1、下载etcd软件包
[root@linux-node1 src]# tar -zxvf etcd-v3.2.18-linux-amd64.tar.gz
[root@linux-node1 src]# cd etcd-v3.2.18-linux-amd64
[root@linux-node1 etcd-v3.2.18-linux-amd64]# cp etcd etcdctl /opt/kubernetes/bin/
[root@linux-node1 etcd-v3.2.18-linux-amd64]# scp etcd etcdctl 192.168.43.22:/opt/kubernetes/bin/
[root@linux-node1 etcd-v3.2.18-linux-amd64]# scp etcd etcdctl 192.168.43.23:/opt/kubernetes/bin/
2、创建etcd证书签名请求
[root@linux-node1 ~]# cd /usr/local/src/ssl/
[root@linux-node1 ssl]# vim etcd-csr.json
{
"CN": "etcd",
"hosts": [
"127.0.0.1",
"192.168.43.21",
"192.168.43.22",
"192.168.43.23"
],
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "BeiJing",
"L": "BeiJing",
"O": "k8s",
"OU": "System"
}
]
}
3、生成etcd证书和私钥
[root@linux-node1 ssl]# cfssl gencert -ca=/opt/kubernetes/ssl/ca.pem \
> -ca-key=/opt/kubernetes/ssl/ca-key.pem \
> -config=/opt/kubernetes/ssl/ca-config.json \
> -profile=kubernetes etcd-csr.json | cfssljson -bare etcd
[root@linux-node1 ssl]# ls -l etcd*
-rw-r--r-- 1 root root 1062 Jun 11 00:28 etcd.csr
-rw-r--r-- 1 root root 287 Jun 11 00:26 etcd-csr.json
-rw------- 1 root root 1679 Jun 11 00:28 etcd-key.pem
-rw-r--r-- 1 root root 1436 Jun 11 00:28 etcd.pem
4、将证书移动到opt/kubernetes/ssl目录下
[root@linux-node1 ssl]# cp etcd*.pem /opt/kubernetes/ssl
[root@linux-node1 ssl]# scp etcd*.pem 192.168.43.22:/opt/kubernetes/ssl
[root@linux-node1 ssl]# scp etcd*.pem 192.168.43.23:/opt/kubernetes/ssl
5、设置ETCD配置文件
[root@linux-node1 ssl]# vim /opt/kubernetes/cfg/etcd.conf
#[member]
ETCD_NAME="etcd-node1"
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
#ETCD_SNAPSHOT_COUNTER="10000"
#ETCD_HEARTBEAT_INTERVAL="100"
#ETCD_ELECTION_TIMEOUT="1000"
ETCD_LISTEN_PEER_URLS="https://192.168.43.21:2380"
ETCD_LISTEN_CLIENT_URLS="https://192.168.43.21:2379,https://127.0.0.1:2379"
#ETCD_MAX_SNAPSHOTS="5"
#ETCD_MAX_WALS="5"
#ETCD_CORS=""
#[cluster]
ETCD_INITIAL_ADVERTISE_PEER_URLS="https://192.168.43.21:2380"
# if you use different ETCD_NAME (e.g. test),
# set ETCD_INITIAL_CLUSTER value for this name, i.e. "test=http://..."
ETCD_INITIAL_CLUSTER="etcd-node1=https://192.168.43.21:2380,etcd-node2=https://192.168.43.22:2380,etcd-node3=https://192.168.43.23:2380"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="k8s-etcd-cluster"
ETCD_ADVERTISE_CLIENT_URLS="https://192.168.43.21:2379"
#[security]
CLIENT_CERT_AUTH="true"
ETCD_CA_FILE="/opt/kubernetes/ssl/ca.pem"
ETCD_CERT_FILE="/opt/kubernetes/ssl/etcd.pem"
ETCD_KEY_FILE="/opt/kubernetes/ssl/etcd-key.pem"
PEER_CLIENT_CERT_AUTH="true"
ETCD_PEER_CA_FILE="/opt/kubernetes/ssl/ca.pem"
ETCD_PEER_CERT_FILE="/opt/kubernetes/ssl/etcd.pem"
ETCD_PEER_KEY_FILE="/opt/kubernetes/ssl/etcd-key.pem"
6、创建ETCD系统服务
[root@linux-node1 ~]# vim /etc/systemd/system/etcd.service
[Unit]
Description=Etcd Server
After=network.target
[Service]
Type=simple
WorkingDirectory=/var/lib/etcd
EnvironmentFile=-/opt/kubernetes/cfg/etcd.conf
# set GOMAXPROCS to number of processors
ExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /opt/kubernetes/bin/etcd"
Type=notify
[Install]
WantedBy=multi-user.target
7、重新加载系统服务，并修改node1、node2节点的etcd.conf的配置文件为自己本机的主机名、IP
[root@linux-node1 ~]# systemctl daemon-reload
[root@linux-node1 ~]# systemctl enable etcd
[root@linux-node1 ssl]# scp /opt/kubernetes/cfg/etcd.conf 192.168.43.22:/opt/kubernetes/cfg/
[root@linux-node1 ssl]# scp /etc/systemd/system/etcd.service 192.168.43.22:/etc/systemd/system/
[root@linux-node1 ssl]# scp /opt/kubernetes/cfg/etcd.conf 192.168.43.23:/opt/kubernetes/cfg/
[root@linux-node1 ssl]# scp /etc/systemd/system/etcd.service 192.168.43.23:/etc/systemd/system/
[root@linux-node2 ~]# vim /opt/kubernetes/cfg/etcd.conf
#[member]
ETCD_NAME="etcd-node2"
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
#ETCD_SNAPSHOT_COUNTER="10000"
#ETCD_HEARTBEAT_INTERVAL="100"
#ETCD_ELECTION_TIMEOUT="1000"
ETCD_LISTEN_PEER_URLS="https://192.168.43.22:2380"
ETCD_LISTEN_CLIENT_URLS="https://192.168.43.22:2379,https://127.0.0.1:2379"
#ETCD_MAX_SNAPSHOTS="5"
#ETCD_MAX_WALS="5"
#ETCD_CORS=""
#[cluster]
ETCD_INITIAL_ADVERTISE_PEER_URLS="https://192.168.43.22:2380"
# if you use different ETCD_NAME (e.g. test),
# set ETCD_INITIAL_CLUSTER value for this name, i.e. "test=http://..."
ETCD_INITIAL_CLUSTER="etcd-node1=https://192.168.43.21:2380,etcd-node2=https://192.168.43.22:2380,etcd-node3=https://192.168.43.23:2380"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="k8s-etcd-cluster"
ETCD_ADVERTISE_CLIENT_URLS="https://192.168.43.22:2379"
#[security]
CLIENT_CERT_AUTH="true"
ETCD_CA_FILE="/opt/kubernetes/ssl/ca.pem"
ETCD_CERT_FILE="/opt/kubernetes/ssl/etcd.pem"
[root@linux-node3 ~]# vim /opt/kubernetes/cfg/etcd.conf
#[member]
ETCD_NAME="etcd-node3"
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
#ETCD_SNAPSHOT_COUNTER="10000"
#ETCD_HEARTBEAT_INTERVAL="100"
#ETCD_ELECTION_TIMEOUT="1000"
ETCD_LISTEN_PEER_URLS="https://192.168.43.23:2380"
ETCD_LISTEN_CLIENT_URLS="https://192.168.43.23:2379,https://127.0.0.1:2379"
#ETCD_MAX_SNAPSHOTS="5"
#ETCD_MAX_WALS="5"
#ETCD_CORS=""
#[cluster]
ETCD_INITIAL_ADVERTISE_PEER_URLS="https://192.168.43.23:2380"
# if you use different ETCD_NAME (e.g. test),
# set ETCD_INITIAL_CLUSTER value for this name, i.e. "test=http://..."
ETCD_INITIAL_CLUSTER="etcd-node1=https://192.168.43.21:2380,etcd-node2=https://192.168.43.22:2380,etcd-node3=https://192.168.43.23:2380"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="k8s-etcd-cluster"
ETCD_ADVERTISE_CLIENT_URLS="https://192.168.43.23:2379"
#[security]
CLIENT_CERT_AUTH="true"
ETCD_CA_FILE="/opt/kubernetes/ssl/ca.pem"
ETCD_CERT_FILE="/opt/kubernetes/ssl/etcd.pem"
在所有节点创建etcd存储目录并启动etcd，默认是不会创建的。
[root@linux-node1 ~]# mkdir /var/lib/etcd
[root@linux-node2 ~]# mkdir /var/lib/etcd
[root@linux-node3 ~]# mkdir /var/lib/etcd
[root@linux-node1 ~]# systemctl daemon-reload
[root@linux-node1 ~]# systemctl enable etcd
[root@linux-node2 ~]# systemctl daemon-reload
[root@linux-node2 ~]# systemctl enable etcd
[root@linux-node3 ~]# systemctl daemon-reload
[root@linux-node3 ~]# systemctl enable etcd
[root@linux-node1 ~]# systemctl start etcd
[root@linux-node2 ~]# systemctl start etcd
[root@linux-node3 ~]# systemctl start etcd
8、验证集群
[root@linux-node1 ~]# etcdctl --endpoints=https://192.168.43.21:2379 \
> --ca-file=/opt/kubernetes/ssl/ca.pem \
> --cert-file=/opt/kubernetes/ssl/etcd.pem \
> --key-file=/opt/kubernetes/ssl/etcd-key.pem cluster-health
member 6617b5aaafae24e4 is healthy: got healthy result from https://192.168.43.23:2379
member bb1998338f4e535e is healthy: got healthy result from https://192.168.43.21:2379
member dcf594c5976bb617 is healthy: got healthy result from https://192.168.43.22:2379
cluster is healthy
