二、测试busybox httpd：
1. cat /www/index.html
<h1>Welcome to Tinyfs</h1>
<p>zengjf</p>
2. shell命令：/usr/sbin/httpd -vv -f -h /www/
3. 查看ARM板IP：
[zengjf@root www]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 1E:ED:19:27:1A:B3
inet addr:10.0.1.52 Bcast:10.0.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:39 errors:0 dropped:0 overruns:0 frame:0
TX packets:33 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:4990 (4.8 KiB) TX bytes:4050 (3.9 KiB)
[zengjf@root www]#
4. PC机浏览器访问：http://10.0.1.52/
经验证获取到了正确信息，Vim里贴不上图，就不贴图了。
5. shell响应如下：
[zengjf@root www]# /usr/sbin/httpd -vv -f -h /www/
10.0.1.50:55185: url:/
10.0.1.50:55185: response:200
三、编译、安装、测试php-5.5.31
1. ./configure -host=arm-linux-gnueabihf -prefix=/usr/local/php -disable-all -enable-pdo -with-sqlite3 -with-sqlite -with-pdo-sqlite -with-zlib -without-iconv
2. make
1. 错误
ext/sqlite3/libsqlite/sqlite3.o: In function `unixDlError':
/home/Qt/rootfs/busybox/php/php-5.5.31/ext/sqlite3/libsqlite/sqlite3.c:31521: undefined reference to `dlerror'
ext/sqlite3/libsqlite/sqlite3.o: In function `unixDlClose':
/home/Qt/rootfs/busybox/php/php-5.5.31/ext/sqlite3/libsqlite/sqlite3.c:31552: undefined reference to `dlclose'
ext/sqlite3/libsqlite/sqlite3.o: In function `unixDlSym':
/home/Qt/rootfs/busybox/php/php-5.5.31/ext/sqlite3/libsqlite/sqlite3.c:31548: undefined reference to `dlsym'
ext/sqlite3/libsqlite/sqlite3.o: In function `unixDlOpen':
/home/Qt/rootfs/busybox/php/php-5.5.31/ext/sqlite3/libsqlite/sqlite3.c:31507: undefined reference to `dlopen'
collect2: error: ld returned 1 exit status
make: *** [sapi/cli/php] Error 1
2. 解决方法：
修改Makefile中的：
EXTRA_LIBS = -lcrypt -lcrypt -lrt -lz -lm -lcrypt -lcrypt
为：
EXTRA_LIBS = -lcrypt -lcrypt -lrt -lz -lm -lcrypt -lcrypt -ldl
3. 效果：
end_closures.lo Zend/zend_float.lo Zend/zend_string.lo Zend/zend_signal.lo Zend/zend_generators.lo Zend/zend_objects.lo Zend/zend_object_handlers.lo Zend/zend_objects_API.lo Zend/zend_default_classes.lo Zend/zend_execute.lo main/internal_functions_cli.lo sapi/cgi/cgi_main.lo sapi/cgi/fastcgi.lo -lcrypt -lcrypt -lrt -lz -lm -lcrypt -lcrypt -ldl -o sapi/cgi/php-cgi
Build complete.
Don't forget to run 'make test'.
3. sudo make install
4. 拷贝PC机/usr/local/php目录下文件到：<filesystem root>/usr/local/php
5. 配置httpd.conf:
cat /etc/httpd.conf
*.php:/usr/local/php/bin/php-cgi
6. cat /www/test.php
<?
phpinfo();
?>
7. PC机浏览器访问：http://10.0.1.52/test.php
1. 报错现象：
This PHP CGI binary was compiled with force-cgi-redirect enabled. This means that a page will only be served up if the REDIRECT_STATUS CGI variable is set, e.g. via an Apache Action directive.
For more information as to why this behaviour exists, see the manual page for CGI security.
For more information about changing this behaviour or re-enabling this webserver, consult the installation file that came with this distribution, or visit the manual page.
2. 解决办法：
将force-cgi-redirect设置disable。
8. 查看php.ini位置：
[zengjf@root /usr/local/php/bin]# ./php-cgi -i | grep ini
<tr><td class="e">Configuration File (php.ini) Path </td><td class="v">/usr/local/php/lib </td></tr>
<tr><td class="e">Loaded Configuration File </td><td class="v">/usr/local/php/lib/php.ini </td></tr>
<tr><td class="e">Scan this dir for additional .ini files </td><td class="v">(none) </td></tr>
<tr><td class="e">Additional .ini files parsed </td><td class="v">(none) </td></tr>
<tr><td class="e">user_ini.cache_ttl</td><td class="v">300</td><td class="v">300</td></tr>
<tr><td class="e">user_ini.filename</td><td class="v">.user.ini</td><td class="v">.user.ini</td></tr>
<tr><td class="e">Classes </td><td class="v">AppendIterator, ArrayIterator, ArrayObject, BadFunctionCallException, BadMethodCallException, CachingIterator, CallbackFilterIterator, DirectoryIterator, DomainException, EmptyIterator, FilesystemIterator, FilterIterator, GlobIterator, InfiniteIterator, InvalidArgumentException, IteratorIterator, LengthException, LimitIterator, LogicException, MultipleIterator, NoRewindIterator, OutOfBoundsException, OutOfRangeException, OverflowException, ParentIterator, RangeException, RecursiveArrayIterator, RecursiveCachingIterator, RecursiveCallbackFilterIterator, RecursiveDirectoryIterator, RecursiveFilterIterator, RecursiveIteratorIterator, RecursiveRegexIterator, RecursiveTreeIterator, RegexIterator, RuntimeException, SplDoublyLinkedList, SplFileInfo, SplFileObject, SplFixedArray, SplHeap, SplMinHeap, SplMaxHeap, SplObjectStorage, SplPriorityQueue, SplQueue, SplStack, SplTempFileObject, UnderflowException, UnexpectedValueException </td></tr>
9. 配置php.ini：
cat /usr/local/php/lib/php.ini
cgi.force_redirect = 0
cgi.redirect_status_env ="yes";
10. PC机浏览器访问：http://10.0.1.52/test.php
经验证获取到了正确信息，Vim里贴不上图，就不贴图了。
11. shell响应如下：
[zengjf@root /usr/local/php/lib]# /usr/sbin/httpd -vv -f -h /www/
10.0.1.50:58652: url:/
10.0.1.50:58652: response:200
10.0.1.50:58656: url:/test.php
四、编译、安装、测试sqlite3：
1. ./configure --host=arm-linux-gnueabihf --prefix=/usr/local/sqlite
2. make
3. sudo make install
1. 报错：
libtool: install: /usr/bin/install -c .libs/libsqlite3.a /usr/local/sqlite/lib/libsqlite3.a
libtool: install: chmod 644 /usr/local/sqlite/lib/libsqlite3.a
libtool: install: arm-linux-gnueabihf-ranlib /usr/local/sqlite/lib/libsqlite3.a
./libtool: line 1720: arm-linux-gnueabihf-ranlib: command not found
make[1]: *** [install-libLTLIBRARIES] Error 127
make[1]: Leaving directory `/home/Qt/rootfs/busybox/sqlite/sqlite-autoconf-3100200'
make: *** [install-am] Error 2
2. 解决方法：
是由于使用了sudo，导致环境变丢失，用su切换到root用户，再重新设置环境变量来解决。
4. 拷贝/usr/local/sqlite中的文件到<filesystem root>下对应的目录。
5. 建立软链接：ln -s /bin/sqlite3 /bin/sqlite
6. 不能使用退格键（backspace）：
1. 错误现象：
[zengjf@root ~]# sqlite
SQLite version 3.10.2 2016-01-20 15:27:19
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.
sqlite> shw^H^H^H^H^H
2. 解决方法：
终端执行shell命令：stty erase ^H
7. 在ARM板上运行效果如下：
[zengjf@root ~]# sqlite
SQLite version 3.10.2 2016-01-20 15:27:19
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.
sqlite> .show
echo: off
eqp: off
explain: off
headers: off
mode: list
nullvalue: ""
output: stdout
colseparator: "|"
rowseparator: "\n"
stats: off
width:
sqlite> .quit
[zengjf@root ~]#
8. cat /www/teatdb.php
<?
$db = new SQLite3('my_database') or die('Unable to open database');
$query = <<<EOD
CREATE TABLE IF NOT EXISTS users (
username STRING PRIMARY KEY,
password STRING)
EOD; # 这里一定要顶格
$db->exec($query) or die('Create db failed');
$query = <<<EOD
INSERT INTO users VALUES ( 'zengjf', 'root' )
EOD; # 这里一定要顶格
$db->exec($query) or die("Unable to add user $user");
$result = $db->query('SELECT * FROM users') or die('Query failed');
while ($row = $result->fetchArray())
{
echo "User: {$row['username']}\nPasswd: {$row['password']}\n";
}
?>
9. PC机浏览器访问：http://10.0.1.52/testdb.php
经验证获取到了正确信息，Vim里贴不上图，就不贴图了。
10. shell响应如下：
[zengjf@root ~]#
127.0.0.1:54905: url:/
127.0.0.1:54905: response:200
10.0.1.50:51536: url:/testdb.php
11. 可能错误:
1. Fatal error: Class 'SQLiteDatabase' not found in /www/testdb.php on line 3
2. 这是由于移植的sqlite3，可能这里使用的是sqlite的接口，
使用sqlite3的接口可以避免这个错误。
