部署kubernetes1.8.4+contiv高可用集群

原理和架构图参考上一篇，这里只记录操作步骤。

etcd version: 3.2.11
kube version: 1.8.4
docker version: 17.03.2-ce
OS version: debian stretch

三个ETCD节点（contiv插件也要使用etcd，这里每个节点复用跑2个etcd实例）

192.168.5.84 ???etcd0,contiv0192.168.5.85 ???etcd1,contiv1192.168.2.77 ???etcd2,contiv2

两个lvs节点

192.168.2.56 ????master192.168.2.57 ????backup

4个k8s节点（3个master，1个node）

192.168.5.62 ????master01192.168.5.63 ????master02192.168.5.107 ????master03192.168.5.68 ????node

1、部署ETCD，由于这几个节点版本较低，所以没有使用systemd

a、部署k8s使用的etcd集群，直接使用etcd二进制文件启动即可，启动脚本如下：

# cat etcd-start.sh#获取IPlocalip=`ifconfig em2|grep -w inet| awk ‘{print $2}‘|awk -F: ‘{print $2}‘`pubip=0.0.0.0#启动服务etcd --name etcd0 -data-dir /var/lib/etcd ??--initial-advertise-peer-urls http://${localip}:2380 ??--listen-peer-urls http://${localip}:2380 ??--listen-client-urls http://${pubip}:2379 ??--advertise-client-urls http://${pubip}:2379 ??--initial-cluster-token my-etcd-token ??--initial-cluster etcd0=http://192.168.5.84:2380,etcd1=http://192.168.5.85:2380,etcd2=http://192.168.2.77:2380 ??--initial-cluster-state new >> /var/log/etcd.log 2>&1 &

# cat etcd-start.sh#获取IPlocalip=`ifconfig em2|grep -w inet| awk ‘{print $2}‘|awk -F: ‘{print $2}‘`pubip=0.0.0.0#启动服务etcd --name etcd1 -data-dir /var/lib/etcd ??--initial-advertise-peer-urls http://${localip}:2380 ??--listen-peer-urls http://${localip}:2380 ??--listen-client-urls http://${pubip}:2379 ??--advertise-client-urls http://${pubip}:2379 ??--initial-cluster-token my-etcd-token ??--initial-cluster etcd0=http://192.168.5.84:2380,etcd1=http://192.168.5.85:2380,etcd2=http://192.168.2.77:2380 ??--initial-cluster-state new >> /var/log/etcd.log 2>&1 &
