啓用在my.cnf

Question

MySQL的二進制日誌我試圖用simple example ofmysql-events package但是當我試圖使用它，我得到這個錯誤：

Error: ER_NO_BINARY_LOGGING: You are not using binary logging

，所以我改變的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/ 

但當我試圖重新啓動mysql（使用$ sudo service mysql restart）發生此錯誤：

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

並且這是systemctl status mysql.service：

我該怎麼做，我的問題是什麼？

Answer 1

的Ubuntu

我要補充socketPath : '/var/run/mysqld/mysqld.sock'在代碼中dsn變量，也如下修正/etc/mysql/my.cnf：與$sudo service mysql restart

!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 

，最後重新啓動它爲CentOS

我要加socketPath : '/var/lib/mysql/mysql.sock'到dsn vari能夠在代碼中，也可以作爲以下修正/etc/my.cnf：

[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 

，並在與$systemctl restart mariadb

最後重新啓動它注意：CentOS的7已經取代MySQL的使用MariaDB。所以在UBUNTU和CentOS之間有log_bin的路徑。
