Before you go any further, make sure you have Python and that the expected version is available from your command line. You can check this by running:. You should get some output like Python 3. If you do not have Python, please install the latest 3. Due to the way most Linux distributions are handling the Python 3 migration, Linux users using the system Python without creating a virtual environment first should replace the python command in this tutorial with python3 and the python -m pip command with python3 -m pip --user.
Do not run any of the commands in this tutorial with sudo : if you get a permissions error, come back to the section on creating virtual environments, set one up, and then continue with the tutorial as written. If you installed Python from source, with an installer from python.
Securely Download get-pip. Run python get-pip. You can use python get-pip. While pip alone is sufficient to install from pre-built binary archives, up to date copies of the setuptools and wheel projects are useful to ensure you can also install from source archives:.
If you are looking to safely install global command line tools, see Installing stand alone command line tools.
Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications?
Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application. For instance, on a shared host. Makefile : contains statements that specify how the application should be compiled and where its components should be installed.
This directory may also contain other files used to build the port. It also tells the ports system which files to remove upon deinstallation. Some ports include pkg-message or other files to handle special situations. The port does not include the actual source code, also known as a distfile. Before an application can be compiled using a port, the Ports Collection must first be installed.
If it was not installed during the installation of FreeBSD, use one of the following methods to install it:. The key is used to verify the integrity of all downloaded files. Note that Portsnap updates are generated from a snapshot of the main branch of the Ports Collection and cannot be configured to use a different branch for example, quarterly. If it is necessary to use a different branch of the Ports Collection for instance as referenced earlier in conjunction with binary packages , then the Git method must be used.
When using fetch , the extract or the update operation may be run consecutively, like so:. Refer to the Git Primer for a detailed description of Git. Git must be installed before it can be used to check out the ports tree. If a copy of the ports tree is already present, install Git like this:. If the ports tree is not available, or pkg is being used to manage packages, Git can be installed as a package:. This section provides basic instructions on using the Ports Collection to install or remove software.
The detailed description of available make targets and environment variables is available in ports 7. Before compiling any port, be sure to update the Ports Collection as described in the previous section.
Alternately, run pkg audit -F before installing a new port. This command can be configured to automatically perform a security audit and an update of the vulnerability database during the daily security system check.
For more information, refer to pkg-audit 8 and periodic 8. Using the Ports Collection assumes a working Internet connection. It also requires superuser privilege. To compile and install the port, change to the directory of the port to be installed, then type make install at the prompt.
Messages will indicate the progress:. Since lsof is a program that runs with increased privileges, a security warning is displayed as it is installed. Once the installation is complete, the prompt will be returned. Some shells keep a cache of the commands that are available in the directories listed in the PATH environment variable, to speed up lookup operations for the executable file of these commands. Users of the tcsh shell should type rehash so that a newly installed command can be used without specifying its full path.
Use hash -r instead for the sh shell. Refer to the documentation for the shell for more information. During installation, a working subdirectory is created which contains all the temporary files used during compilation. Removing this directory saves disk space and minimizes the chance of problems later when upgrading to the newer version of the port:. Some ports provide build options which can be used to enable or disable application components, provide security options, or allow for other customizations.
If the port depends upon other ports which have configurable options, it may pause several times for user interaction as the default behavior is to prompt the user to select options from a menu. To avoid this and do all of the configuration in one batch, run make config-recursive within the port skeleton. Then, run make install [clean] to compile and install the port.
When using config-recursive , the list of ports to configure are gathered by the all-depends-list target. It is recommended to run make config-recursive until all dependent ports options have been defined, and ports options screens no longer appear, to be certain that all dependency options have been configured. One method is to cd into the directory containing the port and type make config. Another option is to use make showconfig. Another option is to execute make rmconfig which will remove all selected options and allow you to start over.
All of these options, and others, are explained in great detail in ports 7. The ports system uses fetch 1 to download the source files, which supports various environment variables. See fetch 3 for the complete list of supported variables. Note that if a port has any dependencies, running this command in a category or ports skeleton will not fetch the distfiles of ports from another category.
Instead, use make fetch-recursive to also fetch the distfiles for all the dependencies of a port. When using, specify the alternate location:. For example:. These can also be set as environmental variables. Refer to the manual page for your shell for instructions on how to set an environmental variable. Installed ports can be uninstalled using pkg delete. Examples for using this command can be found in the pkg-delete 8 manual page. It is recommended to read the messages as the port is uninstalled.
If the port has any applications that depend upon it, this information will be displayed but the uninstallation will proceed. In such cases, it may be better to reinstall the application in order to prevent broken dependencies. Over time, newer versions of software become available in the Ports Collection. This section describes how to determine which software can be upgraded and how to perform the upgrade. On FreeBSD 10 and later, or if the system has been converted to pkg, the following command will list the installed ports which are out of date:.
For FreeBSD 9. X and lower, the following command will list the installed ports that are out of date:. This file describes various issues and additional steps users may encounter and need to perform when updating a port, including such things as file format changes, changes in locations of configuration files, or any incompatibilities with previous versions. Make note of any instructions which match any of the ports that need upgrading and follow these instructions when performing the upgrade.
The Ports Collection contains several utilities to perform the actual upgrade. Each has its strengths and weaknesses. Historically, most installations used either Portmaster or Portupgrade. Synth is a newer alternative. The choice of which tool is best for a particular system is up to the system administrator. It is recommended practice to back up your data before using any of these tools.
It is designed to use the tools installed with the FreeBSD base system without depending on other ports or databases. To install this utility as a port:. By default, Portmaster makes a backup package before deleting the existing port. If the installation of the new version is successful, Portmaster deletes the backup.
Using -b instructs Portmaster not to automatically delete the backup. Adding -i starts Portmaster in interactive mode, prompting for confirmation before upgrading each port.
Many other options are available. Read through the manual page for portmaster 8 for details regarding their usage. If errors are encountered during the upgrade process, add -f to upgrade and rebuild all ports:. Portmaster can also be used to install new ports on the system, upgrading all dependencies before building and installing the new port.
To use this function, specify the location of the port in the Ports Collection:. View code. For e. Ansible Playbooks Inventory of playbooks and examples used to manage the day to day operational tasks of installing and configuring DataStax Enterprise software suite using package install method.
At end of this exercise, we would have installed the following, DSE 6. Assumptions This playbook was built and tested using a supported version of Ansible v2. In future, if updating Ansible version, thoroughly test the playbooks to ensure there is backward compatiblity. This particular playbook has the following defined roles: os-settings : create users, groups and configure any kernel settings.
