Linux 部署或升级openssh7.5p1

运维Linux系统，部署或升级openssh是经常面临的事,以下已redhat6和redhat7为例。

在redhat6中部署openssh会有什么坑,在编辑openssh源码包时会报一些类似的错误，如下：

checking OpenSSL header version... 10000003 (OpenSSL 1.0.0 29 Mar 2010)
     checking OpenSSL library version... configure: error: OpenSSL >= 1.0.1 required (have "10000003 (OpenSSL 1.0.0-fips 29 Mar 2010)")

　 checking OpenSSL header version... not found
     configure: error: OpenSSL version header not found.

这是原因openssh在编辑时加上--without-hardening. 下面是写的一个shell安装openssh的过程. 在redhat7中没有这个问题.
