6 dbiproxy - A proxy server for the DBD::Proxy driver
7
9 dbiproxy <options> --localport=<port>
10
12 This tool is just a front end for the DBI::ProxyServer package. All it
13 does is picking options from the command line and calling
14 DBI::ProxyServer::main(). See DBI::ProxyServer for details.
15
16 Available options include:
17
18 --chroot=dir
19 (UNIX only) After doing a bind(), change root directory to the
20 given directory by doing a chroot(). This is useful for security,
21 but it restricts the environment a lot. For example, you need to
22 load DBI drivers in the config file or you have to create hard
23 links to Unix sockets, if your drivers are using them. For example,
24 with MySQL, a config file might contain the following lines:
25
26 my $rootdir = '/var/dbiproxy';
27 my $unixsockdir = '/tmp';
28 my $unixsockfile = 'mysql.sock';
29 foreach $dir ($rootdir, "$rootdir$unixsockdir") {
30 mkdir 0755, $dir;
31 }
32 link("$unixsockdir/$unixsockfile",
33 "$rootdir$unixsockdir/$unixsockfile");
34 require DBD::mysql;
35
36 {
37 'chroot' => $rootdir,
38 ...
39 }
40
41 If you don't know chroot(), think of an FTP server where you can
42 see a certain directory tree only after logging in. See also the
43 --group and --user options.
44
45 --configfile=file
46 Config files are assumed to return a single hash ref that overrides
47 the arguments of the new method. However, command line arguments in
48 turn take precedence over the config file. See the "CONFIGURATION
49 FILE" section in the DBI::ProxyServer documentation for details on
50 the config file.
51
52 --debug
53 Turn debugging mode on. Mainly this asserts that logging messages
54 of level "debug" are created.
55
56 --facility=mode
57 (UNIX only) Facility to use for Sys::Syslog. The default is daemon.
58
59 --group=gid
60 After doing a bind(), change the real and effective GID to the
61 given. This is useful, if you want your server to bind to a
62 privileged port (<1024), but don't want the server to execute as
63 root. See also the --user option.
64
65 GID's can be passed as group names or numeric values.
66
67 --localaddr=ip
68 By default a daemon is listening to any IP number that a machine
69 has. This attribute allows to restrict the server to the given IP
70 number.
71
72 --localport=port
73 This attribute sets the port on which the daemon is listening. It
74 must be given somehow, as there's no default.
75
76 --logfile=file
77 Be default logging messages will be written to the syslog (Unix) or
78 to the event log (Windows NT). On other operating systems you need
79 to specify a log file. The special value "STDERR" forces logging to
80 stderr. See Net::Daemon::Log for details.
81
82 --mode=modename
83 The server can run in three different modes, depending on the
84 environment.
85
86 If you are running Perl 5.005 and did compile it for threads, then
87 the server will create a new thread for each connection. The thread
88 will execute the server's Run() method and then terminate. This
89 mode is the default, you can force it with "--mode=threads".
90
91 If threads are not available, but you have a working fork(), then
92 the server will behave similar by creating a new process for each
93 connection. This mode will be used automatically in the absence of
94 threads or if you use the "--mode=fork" option.
95
96 Finally there's a single-connection mode: If the server has
97 accepted a connection, he will enter the Run() method. No other
98 connections are accepted until the Run() method returns (if the
99 client disconnects). This operation mode is useful if you have
100 neither threads nor fork(), for example on the Macintosh. For
101 debugging purposes you can force this mode with "--mode=single".
102
103 --pidfile=file
104 (UNIX only) If this option is present, a PID file will be created
105 at the given location. Default is to not create a pidfile.
106
107 --user=uid
108 After doing a bind(), change the real and effective UID to the
109 given. This is useful, if you want your server to bind to a
110 privileged port (<1024), but don't want the server to execute as
111 root. See also the --group and the --chroot options.
112
113 UID's can be passed as group names or numeric values.
114
115 --version
116 Supresses startup of the server; instead the version string will be
117 printed and the program exits immediately.
