I'm using uberSVN on Ubuntu server. Now, I can't checkout, commit source from Subversion Server ( domain.com:9880, port subversion) I tried to start httpd by command line as: sudo /opt/ubersvn/bin/httpdserverctl start , but I get error: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName httpd (pid 895) already running I tried run this command as follow: cd /opt/ubersvn/bin sudo ./ubersvncontrol start then get errors: Starting SysV Tomcat Using CATALINA_BASE: /opt/ubersvn/tomcat Using CATALINA_HOME: /opt/ubersvn/tomcat Using CATALINA_TMPDIR: /opt/ubersvn/tomcat/temp Using JRE_HOME: /opt/ubersvn/jre Using CLASSPATH: /opt/ubersvn/tomcat/bin/bootstrap.jar Using CATALINA_PID: /opt/ubersvn/data/run/tomcat.pid Existing PID file found during start. Tomcat appears to still be running with PID 943. Start aborted. In the Ubersvn website GUI, I tried start Ubersvn server but get error : How to start Subversion Server ?
