k8s记录-flanneld+docker网络部署（四）

1）程序准备
tar xvf flannel-v0.10.0-linux-amd64.tar.gz
mkdir -p /data/projects/common/kubernetes/{bin,cfg,ssl}
mv flanneld mk-docker-opts.sh kubernetes/bin
以下步骤每一台机器部署注意名称、IP、路径等修改（脚本文件、配置文件）
2）修改配置
flanneld

#!/bin/bash
ETCD_HOME=etcd
ETCD01_IP=192.168.0.1
ETCD02_IP=192.168.0.2
ETCD03_IP=192.168.0.3

FLANNEL_OPTIONS="--etcd-endpoints=https://$ETCD01_IP:2379,https://$ETCD02_IP:2379,https://$ETCD03_IP:2379  -etcd-cafile=$ETCD_HOME/ssl/ca.pem -etcd-certfile=$ETCD_HOME/ssl/server.pem -etcd-keyfile=$ETCD_HOME/ssl/server-key.pem"

3）开启与停止服务
a.开启服务

#/bin/bash
KUBE_HOME=kubernetes

source $KUBE_HOME/cfg/flanneld
sudo nohup $KUBE_HOME/bin/flanneld $FLANNEL_OPTIONS &
sudo $KUBE_HOME/bin/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/docker 

b.停止服务

#/bin/bash
kill -9 ` ps -ef | grep flanneld | grep -v grep | awk '{print $2}'`

4）配置docker

#!/bin/bash
cdir="/app/docker"
mkdir -p $cdir
cd /app/docker
yum -y install libtool-ltdl-devel policycoreutils policycoreutils-python libseccomp pigz container-selinux
rpm -ivh docker-ce-cli-18.09.0-3.el7.x86_64.rpm
rpm -ivh docker-ce-selinux-17.03.3.ce-1.el7.noarch.rpm
rpm -ivh containerd.io-1.2.0-3.el7.x86_64.rpm
rpm -ivh docker-ce-18.09.0-3.el7.x86_64.rpm
systemctl start docker
sleep 5
systemctl stop docker
sleep 5
mv /var/lib/docker/* /data/docker
cd /var/lib
rm -rf docker
ln -s /data/docker /var/lib/docker
ls -l docker
systemctl start docker
usermod -G docker app
systemctl restart docker.service
docker ps –a
cp docker-compose /usr/local/bin
chmod +x /usr/local/bin/docker-compose

修改docker.service
在usr/lib/systemd/system/docker.service“ExecStart”上方加入（注释原来的）
EnvironmentFile=/run/flannel/docker
ExecStart=/usr/bin/dockerd $DOCKER_NETWORK_OPTIONS

systemctl daemon-reload

systemctl restart docker

#验证docker0和flanneld1.1是否在同一网段执行ifconfig
