v5 v6 1 1 = Setting up a BOINC server = 2 2 3 You can potentially use any Unix system as a BOINC server. Our recommendations are: 3 == Using a virtual machine == 4 4 5 * '''Hardware''': use a host with good CPU capacity (dual Xeon or Opteron), at least 2 GB of RAM, and at least 40 GB of free disk space. Do whatever you can to make it highly reliable (UPS power supply, RAID disk configuration, hot-swappable spares, tempurature-controlled machine room, etc.). If you anticipate a high-traffic project, use a machine whose RAM capacity is 8 GB or more and that uses 64-bit processors. If your server capacity is exceeded, you can increase capacity using [MultiHost multiple server hosts]. However, we recommend that you not do this initially. In most cases one host is enough. 6 * '''Software''': use a recent Linux release. 5 The easiest (and recommended) way to set up a BOINC server is 6 in a virtual machine that we've created for that purpose, 7 with all the necessary software already installed. 7 8 8 == Groups and permissions == 9 == Using a real machine == 10 11 You can potentially use any Unix system as a BOINC server. 12 We recommend using a recent Linux release. 13 Then set up the machine as follows. 14 15 === Groups and permissions === 9 16 BOINC server programs run as two different users: 10 17 * The scheduler and file upload handler are CGI programs, so they run as the same user as the web server (typically user 'apache', group 'apache'). … … 13 20 By default, the directories created by user apache are not world-writeable. This causes problems: for example, when the file upload handler creates a directory in the [DirHierarchy upload hierarchy], it's owned by (apache, apache), and the [http://boinc.berkeley.edu/trac/wiki/FileDeleter file deleter] (which runs as boincadm) won't be able to delete the files there. 14 21 15 == Recommended solution == 16 17 Edit /etc/group so that apache belongs to group boinc, i.e. the line: 22 To solve this problem, edit /etc/group so that apache belongs to group boinc, i.e. the line: 18 23 19 24 {{{ … … 28 33 When you create a BOINC project using [MakeProject make_project], the critical directories are owned by boincadm and have the set-GID bit set; this means that any directories or files created by apache in those directories will have group boinc (not group apache). The BOINC software makes all directories group read/write. Thus, both apache and boinc will have read/write access to all directories and files, but other users will have no access. 29 34 30 On an existing project, do:35 To fix permissions on an existing project, do: 31 36 32 37 {{{ … … 42 47 43 48 44 == Installing BOINC software==49 === Installing BOINC software === 45 50 * Download and install whatever [SoftwarePrereqsUnix software prerequisites] are needed on your system. 46 51 * [SourceCode Download the BOINC software]. 47 52 * [BuildSystem Configure and build] the BOINC software. 48 53 49 == Operating system configuration==54 === Operating system configuration === 50 55 Some parts of the BOINC server (the feeder and scheduling server) use shared memory. Hosts where these run must have shared memory enabled, with a maximum segment size of at least 32 MB. How to do this depends on the operating system; some information is [http://developer.postgresql.org/docs/postgres/kernel-resources.html here]. 51 56 52 == MySQL notes==57 === MySQL notes === 53 58 * After installing and running the server, grant permissions for your own account and for the account under which Apache runs ('nobody' in the following; may be different on your machine). All mysql accounts should be password protected including root. 54 59 {{{ … … 69 74 * Set your LD_LIBRARY_PATH to refer to the correct library. 70 75 71 == Apache notes==76 === Apache notes === 72 77 In httpd.conf, set the default MIME type as follows (otherwise you'll get file upload signature verification errors): 73 78 … … 79 84 To limit denial-of-service attacks, we recommend turning off directory indexing by adding -Indexes to the Options directive. 80 85 81 == PHP notes==86 === PHP notes === 82 87 83 88 * Make sure 'magic quotes' are enabled (this is the default). The file /etc/php.ini should contain
