The following PHP extensions are missing: * sockets

[systems0]

Trying to get Cacti going on my CentOS5 box.

Have running
Apache2
PHP5
MySQL5

When I access http://localhost/cacti/ I get the following message on my browser, neither apache nor mysql nor the system report any issues in the logs.

Error

The following PHP extensions are missing:
* sockets
Please install those PHP extensions and retry

Any ideas as to how to correct this problem....

I had to recompile PHP to get it to work. I was jumping from 0.8.6j all the way to 0.8.7d on an old RHEL 4 install in this case, but I had the same problem on a CentOS 5 box. I think PHP had previously been installed from source on the RHEL box; it's something I inherited rather than built myself.

In the ./configure step building PHP, append --enable-sockets to whatever your ./configure command line was before.

I found out what the config used was by creating a file called phpinfo.php in Apache's root directory. The contents of that file consist of:

<?php phpinfo(); ?>

Then go to the URL http://yourserver/phpinfo.php and it should tell you up at the top what the config string was.

That worked!!!
thank you!!!
I had to append --enable-sockets at the beginning of ,.configure and then the rest of my options....

thanks again!

i could not understand what should i do?

php info shows ;

'../configure' '--prefix=/usr' '--datadir=/usr/share/php5' '--mandir=/usr/share/man' '--bindir=/usr/bin' '--with-libdir=lib64' '--includedir=/usr/include' '--sysconfdir=/etc/php5/apache2' '--with-config-file-path=/etc/php5/apache2' '--with-config-file-scan-dir=/etc/php5/conf.d' '--enable-libxml' '--enable-session' '--with-mm' '--with-pcre-regex=/usr' '--enable-xml' '--enable-simplexml' '--enable-spl' '--enable-filter' '--disable-debug' '--enable-inline-optimization' '--disable-rpath' '--disable-static' '--enable-shared' '--program-suffix=5' '--with-pic' '--with-gnu-ld' '--with-system-tzdata=/usr/share/zoneinfo' '--with-apxs2=/usr/sbin/apxs2' '--disable-all' '--disable-cli'

The configure string shows what options were turned on when PHP was compiled. The PHP you're using was built without sockets. You need to recompile PHP, with the same options it had before, and add sockets while you're at it.

I don't know how familiar you are with compiling software, but generally, you download and unpack the source code, configure the options (in your case, it'll be something like "./configure --enable-sockets --prefix=/usr --datadir=/usr/share/php5..." plus everything else in the configure string you posted) , compile it, then install it.

but I still get the error even I compile with --enable-sockets option. I use php -m and I can see the sockets is in.
I restart the http service ,doesn't work. I try add a line extension=sockets.so or extension=/usr/local/xxx/sockets.so
it still doesn't work.

why?

Did you restart httpd, then?
