Không thể kết nối php đến mysql khi install Lighttpd in chroot !

EM đã tiến hành cài đăt lighttpd vào trong chroot như sau

Code:

/configure --prefix=/webroot --disable-ipv6 --enable-sendfile64 --with-linux-aio --with-pcre-regex && make && make install

Sau đó em rpm để càin đặt php và mysql như sau:

Code:

rpm -ivh –relocate=/=/webroot –force \

php-5.1.6-15.Suhosin.i686.rpm \

php-cli-5.1.6-15.Suhosin.i686.rpm \

php-mbstring-5.1.6-15.Suhosin.i686.rpm \

php-common-5.1.6-15.Suhosin.i686.rpm \

php-mysql-5.1.6-15.Suhosin.i686.rpm \

php-pdo-5.1.6-15.Suhosin.i686.rpm \

Tương tự cho mysql.

Sau đó thực hiện các thao tác sau
Code:

mkdir /webroot/var/www/html/www

    mkdir /webroot/tmp/

    chmod 1777 /webroot/tmp/

    mkdir /webroot/etc

    mkdir -p /webroot/var/log/lighttpd

    chown nobody.nobody /webroot/var/log/lighttpd

    mkdir -p /webroot/var/tmp/lighttpd/cache/compress/

    chown nobody.nobody /webroot/var/tmp/lighttpd/cache/compress/

    cp /etc/hosts /webroot/etc/

    cp /etc/nsswitch.conf /webroot/etc/

    cp /etc/resolv.conf /webroot/etc/

    cp /etc/services /webroot/etc/

    cp /etc/localtime /webroot/etc/

    mkdir /webroot/var/run

    mkdir /webroot/var/run/lighttpd

    chown nobody.nobody /webroot/var/run/lighttpd

    mkdir -p /webroot/var/www/html

Tạo một script để copy các libary có nội dung
Code:

1:  #!/bin/bash

       2:  BASE="/webroot"

       3:   

       4:  if [ $# -eq 0 ]; then

       5:    echo "Syntax : $0 /path/to/executable"

       6:    echo "Example: $0 /usr/bin/php5-cgi"

       7:    exit 1

       8:  fi

       9:   

      10:  mkdir -p $BASE$(dirname $1)

      11:  cp $1 $BASE$(dirname $1)

      12:   

      13:  [ ! $BASE ] && mkdir -p $BASE || : 

      14:   

      15:  # iggy ld-linux* file as it is not shared one

      16:  FILES="$(ldd $1 | awk '{ print $3 }' |egrep -v ^'\(')"

      17:   

      18:  echo "Copying shared files/libs to $BASE..."

      19:  for i in $FILES

      20:  do

      21:    d="$(dirname $i)"

      22:    [ ! -d $BASE$d ] && mkdir -p $BASE$d || :

      23:    /bin/cp $i $BASE$d

      24:  done

      25:   

      26:  # copy /lib/ld-linux* or /lib64/ld-linux* to $BASE/$sldlsubdir

      27:  # get ld-linux full file location

      28:  sldl="$(ldd $1 | grep 'ld-linux' | awk '{ print $1}')"

      29:  # now get sub-dir

      30:  sldlsubdir="$(dirname $sldl)"

      31:   

      32:  if [ ! -f $BASE$sldl ];

      33:  then

      34:    echo "Copying $sldl $BASE$sldlsubdir..."

      35:    /bin/cp $sldl $BASE$sldlsubdir

      36:  else

      37:    :

      38:  fi

Sau đó em thực hiện
Code:

/bin2chroot.sh /webroot/usr/bin/php-cgi

Tạo thêm 1 script để lấy các library của các module php có nội dung
Code:

#!/bin/bash

   2:  BASE="/webroot"

   3:   

   4:  if [ $# -eq 0 ]; then

   5:    echo "Syntax : $0 rpm-package"

   6:    echo "Example: $0 php-mysql"

   7:    exit 1

   8:  fi

   9:   

  10:  FILES="$(rpm -ql $1)"

  11:   

  12:  echo "Copying shared files/libs to $BASE..."

  13:  for i in $FILES

  14:  do

  15:    d="$(dirname $i)"

  16:    [ ! -d $BASE$d ] && mkdir -p $BASE$d || :

  17:    /bin/cp $i $BASE$d

  18:    

  19:    LDFILES="$(ldd $i | awk '{ print $3 }' |egrep -v ^'\(')"

  20:          for x in $LDFILES

  21:          do

  22:            echo "Copying $x files/libs to $BASE..."

  23:            y="$(dirname $x)"

  24:            [ ! -d $BASE$y ] && mkdir -p $BASE$y || :

  25:            /bin/cp $x $BASE$y

  26:          done

  27:  done

Và thưc hiện ví dụ:
Code:

./rpm2chroot.sh php-gd

Tiến hành thêm một số dòng config cho lighttpd
Code:

server.chroot = "/webroot"

astcgi.server  = ( ".php" =>

                   ( "localhost" =>

                    (

                     "socket" => "/tmp/php-fastcgi.socket",

                     "bin-path" => "/usr/bin/php-cgi", "min-procs" => 1, "max-procs" => 1,

                     "bin-environment"=>("PHP_FCGI_CHILDREN"=>"256","PHP_FCGI_MAX_REQUESTS"=>"256")

                    )

                   )

                  )

Kết quả: Chạy các file php rất ok, tuy nhiên khi chạy phpmyadmin thì báo lỗi

Code:

Cannot load mysql extension. Please check your PHP configuration. - Documentation
