 http://stapp01:8080/itadmin/ - [This will display protected page contents of index.html]
This is xFusionCorp Industries Protected Directory!
- Finally upload you httpd.conf file, dont just copy/paste configuration file in here…
This error will not stop you from getting the result. It can be ignored.
Hello, Sasi
As i can see it’s a different error from above shared logs. You can follow ramashish.sharma given steps. You are near.

This is the main Apache HTTP server configuration file. It contains the
configuration directives that give the server its instructions.
See URL:http://httpd.apache.org/docs/2.4/ for detailed information.
In particular, see
URL:http://httpd.apache.org/docs/2.4/mod/directives.html
for a discussion of each configuration directive.
Do NOT simply read the instructions in here without understanding
what they do. They’re here only as hints or reminders. If you are unsure
consult the online docs. You have been warned.
Configuration and logfile names: If the filenames you specify for many
of the server’s control files begin with “/” (or “drive:/” for Win32), the
server will use that explicit path. If the filenames do not begin
with “/”, the value of ServerRoot is prepended – so ‘log/access_log’
with ServerRoot set to ‘/www’ will be interpreted by the
server as ‘/www/log/access_log’, where as ‘/log/access_log’ will be
interpreted as ‘/log/access_log’.
ServerRoot: The top of the directory tree under which the server’s
configuration, error, and log files are kept.
Do not add a slash at the end of the directory path. If you point
ServerRoot at a non-local disk, be sure to specify a local disk on the
Mutex directive, if file-based mutexes are used. If you wish to share the
same ServerRoot for multiple httpd daemons, you will need to change at
least PidFile.
ServerRoot “/etc/httpd”
Listen: Allows you to bind Apache to specific IP addresses and/or
ports, instead of the default. See also the
directive.
Change this to Listen on specific IP addresses as shown below to
prevent Apache from glomming onto all bound IP addresses.
#Listen 12.34.56.78:80
Listen 8080
Dynamic Shared Object (DSO) Support
To be able to use the functionality of a module which was built as a DSO you
have to place corresponding `LoadModule’ lines at this location so the
directives contained in it are actually available before they are used.
Statically compiled modules (those listed by `httpd -l’) do not need
to be loaded here.
Example:
LoadModule foo_module modules/mod_foo.so
Include conf.modules.d/*.conf
If you wish httpd to run as a different user or group, you must run
httpd as root initially and it will switch.
User/Group: The name (or #number) of the user/group to run httpd as.
It is usually good practice to create a dedicated user and group for
running httpd, as with most system services.
User apache
Group apache
‘Main’ server configuration
The directives in this section set up the values used by the ‘main’
server, which responds to any requests that aren’t handled by a
definition. These values also provide defaults for
any containers you may define later in the file.
All of these directives may appear inside containers,
in which case these default settings will be overridden for the
virtual host being defined.
ServerAdmin: Your address, where problems with the server should be
e-mailed. This address appears on some server-generated pages, such
as error documents. e.g. [email protected]
ServerAdmin root@localhost
ServerName gives the name and port that the server uses to identify itself.
This can often be determined automatically, but we recommend you specify
it explicitly to prevent problems during startup.
If your host doesn’t have a registered DNS name, enter its IP address here.
#ServerName www.example.com:80
Deny access to the entirety of your server’s filesystem. You must
explicitly permit access to web content directories in other
blocks below.
AllowOverride none Require all denied
Note that from this point forward you must specifically allow
particular features to be enabled - so if something’s not working as
you might expect, make sure that you have specifically enabled it
below.
DocumentRoot: The directory out of which you will serve your
documents. By default, all requests are taken from this directory, but
symbolic links and aliases may be used to point to other locations.
DocumentRoot “/var/www/html/sysops”
Relax access to content within /var/www.
<Directory “/var/www/html/sysops”>
AllowOverride AuthConfig
# Allow open access:
Require all granted
Further relax access to the default document root:
<Directory “/var/www/html”>
#
# Possible values for the Options directive are “None”, “All”,
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that “MultiViews” must be named explicitly — “Options All”
# doesn’t give it to you.
#
# The Options directive is both complicated and important. Please see
# core - Apache HTTP Server Version 2.4
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride All
#
# Controls who can get stuff from this server.
#
Require all granted
DirectoryIndex: sets the file that Apache will serve if a directory
is requested.
DirectoryIndex index.html
The following lines prevent .htaccess and .htpasswd files from being
viewed by Web clients.
<Files “.ht*”>
Require all denied
ErrorLog: The location of the error log file.
If you do not specify an ErrorLog directive within a
container, error messages relating to that virtual host will be
logged here. If you do define an error logfile for a
container, that host’s errors will be logged there and not here.
ErrorLog “logs/error_log”
LogLevel: Control the number of messages logged to the error_log.
Possible values include: debug, info, notice, warn, error, crit,
alert, emerg.
LogLevel warn
# # The following directives define some format nicknames for use with # a CustomLog directive (see below). # LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %b" common<IfModule logio_module>
# You need to enable mod_logio.c to use %I and %O
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
</IfModule>
#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a <VirtualHost>
# container, they will be logged here. Contrariwise, if you *do*
# define per-<VirtualHost> access logfiles, transactions will be
# logged therein and *not* in this file.
#
#CustomLog "logs/access_log" common
#
# If you prefer a logfile with access, agent, and referer information
# (Combined Logfile Format) you can use the following directive.
#
CustomLog "logs/access_log" combined
#
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL. You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.
#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client. The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.
#
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
“/var/www/cgi-bin” should be changed to whatever your ScriptAliased
CGI directory exists, if you have that configured.
<Directory “/var/www/cgi-bin”>
AllowOverride None
Options None
Require all granted
#
# AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.
#
#AddType application/x-gzip .tgz
#
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
#
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi
# For type maps (negotiated resources):
#AddHandler type-map var
#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
Specify a default charset for all content served; this enables
interpretation of all content as UTF-8 by default. To use the
default browser choice (ISO-8859-1), or to allow the META tags
in HTML content to override this choice, comment out this
directive:
AddDefaultCharset UTF-8
# # The mod_mime_magic module allows the server to use various hints from the # contents of the file itself to determine its type. The MIMEMagicFile # directive tells the module where the hint definitions are located. # MIMEMagicFile conf/magicCustomizable error responses come in three flavors:
1) plain text 2) local redirects 3) external redirects
Some examples:
#ErrorDocument 500 “The server made a boo boo.”
#ErrorDocument 404 /missing.html
#ErrorDocument 404 “/cgi-bin/missing_handler.pl”
#ErrorDocument 402 http://www.example.com/subscription_info.html
EnableMMAP and EnableSendfile: On systems that support it,
memory-mapping or the sendfile syscall may be used to deliver
files. This usually improves server performance, but must
be turned off when serving from networked-mounted
filesystems or if support for these functions is otherwise
broken on your system.
Defaults if commented: EnableMMAP On, EnableSendfile Off
#EnableMMAP off
EnableSendfile on
Supplemental configuration
