I want to set up a file server with sftp and virtual account,so i use ProFTPD.

system info:red hat enterprise linux 6.8-x86_64

proftpd info:proftpd-1.3.6

OpenSSL 1.0.1e-fips 11 Feb 2013

error: openssl/rand.h: No such file or directory

what i do:

mkdir /usr/local/proftpd
mkdir /etc/proftpd
cd /usr/local/src
wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.6.tar.gz
tar -zxvf proftpd-1.3.6.tar.gz 
cd /usr/local/src/proftpd-1.3.6    
./configure --prefix=/usr/local/proftpd --sysconfdir=/etc/proftpd --enable-openssl --with-modules=mod_sftp
make

Installation

The mod_sftp module is distributed with ProFTPD. For including mod_sftp as a staticly linked module, use:
  $ ./configure --enable-openssl --with-modules=mod_sftp ...
Alternatively, mod_sftp can be built as a DSO module:
  $ ./configure --enable-dso --enable-openssl --with-shared=mod_sftp ...
Then follow the usual steps:
  $ make
  $ make install
Note that if the libsodium library is available, mod_sftp will auto-detect this, which enables other supported algorithms. You can ensure that mod_sftp compiles with the libsodium library like so:
  $ ./configure --enable-openssl --with-modules=mod_sftp ... \
    --with-includes=/path/to/libsodium/include \
    --with-libraries=/path/to/libsodium/lib

Answer 1

The ProFTPD mod_sftp module requires the OpenSSL library; this build error you encountered:

error: openssl/rand.h: No such file or directory

indicates that OpenSSL is not installed on your system.

Before you run ProFTPD's configure script, you need to make sure the OpenSSL development libraries are installed, using e.g.:

$ yum install openssl-dev

Then you can run your build commands for ProFTPD again:

$ ./configure ...
$ make clean
$ make
$ make install

Later, if you find you want to use the mod_sql and mod_sql_mysql modules, then you will need to install the MySQL libraries:

$ yum install mysql-devel mysql-lib

You are not required to provide the location of the MySQL headers (using --with-includes for the ProFTPD configure script); the ProFTPD build system is usually smart enough to find them, assuming a default install.

Putting this altogether, then:

$ mkdir /usr/local/proftpd
$ mkdir /etc/proftpd
$ cd /usr/local/src
$ yum install mysql-devel mysql-lib openssl-dev
$ wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.6.tar.gz
$ tar -zxvf proftpd-1.3.6.tar.gz 
$ cd /usr/local/src/proftpd-1.3.6    
$ ./configure --prefix=/usr/local/proftpd --sysconfdir=/etc/proftpd --enable-openssl --with-modules=mod_sftp:mod_sql:mod_sql_mysql
$ make
$ make install

Hope this helps!
