安装
# 1.查看系统版本
[root@vm-xiluhua][/home/xiluhua]$ cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
# 2.到mysql官网下CentOS 7对应的版本，
2.1.选择社区版（红框）
2.2.点击DOWNLOAD（红框）
2.3.选择Red Hat Enterprise Linux / Oracle Linux（红框）
2.4.选择CentOS 7、64位的，也就是第一个rpm安装包版本（红框）
# 3.将下载的安装包放到上传到/usr/local/mysql文件夹下（自己新建准备），解压缩
[root@vm-xiluhua][/usr/local/mysql]$ tar -xvf mysql-5.7.15-1.el7.x86_64.rpm-bundle.tar
# 3.1.目录结构如下，实际用到的安装包仅为红色部分

# 4.安装（需要使用root账户操作，不然没有权限）
4.1.注意事项：必须依次安装，因为他们之间存在依赖链
4.2.注意事项：尝试使用rpm工具的--prefix或--relocate指定安装目录，系统反馈不允许

# 5.经过以上步骤，安装基本完成，但还需要配置mysql的初始化文件/etc/my.cnf
[root@vm-xiluhua][/usr/local/mysql]$ cd /etc/
[root@vm-xiluhua][/etc]$ less my.cnf
# 6.在my.cnf的[mysqld]代码下方添加skip-grant-tables
[root@vm-xiluhua][/etc]$ vi my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
skip-grant-tables
# 7.启动mysql
[root@vm-xiluhua][/etc]$ service mysqld start
Redirecting to /bin/systemctl start mysqld.service
# 8.验证mysql是否启动
[root@vm-xiluhua][/etc]$ netstat -apln | grep mysql
tcp6 0 0 :::3306 :::* LISTEN 3625/mysqld unix 2 [ ACC ] STREAM LISTENING 92437 3625/mysqld /var/lib/mysql/mysql.sock
# 9.首次登录（第6步[mysqld]代码下方添加skip-grant-tables，目的是为了首次登录时不用输入密码）
[root@vm-xiluhua][/etc]$ mysql

这时，在windows下使用Navicat以root账户连接mysql可以密码为空。
如telnet 3306端口不通，连接不上mysql，请关闭linux服务器防火墙。

至此，完成rpm包安装mysql
卸载
# 1.关闭MySQL服务
[root@vm-xiluhua][/etc]$ service mysqld stop
Redirecting to /bin/systemctl stop mysqld.service
# 2.卸载MySQL软件包
# 2.1.查询系统下的所有mysql软件包
[root@vm-xiluhua][/etc]$ rpm -aq | grep mysql

# 3.删除MySQL安装文件夹
# 再次查看剩下有哪些文件夹

至此，卸载完成
