【摘要】:地理信息公共服務平臺建設(shè)的核心是以城市空間信息為基礎(chǔ),整合多種類、多尺度、多時相、多分辨率,構(gòu)建數(shù)字城市地理空間框架,提供社會行業(yè)信息整合載體,面向政府部門、企事業(yè)單位和社會公眾提供權(quán)威、豐富、翔實、便捷、快速的在線地理信息服務。根據(jù)地理信息公共服務平臺地理信息服務的高性能需求,本課題對地理信息公共服務平臺集群架構(gòu)展開研究。集群即一組計算機,其中每一臺計算機稱為集群中的一個節(jié)點,這些節(jié)點通過高速網(wǎng)絡(luò)連接起來,統(tǒng)一作為計算機資源,對外部世界形成一個透明的系統(tǒng)映像。 本文以“云南省地理信息公共服務平臺”建設(shè)項目為研究背景,以地理信息公共服務平臺為研究對象,主要研究了地理信息公共服務平臺中的集群架構(gòu)與實現(xiàn)。為了改善地理信息公共服務平臺的服務能力,本文從理論和實踐上探索了一些新技術(shù),并通過對四層集群架構(gòu)的設(shè)計與實現(xiàn),使平臺的服務能力與服務水平得到了改善。 本文所做的主要研究內(nèi)容可以歸納為以下4點: (1) Nginx多web服務器集群架構(gòu)的研究與實現(xiàn)。 (2) ArcGIS server GIS中間件服務器集群的研究與實現(xiàn)。 (3)關(guān)系型數(shù)據(jù)庫Oracle RAC集群的研究與實現(xiàn)。 (4) Memcached集群緩存機制的研究與實現(xiàn)。 通過這四層集群架構(gòu),改善了平臺對海量地理信息數(shù)據(jù)的存取性能問題,以及涉密數(shù)據(jù)的數(shù)據(jù)安全等問題。地理信息公共服務平臺集群架構(gòu)對提高在線地理信息服務性能、提升在線地理信息服務穩(wěn)定性、保障平臺的可擴展性具有重要意義。
[Abstract]:The core of the construction of geographic information public service platform is based on urban spatial information, integrating multi-types, multi-scale, multi-temporal, multi-resolution, constructing digital city geospatial framework, providing social and industrial information integration carrier. For government departments, enterprises and institutions and the public to provide authority, rich, informative, convenient, rapid online geographic information services. According to the high performance requirement of geographic information public service platform, this paper studies the cluster structure of geographic information public service platform. Cluster is a group of computers, in which each computer is called a node in the cluster. These nodes are connected by high-speed networks, unified as computer resources, and form a transparent system image to the outside world. This paper takes the construction project of "Yunnan Province Geographic Information Public Service platform" as the research background, takes the geographical information public service platform as the research object, mainly studies the cluster structure and the realization of the geographical information public service platform. In order to improve the service capability of geographic information public service platform, this paper explores some new technologies in theory and practice, and through the design and implementation of four-tier cluster architecture, the service capability and service level of the platform are improved. The main research contents of this paper can be summarized as follows: (1) the research and implementation of Nginx multi-web server cluster architecture; (2) the research and implementation of) ArcGIS server GIS middleware server cluster. (3) Research and implementation of relational database Oracle RAC cluster. (4) Research and implementation of Memcached cluster cache mechanism. Through the four-layer cluster architecture, the access performance of the platform to the massive geographic information data and the data security of the confidential data are improved. The cluster architecture of geographic information public service platform is of great significance to improve the performance of online geographic information service, improve the stability of online geographic information service, and ensure the expansibility of the platform.
