Keepalived安装错误一例(make错误)解决方法

安装 Keepalived 如果遇到了 make 错误，可以参考以下解决方法：

1. 确认依赖包已经安装

在编译 Keepalived 之前，需要先安装一些依赖包，如 libnl、libnfnetlink、libnftnl 等。可以使用以下命令进行安装：

yum install -y libnl3-devel libnfnetlink-devel libnftnl-devel

2. 检查错误信息

当出现 make 错误时，需要先查看错误信息，确定具体出错原因。例如，出现类似以下错误信息：

../vrrp/.libs/libvrrp.a(vrrp_proto.o): In function `vrrp_proto_init':
vrrp_proto.c:(.text+0x21f): undefined reference to `nflog_open'
vrrp_proto.c:(.text+0x28c): undefined reference to `nflog_bind_pf'
vrrp_proto.c:(.text+0x2a3): undefined reference to `nflog_unbind_pf'
vrrp_proto.c:(.text+0x2b4): undefined reference to `nflog_close'
collect2: error: ld returned 1 exit status
make[2]: *** [keepalived] Error 1
make[2]: Leaving directory `/root/keepalived-2.1.5/keepalived'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/keepalived-2.1.5'
make: *** [all] Error 2

可以看到是链接错误，找不到 nflog_open、nflog_bind_pf、nflog_unbind_pf 和 nflog_close 函数。这时需要安装 libnetfilter_log-devel 包：

yum install -y libnetfilter_log-devel

3. 重新编译安装

确认依赖包已经安装，错误信息也已经解决后，可以尝试重新编译安装 Keepalived：

make clean
./configure
make
make install

这样就可以成功安装 Keepalived 了。
