docker swarm创建副本报错：open /proc/sys/net/ipv4/vs/expire_quiescent_template: no such file or directory“

查看 /var/log/message
完整报错如下：

time=“2023-11-27T23:18:56.742349853+08:00” level=error msg=“error reading the kernel parameter net.ipv4.vs.expire_quiescent_template” error=“open /proc/sys/net/ipv4/vs/expire_quiescent_template: no such file or directory”

解决方法如下：

• 查看是否开启了 ip_vs

    lsmod | grep ip_vs			#无输出则没有开启
  

• 开启 ip_vs

    modprobe ip_vs
  

• 再次查看

    lsmod | grep ip_vs
  

  ip_vs                 145497  0
