Solution for unable to load database plugin library "libts3db_mysql.so"

[SShaadd]

I don't know if this solution was posted anywhere else but I thought I would lend a hand.

If you have this problem in linux, you will need to access your TS3 directory.
Assuming you have ts3db_mysql.ini or correct startup parameters, this library (libts3db_mysql.so) is linked against an older mysql library. You can verify this by running the command ldd libts3db_mysql.so

#  ldd libts3db_mysql.so
        linux-gate.so.1 =>  (0x008a1000)
        libmysqlclient.so.15 => not found
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00eba000)
        libm.so.6 => /lib/libm.so.6 (0x007ad000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00b83000)
        libc.so.6 => /lib/libc.so.6 (0x00249000)
        /lib/ld-linux.so.2 (0x00229000)

As you can see, "libmysqlclient.so.15 => not found";
libmysqlclient.so is located in most *nix systems in /usr/lib/mysql
You might have something like:

lrwxrwxrwx 1 root root      26 2010-09-07 04:11 libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0
-rwxr-xr-x 1 root root 1533448 2010-07-14 19:36 libmysqlclient_r.so.16.0.0

but if you don't have

lrwxrwxrwx 1 root root      24 2010-09-08 21:06 libmysqlclient.so.15 -> libmysqlclient.so.15.0.0
-rwxr-xr-x 1 root root 1457088 2010-09-08 21:05 libmysqlclient.so.15.0.0

then you will have to find it for your system. You can have both without conflicts, as each program looks for the version of the library it needs. The problem is that with some linux distros the package manager (like YUM) will remove the old library, becase TeamSpeak3 itself is not installed as an RPM, therefore the library dependency is not kept. I recommend the TS3 server come with the approriate libmysqlclient with an install script, if it is going to be linked to it. Otherwise, do the following:

Find an earlier version of mysql-libs. I use fedora, so it was mysql-libs-5.0.67-2.fc10.i386.rpm in the fedora 10 distro at http://mirror.pnl.gov/fedora/linux/r....fc10.i386.rpm - of course it might be in an archive somewhere else by the time you read this. Use wget or download it to a work directory of your choice.
You will need to extract the libmysqlclient.so.15.0.0 out of it. To do this, you need to also have rpm2cpio and cpio both installed on your system.
Then, you will need to move libmysqlclient.so.15.0.0 and make a symbolic link, then reload the library cache.

mkdir mysql-temp
cd mysql-temp
wget http://mirror.pnl.gov/fedora/linux/releases/10/Everything/i386/os/Packages/mysql-libs-5.0.67-2.fc10.i386.rpm
rpm2cpio  mysql-libs-5.0.67-2.fc10.i386.rpm  mysql | cpio -idmv
cp ./usr/lib/mysql/libmysqlclient.so.15.0.0 /usr/lib/mysql
cd ../
rm -rf mysql-temp
cd /usr/lib/mysql
ln -s libmysqlclient.so.15.0.0 libmysqlclient.so.15
ldconfig /usr/lib/mysql

That should do it for you. The alternative might be to downgrade your version of mysql-server, however most admins know the dependency hell that creates sometimes. If you don't understand the example I provided or your service provider doesn't allow shell access, you're out of luck until the TeamSpeak providers link libts3db_mysql.so with (your) version of libmysqlclient

This problem could also be related to other librarys that is not found.
In my case it was libssl and libcrypto that was not found.
Iam running Fedora 13

linux-gate.so.1 => (0x002d0000)
libmysqlclient.so.15 => /usr/lib/mysql/libmysqlclient.so.15 (0x00ca4000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00b44000)
libm.so.6 => /lib/libm.so.6 (0x00110000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00946000)
libc.so.6 => /lib/libc.so.6 (0x0062d000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x003a4000)
libnsl.so.1 => /lib/libnsl.so.1 (0x0088e000)
libssl.so.7 => not found
libcrypto.so.7 => not found
libz.so.1 => /lib/libz.so.1 (0x0013a000)
/lib/ld-linux.so.2 (0x005b5000)
libfreebl3.so => /lib/libfreebl3.so (0x0014d000)
libdl.so.2 => /lib/libdl.so.2 (0x00938000)

LIBCRYPTO was found in /lib and the symbolik link in /usr/lib
and run this command
ln -s /lib/libcrypto.so.1.0.0b /usr/lib/libcrypto.so.7

LIBSSL was found in /usr/lib
and run this command
ln -s /usr/lib/libssl.so.1.0.0b /usr/lib/libssl.so.7

This fixed my unable to load database plugin library "libts3db_mysql.so", halting problem.
