            I added this lines in HAproxy conf. file:

             listen 
    bind <public IP>:21
    mode tcp  
    server web-second <local IP>:21 check

            Result:

            [root@rp ~]# sudo systemctl restart haproxy
Job for haproxy.service failed because the control process exited with error code. See "systemctl status         haproxy.service" and "journalctl -xe" for details.

              The configuration file has an issue, I am
              reviewing the configuration file. Before restarting running ‘haproxy check’ so you make sure it doesn’t fail on restart.

                You're missing a name declaration beside the listen in the last example that you posted.
                listen <my_service_here>
                and optionally the hostname and bind port:
                listen <my_service_here> localhost:8080

                  I have one "listen" and for statistics.
                  Could you give an example for FTP listen?

                    @emsanator : Check line 81 of your file. The error states that it couldn't find a declaration for listen on that line. (/etc/haproxy/haproxy.cfg:81)
                    I expect that you're missing "listen myftpserver" or similar.

                       listen FTP  
       bind *:21,:10000-10250
       mode tcp 
       server ftp01 192.168.1.4 check port 21
       server ftp02 192.168.1.5 check port 21

                      I do not get HAproxy error with this method

                      FileZilla Log:

                       Status:	Connecting to <Public IP>:21...
 Status:	Connection established, waiting for welcome message...
 Status:	Initializing TLS...
 Status:	Verifying certificate...
 Status:	TLS connection established.
 Status:	Server does not support non-ASCII characters.
 Status:	Logged in
 Status:	Retrieving directory listing...
 Status:	Server sent passive reply with unroutable address. Using server address instead.
 Command:	MLSD
 Error:	The data connection could not be established: ECONNREFUSED - Connection refused by server

                      I tried every way in few days but I can not connect with FTP.

                        As @scottalanmiller mentioned above, you'll have to configure pasv on ftp and ensure your client is configured to use it as well.

                        within vsftpd.conf :

                        pasv_enable=YES
port_enable=YES
pasv_min_port=10000
pasv_max_port=10250
pasv_address=IP.OF.BOUND.INTERFACE
pasv_addr_resolve=NO
