修改my.cnf后mysql无法运行？？？

问题描述

下面是my.cnf的全部内容：

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

然后加入修改字符的两句话：

[mysql]default-character-set=utf8[mysqld]character-set-server=utf8

然后就不能运行了

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ’/var/run/mysqld/mysqld.sock’ (2)

问题解答

把新加入的两句话用#注释掉试一下，能不能启动（排除新引入配置出错）

运行mysqld status查看Mysql当前启动状态（排除因未关闭导致无法启动）

运行用户权限是否发生变化，如之前用root，现在用user（排除权限问题）

如果第一步就可以启动，则说明新配置有问题，根据响应Mysql版本查一下启动参数是不是写错，以上。
