   8 1. Introduction
   9
  10 The suPHP Apache module together with suPHP itself provides an easy way to
  11 run PHP scripts with different users on the same server.
  12
  13 It provides security, because the PHP scripts are not run with the rights of
  14 the webserver's user.
  15 In addition to that you probably won't have to use PHP's "safe mode", which
  16 applies many restrictions on the scripts.
  17
  18 Please note that the suPHP binary has to be installed setuid-root to work,
  19 so a security bug in suPHP probably will allow atackers to run commands with
  20 root privileges. Although I currently don't know any bug in suPHP I can't
  21 guarantee that there aren't any.
  22
  23 2. Installation
  24
  25 Run ./configure with the appropriate paramters for your system.
  26
  27 On most systems a
  28  ./configure --prefix=/usr
  29 will suffice.
  30
  31 The configure script can take the familar GNU autoconf arguments plus the
  32 following suPHP specific ones:
  33
  34 --disable-checkpath: With this compile time option suPHP does not check,
  35                      whether a script (or a symink to it)is inside the
  36                      DOCUMENT_ROOT. You may want to activate this option
  37                      if you are working with "Alias"-directives.
  38
  39 --disable-checkuid:  You may specify this option to make suPHP work with
  40                      scripts whose UIDs are not listed in /etc/passwd.
  41
  42 --disable-checkgid:  You may specify this option to make suPHP work with
  43                      scripts whose GIDs are not listed in /etc/group.
  44
  45 --with-apxs=FILE:    Path to "apxs" of your Apache installation. If not
  46                      specified, configure will look for apxs in your PATH.
  47                      Without apxs the Apache module mod_suphp will not be
  48                      built. It will not be built either, if your Apache has
  49                      been compiled without DSO support. Please make sure you
  50                      specify the right path to apxs, because suPHP will use
  51                      apxs to check whether to build mod_suphp for Apache 1
  52                      or Apache 2.
  53
  54 --with-min-uid=UID:  The minium UID that suPHP will allow PHP to run scripts
  55                      with (defaults to 100).
  56
  57 --with-min-gid=GID:  The minium GID that suPHP will allow PHP to run scripts
  58                      with (defaults to 100).
  59
  60 --with-apache-user=USERNAME:
  61                      Username (not UID) Apache is running as (defaults to
  62                      wwwrun).
  63
  64 --with-logfile=FILE  Path to the suPHP logfile (defaults to
  65                      /var/log/httpd/suphp_log).
  66
  67 --with-setid-mode=MODE:
  68                      MODE has to be one of:
  69                      "owner":    Run scripts with owner UID/GID
  70                      "force":    Run scripts with UID/GID specified in Apache
  71                                  configuration
  72                      "paranoid": Run scripts with owner UID/GID but also check
  73                                  if they match the UID/GID specified in the
  74                                  Apache configuration
  75                      The default is "paranoid" mode.
  76                      You should *NEVER* use "force" mode as it is very
  77                      dangerous.
  78                      While "owner" mode is not as dangerous as "force" mode
  79                      its use is disadvised and "paranoid" mode should be
  80                      preferred.
  81
  82 Now compile suPHP using "make" and if no error occured install it using
  83 "make install". Be sure to be root, when you try to install it.
  84
  85 If your Apache is running with DSO support and "apxs" was found during the
  86 build process, you are done. Otherwise you have to rebuilt your Apache
  87 server with "mod_suphp.c" included. If you used another prefix during the
  88 suPHP build than "/usr", you have to modify "mod_suphp.c" to set the path to
  89 the suPHP executable (which you can find in $exec_prefix/sbin/suphp).
  90
  91 Details on how to compile your Apache webserver with mod_suphp can be found
  92 in apache/INSTALL.
  93
  94 Now, you have to modify your "httpd.conf" to activate suPHP for specific
  95 VHosts. See apache/CONFIG for details on this.
  96
  97 Please note that in order to make suPHP work, you have to specify at least
  98 one handler in the suPHP configuration file. Read CONFIG for additonal
  99 information about how to configure suPHP.
