Install Apache HTTP Proxy (6.x)

Issue

  • Use Apache HTTP Proxy to distribute virus signature database and program module updates to client workstations and reduce Internet traffic generated by your network.
     
  • Use Apache HTTP Proxy to distribute ESET product installation packages to the ESET Remote Administrator Agent (ERA Agent).
     
  • Apache HTTP Proxy replaces the mirror server functionality from ESET Remote Administrator 5.x. Mirror Tool is available in ERA 6.x as an alternative especially for offline environments.

Details

You can install Apache HTTP Proxy on your network to automatically distribute virus signature database updates and program component updates to client workstations. This arrangement allows for an additional layer of security—clients that are protected by a firewall and/or cannot download updates directly from ESET servers can download normal updates from a protected server configured to communicate securely with ESET servers. This arrangement limits exposure to threats for client workstations. For client computers on your network to receive updates from Apache HTTP Proxy, their update settings must be edited. 

It is recommended to install Apache HTTP Proxy when more than 37 workstations are managed on your network by ESET Remote Administrator.

Currently, setting up Apache HTTP Proxy is the primary method for caching virus signature database update files. Users who attempt to set up a local repository on the ESET Remote Administrator Server may receive the following error:

  • "Error: CRepositoryModule [Thread d4c]: GetFile: Object 'https://plgli2sm01/Repo//info.meta'not found".

Until this option is supported in a future version of ESET Remote Administrator, the instructions in this article are recommended.

Solution

Before you begin

If you already have ERA Server installed, follow the instructions below and then continue to the section create a policy for clients.

  • The steps shown here will install Apache HTTP Proxy, to create an ESET Mirror on a Client, perform these steps on a client workstation.
     
  • We recommend Method I for most users, use Method II if Method I fails, or you want to install HTTP proxy manually.

Additional documentation available

Before you install Apache HTTP Proxy, we recommend that you review the text documentation (INSTALL.txt) that is included when you download Apache HTTP Proxy. You can find this documentation in the ApacheHttp folder after you have extracted it.

  1. On the server where you want to install Apache HTTP Proxy, click the link below to download the Apache HTTP Proxy installer file:

    Download Apache HTTP Proxy

  2. Use a tool such as WinZip or 7Zip to extract the .zip file that you downloaded in step 1 to the directory C:\Program Files\Apache HTTP Proxy.

  3. Open an administrative command prompt and type the following commands in the order shown below to install Apache HTTP Proxy:

CD C:\Program Files\Apache HTTP Proxy\bin
httpd.exe -k install -n ApacheHttpProxy

  1. Navigate to C:\Program Files\Apache HTTP Proxy\conf, locate the httpd.conf file and open it using a text editor such as Notepad.

    When upgrading, original httpd.conf configuration cannot be applied because of presence of new settings. To apply custom changes (if any), open your original, backed-up httpd.conf file and append them to the new httpd.conf manually.
     
  2. At the bottom of the .conf file, add the following lines:

ServerRoot "C:\Program Files\Apache HTTP Proxy"
DocumentRoot "C:\Program Files\Apache HTTP Proxy\htdocs"
<Directory "C:\Program Files\Apache HTTP Proxy\htdocs">
 Options Indexes FollowSymLinks
 AllowOverride None
 Require all granted
</Directory>
CacheRoot "C:\Program Files\
Apache HTTP Proxy\cache"

  1. Open an administrative command prompt and type the following command to start the Apache HTTP Proxy service.

sc start ApacheHttpProxy

  1. To verify that the Apache HTTP Proxy service is running, press the Windows key + R, type Services.msc and make sure that the ApacheHttpProxy service is started. Select the service and click Stop before you continue to step

  1. If you wish to configure a username and password, navigate back to C:\Program Files\Apache HTTP Proxy\conf, open httpd.conf using a text editor such as Notepad and then follow the steps below to configure a username and password for Apache HTTP Proxy.
    1. Verify the presence of the following modules loaded in httpd.conf:

      LoadModule authn_core_module modules/mod_authn_core.dll
      LoadModule authn_file_module modules/mod_authn_file.dll
      LoadModule authz_groupfile_module modules/mod_authz_groupfile.dll
      LoadModule auth_basic_module modules/mod_auth_basic.dll

       
    2. Add the following lines to httpd.conf under <Proxy *>:

      AuthType Basic
      AuthName "Password Required"
      AuthUserFile password.file
      AuthGroupFile group.file
      Require group usergroup

       
    3. Open an administrative command prompt and type the following commands to define your password for Apache HTTP Proxy:

      CD C:\Program Files\Apache HTTP Proxy\bin
      htpasswd.exe -c ..\password.file username
       
      You will be prompted to define the password that you want to use for Apache HTTP Proxy, type your new password into the command prompt and press Enter.

    4. In the folder C:\Program Files\Apache HTTP Proxy, create a new text file named group.file with the following contents:

      usergroup:username
       
  2. Press the Windows key + R, type Services.msc select the ApacheHttpProxy service and click Start.

  3. Test the connection to HTTP Proxy by accessing the following URL in your browser:

    http://localhost:3128/index.html

    When troubleshooting, see the following file to find errors:

    C:\Program Files\Apache HTTP Proxy\logs\error.log
     
  1. Continue to Part II below to create a policy that will configure client computers and ESET Remote Administrator Agent to download updates and other files from Apache HTTP Proxy.
     

Manual upgrade of Apache HTTP Proxy

  1. Back up the following files:
    • c:\Program Files\Apache HTTP Proxy\conf\httpd.conf
    • c:\Program Files\Apache HTTP Proxy\password.file
    • c:\Program Files\Apache HTTP Proxy\group.file
  2. Stop the ApacheHttpProxy service by opening an administrative command prompt and executing the following command:

    sc stop ApacheHttpProxy

  3. Download the Apache HTTP Proxy installer file and extract its content to the directory of c:\Program Files\Apache HTTP Proxy\ overwriting the existing files

    Download Apache HTTP Proxy

  4. Navigate to c:\Program Files\Apache HTTP Proxy\conf\, right-click httpd.conf, from the context menu select Open with > Notepad.

  5. Add the following code at the bottom of that .conf file:

    ServerRoot "C:\Program Files\Apache HTTP Proxy"
    DocumentRoot "C:\Program Files\Apache HTTP Proxy\htdocs"
    <Directory "C:\Program Files\Apache HTTP Proxy\htdocs">
     Options Indexes FollowSymLinks
     AllowOverride None
     Require all granted
    </Directory>
    CacheRoot "C:\Program Files\Apache HTTP Proxy\cache"
     
  6. In case you set a username/password authentication to access your Apache HTTP Proxy earlier (step no. 8 in the installation section above), then replace the following block of code:

    <Proxy *>
    Deny from all
    </Proxy>


    with this one (it is supposed to be found in your backed-up httpd.conf file):

    <Proxy *>
    AuthType Basic
    AuthName "Password Required"
    AuthUserFile password.file
    AuthGroupFile group.file
    Require group usergroup
    Order deny,allow
    Deny from all
    Allow from all
    </Proxy>

    • In case you had any other custom modifications in the httpd.conf file of your previous installation of Apache HTTP Proxy, then you can copy over those modifications from the backed-up httpd.conf file to the new (upgraded) httpd.conf file.
  7. Save the changes and Start the the ApacheHttpProxy service  by executing the following command in an administrative command prompt:

    sc start ApacheHttpProxy

  8. Test the connection to HTTP Proxy by accessing the following URL in your browser:

    http://localhost:3128/index.html


Configure policy settings for client computers

Policy settings can be applied in existing policies

  • In these instructions, we create new policies that define the location of Apache HTTP Proxy to client computers and ESET Remote Administrator Agents to ensure that settings are applied to all client computers.
  • If you have existing policies that apply to all agents and computers, you can apply these changes in those policies rather than creating new ones. For example, if you selected Apache HTTP Proxy using the ERA Installation Wizard, you can apply the Remote Administrator Agent - HTTP Proxy Usage policy. 
  1. Open ESET Remote Administrator Web Console (ERA Web Console) in your web browser and log in.

  2. Click Admin  → PoliciesPolicies New.
