# Algo pre-install steps for Red Hat/CentOS 6.x (currently 6.8) There is still heavy use of RH/CentOS 6 (which are essentially the basis of Amazon Linux as well) due to stability and lack of systemd. But unfortunately, as a result there are a number of dated libraries, including python 2.6 and limitations. This script will allow end-to-end installation of Algo on a local (or cloud-based) RH/Cent 6 VM to deploy to cloud instances including Digital Ocean and AWS, with zero warnings or errors. ## Step 1: Prep for RH/CentOS 6.8/Amazon ``` yum -y -q update yum -y -q install epel-release ``` Enable any kernel updates: ``reboot`` ## Step 2: Install Ansible & launch Algo Fix GPG key warnings during Ansible rpm install ``rpm --import https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6`` Fix GPG key warning during offical Software Collections (SCL) package install ``rpm --import https://raw.githubusercontent.com/sclorg/centos-release-scl/master/centos-release-scl/RPM-GPG-KEY-CentOS-SIG-SCLo`` RH/Cent 6.x uses Python 2.6 by default, which is explicitly deprecated and produces many warnings and errors, so we will install a safe, non-invasive 2.7 tool set which has to be expressly enabled (and will not survive login sessions and reboots) ``` yum -y -q install centos-release-SCL # install Software Collections Library (to enable Python 2.7) # Won't take effect until explicitly enabled, per login session yum -y -q install python27-python-devel python27-python-setuptools python27-python-pip yum -y -q install openssl-devel libffi-devel automake gcc gcc-c++ kernel-devel wget unzip ansible nano # Enable 2.7 default for this session (needs re-run beween logins & reboots) # shellcheck disable=SC1091 source /opt/rh/python27/enable # We're now defaulted to 2.7 pip -q install --upgrade pip # upgrade pip itself pip -q install pycrypto # python-devel needed to prevent setup.py crash, pycrypto 2.7.1 needed for latest security patch pip -q install setuptools --upgrade wget -q https://github.com/trailofbits/algo/archive/master.zip unzip master.zip cd algo-master || echo "No Algo directory found" # Must be run from algo-master dir: pip -q install -r requirements.txt # install Algo local (pusher) dependencies nano config.cfg ./algo ``` ## Post-install OSX: * Copy ./configs/*mobileconfig to your local Mac * Install the VPN profile on your Mac (10.10+ required) * ``/usr/bin/profiles -I -F ./x.x.x.x_NAME.mobileconfig`` * To remove: ```/usr/bin/profiles -D -F ./x.x.x.x_NAME.mobileconfig``` The VPN connection will now appear under Networks (which can be pinned to the top menu bar if preferred)
