etcd的安装和配置

[root@localhost zh]# yum install etcd

[root@localhost zh]# service etcd start

//因为我是单节点，所以没有修改我的配置文件，下面默认的配置文件内容
[root@localhost zh]# vim /etc/etcd/etcd.conf
#[Member]

//用etcdctl管理
[root@localhost zh]# etcdctl mkdir /test
[root@localhost zh]# etcdctl ls /
/test
[root@localhost zh]# etcdctl --endpoints  http://localhost:2379 ls /
/test
[root@localhost zh]# etcdctl --endpoints  http://localhost:2379 mkdir /web
[root@localhost zh]# etcdctl --endpoints  http://localhost:2379 set /web/web001 "test"
test
[root@localhost zh]# etcdctl --endpoints  http://localhost:2379 get /web/web001
test

//设置分配给docker的网段
[root@localhost zh]# etcdctl  mk /atomic.io/network/config '{"Network":"172.17.0.0/16", "SubnetMin": "172.17.1.0", "SubnetMax": "172.17.254.0"}'

flannel的下载和配置

[root@localhost zh]# yum install flannel

//这是默认的内容，我没有修改
[root@localhost zh]#  vim /etc/sysconfig/flanneld
# Flanneld configuration options  

# etcd url location.  Point this to the server where etcd runs
FLANNEL_ETCD_ENDPOINTS="http://127.0.0.1:2379"

# etcd config key.  This is the configuration key that flannel queries
# For address range assignment
FLANNEL_ETCD_PREFIX="/atomic.io/network"

# Any additional options that you want to pass
#FLANNEL_OPTIONS=""

[root@localhost zh]# systemctl daemon-reload

[root@localhost zh]# service flanneld start

[root@localhost zh]# service flanneld restart

//查看状态
[root@localhost log]# service flanneld status

//查看日志
[root@localhost log]# flanneld -alsologtostderr

//查看flannel0的ip
[root@localhost zh]# ifconfig flannel0
flannel0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 1472
