問(wèn)題描述

下面是my.cnf的全部?jī)?nèi)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兩句話(huà)：

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

然后就不能運(yùn)行了

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

問(wèn)題解答

把新加入的兩句話(huà)用#注釋掉試一下，能不能啟動(dòng)（排除新引入配置出錯(cuò)）

運(yùn)行mysqld status查看Mysql當(dāng)前啟動(dòng)狀態(tài)（排除因未關(guān)閉導(dǎo)致無(wú)法啟動(dòng)）

運(yùn)行用戶(hù)權(quán)限是否發(fā)生變化，如之前用root，現(xiàn)在用user（排除權(quán)限問(wèn)題）

如果第一步就可以啟動(dòng)，則說(shuō)明新配置有問(wèn)題，根據(jù)響應(yīng)Mysql版本查一下啟動(dòng)參數(shù)是不是寫(xiě)錯(cuò)，以上。
