2.pmapで未知プログラムの依存ライブラリを確認
[root@~]# objdump -p /usr/local/php/bin/php |grep NEEDED
NEEDED libcrypt.so.1
NEEDED librt.so.1
NEEDED libmysqlclient.so.18
NEEDED libmcrypt.so.4
NEEDED libiconv.so.2
NEEDED libcurl.so.4
NEEDED libm.so.6
NEEDED libdl.so.2
NEEDED libnsl.so.1
NEEDED libxml2.so.2
NEEDED libz.so.1
NEEDED libssl.so.10
NEEDED libcrypto.so.10
NEEDED libpthread.so.0
NEEDED libc.so.6
NEEDED libresolv.so.2
3.pmapで実行中プログラムのプロセスを確認
[root@~/software/pldd]# ps -ef|grep php-fpm
