centos6.5下yum安装mysql5.6
2 接下来就是卸载mysql5.1了，命令：rpm -e mysql-libs --nodeps
3 yum中之后mysql5.1，安装还是5.1，现在就要去增加一个新的repo
命令：rpm -Uvh http://mirror.steadfast.net/epel/6/i386/epel-release-6-8.noarch.rpm
4 一共需要增加两个repo，现在增加另一个
命令：rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
5 现在查看一些是否增加成功了
命令：yum --enablerepo=remi,remi-test list mysql mysql-server
6 接下来就是安装mysql5.56了
命令：yum --enablerepo=remi,remi-test install mysql mysql-server
7出现这个东西的时候一定要选择y。不然神都救不了你，就要重新安装了
8：看到下面这个图片证明你的mysql安装成功了
9 接下来需要启动一下mysql
命令：/etc/init.d/mysqld start
10 下面这条命令设置开机自启动，省的我们每次开机就去启动一下mysql了
命令：chkconfig --levels 345 mysqld on
11 要启用MySQL 安全设置请输入以下命令
命令：/usr/bin/mysql_secure_installation
一直选 y
12 到这里就要验证一下mysql是否安装成功了。如果输入看到以下界面的话，那么你就安装成功了。犒劳一下自己吧。
连接数据库命令：mysql -u用户，-p密码
mysql默认端口是3306，如果需要修改端口
如需要修改端口：
//登陆mysql
[root@pingxiang ~]# mysql -uroot –p
//查看端口
mysql> show global variables like ‘port‘;
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port | 3306 |

//修改etc文件夹下的my.cnf
[root@pingxiang etc]# vi my.cnf

Lunix 允许开放端口：

阿里云允许开放端口：
可百度查询如何设置阿里云允许端口开放（因为我自己用的是阿里云服务器，其他服务器好像不用这样做）
Mysql允许远程连接
先登陆mysql mysql -u用户 -p密码
然后执行命令： grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘;
mysql> grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
好了，可以用navicat连接了，（我用navicat，很方便），祝大家都能一次性安装成功
