Log in to your web server as an administrator. Open the configuration file /etc/Httpd.conf. Modify the file as shown in these code blocks, depending on whether you are connecting over HTTP without authentication, or over HTTPS with authentication. HTTPD - Apache2 Web Server. Apache is the most commonly used Web server on Linux systems. Web servers are used to serve Web pages requested by client computers. Clients typically request and view Web pages using Web browser applications such as Firefox, Opera, Chromium, or Internet Explorer.

Syntax of the Configuration Files
httpd configuration files contain one directive per line. The backslash ' may be used as the last character on a line to indicate that the directive continues onto the next line. There must be no other characters or white space between the backslash and the end of the line.
Arguments to directives are separated by whitespace. If an argument contains spaces, you must enclose that argument in quotes.
Directives in the configuration files are case-insensitive, but arguments to directives are often case sensitive. Lines that begin with the hash character '#' are considered comments, and are ignored. Comments may not be included on the same line as a configuration directive. White space occurring before a directive is ignored, so you may indent directives for clarity. Blank lines are also ignored.
The values of variables defined with the Define of or shell environment variables can be used in configuration file lines using the syntax ${VAR}. If 'VAR' is the name of a valid variable, the value of that variable is substituted into that spot in the configuration file line, and processing continues as if that text were found directly in the configuration file. Variables defined with Define take precedence over shell environment variables. If the 'VAR' variable is not found, the characters ${VAR} are left unchanged, and a warning is logged. Variable names may not contain colon ':' characters, to avoid clashes with RewriteMap's syntax.

Only shell environment variables defined before the server is started can be used in expansions. Environment variables defined in the configuration file itself, for example with SetEnv, take effect too late to be used for expansions in the configuration file.
The maximum length of a line in normal configuration files, after variable substitution and joining any continued lines, is approximately 16 MiB. In .htaccess files, the maximum length is 8190 characters.
Example Apache2 Conf File
You can check your configuration files for syntax errors without starting the server by using apachectl configtest or the -t command line option.
Apache Web Server Configuration Files
You can use mod_info's -DDUMP_CONFIG to dump the configuration with all included files and environment variables resolved and all comments and non-matching <IfDefine> and <IfModule> sections removed. However, the output does not reflect the merging or overriding that may happen for repeated directives.
