如何在linux系统的was中启动节点

如何在linux系统的was中启动节点,第1张

1、首先拷贝安装包,分别命名为elasticsearch-6.2.4-001和elasticsearch-6.2.4-002。

2、接着在config目录下的jvm.options的内存设置为512M。

3、分别进入这两个安装文件的目录,修改config目录下的elasticsearch.yml文件。

4、接着启动节点node-001: ./elasticsearch。

5、然后启动节点node-002: ./elasticsearch,就完成了。

首先看一段代码,这段代码意图从docSource中获取第一个表格,并插入docTarget的末尾:

1 var table = (Table)docSource.GetChild(NodeType.Table, 0, true)2 docTarget.FirstSection.Body.ChildNodes.Add(table)

这段代码会抛出异常:“The newChild was created from a different document than the one that created this node.”,这是什么原因呢?

原因是,对于Aspose.Words的Node对象,它的一系列样式和格式的控制,取决于它所在的DocumentBase父对象,这也是很多Aspose.Words对象声明时,必须指定它的DocumentBase参数,比如声明一个Table,应该如下:

1 Document doc=new Document()2 Table table=new Table(doc)

那么,我们有没有办法添加另一个文档中的对象呢?有,必须通过Document.ImportNode方法或者使用NodeImporter对象。

这两种方法思路都是将源文档中的Node导入到目标文档中,再追加Node到合适的位置。

Document.ImportNode

1

/// <summary>2 /// A manual implementation of the

Document.AppendDocument function which shows the general 3 /// steps of

how a document is appended to another. 4 /// </summary>5 ///

<param name="dstDoc">The destination document where to append

to.</param>6 /// <param name="srcDoc">The source

document.</param>7 /// <param name="mode">The import mode

to use when importing content from another document.</param>8

public void AppendDocument(Document dstDoc, Document srcDoc,

ImportFormatMode mode) 9 {10 // Loop through all sections in the

source document. 11 // Section nodes are immediate children of the

Document node so we can just enumerate the Document.12 foreach

(Section srcSection in srcDoc)13 {14 // Because we are

copying a section from one document to another, 15 // it is

required to import the Section node into the destination document.16

// This adjusts any document-specific references to styles, lists,

etc.17 //18 // Importing a node creates a copy of the

original node, but the copy19 // is ready to be inserted into

the destination document.20 Node dstSection =

dstDoc.ImportNode(srcSection, true, mode)21 22 // Now the new

section node can be appended to the destination document.23

dstDoc.AppendChild(dstSection)24 }25 }

NodeImporter

1

public static Document GenerateDocument(Document srcDoc, ArrayList

nodes) 2 { 3 // Create a blank document. 4

Document dstDoc = new Document()5 // Remove the first

paragraph from the empty document. 6

dstDoc.FirstSection.Body.RemoveAllChildren()7 8 // Import

each node from the list into the new document. Keep the original

formatting of the node. 9 NodeImporter importer = new

NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting)10

11 foreach (Node node in nodes)12 {13

Node importNode = importer.ImportNode(node, true)14

dstDoc.FirstSection.Body.AppendChild(importNode)15 }16

17 // Return the generated document.18 return

dstDoc19 }
