Hop,
\nJ’ai eu besoin de faire un script un peu \u00e9volu\u00e9 pour jouer avec une base Oracle et des fichiers \u00e0 ramener depuis un serveur distant.
\nBref, j’ai pens\u00e9 au PHP pour faire un truc assez fin, m\u00ealant Oracle et des transferts de fichiers en \u00ab\u00a0scp\u00a0\u00bb.<\/p>\n

Seule difficult\u00e9, installer le module SSH pour PHP. Ce que je d\u00e9cris ici.
\nEnsuite, les bouts de codes exemple sont sur la doc de PHP<\/a>.<\/p>\n

C\u00f4t\u00e9 serveur Debian<\/h1>\n

J’\u00e9tais parti de l’installation PECL directement, \u00e7a plante, il manquait des petits bouts c\u00f4t\u00e9 Debian. Je montre pour l’exemple :<\/p>\n

srv:~# pecl install ssh2 \"channel:\/\/pecl.php.net\/ssh2-0.11.2\"\r\nFailed to download pecl\/ssh2 within preferred state \"stable\", latest release is version 0.11.2, stability \"beta\", use \"channel:\/\/pecl.php.net\/ssh2-0.11.2\" to install\r\ndownloading ssh2-0.11.2.tgz ...\r\nStarting to download ssh2-0.11.2.tgz (22,740 bytes)\r\n........done: 22,740 bytes\r\n[...]\r\nchecking for ssh2 files in default path... not found\r\nconfigure: error: The required libssh2 library was not found.  You can obtain that package from http:\/\/sourceforge.net\/projects\/libssh2\/\r\nERROR: `\/tmp\/pear\/temp\/ssh2\/configure --with-ssh2' failed\r\n<\/pre>\n
Donc, il faut d’abord installer tout \u00e7a :<\/p>\n
srv:~# apt-cache search libssh2\r\nlibnet-ssh2-perl - Perl module for the SSH 2 protocol\r\nlibssh2-1-dbg - SSH2 client-side library (debug package)\r\nlibssh2-1-dev - SSH2 client-side library (development headers)\r\nlibssh2-1 - SSH2 client-side library\r\nlibssh2-php - PHP Bindings for libssh2\r\npython-libssh2 - Python binding for libssh2 library\r\n\r\nsrv:~# aptitude install libssh2-1-dev libssh2-php<\/pre>\n
Installation du module avec PECL<\/h1>\n
On peut donc enfin installer le module :<\/p>\n
srv:~# pecl install ssh2 \"channel:\/\/pecl.php.net\/ssh2-0.11.2\"\r\nFailed to download pecl\/ssh2 within preferred state \"stable\", latest release is version 0.11.2, stability \"beta\", use \"channel:\/\/pecl.php.net\/ssh2-0.11.2\" to install\r\n[...]\r\nBuild process completed successfully\r\nInstalling '\/usr\/lib\/php5\/20090626+lfs\/ssh2.so'\r\ninstall ok: channel:\/\/pecl.php.net\/ssh2-0.11.2\r\nconfiguration option \"php_ini\" is not set to php.ini location\r\nYou should add \"extension=ssh2.so\" to php.ini\r\naladdin:~# grep extension \/etc\/php5 -r\r\n\/etc\/php5\/conf.d\/gd.ini:extension=gd.so\r\n\/etc\/php5\/conf.d\/ssh2.ini:extension=ssh2.so\r\n\/etc\/php5\/conf.d\/snmp.ini:extension=snmp.so<\/pre>\n
L’installation se charge toute seule d’activer l’extension ssh2.so dans les fichiers de conf PHP.<\/p>\n
Exemple de code d’un transfert<\/h1>\n
define (\"SSH_KEY\",\"\/path\/to\/.ssh\/id_dsa\");\r\ndefine (\"SSH_FINGERPRINT\",\"BXXXXXXXXXXXXXXXXXXXXXX81\"); # \u00e0 r\u00e9cup\u00e9rer la premi\u00e8re fois\r\n...\r\n$ssh = ssh2_connect(SSH_SERVER,SSH_PORT);\r\nif (ssh2_fingerprint ($ssh,SSH2_FINGERPRINT_MD5) != SSH_FINGERPRINT) { # bien penser \u00e0 contr\u00f4ler le fingerprint ; c'est dommage de s'en priver !\r\n  echo \"c'est mal\";\r\n}\r\nif (!ssh2_auth_pubkey_file($ssh, SSH_LOGIN, SSH_KEY.\".pub\", SSH_KEY, '')) {\r\n  echo \"authentif par clef rat\u00e9e\";\r\n}\r\n...\r\nif (@ssh2_scp_recv ($ssh, $fich_src, $fich_dest)) {\r\n  echo \"transfert OK\";\r\n}\r\n...\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
