Traffic Ops - Installing¶
The user must have the following for a successful minimal install:
- CentOS 7
- 2 VMs with at least 2 vCPUs, 4GB RAM, 20 GB disk space each
- Access to Centos Base and epel repositories
- Access to The Comprehensive Perl Archive Network (CPAN)
As of version 2.0 only Postgres is supported as the database. This documentation assumes CentOS 7.2 and Postgresql 9.6.3 for a production install.
Navigating the Install¶
To begin the install:
- Install Postgres
For a production install it is best to install postgres on it’s own server/VM. To install postgres, on the postgres host (pg)pg-$ sudo su - pg-# yum -y update pg-# yum -y install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm pg-# yum -y install postgresql96-server pg-$ su - postgres pg-$ /usr/pgsql-9.6/bin/initdb -A md5 -W #-W forces the user to provide a superuser (postgres) password
/var/lib/pgsql/9.6/data/pg_hba.confto allow your traffic ops app server access. For example if you are going to install traffic ops on
18.104.22.168add:host all all 22.214.171.124/32 md5
to the appropriate section of this file. Edit the
/var/lib/pgsql/9.6/data/postgresql.conffile to add the approriate listen_addresses or
listen_addresses = '*', set
timezone = 'UTC', and start the database:pg-$ exit pg-# systemctl enable postgresql-9.6 pg-# systemctl start postgresql-9.6 pg-# systemctl status postgresql-9.6
Build Traffic Ops
Build a Traffic Ops rpm using the instructions under the Building Traffic Control page.
Install the postgresql 9.6 yum repository access.to-$ sudo su - to-# yum -y install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
Install the rpm built in step 2.
to-# yum -y install ./dist/traffic_ops-2.0.0-xxxx.yyyyyyy.el7.x86_64.rpm
Install some additional packages that it depends on that were not installed as dependecies in the previous step (these are for the 2.0.0 install, this may change, but the pre-installs won’t hurt):to-# yum -y install git to-# wget -q https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz to-# tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz to-# PATH=$PATH:/usr/local/go/bin # go bins are needed in the path for postinstall to-# go get bitbucket.org/liamstask/goose/cmd/goose
At this point you should be able to login to the database from the
tohost to the
pghost like:to-# psql -h 126.96.36.199 -U postgres Password for user postgres: psql (9.6.3) Type "help" for help. postgres=#
Use this connectivity to create the user and database. In this example, we use user:
traffic_ops:to-# psql -U postgres -h 188.8.131.52 -c "CREATE USER traffic_ops WITH ENCRYPTED PASSWORD 'tcr0cks';" Password for user postgres: CREATE ROLE to-# createdb traffic_ops --owner traffic_ops -U postgres -h 184.108.40.206 Password: to-#
Now, run the following command as root:
The postinstall will first get all packages needed from CPAN. This may take a while, expect up to 30 minutes on the first install. If there are any prompts in this phase, please just answer with the defaults (some CPAN installs can prompt for install questions).
When this phase is complete, you will see:Complete! Modules were installed into /opt/traffic_ops/app/local
Some additional files will be installed, and then it will proceed with the next phase of the install, where it will ask you about the local environment for your CDN. Please make sure you remember all your answers and the database answers match the database information previously used to create the database.
