我正在尝试使用脚本创建 rsnapshot 配置文件，脚本创建文件并将其上传到备份服务器即可。
注意：两台服务器都运行 centos6
一旦我尝试在备份服务器上运行它，就会出现以下错误：
ERROR: /backup/config/rsnapshot_56.conf on line 2:
ERROR: config_version 1.2 - config_version not recognized!

根据错误，可以看到配置文件包含 rsnapshot 中不允许的空格，但该文件没有任何空格？
$argv[1] 等于数据库中的 id。
该 php 如下所示：
$source_file = "temp.conf";
$remote_file = "rsnapshot_".$argv[1].".conf";
$ftp_server = "xxxx";
$ftp_user_name = "xxxx";
$ftp_user_pass = "xxxx";
$config_sql = "SELECT * FROM xxxx WHERE id = ". $argv[1];
$config_result = mysqli_query($con, $config_sql);
$config_row = mysqli_fetch_array($config_result);
# Create/Edit the temp file with the config that is going to be uploaded
$config_file = fopen($source_file, "w+b") or die("Unable to open file!");
$config_content = "";
$config_content .= "config_versiont1.2nn";
$config_content .= "# Path to binariesn";

$config_content .= "excludet.recycle/nn";
$config_content .= "# Backup commands pr foldern";
$config_folders = explode(',',$config_row['folders']);
foreach ($config_folders as $value) {
$config_content .= "backuptrsync://backup@" . $config_row['ip'] . "/".$value."t".$value."/n";
}
fwrite($config_file, $config_content);
fclose($config_file);
# Set up basic connection
$conn_id = ftp_connect($ftp_server);
# login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
# upload the config file
if (ftp_put($conn_id, $remote_file, $source_file, FTP_ASCII)) {
echo "successfully uploaded $source_filen";
}
else {
echo "There was a problem while uploading $source_filen";
}
# close the connection
ftp_close($conn_id);
?>
是因为\t吗？如果是这样的话，可以做些什么呢？
任何帮助，不胜感激。
要解决选项卡不正确的问题，请在生成的文件上使用以下逗号：
sed -i -e 's/r$//' /path/to/rsnapshot.conf
Linux 中的 SED 实用程序将解析和转换文本。
