Update 2014-04-09: Using bitcoin-0.9.1 with Heartbleed patch.
You should know that RedHat, CentOS or Amazon Linux AMI are not the best choice when it comes to use Bitcoin wallet or other Bitcoin related activities. If you are looking for the easy path you should use Ubuntu Linux or Microsoft Windows as platform. The community is much bigger there.
But if you are determined like me to have your Bitcoin Wallet in the Cloud here you have some instructions. They apply to RedHat and its branches like AWS Linux AMI and CentOS.
Launch a EC2 Instance using Amazon Linux AMI HVM. In this example is ami-b521dfc2 (Ireland). I suggest to use the HVM version to maintain compatibility among different EC2 Instance Types.
All command are executed using ec2-user
Update & Reboot
sudo yum update sudo reboot |
PU_IAS6 Repository & Berkeley DB4.8
We will need Berkeley DB 4.8 but our OS comes with 4.7. Let's use PUIAS repository to get the RPMs with need.
Create the repository config file /etc/yum.repos.d/puias-computational.repo and paste into it the repository definition.
sudo vim /etc/yum.repos.d/puias-computational.repo |
| [puias-computational] name=PUIAS Computational baseurl=http://puias.math.ias.edu/data/puias/computational/6/x86_64/ enabled=1 gpgcheck=0 |
sudo yum install db48 db48-devel |
Boost-Devel
sudo yum install boost-devel |
OpenSSL
We need Elliptic Curve Encryption for Bitcoin to work. For some reason it is missing in RHEL distributions. We have to patch around that.
Download & Install OpenSSL source
wget https://www.openssl.org/source/openssl-1.0.1f.tar.gz tar xvfz openssl-1.0.1f.tar.gz cd openssl-1.0.1f export CFLAGS="-fPIC" ./config shared |
Disable man pages
vim Makefile |
Locate a line with this content "install: all install_docs install_sw" (Line #543) and remove "install_docs" command from it.
The final result should look like this:
| ... ... ... @$(MAKE) TAR='$(TAR)' TARFLAGS='$(TARFLAGS)' tar dist_pem_h: (cd crypto/pem; $(MAKE) -e $(BUILDENV) pem.h; $(MAKE) clean) install: all install_sw install_sw: @$(PERL) $(TOP)/util/mkdir-p.pl $(INSTALL_PREFIX)$(INSTALLTOP)/bin \ $(INSTALL_PREFIX)$(INSTALLTOP)/$(LIBDIR) \
...
...
... |
Make & Install
make depend make all sudo -E make install |
If we are errors free, continue copying the following files:
sudo cp /usr/local/ssl/lib/pkgconfig/libssl.pc /usr/lib64/pkgconfig/ sudo cp /usr/local/ssl/lib/pkgconfig/libcrypto.pc /usr/lib64/pkgconfig/ sudo cp /usr/local/ssl/lib/libssl.so.1.0.0 /usr/lib64/ sudo cp /usr/local/ssl/lib/libcrypto.so.1.0.0 /usr/lib64/ cd |
Bitcoin
Official Bitcoin download source & Install
cd wget https://bitcoin.org/bin/0.9.1/bitcoin-0.9.1-linux.tar.gz tar xvfz bitcoin-0.9.0-linux.tar.gz cd bitcoin-0.9.0-linux/src/ tar xvfz bitcoin-0.9.0.tar.gz cd bitcoin-0.9.0/ ./configure |
If everything goes well you should have and output like this one:

If it does not, review all the previous steps and repeat.
Make, Install & Execute (Note "d" after bitcoin. We use Bitcoin wallet as daemon)
make sudo make install bitcoind |
Expected output:
| $ bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/ec2-user/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd (you do not need to remember this password) The username and password MUST NOT be the same. If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" admin@foo.com

Bitcoind is telling us that we need a minimal configuration file to start with. With the first execution the .bitcoin folder is automatically created under our user directory.
cd cd .bitcoin vim bitcoin.conf |
You can begin with this basic configuration file (Manual page).
| server=1 daemon=1 rpcuser=<A LONG & UNIQUE USERNAME HERE> rpcpassword=<A VERY GOOD PASSWORD HERE> |
Let's try again:
bitcoind |
And the expected result on console:
| Bitcoin server starting |
and now the debug.log file should be moving. We can see the initialization process and messages like these:

This is our wallet loading and verifying all the Bitcoin blockchain. When the process is complete your wallet will become a node of the Bitcoin network and will help validating Bitcoin transactions. It could take more than 24 hours for the process to complete. You can learn more about this here.
There is a way to speed up this process by downloading a Torrent file. More details at the end of this post.
You can issue commands to interact with the daemon. For instance:
bitcoind getblockcount |
to get the number of blocks imported so far. Type bitcoind help for the whole list.
Initializing Blockchain database using Torrent
bitcoind stop sudo yum install transmission-cli cd ~/.bitcoin transmission-cli https://bitcoin.org/bin/blockchain/bootstrap.dat.torrent bitcoind -loadblock=~/.bitcoin/bootstrap.dat |
