Question

我已经通过Homebrew在Mac OSX上安装了MySQL 5.6.15。

我已将以下行添加到my.cnf以启用查询日志记录，但MySQL服务器无法使用新行重新启动。我们如何解决这个问题？

已添加到my.cnf

general_log=1
log=/var/log/mysql-query.log

错误：

Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/me-MacBook-Air.local.pid).

整个my.cnf

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

[mysqld]

general_log=1
log=/var/log/mysql-query.log

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

Answer 1

log选项为deprecated since 5.6.1，您使用的是5.6.15。

改为使用general_log_file：

general_log_file=/var/log/mysql-query.log

Answer 2

日志文件路径中缺少引号（可能对新手有用）

，my.cnf中的确切配置是：

# General Query Log
general_log=1
general_log_file="/var/log/mysql-query.log"

Answer 3

MySQL 5.6版本中存在错误。甚至mysqld显示为：

    Default options are read from the following files in the given order:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf c:\Program Files (x86)\MySQL\MySQL Server 5.6\my.ini c:\Program Files (x86)\MySQL\MySQL Server 5.6\my.cnf

真正的设置按以下顺序阅读：

    Default options are read from the following files in the given order:
C:\ProgramData\MySQL\MySQL Server 5.6\my.ini C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf c:\Program Files (x86)\MySQL\MySQL Server 5.6\my.ini c:\Program Files (x86)\MySQL\MySQL Server 5.6\my.cnf

检查文件：“C：\ ProgramData \ MySQL \ MySQL Server 5.6 \ my.ini”

希望对某人有所帮助。

启用MySQL 5.6登录会阻止服务器启动
