Configure HTTP server: Setup HTTP server as FastCGI proxy

Note

Instructions in this chepter are applied to the HTTP servers accompany with any of these setting methods:

Using Systemd socket

Running separate FastCGI service

They are not applied to servers with earlier (no longer recommended) methods.

If you have not added configuration for Sympa to HTTP server, follow instruction below.

Instruction by HTTP servers

nginx

Add following excerpt to nginx configuration (Note: replace $PIDDIR, $CSSDIR, $PICTURESDIR and $STATICDIR below):
```
server {
    listen      80;
    server_name localhost.localdomain;  # Change it!

    location /sympa {
        include       fastcgi_params;
        fastcgi_param SERVER_NAME $host;  # See note
        fastcgi_pass  unix:$PIDDIR/wwsympa.socket;
    }

    # Section below is needed for 6.2.28 or later.
    location /static-sympa/css {
        alias $CSSDIR;
    }
    # Section below is needed for 6.2.28 or later.
    location /static-sympa/pictures {
        alias $PICTURESDIR;
    }
    location /static-sympa {
        alias $STATICDIR;
    }
}
```
In above, /static-sympa/css, /static-sympa/pictures and /static-sympa are the default values of css_url, pictures_url and statoc_content_url, respectively.

For the SOAP interface, add this in your server configuration (Note: replace $PIDDIR):
```
    location /sympasoap {
        include       fastcgi_params;
        fastcgi_param SERVER_NAME $host;  # See note
        fastcgi_pass  unix:$PIDDIR/sympasoap.socket;
    }
```
See also the notes below.
Note
- Some binary distributions ship configuration ready to edit:
  - On RPM, /etc/nginx/conf.d/sympa.conf file is prepared by sympa-nginx package.
- The line fastcgi_param SERVER_NAME $host; after include line is required if you will manage multiple virtual hosts, i.e. server_name directive has multiple server names.
- With earlier version of Sympa, you may have to add following things:
  - With Sympa 6.2.54 or earlier, insert these into the section of "location /sympa":
```
fastcgi_split_path_info ^(/sympa)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
```
    and these into the section of "location /sympasoap", if any:
```
fastcgi_split_path_info ^(/sympasoap)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
```
  - Additionally, with Sympa 6.2.19b.2 or earlier, insert this into the section of "location /sympa" (Note: replace $EXECCGIDIR).
```
fastcgi_param SCRIPT_FILENAME $EXECCGIDIR/wwsympa.fcgi;
```
Edit it as you prefer.

Note that server_name directive above should contain host part of wwsympa_url parameter. Because Sympa refers to SERVER_NAME CGI environment variable to determine web host name of the service.
Restart nginx. Then test configuration according to instruction.

Apache HTTP Server

Add following excerpt to httpd configuration (Note: replace $PIDDIR, $CSSDIR, $PICTURESDIR and $STATICDIR below):

LoadModule alias_module modules/mod_alias.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

...

<Location /sympa>
    SetHandler "proxy:unix:$PIDDIR/wwsympa.socket|fcgi://localhost"
    # Don't forget to edit lines below!
    Require local
    #Require all granted
</Location>

# Lines below are needed for 6.2.28 or later.
<Location "/static-sympa/css">
    Require all granted
</Location>
Alias /static-sympa/css $CSSDIR

# Lines below are needed for 6.2.28 or later.
<Location "/static-sympa/pictures">
    Require all granted
</Location>
Alias /static-sympa/pictures $PICTURESDIR

<Location /static-sympa>
    Require all granted
</Location>
Alias /static-sympa $STATICDIR

For SOAP interface, add:

<Location /sympasoap>
    SetHandler "proxy:unix:$PIDDIR/sympasoap.socket|fcgi://localhost"
    # Don't forget to edit lines below!
    Require local
    #Require all granted
</Location>

In above, /static-sympa/css, /static-sympa/pictures and /static-sympa are the default values of css_url, pictures_url and statoc_content_url, respectively.

Note
Some binary distributions ship configuration ready to edit:
On Debian (12 "bookworm" or later), /etc/apache2/conf-available/sympa.conf file is prepared. Also, separate /etc/apache2/conf-available/sympa-soap.conf file is prepared for SympaSOAP feature.

Note that you may have to enable proxy_fcgi Apache module by running:
# a2enmod proxy_fcgi
On RPM (RHEL/CentOS 7 or later and Fedora), /etc/httpd/conf.d/sympa.conf file is prepared by sympa-httpd package.

Edit it as you prefer.

Note that ServerName directive above should contain host part of wwsympa_url parameter. Because Sympa refers to SERVER_NAME CGI environment variable to determine web host name of the service.
Restart httpd. Then test configuration according to instruction.

lighttpd

Add following excerpt to lighttpd configuration (Note: replace $PIDDIR, $CSSDIR, $PICTURESDIR and $STATICDIR):

server.modules += ("mod_fastcgi")
server.modules += ("mod_alias")

# Line below is needed for 6.2.28 or later.
alias.url += ( "/static-sympa/css/" => "$CSSDIR/" )
# Line below is needed for 6.2.28 or later.
alias.url += ( "/static-sympa/pictures/" => "$PICTURESDIR/" )
alias.url += ( "/static-sympa/" => "$STATICDIR/" )

$HTTP["url"] =~ "^/sympa" {
fastcgi.server = ( "/sympa" =>
    ((  "check-local" => "disable",
        "socket"      => "$PIDDIR/wwsympa.socket",
    ))
)
}

In above, /static-sympa/css, /static-sympa/pictures and /static-sympa are the default values of css_url, pictures_url and statoc_content_url, respectively.

Edit it as you prefer.
Restart lighttpd. Then test configuration according to instruction.
