k8s部署之ETCD集群

1.etcd下载

etcd下载地址：https://github.com/coreos/etcd/releases

从github etcd的发布页面选取相应的版本用wget url 来下载如：

wget https://github.com/coreos/etcd/releases/download/v3.3.5/etcd-v3.3.5-linux-amd64.tar.gz

下载完成后用 tar -zxvf etcd-v3.3.5-linux-amd64.tar.gz 文件解压

cd etcd-v3.3.5-linux-amd64 进入目录把etcd etcdctl两个文件复制到要安装的目录 mkdir /var/lib/etcd/

2.etcd配置文件

生成etcd运行时的配置文件

cat > etcd <<EOF

#[Member]

ETCD_NAME="etcd01"

ETCD_DATA_DIR="/var/lib/etcd/default.etcd"

ETCD_LISTEN_PEER_URLS="https://192.168.1.6:2380"

ETCD_LISTEN_CLIENT_URLS="https://192.168.1.6:2379"

#[Clustering]

ETCD_INITIAL_ADVERTISE_PEER_URLS="https://192.168.1.6:2380"

ETCD_ADVERTISE_CLIENT_URLS="https://192.168.1.6:2379"

ETCD_INITIAL_CLUSTER="etcd01=https://192.168.1.6:2380,etcd02=https://192.168.1.7:2380,etcd03=https://192.168.1.8:2380"

ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"

ETCD_INITIAL_CLUSTER_STATE="new"

EOF

3.生成etcd服务配置文件

运行时的配置文件我们生成好了，现在我们来生成etc服务化的 .service文件

cat > etcd.service <<EOF

[Unit]

Description=Etcd Server

After=network.target

After=network-online.target

Wants=network-online.target

[Service]

Type=notify

EnvironmentFile=-/opt/kubernetes/cfg/etcd

ExecStart=/opt/kubernetes/bin/etcd \

--name=${ETCD_NAME} \

--data-dir=${ETCD_DATA_DIR} \

--listen-peer-urls=${ETCD_LISTEN_PEER_URLS} \

--listen-client-urls=${ETCD_LISTEN_CLIENT_URLS},http://127.0.0.1:2379 \

--advertise-client-urls=${ETCD_ADVERTISE_CLIENT_URLS} \

--initial-advertise-peer-urls=${ETCD_INITIAL_ADVERTISE_PEER_URLS} \

--initial-cluster=${ETCD_INITIAL_CLUSTER} \

--initial-cluster-token=${ETCD_INITIAL_CLUSTER} \

--initial-cluster-state=new \

--cert-file=/opt/kubernetes/ssl/server.pem \

--key-file=/opt/kubernetes/ssl/server-key.pem \

--peer-cert-file=/opt/kubernetes/ssl/server.pem \

--peer-key-file=/opt/kubernetes/ssl/server-key.pem \

--trusted-ca-file=/opt/kubernetes/ssl/ca.pem \

--peer-trusted-ca-file=/opt/kubernetes/ssl/ca.pem

Restart=on-failure

LimitNOFILE=65536

[Install]

WantedBy=multi-user.target

EOF

文件生成后我们把文件复制到服务目录去

cp etcd.service /usr/lib/systemd/system

然后就可以启动服务，服务自启

systemctl start etcd

systemctl enable etcd

以这些步骤做完之后我们就可以用我们之前的免密登录来把相关文件复制到其它的服务器，然后修改配置文件启动服务。
至此我们的etcd就可以以集群的方式来运行了
