Scroll down to ports , press Space . As with the last section, this section makes an assumption that you have a working Internet connection. If you do not, you will need to perform the CD-ROM installation, or put a copy of the distfile into /usr/ports/distfiles manually. A distinfo file. This file contains information about the files that must be downloaded to build the port and their checksums, to verify that files have not been corrupted during the download using md5 (1) . Note: Once you updated your Ports Collection, before attempting a port upgrade, you should check the /usr/ports/UPDATING file. This file describes various issues and additional steps users may encounter and need to perform when updating a port. The first thing that should be explained when it comes to the Ports Collection is what is actually meant by a ``skeleton''. In a nutshell, a port skeleton is a minimal set of files that tell your FreeBSD system how to cleanly compile and install a program. Each port skeleton includes: Place your FreeBSD CD-ROM in the drive. Mount it on /cdrom . (If you use a different mount point, set CD_MOUNTPTS make variable.) To begin, change to the directory for the port you want to install: Keeping your ports up to date can be a tedious job. For instance, to upgrade a port you would go to the ports directory, build the port, deinstall the old port, install the new port, and then clean up after the build. Imagine doing that for five ports, tedious right? This was a large problem for system administrators to deal with, and now we have utilities which do this for us. For instance the sysutils/portupgrade utility will do everything for you! Just install it like you would any other port, using the make install clean command. To just fetch distfiles (or packages, if -P is specified) without building or installing anything, use -F . For further information see portupgrade (1) . will combine the two (it is too long to completely write on this page, but it should give you the general idea). 4.5.2.4 Dealing with imake. The ports system uses fetch (1) to download the files, which honors various environment variables, including FTP_PASSIVE_MODE , FTP_PROXY , and FTP_PASSWORD . You may need to set one or more of these if you are behind a firewall, or need to use an FTP/HTTP proxy. See fetch (3) for the complete list. Note: It is important to regularly update the package database using pkgdb -F to fix inconsistencies, especially when portupgrade asks you to. Do not abort portupgrade while it is updating the package database, this will leave you an inconsistent database. For questions about FreeBSD, read the documentation before contacting . For questions about this documentation, e-mail . Sometimes it is useful (or mandatory) to use a different distfiles and ports directory. The PORTSDIR and PREFIX variables can override the default directories. For example: 4.5.2 Installing Ports. will compile the port in /usr/home/example/ports and install everything under /usr/local . Using the Ports Collection will use up disk space over time. Because of this tendency of the ports tree to grow in size, after building and installing software from the ports, you should always remember to clean up the temporary work directories using the make clean command. This will remove the work directory after a port has been built and installed. You can also remove the source distribution files from the distfiles directory, and remove the installed ports if the need for them has passed. Before you can install ports, you must first obtain the Ports Collection--which is essentially a set of Makefiles , patches, and description files placed in /usr/ports . As root , run sysinstall ( /stand/sysinstall in FreeBSD versions older than 5.2) as shown below: When installing your FreeBSD system, sysinstall asked if you would like to install the Ports Collection. If you chose no, you can follow these instructions to obtain the ports collection: Some users choose to limit the available port categories by placing an entry in the refuse file. This way, when they run the CVSup application, it will not download the files in that category. More information regarding the refuse file can be found in Section A.5.3.1. If you want to upgrade only a certain application, not the complete database, use portupgrade pkgname , include the flags -r if portupgrade should act on all those packages depending on the given package as well, and -R to act on all packages required by the given packages. The following sections provide basic instructions on using the Ports Collection to install or remove programs from your system. 4.5.2.2 Installing Ports from the Internet. will compile it in /usr/ports and install it in /usr/home/example/local . To use packages instead of ports for installation, prov >-P . With this option portupgrade searches the local directories listed in PKG_PATH , or fetches packages from remote site if it is not found locally. If packages can not be found locally or fetched remotely, portupgrade will use ports. To avo >-PP . Alternatively, these variables can also be set as part of your environment. Read the manual page for your shell for instructions on doing so. Other utilities exist which will do this, check out the ports/sysutils directory and see what you come up with. Scroll down and select Distributions , press Enter . 4.5.2.3 Overriding the Default Ports Directories. Some ports that use imake (a part of the X Window System) do not work well with PREFIX , and will insist on installing under /usr/X11R6 . Similarly, some Perl ports ignore PREFIX and install in the Perl tree. Making these ports respect PREFIX is a difficult or impossible job. Once ins >lsof directory, you will see the port skeleton. The next step is to compile, or ``build'', the port. This is done by simply typing make at the prompt. Once you have done so, you should see something like this: Select your desired installation media, such as CDROM, FTP, and so on. 4.5.4 Ports and Disk Space. In this example we change the MASTER_SITES option to ftp.FreeBSD.org/pub/FreeBSD/ports/distfiles/ . 4.5.5 Upgrading Ports. 4.5.2.1 Installing Ports from a CD-ROM. Running this command later will download and apply all the recent changes to your Ports Collection, except actually rebuilding the ports for your own system. Scroll up to Exit , press Enter . Scroll up to Exit and press Enter . 4.5 Using the Ports Collection. Now that you know how to install ports, you are probably wondering how to remove them, just in case you install one and later on dec >lsof for those of you not paying attention). As with installing ports, the first thing you must do is change to the port directory, /usr/ports/sysutils/lsof . After you change directories, you are ready to uninstall lsof . This is done with the make deinstall command: A security vulnerabilities check can be automatically done by portaudit before any new application installation. This tool can be found in the Ports Collection ( security/portaudit ). Cons >portaudit -F before installing a new port, to fetch the current vulnerabilities database. A security audit and an update of the database will be performed during the daily security system check. For more information read the portaudit (1) and periodic (8) manual pages. This directory may also contain other files used to build the port. A files directory. This directory contains patches to make the program compile and install on your FreeBSD system. Patches are basically small files that specify changes to particular files. They are in plain text format, and basically say ``Remove line 10'' or ``Change line 26 to this . ''. Patches are also known as ``diffs'' because they are generated by the diff (1) program. 4.5.3 Removing Installed Ports. For users which cannot be connected all the time, the make fetch option is prov >/usr/ports ) and the required files will be downloaded for you. This command will also work in the lower level categories, for example: /usr/ports/net . Note that if a port depends on libraries or other ports this will not fetch the distfiles of those ports too. Replace fetch with fetch-recursive if you want to fetch all the dependencies of a port too. Note: 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. If you are using one of these shells, you might have to use the rehash command after installing a port, before the newly installed commands can be used. This command will work for shells like tcsh . Use the hash -r command for shells like sh or shells/bash . Look at documentation for your shell for more information. Change CHANGE_THIS.FreeBSD.org to a CVSup server near you. See CVSup Mirrors (Section A.5.7) for a complete listing of mirror sites. In some rare cases, users may need to acquire the tarballs from a site other than the MASTER_SITES (the location where files are downloaded from). You can overr >MASTER_SITES option with the following command: Scroll down and select Configure , press Enter . A pkg-plist file. This is a list of all the files that will be installed by the port. It also tells the ports system what files to remove upon deinstallation. Note: You can save an extra step by just running make install instead of make and make install as two separate steps. Installing a port from the Internet is done exactly the same way as it would be if you were installing from a CD-ROM. The only difference between the two is that the distfile is downloaded from the Internet instead of read from the CD-ROM. This method involves using sysinstall again to manually install the Ports Collection. Prev Home Next Using the Packages System Up Post-installation Activities. As you can see, the only difference is the line that tells you where the system is fetching the port distfile from. Note: Please be aware that the licenses of a few ports do not allow for inclusion on the CD-ROM. This could be because a registration form needs to be filled out before downloading or redistribution is not allowed, or for another reason. If you wish to install a port not included on the CD-ROM, you will need to be online in order to do so (see the next section). The FreeBSD Project's official CD-ROM images no longer include distfiles. They take up a lot of room that is better used for precompiled packages. CD-ROM products such as the FreeBSD PowerPak do include distfiles, and you can order these sets from a vendor such as the FreeBSD Mall. This section assumes you have such a FreeBSD CD-ROM set. The make deinstall and make reinstall sequence does not work once you have run make clean . If you want to deinstall a port after cleaning, use pkg_delete (1) as discussed in the Packages section of the Handbook. The port includes instructions on how to build source code, but does not include the actual source code. You can get the source code from a CD-ROM or from the Internet. Source code is distributed in whatever manner the software author desires. Frequently this is a tarred and gzipped file, but it might be compressed with some other tool or even uncompressed. The program source code, whatever form it comes in, is called a ``distfile''. The two methods for installing a FreeBSD port are described below. The alternative method to obtain and keep your ports collection up to date is by using CVSup . Look at the ports CVSup file, /usr/share/examples/cvsup/ports-supfile . See Using CVSup (Section A.5) for more information on using CVSup and this file. Press X to exit sysinstall . Note: You can build all the ports in a category or as a whole by running make in the top level directory, just like the aforementioned make fetch method. This is dangerous, however, as some ports cannot co-exist. In other cases, some ports can install two different files with the same filename. Once you are returned to your prompt, you should be able to run the application you just installed. Since lsof is a program that runs with increased privileges, a security warning is shown. During the building and installation of ports, you should take heed of any other warnings that may appear. Note: You must be logged in as root to install ports. A pkg-descr file. This is a more detailed, often multiple-line, description of the program. The steps involved are identical: Warning: Before installing any port, you should be sure to have an up-to-date Ports Collection and you should check http://vuxml.freebsd.org/ for security issues related to your port. Some ports have other files, such as pkg-message . The ports system uses these files to handle special situations. If you want more details on these files, and on ports in general, check out the FreeBSD Porter's Handbook. A Makefile . The Makefile contains various statements that specify how the application should be compiled and where it should be installed on your system. That was easy enough. You have removed lsof from your system. If you would like to reinstall it, you can do so by running make reinstall from the /usr/ports/sysutils/lsof directory. Now create a database with the pkgdb -F command. This will read the list of installed ports and create a database file in the /var/db/pkg directory. Now when you run portupgrade -a , it will read this and the ports INDEX file. Finally, portupgrade will begin to download, build, backup, install, and clean the ports which have been updated. portupgrade comes with a lot of options for different use cases, the most important ones will be presented below. As root , copy /usr/share/examples/cvsup/ports-supfile to a new location, such as /root or your home directory. 4.5.1 Obtaining the Ports Collection. Notice that once the compile is complete you are returned to your prompt. The next step is to install the port. In order to install it, you simply need to tack one word onto the make command, and that word is install : This is a quick method for getting the Ports Collection using CVSup . If you want to keep your ports tree up to date, or learn more about CVSup , read the previously mentioned sections.
