For instructions regarding the manual upgrade of Apache HTTP Proxy, scroll down.

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.

1. 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

4. 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.

4. 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"

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

sc start ApacheHttpProxy

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

8. If you want 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
   
   
   1. Add the following lines to httpd.conf under <Proxy *>:
      
      AuthType Basic
AuthName "Password Required"
AuthUserFile password.file
AuthGroupFile group.file
Require group usergroup
   
   
   1. 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.

   C:\Program Files\Apache HTTP Proxy\logs\error.log

11. 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
