安装环境：
Docker容器和宿主机都是CentOS 7.3版本
1. Docker容器内安装ipvsadm
yum install -y ipvsadm # enable IP forward echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf sysctl -p touch /etc/sysconfig/ipvsadm systemctl start ipvsadm systemctl enable ipvsadm
2. Docker宿主机上安装ipvsadm
yum install -y ipvsadm
否则容器内运行ipvsadm会出现如下错误：
Can't initialize ipvs: Protocol not available
Are you sure that IP Virtual Server is built in the kernel or as module? 原文链接：https://www.f2er.com/centos/378172.html
