configure: error:
!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files.
办理步伐：
[[email protected] ~]# yum -y install openssl-devel
[[email protected] ~]# ./configure
[[email protected] ~]# make;make install
编译的时候呈现这个提示，说明keepalived和内核团结了，假如不是这样的，需要加上这个参数./configure --with-kernel-
