This implementation allows for multiple sqlite 24databases: you can use one for a <a href="virtual.5.html">virtual(5)</a> table, one for an 25<a href="access.5.html">access(5)</a> table, and one for an <a href="aliases.5.html">aliases(5)</a> table if you want. </p> 26 27<h2>Building Postfix with SQLite support</h2> 28 29<p> The Postfix SQLite client utilizes the sqlite3 library, 30which can be obtained from: </p> 31 32<blockquote> 33 <p> <a href="http://www.sqlite.org/">http://www.sqlite.org/</a> </p> 34</blockquote> 35 36<p> In order to build Postfix with sqlite map support, you will 37need to add to CCARGS the flags -DHAS_SQLITE and -I with the directory 38containing the sqlite header files, and you will need to add to 39AUXLIBS the directory and name of the sqlite3 library, plus the 40name of the standard POSIX thread library (pthread). For example: 41</p> 42 43<blockquote> 44<pre> 45make -f Makefile.init makefiles \ 46 'CCARGS=-DHAS_SQLITE -I/usr/local/include' \ 47 '<a href="SQLITE_README.html">AUXLIBS_SQLITE</a>=-L/usr/local/lib -lsqlite3 -lpthread' 48</pre> 49</blockquote> 50 51<p> If your SQLite shared library is in a directory that the RUN-TIME 52linker does not know about, add a "-Wl,-R,/path/to/directory" option after 53"-lsqlite3". </p> 54 55<p> Postfix versions before 3.0 use AUXLIBS instead of <a href="SQLITE_README.html">AUXLIBS_SQLITE</a>. 56With Postfix 3.0 and later, the old AUXLIBS variable still supports 57building a statically-loaded SQLite database client, but only the new 58<a href="SQLITE_README.html">AUXLIBS_SQLITE</a> variable supports building a dynamically-loaded or 59statically-loaded SQLite database client. </p> 60 61<blockquote> 62 63<p> Failure to use the <a href="SQLITE_README.html">AUXLIBS_SQLITE</a> variable will defeat the purpose 64of dynamic database client loading. Every Postfix executable file 65will have SQLITE database library dependencies. And that was exactly 66what dynamic database client loading was meant to avoid. </p> 67 68</blockquote> 69 70<p> Then, just run 'make'.</p> 71 72<h2>Using SQLite tables</h2> 73 74<p> Once Postfix is built with sqlite support, you can specify a 75map type in <a href="postconf.5.html">main.cf</a> like this: </p> 76 77<blockquote> 78<pre> 79<a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="sqlite_table.5.html">sqlite</a>:/etc/postfix/sqlite-aliases.cf 80</pre> 81</blockquote> 82 83<p> The file /etc/postfix/sqlite-aliases.cf specifies lots of 84information telling Postfix how to reference the sqlite database. 85For a complete description, see the <a href="sqlite_table.5.html">sqlite_table(5)</a> manual page. </p> 86 87<h2>Example: local aliases </h2> 88 89<pre> 90# 91# sqlite config file for <a href="local.8.html">local(8)</a> <a href="aliases.5.html">aliases(5)</a> lookups 92# 93 94# Path to database 95dbpath = /some/path/to/sqlite_database 96 97# See <a href="sqlite_table.5.html">sqlite_table(5)</a> for details. 98query = SELECT forw_addr FROM mxaliases WHERE alias='%s' AND status='paid' 99</pre> 100 101<h2>Credits</h2> 102 103<p> SQLite support was added with Postfix version 2.8. </p> 104 105<ul> 106 107<li>Implementation by Axel Steiner</li> 108<li>Documentation by Jesus Garcia Crespo</li> 109 110</ul> 111 112</body> 113 114</html> 115
