前言:

      在这里我用的是rpm安装,当然你也可以选择yum install mysql 这种方式。(yum这种安装方式,我自己试了有点问题,于是就用rpm包安装了)

一、安装前准备:

手先需要下载如下的几个包,然后通过ftp上传到服务器中,当然也可以再网上找到源,通过wget命令下载下来。

推荐使用第二种,因为阿里云的服务器上传速度实在是不敢恭维,但是服务器端下载文件到时很快。

[root@AY130701184903434d7bZ mysql]# lsMySQL-client-5.5.30-1.el6.x86_64.rpmMySQL-devel-5.5.30-1.el6.x86_64.rpmMySQL-server-5.5.30-1.el6.x86_64.rpm

二、然后首先安装服务器端

[root@AY130701184903434d7bZ mysql]# rpm -ivh MySQL-server-5.5.30-1.el6.x86_64.rpm  显示如下信息。    warning: MySQL-server-4.0.16-0.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5  Preparing...       ########################################### [100%]  1:MySQL-server     ########################################### [100%]   。。。。。。(省略显示)

同样的方式,安装client端

安装完成后root用户默认密码为空,我们进去可以看到mysql数据库

mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || b3log              || mysql              || performance_schema || test               |+--------------------+5 rows in set (0.02 sec)

use mysql ,然后show tables看到如下表 ,

mysql> show tables;+---------------------------+| Tables_in_mysql           |+---------------------------+| columns_priv              || db                        || event                     || func                      || general_log               || help_category             || help_keyword              || help_relation             || help_topic                || host                      || ndb_binlog_index          || plugin                    || proc                      || procs_priv                || proxies_priv              || servers                   || slow_log                  || tables_priv               || time_zone                 || time_zone_leap_second     || time_zone_name            || time_zone_transition      || time_zone_transition_type || user                      |+---------------------------+24 rows in set (0.00 sec)

查看user表看到如下结果

mysql> select host,user,password from user;+-----------------------+------+-------------------------------------------+| host                                    | user | password |+-----------------------+------+-------------------------------------------+| %                                        | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B || AY130701184903434d7bZ | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B || 127.0.0.1                            | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B || localhost                             | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B || AY130701184903434d7bZ | | |+-----------------------+------+-------------------------------------------+5 rows in set (0.01 sec)

要配置远程登录host里面需要有%,(具体可以google)  
这样就可以了,有登录权限了,但是如果不能创建表或者数据库,那么就是用户权限的问题了。。
