5. k8s二进制集群之ETCD集群部署

继续上一篇文章《k8s二进制集群之ETCD集群证书生成》下面介绍一下etcd证书生成配置。

下载etcd安装包

https://github.com/etcd-io/etcd/releases/tag/v3.5.9

https://github.com/etcd-io/etcd/releases/download/v3.5.9/etcd-v3.5.9-linux-amd64.tar.gz

tar -zxvf etcd-v3.5.9-linux-amd64.tar.gz

本机安装etcd

cp -p etcd-v3.5.9-linux-amd64/etcd* /usr/local/bin/

其它master节点etcd安装

scp -p etcd-v3.5.9-linux-amd64/etcd* eyinfom2:/usr/local/bin/

scp -p etcd-v3.5.9-linux-amd64/etcd* eyinfom3:/usr/local/bin/

创建etcd配置文件

所有master节点都需要配置，需要根据下面配置项说明依次对每个节点做修改；

ETCD_NAME	集群中节点名称，保证唯一
ETCD_DATA_DIR	数据目录
ETCD_LISTEN_PEER_URLS	集群通信监听地址
ETCD_LISTEN_CLIENT_URLS	客户端访问监听地址
ETCD_INITIAL_ADVERTISE_PEER_URLS	客户端集群通信地址
ETCD_ADVERTISE_CLIENT_URLS	客户端集群访问监听地址
ETCD_INITIAL_CLUSTER	集群节点地址
ETCD_INITIAL_CLUSTER_TOKEN	集群token
ETCD_INITIAL_CLUSTER_STATE	加入集群的当前状态：new-新集群；existing-表示加入已有集群

1. Master 1节点配置项

   mkdir /etc/etcd
   

   cat > /etc/etcd/etcd.conf << "EOF"
   #[Member]
   ETCD_NAME="etcd1"
   ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
   ETCD_LISTEN_PEER_URLS="https://192.168.3.41:2380"
   ETCD_LISTEN_CLIENT_URLS="https://192.168.3.41:2379,http://127.0.0.1:2379"
   
   #[clustering]
   ETCD_INITIAL_ADVERTISE_PEER_URLS="https://192.168.3.41:2380"
   ETCD_ADVERTISE_CLIENT_URLS="https://192.168.3.41:2379"
   ETCD_INITIAL_CLUSTER="etcd1=https://192.168.3.41:2380,etcd2=https://192.168.3.42:2380,etcd3=https://192.168.3.43:2380"
   ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"
   ETCD_INITIAL_CLUSTER_STATE="new"
   EOF
   

2. Master 2节点配置项
