Bitbucket is a web-based hosting service for projects that use either the Mercurial (since launch) or Git (since October 2011) revision control systems. In this post I’ll show you how to install BitBucket on a FreeBSD server.
NOTE: BitBucket is not supported on FreeBSD, so I wouldn’t recommend this in production.
First, we need some prerequisites:

• FreeBSD 11.x or higher
• OpenJDK 1.8.x or higher
• Git 1.8.x or higher
• Perl 5.8.8 or higher
• bash 4.x or higher
• PostgreSQL 9.6 or higher
• BitBucket 4.13 or higher

Install OpenJDK

Install Java from the packages.

pkg install openjdk8

Add these two lines in /etc/fstab so it mounts the filesystems on boot.

fdesc   /dev/fd         fdescfs         rw      0       0
proc    /proc           procfs          rw      0       0

You can mount them immediately, without a reboot.

mount -t fdescfs fdesc /dev/fd
mount -t procfs proc /proc

Make sure you have the correct version.

java -version
openjdk version "1.8.0_112"
OpenJDK Runtime Environment (build 1.8.0_112-b16)
OpenJDK 64-Bit Server VM (build 25.112-b16, mixed mode)

Install Git and Perl

On a fresh FreeBSD install, Perl doesn’t come up pre-installed as before, so we have to install it from the ports. Perl is a prerequisite for Git, so once you install Git, you will install Perl as well.

pkg install git

Check the versions.

git --version
git version 2.11.0
perl --version
This is perl 5, version 24, subversion 1 (v5.24.1) built for amd64-freebsd-thread-multi

Install bash

We also need bash, some of the BitBucket startup scripts use bash.

pkg install bash

Add this line to /etc/fstab.

fdesc   /dev/fd         fdescfs         rw      0       0

You can mount the filesystem immediately.

mount -t fdescfs fdesc /dev/fd

Create a symlink for programs that expect bash under /bin/bash.

cd /bin
ln -s /usr/local/bin/bash

Install PostgreSQL

BitBucket comes with its own database, but it’s for testing only. In addition, on their web-site, Atlassian suggests not to use MySQL or MariaDB because of some performance issues with large instances. So, we’ll use PostgreSQL and we don’t have to worry about any JDBC connectors.

pkg install postgresql96-server

This will install the PostgreSQL client as well. Add this line so PostgreSQL starts at boot.

echo 'postgresql_enable="YES"' >> /etc/rc.conf

Initialize the database for the first time.

/usr/local/etc/rc.d/postgresql initdb

Check this file – /var/db/postgres/data96/postgresql.conf.
By default PostgreSQL listens on the localhost interface which is fine for us, because we’ll use the same server for BitBucket and PostgreSQL. So, leave this line as is.

#listen_addresses = 'localhost'

If you have a separate server for PostgreSQL, make sure that listen_address is set to listen_address=”*”.
Also, check the pg_hba.conf file in the same directory.
This line is fine.

host    all             all             127.0.0.1/32            trust

If you run PostgreSQL and BitBucket on different boxes, you’ll have to modify accordingly. The file has plenty of examples.
Now, let’s start PostgreSQL.

/usr/local/etc/rc.d/postgresql start

Switch to the postgres user that runs PostgreSQL.

su postgres

Create a super-root-admin-dba-sa user.

createuser -sdrP dba
Enter password for new role:
Enter it again:

Start the PostgreSQL shell.

psql

Create a BitBucket user and a database. Modify accordingly.

CREATE ROLE bitbucketuser WITH LOGIN PASSWORD 'jellyfish' VALID UNTIL 'infinity';
CREATE DATABASE bitbucket WITH ENCODING='UTF8' OWNER=bitbucketuser CONNECTION LIMIT=-1;

Hit CTRL-D or type \q to exit.

Add a BitBucket user

We don’t want BitBucket to run as root, so we’ll create a separate user for that. Use the defaults for the other prompts.

adduser
Username: bitbucket
Full Name: Atlassian bitbucket
Shell: bash
Enter password:
Re-enter password: 
OK? Yes
Add another user? no

Install BitBucket

We can’t fetch or wget BitBucket tarball from a command prompt so we’ll have to download it somehow from a GUI. In my case I’ll put the tarball under /tmp.

Then, I’ll extract it to /usr/local/ and I’ll get a folder called atlassian-bitbucket-4.13.0, which is too long, so I’ll just rename it to bitbucket.

cd /tmp
tar xzvf atlassian-bitbucket-4.13.0.tar.gz -C /usr/local
cd /usr/local
mv atlassian-bitbucket-4.13.0/ bitbucket

Final setup

BitBucket will run as the bitbucket user, so that user will need to own the installation directory.

cd /usr/local
chown -R bitbucket:bitbucket bitbucket

BitBucket also requires a home directory. This is different than the home directory for the bitbucket user. We’ll create the home directory under /usr/local/etc.

cd /usr/local/etc
mkdir bitbucket
chown -R bitbucket:bitbucket bitbucket

Now log as the bitbucket user.

su - bitbucket

Edit the .profile file, uncomment the PATH directive and add the BITBUCKET_HOME variable so it looks like this.

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:$HOME/bin:/usr/local/linux-oracle-jre1.8.0/bin; export PATH
BITBUCKET_HOME=/usr/local/etc/bitbucket; export BITBUCKET_HOME

Hit CTRL-D to exit the bitbucket session and then log back as bitbucket.

su - bitbucket

Starting BitBucket

Go to the install dicrectory.

cd /usr/local/bitbucket/bin

You can start BitBucket with the bundled ElasticSearch or not.
With ElasticSearch.

./start-bitbucket.sh

Without ElasticSearch.

./start-webapp.sh

If you see something like this, you are all set.

Using CLASSPATH:       /usr/local/bitbucket/bin/bitbucket-bootstrap.jar:/usr/local/bitbucket/bin/bootstrap.jar:/usr/local/bitbucket/bin/tomcat-juli.jar
Using CATALINA_PID:    /usr/local/bitbucket/work/catalina.pid
Tomcat started.

Success! You can now use Bitbucket at the following address:

http://localhost:7990/

If you cannot access Bitbucket at the above location within 3 minutes, or encounter any other issues starting or stopping Atlassian Bitbucket, please see the troubleshooting guide at:

Go to http://your_IP_hostname_whatever:7990
…and you are on your own.
