安装：

 wget https://oss-cdn.nebula-graph.com.cn/package/3.2.0/nebula-graph-3.2.0.el8.x86_64.rpm

sudo rpm -ivh --prefix=/root/nebula nebula-graph-3.2.0.el8.x86_64.rpm 

 链接数据库：

./nebula-console -addr 127.0.0.1 -port 9669 -u root -p *****

 

 nebula-console

安装

$ sudo rpm -i nebula-graph-studio-3.4.1.x86_64.rpm --prefix=<path>

http://<ip address>:7001

卸载：

$ sudo rpm -e nebula-graph-studio-3.4.1.x86_64

启动

$ bash /usr/local/nebula-graph-studio/scripts/rpm/start.sh

停止

ubuntu开启/关闭防火墙

 

1、Alt+T打开终端，输入sudo ufw status回车，查看防火墙状态，inactive是关闭，active是开启。

2、使用sudo ufw enable开启防火墙。

3、使用sudo ufw disable关闭防火墙。

开放端口：

sudo ufw allow 22

 

 

linux 查看内核版本

• cat /proc/version
• uname -a
• uname -r

解压 .tar.gz

tar -xzvf

 

索引：

CREATE TAG INDEX IF NOT EXISTS node_package_version on Package(version(30));
CREATE TAG INDEX IF NOT EXISTS node_package_id on Package(packageID(60));
CREATE TAG INDEX IF NOT EXISTS node_package_name on Package(package_name(50));
CREATE TAG INDEX IF NOT EXISTS node_package_is_perelease on Package(isPrerelease(10));
CREATE EDGE INDEX IF NOT EXISTS relationship_framework on Target_To(targetFramework(50));

 

 

导入数据：

./nebula-importer --config ./nufix_dataset.yaml

 

 

 

待修改语句：

match p=(nn:Package{packageID:"fluentvalidation@@8.1.0"})-[r:Target_To*4..6]->(m:Package)

where all(a in r where  a.targetFramework contains ".NETCoreApp"  or a.targetFramework in [".NETStandard2.1",".NETStandard2.0"] or a.targetFramework="ALL" or a.targetFramework is null)

and ((not (m)-[]->()) or (m.cache_NETCoreApp31 is not null and (m)-[]->()))

and all (mm in nodes(p) where mm.isPrerelease ="False")

RETURN m.packageID as end_id,m.cache_NETCoreApp31 as cache,nodes(p) as result limit 2000

 

 

杀死进程：

sudo kill -9 《pid》

 

submit job stats

show stats

 

 

提高并发量：

prlimit --nofile=1000000 --pid=$$

 

 

添加属性：

ALTER TAG Package ADD (cache_net50 string, cache_net60 string, cache_NETFramework48 string, cache_NETFramework472 string, cache_NETFramework471 string, cache_NETFramework47 string, cache_NETFramework462 string, cache_NETFramework461 string, cache_NETFramework46 string, cache_NETFramework452 string, cache_NETFramework451 string, cache_NETFramework45 string, cache_NETFramework403 string, cache_NETFramework40 string, cache_NETFramework35 string, cache_NETFramework20 string, cache_NETFramework11 string, cache_NETStandard21 string, cache_NETStandard20 string, cache_NETStandard16 string, cache_NETStandard15 string, cache_NETStandard14 string, cache_NETStandard13 string, cache_NETStandard12 string, cache_NETStandard11 string, cache_NETStandard10 string, cache_NETCoreApp31 string, cache_NETCoreApp30 string, cache_NETCoreApp22 string, cache_NETCoreApp21 string, cache_NETCoreApp20 string, cache_NETCoreApp11 string, cache_NETCoreApp10 string, cache_XamarinAndroid70 string, cache_XamarinAndroid71 string, cache_XamarinAndroid72 string, cache_XamarinAndroid73 string, cache_XamarinAndroid74 string, cache_XamarinAndroid80 string, cache_XamarinAndroid81 string, cache_XamarinAndroid82 string, cache_XamarinAndroid83 string, cache_XamarinAndroid90 string, cache_XamarinAndroid91 string, cache_XamarinAndroid92 string, cache_XamarinAndroid93 string, cache_XamarinAndroid94 string, cache_XamarinAndroid100 string, cache_XamarinAndroid101 string, cache_XamarinAndroid102 string, cache_XamarinAndroid103 string, cache_XamarinAndroid110 string, cache_XamarinAndroid111 string, cache_XamarinAndroid112 string, cache_XamarinAndroid113 string, cache_XamarinAndroid120 string, cache_XamarinAndroid121 string, cache_XamarinAndroid122 string, cache_MonoAndroid46 string, cache_MonoAndroid54 string, cache_MonoAndroid64 string, cache_UAP80 string, cache_UAP81 string, cache_UAP100 string, cache_UAP10016299 string, cache_UAP10019041 string);
