centos 7 编译 keepalived-1.1.20.tar.gz ：通过

centos 7 编译 keepalived-1.2.23.tar.gz[-] ：通过

centos 7 编译 keepalived-1.2.24.tar.gz：因为该版本需要【linux/mpls_iptunnel.h】头文件，默认的centos内核不支持，需要升级内核才行

centos 7 编译 keepalived-1.3.9.tar.gz：通过

centos 7 编译 keepalived-1.4.5.tar.gz：通过

centos 7 编译 keepalived-2.0.20.tar.gz：通过

centos 7 编译 keepalived-2.2.0.tar.gz：通过

centos 7 编译 keepalived-2.2.1.tar.gz：通过

centos 7 编译 keepalived-2.2.2.tar.gz[+]：因为子该版本开始，增加了“core: Add nftables_ipvs for optimised virtual_server_group handling.”——即"check_nftables.c"源代码文件，故，需要通过--disable-nftables、或--disable-lvs禁用 即可通过编译

fedora 34 编译 keepalived-1.2.24.tar.gz：会报很多错误 “ multiple definition of `garp_delay'”。原因是符号（此处是 garp_delay）的多重定义 。因此，如果我们确认源代码不规范但逻辑没问题的话，可以强制链器允许多重定义，但只链接第一次出现的代码： ./configure LDFLAGS='-z muldefs'

[root@fedora keepalived-1.2.24]# export LDFLAGS="-z muldefs"
[root@fedora keepalived-1.2.24]# ./configure && make && make install

fedora 34 编译 keepalived-2.2.2.tar.gz[+]：通过
