安裝：

yum install libnl3-devel ipset-devel
yum install -y gcc openssl-devel popt-devel
yum install -y keepalived

查找keepalived配置文件：

rpm -ql keepalived
find / -name keepalived
rpm -qa keepalived

查keepalived日志：

tail -f /var/log/messages
journalctl -u keepalived

查看防火墻開放端口：

firewall-cmd --list-ports

配置防火墻放開keepalived：

firewall-cmd --direct --permanent --add-rule ipv4 filter INPUT 0 --destination 224.0.0.18 --protocol vrrp -j ACCEPT firewall-cmd --direct --permanent --add-rule ipv4 filter OUTPUT 0 --destination 224.0.0.18 --protocol vrrp -j ACCEPT firewall-cmd --reload

放開k8s常用端口：

firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=22/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=7472/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=123/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=2379/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=2380/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=16443/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=1080/tcp --permanent firewall-cmd --direct --permanent --add-rule ipv4 filter INPUT 0 --protocol vrrp -j ACCEPT firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=6443/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=10250-10252/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=30000-32767/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=179/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=5473/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=4789/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=6789/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=3300/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=8080/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=6800-6850/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=443/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=5236/tcp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=4789/udp --permanent firewall-cmd --zone=$(firewall-cmd --get-default-zone) --add-port=9283/tcp --permanent firewall-cmd --reload

keepalived配置文件內容：

vrrp_strict一定要注釋掉！！！否則嚴格檢查會使其報錯

[root@m-1 ~]# cat /etc/keepalived/keepalived.conf !

報錯一：

都是嚴格檢查惹的禍，將其關閉就可以了！

現象：

Apr 07 10:02:33 m-2 Keepalived_vrrp[6689]: Unable to load ipset library - libipset.so.11: cannot open shared object file: No such file …irectory

解決：

yum install libnl3-devel ipset-devel
