Linux下安装mysql失败,提示找不到mysqld.sock

mysql会按顺序读取配置文件/etc/my.conf,/etc/mysql/my.conf,/usr/etc/my.con,~/.my.conf

/etc/my.conf中的

[client]

port = 3306

socket = /tmp/mysql.sock

[mysqld]

port = 3306

socket = /tmp/mysql.sock

和/etc/mysql/my.conf中socket=/var/run/mysqld/mysqld.sock 配置重复，导致/etc/mysql/my.conf中的[client]覆盖了/etc/my.conf中的[client]设置，所以连接不正确，就会出现你说的错误

最简单的办法是删除这个文件

mv /etc/mysql/my.conf /etc/mysql/mysql.conf_backup

这个要看安装mysql的配置，默认安装及日志文件如下：

mysql安装

yum -y install  mysql mysql-server mysql-devel

chkconfig --level 35 mysqld  on

/etc/init.d/mysqld  start
