由于公司业务并发比较高需要高可用使用LVS keeplived。在linux系统centos6.5版本中安装keeplived时，需要安装penssl-devel依赖包，但是服务器是不允许连接外网（互联网）的，无法使用yum命令进行安装操作，所以本人研究了一下如何在离线状态下安装penssl-devel依赖包。感觉很多坑，所以分享一下个人总结。
在没有安装openssl-devel依赖包时，进行安装keeplived时可能出现的错误信息：
一：提示openssl未正确安装错误信息如下：
configure: error:
!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files. !!!
二：提示OpenSSL MD5库是必需的错误信息如下：
configure: error: OpenSSL MD5 libraries are required
为了查找安装openssl-devel包时所需要的其他依赖包（此步大家可以跳过，直接浏览下一步），本人专门搞了个可以连接外网的服务器，执行yum install -y openssl openssl-devel命令，输出日志如下：

授予download-packages.sh文件执行权限，并执行脚本命令，具体如下：
[root@yoodb openssl-devel-packages]# chmod 777 download-packages.sh
[root@yoodb openssl-devel-packages]# ./download-packages.sh
执行完成后，目录下会存在openssl-devel所需要的依赖包，依赖包信息如下：

另一种方式离线安装openssl-devel依赖包，就是将Redhat ISO文件当做yum本地数据源，配置完成后，直接使用yum install -y openssl openssl-devel命令。
上述问题解决成功后，继续执行./configure --prefix=/usr/local/keepalived命令，报“*** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS.”错误，解决方案：Keepalived-1.3.5编译安装步骤和启动方式详解：https://blog.yoodb.com/yoodb/article/detail/1378
