How do I enable MySQL binary logging?

Question

I tried to use simple example of mysql-events package but when i tried to use it , i got this error:

Error: ER_NO_BINARY_LOGGING: You are not using binary logging

so i changed my.cnf:

#
# 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/

but when i tried to restart mysql (using $ sudo service mysql restart) this error has happened:

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

and this is systemctl status mysql.service :

What should i do now and what is my problem?

Answer 1

for UBUNTU

i have to add socketPath : '/var/run/mysqld/mysqld.sock' to dsn variable in code and also correcting /etc/mysql/my.cnf as below :

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[mysqld] #grouping  config options is important
# Must be unique integer from 1-2^32
server-id        = 1
# Row format required for ZongJi
binlog_format    = row
# Directory must exist. This path works for Linux. Other OS may require
#   different path.
log_bin          = /var/log/mysql/mysql-bin.log

and at last restart it with $sudo service mysql restart

for CentOS

i have to add socketPath : '/var/lib/mysql/mysql.sock' to dsn variable in code and also correcting /etc/my.cnf as below :

[mysqld]
# Must be unique integer from 1-2^32
server-id        = 1
# Row format required for ZongJi
binlog_format    = row
# Directory must exist. This path works for Linux. Other OS may require
#   different path.
log_bin          = /var/log/mariadb/mariadb-bin.log

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

and at last restart it with $systemctl restart mariadb

NOTE : CentOS 7 has replaced MySQL with MariaDB. So there is deference between log_bin path of UBUNTU and CentOS .
