Linux - Set Up the Desktop for HTML Access

To support HTML Access, you must install Apache Tomcat, the nginx package, and the HTML Access warball on the Linux-based desktop. Follow the procedure described in this article for your Linux distribution.

Set Up an Ubuntu Desktop for HTML Access

1. Install the Apache Tomcat software.

   sudo apt-get install tomcat9

2. Install the nginx package, if it is not already installed on the Ubuntu system.

   sudo apt-get install nginx

3. Edit the /etc/nginx/conf.d/vmwvadc.conf configuration file so that it includes the following contents.

   server {
       listen 443 ssl;
       listen [::]:443 ssl;
    
       ###Enable https
       ssl_certificate /etc/vmware/ssl/rui.crt;
       ssl_certificate_key /etc/vmware/ssl/rui.key;
       ssl_protocols TLSv1.1 TLSv1.2;
       ssl_ciphers !aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH+AES:ECDH+AES:RSA+AES;
    
       access_log /var/log/nginx/nginx.vadc.access.log;
       error_log /var/log/nginx/nginx.vadc.error.log;
    
       ###Add security settings
       proxy_cookie_path / "/; SameSite=Lax; HTTPOnly; Secure";
       add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
       add_header X-XSS-Protection "1; mode=block";
    
       ###Enable user certificate(smartcard) authentication
       #ssl_verify_client optional;
       #ssl_client_certificate /etc/vmware/ssl/trustCerts.pem;
    
       location /broker {
           ###Forward user certificate
           #proxy_hide_header SSL-CLIENT-VERIFY;
           #proxy_hide_header X-SSL-CERT;
           #proxy_set_header SSL-CLIENT-VERIFY $ssl_client_verify;
           #proxy_set_header X-SSL-CERT $ssl_client_cert;
    
           proxy_pass https://localhost:8443;
           proxy_ssl_certificate /etc/vmware/ssl/rui.crt;
           proxy_ssl_certificate_key /etc/vmware/ssl/rui.key;
    
           proxy_set_header Host $host:$server_port;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       }
    
      ###Enable Web Client
      location /portal/webclient {
          proxy_pass http://localhost:8080/portal/webclient;
          proxy_redirect http://$host:$server_port/ https://$host:$server_port/;
          proxy_set_header Host $host:$server_port;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          add_header Content-Security-Policy "default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self' 'unsafe-inline';font-src 'self' data:;img-src 'self' data: blob:;media-src 'self' blob:;connect-src 'self' wss:;frame-src 'self' blob:;child-src 'self' blob:;object-src 'self' blob:;frame-ancestors 'self'";
      }
    
    
      location =/ {
          rewrite / /portal/webclient;
      }
   }

4. Download the Horizon HTML Access portal.war zip file from the VMware download page at https://my.vmware.com/web/vmware/downloads.

   Navigate to the download page for your release of VMware Horizon. The filename is VMware-Horizon-View-HTML-Access-YYMM-y.y.y-xxxxxx.zip, where YYMM is the marketing version number, y.y.y is the internal version number and xxxxxx is the build number.

5. Deploy the HTML Access warball.

   #To get portal.war
   unzip VMware-Horizon-View-HTML-Access-YYMM-y.y.y-xxxxxx.zip
    
   cp portal.war /var/lib/tomcat9/webapps
   chmod 755 /var/lib/tomcat9/webapps/portal.war

6. Restart the machine for the changes to take effect.

   sudo chmod -R 750 /var/lib/tomcat/webapps/portal.war

6. Restart the machine for the changes to take effect.

Set Up a RHEL/CentOS 8.x Desktop for HTML Access

1. Download the latest version of Tomcat 9 from https://tomcat.apache.org/.
2. Install the Tomcat software.

   For example:

   sudo useradd -m -U -d /opt/tomcat tomcat
   sudo chmod 755 /opt/tomcat
   wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.43/bin/apache-tomcat-9.0.43.tar.gz

Set Up a SUSE Desktop for HTML Access

1. Install and configure the Tomcat software.

   The following example shows the command sequence for installing Tomcat on a SUSE 15 SP2 machine. In the first command line, replace the example address with the Java download URL for your SUSE version.

   sudo zypper addrepo https://download.opensuse.org/repositories/Java:packages/SLE_15_SP2/Java:packages.repo
   sudo zypper refresh
   sudo zypper install tomcat
    
   #Link tomcat.service to /usr/libexec/tomcat/server
   cd /usr/
   sudo ln -s lib libexec

2. Install the nginx package, if it is not already installed on the SUSE system.
   Note: In the first command line, replace <download URL> as follows:

   • For SLED/SLES 15.x, replace with 'http://nginx.org/packages/sles/15'.
   • For SLED/SLES 12.x, replace with 'http://nginx.org/packages/sles/12'.

   sudo zypper addrepo -G -t yum -c '<download URL>' nginx
   wget http://nginx.org/keys/nginx_signing.key
   sudo rpm --import nginx_signing.key
   sudo zypper install nginx

3. Edit the /etc/nginx/conf.d/vmwvadc.conf configuration file so that it includes the following contents.
