apt update && apt -y install make gcc ipvsadm buildessential pkg-config \
automake autoconf libipset-dev libnl-3-dev libnl-genl-3-dev \
libssl-dev libxtables-dev libip4tc-dev libip6tc-dev libmagic-dev libsnmp-dev \
libglib2.0-dev libpcre2-dev libnftnl-dev libmnl-dev libsystemd-dev

下载源码包

1
wget https://keepalived.org/software/keepalived-2.2.8.tar.gz

解压

1
tar xf keepalived-2.2.8.tar.gz && cd keepalived-2.2.8/

./configure --prefix=/usr/local/keepalived --disable-fwmark
#禁用 Keepalived 的 FW_MARK 功能，需配合防火墙打标签实现高级路由和策略
#未禁用该选项 使用nft list ruleset 可看到会生成一个基于nftables的规则集，导致 VIP 无法正常通信
#实际测试我无论是关闭还是未关闭，都会生成防火墙规则集
#需注释 vrrp_strict 可使 VIP 正常通信
#./configure 可用 --help 选项查看其他编译选项

编译安装

1
make && make install

拷贝 service 文件

1
cp -a /root/keepalived-2.2.8/keepalived/keepalived.service /lib/systemd/system/

拷贝 conf 文件

1
mv  /usr/local/keepalived/etc/keepalived/keepalived.conf.sample  /usr/local/keepalived/etc/keepalived/keepalived.conf

启动

1
systemctl damon-reload  &&  systemctl enable --now keepalived

查看版本和编译相关参数，这里可添加路径到默认 PATH ，或软链接

1
/usr/local/keepalived/sbin/keepalived -v
