当时是从安装phplib开始的

下载phplib

把phplib中的php目录复制到/var/www/

# cp -r php /var/www/

修改php.ini

auto_prepend_file = prepend.php3#包含的文件

nclude_path = ".:/var/www/php"#指出查找的路径

在测试时会出现：

Fatal error: Call to undefined function pg_connect()

原因：php不支持pgsql。

解决方法，重新编译安装php。

重装php

-------------------------------------

./configure --with-pdo-pgsql --with-pgsql #重点啊

-------------------------------------

make

make install

指定使用的php

#find / -name php

/usr/bin/php

/usr/local/bin/php

#/usr/bin/php -v

5.3.3

#/usr/local/bin/php -v

5.3.6

我下的包是5.3.6，make install 后 ，php  安装在/usr/local/bin/中

通过测试知道 编译后的php能用

设置lighttpd.conf

fastcgi.server中的

"bin-path" => "/usr/bin/php-cgi"

更改为

"bin-path" => "/usr/local/bin/php-cgi"

更换原来的php及 php-cgi

#mv /usr/bin/php /usr/bin/php.bk

#mv /usr/bin/php-cgi /usr/bin/php-cgi.bk

#ln -s /usr/local/bin/php /usr/bin/php

ln -s /usr/local/bin/php-cgi /usr/bin/php-cgi

重启 lighttpd

/etc/init.d/lighttpd restart

测试

-----------------------------------------------------------------------------

数据准备

postgres@~$ /usr/local/pgsql/bin/createdb test

postgres@~$ /usr/local/pgsql/bin/psql test

postgres=# CREATE TABLE Countries (

postgres(#  CountryID char(2) NOT NULL,

postgres(#  CountryName varchar(255) NOT NULL,

postgres(#  PRIMARY KEY  (CountryID)

postgres(# );

CREATE TABLE

postgres=#

postgres=# INSERT INTO Countries VALUES ('AL', 'Albania');

postgres=# INSERT INTO Countries VALUES ('DZ', 'Algeria');

postgres=# INSERT INTO Countries VALUES ('AS', 'American Samoa');

postgres=# INSERT INTO Countries VALUES ('AD', 'Andorra');

postgres=# INSERT INTO Countries VALUES ('AO', 'Angola');

postgres=# INSERT INTO Countries VALUES ('AI', 'Anguilla');

postgres=# INSERT INTO Countries VALUES ('AQ', 'Antarctica');

postgres=# INSERT INTO Countries VALUES ('AG', 'Antigua And Barbuda');

postgres=# INSERT INTO Countries VALUES ('AR', 'Argentina');

postgres=# SELECT * FROM Countries;

countryid |     countryname

-----------+---------------------

AL        | Albania

DZ        | Algeria

AS        | American Samoa

AD        | Andorra

AO        | Angola

AI        | Anguilla

AQ        | Antarctica

AG        | Antigua And Barbuda

AR        | Argentina

(9 rows)

Retrieving data

test.php

-------------------------------------

// attempt a connection

$dbh = pg_connect("host= dbname=test user=postgres");

if (!$dbh) {

die("Error in connection: " . pg_last_error());

}

// execute query

$sql = "SELECT * FROM Countries";

$result = pg_query($dbh, $sql);

if (!$result) {

die("Error in SQL query: " . pg_last_error());

}

// iterate over result set

// print each row

while ($row = pg_fetch_array($result)) {

echo "  $row[0] $row[1]

"  ;

}

// free memory

pg_free_result($result);

// close connection

pg_close($dbh);

?>

总结

php连接考php支持；

如果想使用pgsql，编译的时候使用参数 --with-pgsql；

如果想使用pdo，编译的时候使用参数 --with-pdo-pgsql ；

lighttpd服务器使用php-cgi进行解析，所以要把php-cgi的绝对路径传给fastcgi.server中的"bin-path"
