Current (pre-15), apache httpd requires libmariadb ?

codeguy · 03-29-2018, 07:41 PM

Has this changed? I've never had mysql or mariadb installed and apache works fine. Now I get:

Quote:

httpd: error while loading shared libraries: libmariadb.so.3: cannot open shared object file: No such file or directory

Thoughts?

I think you have two choices.

1. Install mariadb.
2. Try rebuilding httpd without mariadb.

Apache uses apr-util, which was recently recompiled in -current with the --with-mysql option (to enable Apache's mod_dbd module to work with MySQL/MariaDB) - that's probably why you're seeing the new dependency.

and there's this BDFL apr-util comment, maybe related?

codeguy · 03-29-2018, 08:00 PM

In my httpd.conf, I have mod_dbd commented out:
#LoadModule dbd_module lib64/httpd/modules/mod_dbd.so

So its not dynamic?

Is it also going to require lib's for oracle, sql server, sqlite2/3 and odbc?

my current vm is up to date

Code:

ldd /usr/sbin/httpd

shows

Quote:

libsqlite3.so.0 => /usr/lib64/libsqlite3.so.0
libmariadb.so.3 => /usr/lib64/libmariadb.so.3

mariadb-10.2.13-x86_64-1 is part of slackware current install, you didn't install this as orbea suggests?

didn't see the other databases you mentioned

No, I don't like either of orbea's options. Mariadb install size is 180 Meg. What a waste when I'm not going to use it.

Well, curl package require libssh2, parts of xfce4 require gtk3, few other packages require libpulse... you see me complaining about it?
If I fail to meet the requirements for my own personal reasons, then I either recompile or discard the software.

MariaDB is a dependency of apr-util rather than of Apache directly, so not loading mod_dbd doesn't make any difference here:

Code:

$ ldd -v /usr/sbin/httpd
[...]

	/usr/sbin/httpd:

I appreciate this was a flippant comment, but Apache does in fact link against sqlite3:

Code:

$ ldd /usr/sbin/httpd | grep sqlite3
	libsqlite3.so.0 => /usr/lib64/libsqlite3.so.0 (0x00007f7a7cc06000)

You're welcome to maintain your own apr-util package compiled without MySQL support and a httpd package built against that package: that's what I did (vice versa) until I could convince Pat it was worth having --with-mysql as the default.

Only a recompiled apr-util package would be needed. If apr-util doesn't pull in libmariadb.so.3, httpd won't either.

By the way, in Fedora apr-util _does_ pull in not only the MariaDB library, but also PostgreSQL and a couple of other database libraries making those hard dependencies. I expect that it's similar elsewhere. I do not take adding a dependency on something like MariaDB lightly, but in this case it is useful (and it's hardly the only thing in Slackware that depends on that library).

What's the sense of running today the Apache without MySQL or MariaDB, or even PHP?

Quite right - I have no idea why I implied it would, especially given what I'd just typed
