linux下搭建mysql的方式很多，网上也详解了很多种搭建方式，有直接yum的、有rpm的、、总之，“坑”是层出不穷，有相关文件依赖性、权限、GPG keys等等。
本人也在今天搭建了一下、是出“坑”了，所以来记录下。
--------------------------------------------------------------------------------
本次的搭建方式是使用rpm的方式进行搭建。
相关rpm包下载地址：https://pan.baidu.com/s/1ADAJ0p48_3fiOtijSd9QUQ 密码：z1zm（版本5.7）
第一步：将该包上传至服务器，进行解压：
tar -xvf mysql-5.7.16-1.el6.x86_64.rpm-bundle.tar
解压之后会出现若干rpm文件：
mysql-community-client-5.7.16-1.el6.x86_64.rpm
mysql-community-common-5.7.16-1.el6.x86_64.rpm
mysql-community-devel-5.7.16-1.el6.x86_64.rpm
mysql-community-embedded-5.7.16-1.el6.x86_64.rpm
mysql-community-embedded-devel-5.7.16-1.el6.x86_64.rpm
mysql-community-libs-5.7.16-1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.16-1.el6.x86_64.rpm
mysql-community-server-5.7.16-1.el6.x86_64.rpm
mysql-community-test-5.7.16-1.el6.x86_64.rpm
第二步：使用rpm -ivh xxxxx命令进行安装（切记：顺序要保证同步、各个文件安装之间存在依赖性）
1、rpm -ivh mysql-community-common-5.7.16-1.el6.x86_64.rpm、出现如下内容：

ok，第一行是有点端倪出来了，不过第一步安装算是完成。、
2、rpm -ivh mysql-community-libs-*.rpm
这一步、我就遇到坑了，先看下报错原因。
warning: mysql-community-libs-5.7.16-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY error: Failed dependencies: mysql-community-common(x86-64) >= 5.7.9 is needed by mysql-community-libs-5.7.16-1.el6.x86_64
警告行说的报错原因很明显：由于yum安装了旧版本的GPG keys造成的
还有文件依赖性的原因。（都是同一个版本因此确定版本不会错，只能是前者）
解决方案：命令后边加上 --force --nodeps 看下成功日志。

4、rpm -ivh mysql-community-server-5.7.16-1.el6.x86_64.rpm（这一步、也发生了第二步的原因，加上 --force --nodeps 即可，具体报错原因具体对待）

ok、到这一步，就完成linux下mysql的安装了（rpm方式）。
启动mysql服务：
service mysqld start
查询随机初始root密码：
cat /var/log/mysqld.log | grep "temporary password"
登录即可：
mysql -uroot -p
