aliyun centos7.5,安装mysql5.6数据库,navicat 连接数据库
参考整合了 几篇：
1.删除mariadb和mysql
mariadb是mysql的一个分支，但要安装mysql需要删除它
执行rpm -qa|grep mariadb,查看mariadb情况，有就删除 rpm -e -nodeps mariadb....名字
查看是否已经有mysql
rpm -qa |grep mysql 有就删除
--------------------
2、安装的版本：mysql-community-common-5.6.51-2.el7.x86_64
见以下链接：
https://www.cnblogs.com/jiftle/p/6811701.html
前言：由于某些不可抗力，我要在自己的阿里云服务器上搭建hadoop+hive+mysql+tomcat环境，下为mysql的安装记录
→_→大家都知道，centos自带的repo是不会自动更新每个软件的最新版本，所以无法通过yum方式安装MySQL的高级版本。所以，即使我使劲用yum -y install mysql mysql-server mysql-devel，也是没有人会鸟我的。
所以，正确的安装mysql5姿势是要先安装带有可用的mysql5系列社区版资源的rpm包
[root@iZ28gvqe4biZ ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
获取http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
准备中... ################################# [100%]
正在升级/安装...1:mysql-community-release-el7-5 ################################# [100%]这个时候查看当前可用的mysql安装资源：
[root@iZ28gvqe4biZ ~]# yum repolist enabled | grep "mysql.*-community.*"
mysql-connectors-community/x86_64 MySQL Connectors Community 17
mysql-tools-community/x86_64 MySQL Tools Community 31
mysql56-community/x86_64 MySQL 5.6 Community Server 199一般来说，只要安装mysql-server跟mysql-client
这个时候我们可以直接使用yum的方式安装MySQL了
[root@iZ28gvqe4biZ ~]# yum -y install mysql-community-server

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] n
... skipping.
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] n
... skipping.
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!

将host设置为%表示任何ip都能连接mysql，当然也可指定为某个特定ip
