macOS Server not accessible

Issue

  • No port of the server application can be reached.

Diagnose

  • The server system log keeps repeating:

    com.apple.xpc.launchd[1] (com.apple.serviceproxy[10725]): Service exited with abnormal code: 1
com.apple.xpc.launchd[1] (com.apple.serviceproxy): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

  • serviceproxy is the proxy apache service. Having a look at the logs at /var/log/apache2: Nothing conclusive.

  • Trying to start the service manually with the same command that can be seen in the apache logs:

    sudo /usr/sbin/httpd -D FOREGROUND -f /Library/Server/Web/Config/apache2/httpd_server_app.conf

[Sun Sep 10 20:06:31.694672 2017] [core:warn] [pid 10580] AH00111: Config variable ${SERVER_INSTALL_PATH_PREFIX} is not defined
httpd: Syntax error on line 188 of /Library/Server/Web/Config/apache2/httpd_server_app.conf: Cannot load ${SERVER_INSTALL_PATH_PREFIX}/usr/libexec/apache2/mod_bonjour.so into server: dlopen(/usr/${SERVER_INSTALL_PATH_PREFIX}/usr/libexec/apache2/mod_bonjour.so, 10): image not found

 But I guess, this is just because SERVER_INSTALL_PATH_PREFIX is not set within the shell. It should be set through the server environment.

  • Which is the proper launch daemon? I think:

     launchctl load -w /Applications/Server.app/Contents/ServerRoot/System/Library/LaunchDaemons/com.apple.serviceproxy.plist
 launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist

  • I just realise, the proper log is /var/log/apache2/service_proxy_error.log:

How to check which services are listening

It's just netstat -an | grep LISTEN. See: https://stackoverflow.com/q/44961792/2066546

Resolution

Make sure only the server apache is running:

launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
launchctl load -w /Applications/Server.app/Contents/ServerRoot/System/Library/LaunchDaemons/com.apple.serviceproxy.plist
launchctl enable /Applications/Server.app/Contents/ServerRoot/System/Library/LaunchDaemons/com.apple.serviceproxy.plist

Then try to re-initialize the server data as shown in https://gist.github.com/fiedl/3e8e06889029d9544e35c689700629ba and make sure that /Library/Server/Calendar and Contacts/Data is owned by the _calendar user.
