１.首先安装docker和docker-compose:
docker:
curl -sSL https://get.daocloud.io/docker | sh
将当前用户添加到docker用户组:
sudo gpasswd -a ${USER} docker
su root 切换到root用户
su yifan 再切换到原来的应用用户以上配置才生效docker-compose:
apt remove docker-compose
pip install docker-compose -i https://mirrors.aliyun.com/pypi/simple/
在.bashrc中增加
export PATH="/home/yifan/.local/bin":$PATH
2. 编写docker-compose:
version: "3"
services:
zero:
image: dgraph/dgraph:latest
volumes:
- ./data0/data-volume:/dgraph
ports:
- 5080:5080
- 6080:6080
command: dgraph zero --my=zero:5080 --replicas 3
server_1:
image: dgraph/dgraph:latest
hostname: "server_1"
volumes:
- ./data1/data-volume:/dgraph
ports:
- 8080:8080
- 9080:9080
command: dgraph alpha --my=server_1:7080 --lru_mb=2048 --zero=zero:5080
server_2:
image: dgraph/dgraph:latest
hostname: "server_2"
volumes:
- ./data2/data-volume:/dgraph
ports:
- 8081:8081
- 9081:9081
command: dgraph alpha --my=server_2:7081 --lru_mb=2048 --zero=zero:5080 -o 1
server_3:
image: dgraph/dgraph:latest
hostname: "server_3"
volumes:
- ./data3/data-volume:/dgraph
ports:
- 8082:8082
- 9082:9082
command: dgraph alpha --my=server_3:7082 --lru_mb=2048 --zero=zero:5080 -o 2
ratel:
image: dgraph/dgraph:latest
hostname: "ratel"
ports:
- 8000:8000
command: dgraph-ratel
3.启动docker-compose:
docker-compose up -d
4.查看界面:
http://localhost:8000

运行
1) 添加数据
{
set {
_:luke <name> "Luke Skywalker" . _:leia <name> "Princess Leia" . _:han <name> "Han Solo" . _:lucas <name> "George Lucas" . _:irvin <name> "Irvin Kernshner" . _:richard <name> "Richard Marquand" . _:sw1 <name> "Star Wars: Episode IV - A New Hope" . _:sw1 <release_date> "1977-05-25" . _:sw1 <revenue> "775000000" . _:sw1 <running_time> "121" . _:sw1 <starring> _:luke . _:sw1 <starring> _:leia . _:sw1 <starring> _:han . _:sw1 <director> _:lucas . _:sw2 <name> "Star Wars: Episode V - The Empire Strikes Back" . _:sw2 <release_date> "1980-05-21" . _:sw2 <revenue> "534000000" . _:sw2 <running_time> "124" . _:sw2 <starring> _:luke . _:sw2 <starring> _:leia . _:sw2 <starring> _:han . _:sw2 <director> _:irvin . _:sw3 <name> "Star Wars: Episode VI - Return of the Jedi" . _:sw3 <release_date> "1983-05-25" . _:sw3 <revenue> "572000000" . _:sw3 <running_time> "131" . _:sw3 <starring> _:luke . _:sw3 <starring> _:leia . _:sw3 <starring> _:han . _:sw3 <director> _:richard . _:st1 <name> "Star Trek: The Motion Picture" . _:st1 <release_date> "1979-12-07" . _:st1 <revenue> "139000000" . _:st1 <running_time> "132" . } }
拷贝到命令行，切换到mutate，然后run
2) 添加索引
name: string @index(term) . release_date: datetime @index(year) . revenue: float . running_time: int .
拷贝到命令行，切换到alter，然后run
3) 查询
{
me(func:allofterms(name, "Star Wars")) @filter(ge(release_date, "1980")) { name release_date revenue running_time director { name } starring { name } } }
拷贝到命令行，切换到query，然后run
