How do I enable MySQL binary logging?
<p>I tried to use <a href="https://www.npmjs.com/package/mysql-events#quick-start" rel="nofollow noreferrer">simple example of </a> <a href="https://www.npmjs.com/package/mysql-events" rel="nofollow noreferrer">mysql-events package</a> but when i tried to use it , i got this error:</p>

<blockquote>
  <p>Error: ER_NO_BINARY_LOGGING: You are not using binary logging</p>
</blockquote>

<p>so i changed my.cnf:</p>

<pre><code>#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

#
# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
#

#what i added:
log_bin = "/home/erfan/salone-entezar/server/"


!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/

<p>but when i tried to restart mysql (using <code>$ sudo service mysql restart</code>) this error has happened:</p>

<blockquote>
  <p>Job for mysql.service failed because the control process exited with error code.
  See "systemctl status mysql.service" and "journalctl -xe" for details.</p>
</blockquote>

<p>and this is <code>systemctl status mysql.service</code> :</p>
