今天在安装ipvs 出现的问题,其余几个服务器都没问题,我的ipvs 文件如下
创建 /etc/modules-load.d/ipvs.conf 并加入以下内容:
cat >/etc/modules-load.d/ipvs.conf <<EOF
ip_vs
ip_vs_lc
ip_vs_wlc
ip_vs_rr
ip_vs_wrr
ip_vs_lblc
ip_vs_lblcr
ip_vs_dh
ip_vs_sh
ip_vs_fo
ip_vs_nq
ip_vs_sed
ip_vs_ftp
ip_vs_sh
nf_conntrack
ip_tables
ip_set
xt_set
ipt_set
ipt_rpfilter
ipt_REJECT
ipip
EOF
设置为开机启动
systemctl enable --now systemd-modules-load.service
这个时候加入开机启动还有立马启动执行就会报下面错误

答案:
[root@master1 k8s]# chmod 755 /lib/modules/ipvs.modules && bash /lib/modules/ipvs.modules && lsmod | grep ip_vs
modprobe:致命:找不到模块 ip_vs_fo。
大规模地4年前 (2018-12-11)内核未升级

参考:https://github.com/coreos/bugs/issues/2518
好象内核不支持,运行modprobe nf_conntrack就运行
4年前 (2018-12-11 )他的是另外一个模块,是ip_vs_fo找不到,他用的是3.10内核。另外内核nf_conntrack模块的问题已经在1.13.0版本中修复,参考https://github.com-16/Lentil1 issues/14。我的脚中加载的也是nf_conntrack,理应没有问题。

具体原因是内核版本问题,不过也可以将文件中的ip_vs_fo 去掉,然后继续执行
