I am trying to install cakephp ( a php framework) which requires to enable mod_rewrite. For this I followed Enable mod_rewrite answer. But after restarting my server It says:
nitish@nitish-G31T-M7:~$ service apache2 restart Restarting web server apache2 /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted) apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted) apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs **Action 'start' failed.** The Apache error log may have more information. What this means? How can I enable mod_rewrite ?
