Sockets

[bemartinezm]

Hi!
I have just updated cacti from 0.8.7b to 0.8.7e vesion, and when i try to access cacti (http://localost), it appears this message:


"The following PHP extensions are missing:

sockets
Please install those PHP extensions and retry"

Which can be the problem?

Thanks!

The problem is, that cacti can't open a network socket. To do so, we need php-socket support. Many distros have it built-in, but some don't. Unfortunately, the name of a required additional php module differs from distro to distro.

From particular version of Cacti (I'm not sure), it seems that php-socket support is needed to work downed-device detection via SNMP.

Try to perform ./configure with "--enable-sockets" option, then re-build PHP.

To check:
% php -m | grep sockets

I have the same problem, despite sockets module present.

To check more detailed:

Code: Select all

% php -i | grep -i socket
...
Registered Stream Socket Transports => tcp, udp, unix, udg
MYSQL_SOCKET => /tmp/mysql.sock
mysql.default_socket => no value => no value
sockets
Sockets Support => enabled
default_socket_timeout => 60 => 60

Or, please make sure whether you don't have multiple installation of PHP.

Or, try this:

(See "Troubleshooting" section)

Or, ... (no idea, sorry)

So, in more recent PHP's, you have the option of having a separate configuration for both Apache and the CLI. More than likely you have an Apache configuration that removes Socket support and a CLI configuration that enables it. Check under '/etc/php5' for more information.

But where must I put "--enable-sockets"? In which File?

[TheWitness]

there should be a conf.d directory. look for it.
