TCP连接SysLog Golang拒绝获取连接

I am using syslog on ubuntu 16.4 Operating System in golang to log error like following.

w, err = syslog.Dial("tcp", "localhost:2114", syslog.LOG_ERR, "testapi")

Here I'm getting following error.

dial tcp 127.0.0.1:2114: getsockopt: connection refused

I have already tried following things.

  1. Enable port in firewall with - sudo ufw allow 2114 command.
  2. Disable firewall and tried with that.
  3. Tried other port with above steps.

Any help with will be really appreciated.

Here is the syslog.conf

#  /etc/rsyslog.conf    Configuration file for rsyslog.

#           For more information see
#           /usr/share/doc/rsyslog-doc/html/rsyslog_conf.html
#
#  Default logging rules can be found in /etc/rsyslog.d/50-default.conf

You need to uncomment

#module(load="imtcp")
#input(type="imtcp" port="514")

To provide syslog TCP reception. Once you have do this restart the syslog service and will work.
If you want listen tcp on port 2114 you need to change the input as

input(type="imtcp" port="2114")
