#sudo chmod 644 /etc/my.cnf ?(重要)

3. 错误log分析
问题1:
ERROR 2002 (HY000): Can't connect to localMySQL server through socket '/var/lib/mysql/mysql.sock' (2)
解答:
#sudo service mysql start

问题2:
Warning: World-writable config file '/etc/my.cnf' is ignored
解答:
#sudo chmod 644 /etc/my.cnf

问题3:
表中的字段内容乱码
解答:

在Linux平台,MySQL 5 编辑配置文件/etc/my.cnf,

在[client]后添加:

default-character-set=utf8

在[mysqld]后添加:

default-storage-engine=INNODB
character-set-server=utf8

然后重启MySQL,进入命令行模式验证:

?

mysql> use mydatabase;
mysql> show variables like '%char%';

?
