MySQL 5.5.38安装出现的问题_MySQL

卸掉5.1.73， 安装5.5.38，出现的一些问题。

系统启动、关闭

net start mysql;

net stop mysql;

删除服务：两种方法

sc delete mysql 

mysqld -remove 

安装

mysqld --install mysql --defaults-file="D:/mysql 5.5.38/my.ini"

--install 后面跟的事服务名。

5.5.38与5.1.73中不同之处：

mysqld

5.1.73 default-character-set=utf8

5.5.38 character-set-server=utf8

日志叫法也有区别，记得不是特别清楚

slow_query_log

log_slow_query

另外dir设置出问题也会导致1067系统错误。

#系统基本目录

basedir= C:/srv/mysql-5.5.19
#用户数据目录

datadir= E:/myWeb/mysql5data/data

e it.
