HomeDatabaseMysql TutorialCentOS下MySQL数据库安装

CentOS

前辈们总是说,要边学边记录,要总结。所以,开始把每天学到的内容一点一点记录。

复杂的理论不懂,只会目前安装,安好后就开始玩咯!

1、在官网下载相应的rpm安装包

下载地址: http://dev.mysql.com/downloads/mysql/5.6.html#downloads

比如:我只下载了这三个。

2、鄙人就用rpm命令安装(相对较熟悉)

其实,这是应该是第3步

#rpm -ivh MySQL-client-5.6.19-1.el6.i686.rpm#rpm -ivh MySQL-devel-5.6.19-1.el6.i686.rpm#rpm -ivh MySQL-server-5.6.19-1.el6.i686.rpm

安装后 输入(重启数据库):service mysql restart

出错:mysql  unrecognized service

查了原因,是以前的mysql 没有删除的缘故~~故删之!

3、删除原有的mysql

先查找原来有哪些 rpm -qa|grep mysql

将以上三个一一删除:

删除后再回到步骤2,重新安装。

4、修 改root 密码(这个root账号是mysql的root账号,非Linux的root账号) 。

修改密码输入:#mysqladmin -u root password 'root'  <br>然后又出错(┬_┬)<br>error:‘Access denied for user 'root'@'localhost'’<br>

然后又是百度,使用下面方法可以解决问题:

# service mysql stop#mysqld_safe --user=mysql --skip-grant-tables --skip-networking  mysql -u root mysqlmysql> UPDATE user SET Password=PASSWORD('newpassword(设置新密码)') where USER='root';mysql> FLUSH PRIVILEGES;mysql> quit# /etc/init.d/mysql restart# mysql -uroot -pEnter password: 

5、测试安装是否成功:

输入:mysql> show databases;

分号一定要加,否则会显示出错。

但即使我加了分号后,还是出错了(T^T)

ERROR 1820 (HY00):You must SET PASSWORD before executing this statement

我再一次见证了百度的强大

输入:mysql>  SET PASSWORD = PASSWORD('123456(你的密码)');

重新设置一次密码!

然后,好像真的可以了~~
