ubuntu+docker搭建etcd集群

ubuntu+docker搭建etcd集群

1 下载compose,使用下面的指令下载compose

sudo curl -L "-s)-$(uname -m)" -o /usr/local/bin/docker-compose

2 将可执行权限应用于二进制文件：

sudo chmod +x /usr/local/bin/docker-compose

创建软链：

wilson@wilson-virtual-machine:~$ sudo chmod +x /usr/local/bin/docker-composewilson@wilson-virtual-machine:~$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-composeln: failed to create symbolic link '/usr/bin/docker-compose': File existswilson@wilson-virtual-machine:~$ lsapp_private_key.pem app_public_key.pem chaincode conf Desktop Documents Downloads dump.rdb go java_error_in_goland_.hprof logs Music mydata mytestfaric Pictures Postman pprof Public snap Templates tomcat Videos cd /usr/local/bin/wilson@wilson-virtual-machine:/usr/local/bin$ lsconfigtxgen consul discover fabric-ca-client idemixgen peer redis-benchmark redis-check-dump redis-sentinel tclsh8.6configtxlator cryptogen docker-compose get-docker-images.sh orderer protoc redis-check-aof redis-cli redis-serverwilson@wilson-virtual-machine:/usr/local/bin$ pwd/usr/local/binwilson@wilson-virtual-machine:/usr/local/bin$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-composeln: failed to create symbolic link '/usr/bin/docker-compose': File existswilson@wilson-virtual-machine:/usr/local/bin$ lsconfigtxgen consul discover fabric-ca-client idemixgen peer redis-benchmark redis-check-dump redis-sentinel tclsh8.6configtxlator cryptogen docker-compose get-docker-images.sh orderer protoc redis-check-aof redis-cli redis-serverwilson@wilson-virtual-machine:/usr/local/bin$ cp docker-compose /usr/bin/cp: cannot create regular file '/usr/bin/docker-compose': Permission deniedwilson@wilson-virtual-machine:/usr/local/bin$ sudo cp docker-compose /usr/bin/

3 测试是否安装成功： 拉取etcd官方镜像

wilson@wilson-virtual-machine:/usr/bin$ docker-compose --versiondocker-compose version 1.24.1, build 4667896bwilson@wilson-virtual-machine:/usr/bin$ cker-compose version 1.24.1cker-compose: command not foundwilson@wilson-virtual-machine:/usr/bin$ docker-compose --versiondocker-compose version 1.24.1, build 4667896bwilson@wilson-virtual-machine:/usr/bin$ cker-compose version 1.24.1cker-compose: command not foundwilson@wilson-virtual-machine:/usr/bin$ docker-compose version 1.24.1Show version informationUsage: version [--short]Options: --short Shows only Compose's version number.wilson@wilson-virtual-machine:/usr/bin$ docker pull quay.io/coreos/etcdUsing default tag: latestlatest: Pulling from coreos/etcdff3a5c916c92: Already exists 96b0e24539ea: Pull complete d1eca4d01894: Pull complete ad732d7a61c2: Pull complete 8bc526247b5c: Pull complete 5f56944bb51c: Pull complete Digest: sha256:5b6691b7225a3f77a5a919a81261bbfb31283804418e187f7116a0a9ef65d21dStatus: Downloaded newer image for quay.io/coreos/etcd:latest

4 在一个文件夹下创建 etcd-compose.yml文件，用于管理etcd容器 ​​​etcd-compost.yml​​

version: '3'services: etcd-node1: image: "quay.io/coreos/etcd" container_name: "etcd-node1" ports: - "12379:2379" - "12380:2380" command: 'etcd -name etcd-node1 -advertise-client-urls -listen-client-urls -listen-peer-urls -initial-cluster-token etcd-cluster -initial-cluster "etcd-node1=-initial-cluster-state new' networks: - "etcd" etcd-node2: image: "quay.io/coreos/etcd" container_name: "etcd-node2" ports: - "22379:2379" - "22380:2380" command: 'etcd -name etcd-node2 -advertise-client-urls -listen-client-urls -listen-peer-urls -initial-cluster-token etcd-cluster -initial-cluster "etcd-node1=-initial-cluster-state new' networks: - "etcd" etcd-node3: image: "quay.io/coreos/etcd" container_name: "etcd-node3" ports: - "32379:2379" - "32380:2380" command: 'etcd -name etcd-node3 -advertise-client-urls -listen-client-urls -listen-peer-urls -initial-cluster-token etcd-cluster -initial-cluster "etcd-node1=-initial-cluster-state new' networks: - "etcd"networks: etcd:

5 启动yml文件
