Configure the Apache HTTP Server

1. Create a virtual host file for the Codar nodes. In the <codar_home>\Apache2.2\conf\extra directory (for Microsoft Windows) or the /etc/httpd/conf.d directory (for Linux), create a file named csa.conf that contains the following content:

   Listen 8443
   <VirtualHost _default_:8443>
   ServerName [APACHE_LOAD_BALANCER_HOSTNAME]
   ErrorLog /etc/httpd/logs/csa_error.log
   TransferLog /etc/httpd/logs/csa_access.log
   SSLEngine on
   SSLProtocol all TLSv1
   SSLCertificateFile /etc/httpd/conf/apache_csa.crt
   SSLCertificateKeyFile /etc/httpd/conf/apache_csa.key
   <Proxy *>
   Order deny,allow
   Allow from all
   </Proxy>
   RewriteEngine On
   RewriteCond %{THE_REQUEST} \ (.*)//+(.*)\ [NC]
   RewriteRule .* %1/%2 [R=301,L]
   Header add Set-Cookie "CSA_ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/"
   env=BALANCER_ROUTE_CHANGED
   <Proxy balancer://csacluster/>
   BalancerMember http://[CSA_NODE1_HOSTNAME]:8081 route=csa1
   BalancerMember http://[CSA_NODE2_HOSTNAME]:8081 route=csa2
   BalancerMember http://[CSA_NODE3_HOSTNAME]:8081 route=csa3
   ProxySet stickysession=CSA_ROUTEID
   </Proxy>
   ProxyPass / balancer://csacluster/
   ProxyPassReverse / balancer://csacluster/
   </VirtualHost>

2. Edit the <codar_home>\Apache2.2\conf\httpd.conf (for Microsoft Windows) /etc/httpd/conf/httpd.conf file (for Linux systems):

   1. Add or update the list of modules that are loaded to include the following modules:

      Microsoft Windows

      Linux

      LoadModule authz_host_module modules\mod_authz_host.so LoadModule headers_module modules\mod_headers.so LoadModule log_config_module modules\mod_log_config.so LoadModule proxy_module modules\mod_proxy.so LoadModule proxy_balancer_module modules\mod_proxy_balancer.so LoadModule proxy_connect_module modules\mod_proxy_connect.so LoadModule proxy_http_module modules\mod_proxy_http.so LoadModule rewrite_module modules\mod_rewrite.so LoadModule ssl_module modules\mod_ssl.so

      LoadModule authz_host_module modules/mod_authz_host.so LoadModule headers_module modules/mod_headers.so LoadModule log_config_module modules/mod_log_config.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_balancer_module modules/mod_proxy_balancer.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule ssl_module modules/mod_ssl.so

   2. Add the following line:

      For Microsoft Windows:

      Include conf\extra\csa.conf

      For Linux:

      Include conf.d/*.conf
