I have tried downloading TOR by following this article but I am getting 503 errors. So is there no other way to download TOR? Please can someone help me as I have to do a research project on it.
I am using a centOS server: CentOS Linux release 7.3.1611 (Core) but am getting the follwing errors,
[sam@xx etc]$ sudo yum install tor

Tor no longer recommends using their repo for CentoOS and to instead use epel repos. You'll just end up with a very old version out of their repos.
Instead do:
yum install epel-release
yum install tor
This will get you a current version of Tor managed by a repo. This is perfectly fine.
For CentOS, I have been self-compiling for a while. I have a hacky shell script I'm not yet willing to post here ;) but really it's just compiling Tor and OpenSSL. I'd still recommend using the epel-release since its more tested.
To try building it yourself, grab a recent copy of OpenSSL (eg 1.1.0x), then grab the version of Tor you want to build (eg 0.2.9.8). Make sure libevent is installed ( yum install libevent-devel libevent
).
From OpenSSL source dir:
./config no-shared zlib-dynamic --prefix=/opt/openssl \
--openssldir=/opt/openssl -fPIC enable-ec_nistp_64_gcc_128
make
make test
make install
OpenSSL 1.1.1 note: Remove the no-shared
option when building OpenSSL, otherwise Tor configuration will fail with an error that it can't find a linkable OpenSSL even though it is being built statically. Tor will still link a static OpenSSL but it seems to require the shared libraries to work.
This installs OpenSSL to /opt/openssl
so it doesn't interfere or replace the system's OpenSSL.
Then, build Tor:
./configure --prefix=/opt/tor-VERSION --sysconfdir=/etc \
--localstatedir=/var --enable-static-openssl \
--with-openssl-dir=/opt/openssl --with-tor-user=tor --with-tor-group=tor
make
make test
make install
unlink /usr/bin/tor && ln -s /opt/tor-VERSION/bin/tor /usr/bin/tor
