To force the use of FTP, change FS_METHOD from direct to ftpext:

From the docs:

FS_METHOD forces the filesystem method. It should only be “direct”, “ssh2”, “ftpext”, or “ftpsockets”. Generally, You should only change this if you are experiencing update problems, If you change it, and it doesnt help change it back/remove it, Under most circumstances, setting it to ‘ftpsockets’ will work if the automatically chosen method does not.

(Primary Preference) “direct” forces it to use Direct File I/O requests from within PHP, this is fraught with opening up security issues on poorly configured hosts, This is chosen automatically when appropriate.
(Secondary Preference) “ssh2” is to force the usage of the SSH PHP Extension if installed
(3rd Preference) “ftpext” is to force the usage of the FTP PHP Extension for FTP Access, and finally
(4th Preference) “ftpsockets” utilises the PHP Sockets Class for FTP Access.

How To Secure Self-Hosted Bamboo and Crucible with Let’s Encrypt SSL Certificates

Author: , Posted on Thursday, September 14th, 2023 at 6:26:30am


In this blog we explore how to use certificates from Let’s Encrypt to secure self-hosted Bamboo and Crucible.

Process To Follow

  • Install Certbot
  • Ensure that external DNS resolves to the correct IP address
  • Ensure that Port 80 is open from the outside to that IP address so that Let’s Encrypt can validate the domain
  • Ensure nothing is listening on Port 80
    netstat -pan | grep 80 | grep LISTEN | wc -l
  • Generate the new certificate via Let’s Encrypt
  • Create the new Java keystore for use with Bamboo and Crucible
  • Copy the new keystore into place and set ownership and permissions
  • Restart the services
  • Test

Install Certbot

You must first install Python >= 3
I like using pip to install certbot, but urge you to use any method that is the easiest and most familiar:
Run certbot help to confirm that it has been installed properly

Generate the Let’s Encrypt Certificate

Create The New Java Keystore

This step will result in two new files being created: example.p12 and example.jks


  • the name/alias MUST be “tomcat” (no quotes)
  • the password MUST be “changeit” (no quotes), unless you modify the config xml settings which is beyond the scope of this blog post.
  • when you list out the new example.jks keystore using keytool, ensure that it says PrivateKeyEntry next to the alias tomcat.
  • ignore the warning at the end because Apache Tomcat requires the JKS keystore format, not the PKCS12 format – do NOT convert!

Copy The Java Keystore Into Place

This step will copy the new keystore (bamboo.jks)into place for both bamboo and Crucible as ~/.keystore for each user. Ownership and permissions must also be set.

Restart Bamboo and Crucible

This step will restart the processes, so they read in the new certificate.

Test Bamboo and Crucible

Use the openssl command to test the new certs:

Locate the current MySQL database certificates, usually in /var/lib/mysql, and make sure that the OS user running sysbench is able to read the following 3 files:

Next, cd to the OS user’s home directory and create symbolic links as follows:

Finally, create a simple wrapper to ensure proper location and adding --mysql-ssl=on to sysbench command, for example:
