没有/etc/my.conf
可以手动创建或cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
如果手动创建的话,内容如下:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
#user=mysql
character_set_server=utf8
collation-server=utf8_general_ci
#default-character-set=utf8
init_connect='SET NAMES utf8'
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0
