etcd——源码编译、部署、集群部署、测试

借一张图

 

1、下载

https://github.com/etcd-io/etcd

git clone https://github.com/etcd-io/etcd.git

 

2、编译

进入etcd目录，

 

mac/linux下，   make clean  &&   make build

在etcd/bin目录下，生成 etcd  etcdctl   etcdutl 三个可执行文件

 

在win10下，不用make的前提下，

go build -o bin\etcd.exe server\main.go

go build -o bin\etcdctl.exe etcdctl\main.go

 

出现\etcd\client\v3 目录下诸多文件报错，这些文件都用的目录引用，

把真实目录 \etcd\tests\integration\clientv3\examples下对应的文件直接替换 D:\git\go\etcd\etcd\client\v3 目录下的，

重新编译即可。

 

3、单节点启动

命令行下：　

etcd -data-dir ~/data.etcd -advertise-client-urls  http://0.0.0.0:2379 -listen-client-urls http://0.0.0.0:2379

在 goland ide 下，加启动参数

--data-dir bin\in-ide.etcd --advertise-client-urls http://0.0.0.0:2379 --listen-client-urls http://0.0.0.0:2379  

 

4、测试

etcdctl member list
etcdctl --endpoints=10.60.80.11:2379 member list

etcdctl --endpoints=10.60.80.11:2379 put foo hihi
etcdctl --endpoints=10.60.80.11:2379 get foo

 

5、win10下集群部署与测试

1、win 10 环境
下载  https://github.com/etcd-io/etcd/releases
解压 etcd-v3.4.20-windows-amd64.zip

2、启动命令见
https://blog.51cto.com/u_10125763/3700481

3、依次启动 start1.bat   start2.bat  start3.bat

4、查看集群状态
etcdctl --endpoints=[192.168.1.32:2379,192.168.1.32:3379,192.168.1.32:4379]   member list

etcdctl --endpoints=[192.168.1.32:2379,192.168.1.32:3379,192.168.1.32:4379]   endpoint health --cluster=true

etcdctl --endpoints=10.60.80.11:2379 member list

5、查看服务发现
etcdctl --endpoints=[192.168.1.32:2379,192.168.1.32:3379,192.168.1.32:4379]   get /game/sanguo-test/server_state/gateway/1660642593870881200
/game/sanguo-test/server_state/gateway/1660642593870881200

start1.bat

.\etcd.exe --name etcd01 ^
--data-dir .\data\etcd01 ^
--advertise-client-urls http://192.168.1.32:2379 ^
--listen-client-urls http://192.168.1.32:2379 ^
--listen-peer-urls http://192.168.1.32:2380 ^
--initial-advertise-peer-urls http://192.168.1.32:2380 ^
--initial-cluster-token etcd-cluster-1 ^
--initial-cluster etcd01=http://192.168.1.32:2380,etcd02=http://192.168.1.32:2381,etcd03=http://192.168.1.32:2382 ^
--initial-cluster-state new

pause

start2.bat

.\etcd.exe --name etcd02 ^
--data-dir .\data\etcd02 ^
--advertise-client-urls http://192.168.1.32:3379 ^
--listen-client-urls http://192.168.1.32:3379 ^
--listen-peer-urls http://192.168.1.32:2381 ^
--initial-advertise-peer-urls http://192.168.1.32:2381 ^
--initial-cluster-token etcd-cluster-1 ^
--initial-cluster etcd01=http://192.168.1.32:2380,etcd02=http://192.168.1.32:2381,etcd03=http://192.168.1.32:2382 ^
--initial-cluster-state new

pause

start3.bat

.\etcd.exe --name etcd03 ^
--data-dir .\data\etcd03 ^
--advertise-client-urls http://192.168.1.32:4379 ^
--listen-client-urls http://192.168.1.32:4379 ^
--listen-peer-urls http://192.168.1.32:2382 ^
--initial-advertise-peer-urls http://192.168.1.32:2382 ^
--initial-cluster-token etcd-cluster-1 ^
--initial-cluster etcd01=http://192.168.1.32:2380,etcd02=http://192.168.1.32:2381,etcd03=http://192.168.1.32:2382 ^
--initial-cluster-state new

pause

 

6、mac/linux下集群部署

创建执行文件

touch etcd-static.sh

在每个etcd节点上，指定集群成员：

# 指定集群token
# 如果你所在的网络环境配置了多个etcd集群，为了避免意外发生，
# 最好使用-initial-cluster-token参数为每个集群单独配置一个token认证。
# 这样就可以确保每个集群和集群的成员都拥有独特的ID。
TOKEN=token-01

CLUSTER_STATE=new

NAME_1=etcd-node-1
NAME_2=etcd-node-2
NAME_3=etcd-node-3

HOST_1=10.60.100.21
HOST_2=10.60.100.21
HOST_3=10.60.100.21

PORT_1_CLIENT=2379
PORT_2_CLIENT=2479
PORT_3_CLIENT=2579

PORT_1_MEMBER=2380
PORT_2_MEMBER=2381
PORT_3_MEMBER=2382

CLUSTER=${NAME_1}=http://${HOST_1}:${PORT_1_MEMBER},${NAME_2}=http://${HOST_2}:${PORT_2_MEMBER},${NAME_3}=http://${HOST_3}:${PORT_3_MEMBER}

ETCD_SERVER=/Users/admin/Documents/git/go/etcd/etcd/bin/etcd

 

每个节点添加一下各节点对应启动命令行：

etcd-node-1.sh

${ETCD_SERVER} --data-dir=data.etcd/${NAME_1} --name ${NAME_1} \
    --initial-advertise-peer-urls http://${HOST_1}:${PORT_1_MEMBER} --listen-peer-urls http://${HOST_1}:${PORT_1_MEMBER} \
    --advertise-client-urls http://${HOST_1}:${PORT_1_CLIENT} --listen-client-urls http://${HOST_1}:${PORT_1_CLIENT} \
    --initial-cluster ${CLUSTER} \
    --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN} 

etcd-node-2.sh

${ETCD_SERVER} --data-dir=data.etcd/${NAME_2} --name ${NAME_2} \
     --initial-advertise-peer-urls http://${HOST_2}:${PORT_2_MEMBER} --listen-peer-urls http://${HOST_2}:${PORT_2_MEMBER} \
     --advertise-client-urls http://${HOST_2}:${PORT_2_CLIENT} --listen-client-urls http://${HOST_2}:${PORT_2_CLIENT} \
     --initial-cluster ${CLUSTER} \
     --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}  
   

etcd-node-3.sh

${ETCD_SERVER} --data-dir=data.etcd/${NAME_3} --name ${NAME_3} \
     --initial-advertise-peer-urls http://${HOST_3}:${PORT_3_MEMBER} --listen-peer-urls http://${HOST_3}:${PORT_3_MEMBER} \
     --advertise-client-urls http://${HOST_3}:${PORT_3_CLIENT} --listen-client-urls http://${HOST_3}:${PORT_3_CLIENT} \
     --initial-cluster ${CLUSTER} \
     --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN} 

 

查看集群状态

etcdctl --endpoints=[10.60.100.21:2379,10.60.100.21:2479,10.60.100.21:2579]   member list

etcdctl --endpoints=[10.60.100.21:2379,10.60.100.21:2479,10.60.100.21:2579]   endpoint health --cluster=true

 

7、etcdctl命令备份

./etcdctl --endpoints=my-etcd-0.com:2379  get --prefix /
./etcdctl --endpoints=my-etcd-0.com:2379  get --prefix ""
./etcdctl --endpoints=my-etcd-0.com:2379  endpoint health
./etcdctl --endpoints=my-etcd-0.com:2379  get member list
./etcdctl --endpoints=[my-etcd-0.com:2379,my-etcd-1.com:2379,my-etcd-2.com:2379] get --prefix ""

cd /Users/admin/Documents/git/go/etcd/etcd/bin
pwd
echo "./etcdctl  get / --prefix --endpoints=100.6.9.9:2379 "
echo ""
echo "================="
echo ""
./etcdctl  get / --prefix --endpoints=100.6.9.9:2379 
echo "./etcdctl  get / --prefix --endpoints=100.6.9.9:2379   | grep game"
