I'm trying to backup mysql database through SSH using PHP. I have made the ssh connection through ssh but I'm not making any progress with the database backup. This is my code :
<?php
if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist");
if(!($con = ssh2_connect("server.hosting.com", 22))){
echo "fail: unable to establish connection\n";
} else {
if(!ssh2_auth_password($con, "user", "password")) {
echo "fail: unable to authenticate\n";
} else {
// allright, we're in!
echo "okay: logged in...\n";
if (!($stream = ssh2_exec($con, 'echo "mysqldump -u userdb -p pass
dbname tablename > mydb_tab.sql"|mysql'))) {
echo "fail: unable to execute command\n";
} else {
// collect returning data from command
stream_set_blocking($stream, true);
$data = "";
while ($buf = fread($stream,4096)) {
$data .= $buf;
}
fclose($stream);
}
}
}
?>
您的命令不正确,应显示为:
mysqldump -h server –uuserdb -ppass dbname > mydb_tab.sql
