Linux RHEL 
I am trying to install SphinxSearch 0.9.8 on Linux RHEL with mySQL. I did the ./configure and everything seemed fine. Then when build the binaries with make, I get the follwing:
sphinx.h:54:19: error: mysql.h: No such file or directory

- I had a similar issue on FC9. I did "yum install mysql-devel" and that fixed it. Try installing the mysql-devel version for your mysql install and then building sphinx. --5 August 2008
- Same here. I'm a debian user. aptitude install libmysql++-dev libmysqlclient15-dev checkinstall corrected the problem. Much Love
init.d script for FC users 
Here is a chkconfig compatible script I created for FC users. It is a modification on a script by Vladimir Fedorkov. This Script assumes you've put the pid file (config in sphinx.conf) in /var/run for selinux purposes. Speaking of selinux, you'll need to add port 3312 to the http port context.
Permission denied and SELinux 
I'm getting this error message when trying to search in MW: Query failed: connection to 127.0.0.1:9312 failed (errno=13, msg=Permission denied).
Deamon is running and responding to search from term.
PHP 5.3.3 (apache2handler)
SphinxSearch (versjon 0.7.0)
Sphinx Engine: Sphinx 0.9.9 (r2117; Dec 02, 2009)
From startup file:
[Thu Aug 5 14:47:37.533 2010] [ 8444] using config file '/etc/sphinx/sphinx.conf'...
[Thu Aug 5 14:47:37.533 2010] [ 8444] listening on 127.0.0.1:9312
Solved: Turn of SELinux. I'm leaving this post if anyone else should run into this problem themselves.
Alternate solution: leave SELinux running, and run this command: setsebool -P httpd_can_network_connect 1 which will allow httpd to make network connections.
Debian and Ubuntu -- api missing 
Debian and Ubuntu now package sphinxsearch; 0.9.9 comes with Sid and Maverick. This of course makes things simpler: no need to download source and build, and the daemon is already configured in sysv.
We still need to copy the sphinx.conf file from this project -- it should be placed in /etc/mediawiki -- along with the rest of the extension. I had to comment out the ports (and add prefixes); then it worked fine.
Upgrades of sphinxsearch within Debian/Ubuntu should work without changing the configuration.
The only problem is the API file, sphinxapi.php. It is not in the binary package. If you download the latest from upstream, you get the dreaded version mismatch error. I haven't tested this in detail, but found that I could use a sphinxapi.php from a sphinxsearch installation from last fall for the 0.9.9.6 version in Ubuntu Maverick. I don't really see an elegant solution -- maybe we should request Debian to package it in the binary deb.
