$ sudo ln -s your_path/images /var/www/html
$ sudo chmod 755 images

注:亟待保证images的装有父目录都有权力,同不经常候images的不二等秘书技应该是全路径。

5. Maven settings.xml

settings.xml是Maven最重要的计划文件,它平时位于多个地方:

  • Maven安装的主目录: $MAVEN_HOME/conf/settings.xml

  • 顾客主目录: $USEPRADO_HOME/.m2/settings.xml

率先个setting.xml称为全局配置文件,第三个名字为客户配置。假使七个文件相同的时间设有,它们的剧情将会计统计意气风发,客户配置将会覆盖全局配置。

上面包车型地铁原委翻译自Maven安装时的settings.xml文件:

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <!--设置本地仓库存储路径。默认路径为${user.home}/.m2/repository。 -->
  <localRepository>${user.home}/.m2/repository</localRepository>

  <!--设置用户输入时是Maven是否进行交互。如果设置为false,对于问题的参数Maven会使用一个合理的默认值,也可能是基于其它设置的。默认值为true。-->
  <interactiveMode>true</interactiveMode>

  <!--设置Maven执行build时是否连接网络。这会影响工件的下载,部署和其它。默认值为false(联网)。 -->
  <offline>false</offline>

  <!-- 
    这是一个组标识符列表,当通过插件的前缀解析插件时会搜索这个列表,例如,调用命令行"mvn prefix:goal"时。如果没有包含在这个列表里,Maven会自动的添加组标识符"org.apache.maven.plugins" 和"org.codehaus.mojo"。 这个元素包括一系列的pluginGroup元素,每一个子元素都包含一个groupId。当一个插件被使用,并且没有在命令行上提供的时候,插件组列表就会被查找。
  -->
  <pluginGroups>
    <!-- 指定插件查找的组标识符 -->
    <pluginGroup>com.your.plugins</pluginGroup>
  </pluginGroups>

  <!-- 设置本机连接网络的代理服务器列表。除非另外规定(系统属性或命令行转换),否则将激活并使用列表中的第一个代理。-->
  <proxies>
    <!-- 配置代理服务器的相关参数 -->
    <!-- 协议://主机名:端口 -->
    <!-- 用户名-密码 -->
    <proxy>
      <!-- 代理标识符,用来区分代理。 -->
      <id>optional</id>
      <!-- 指定是否激活 -->
      <active>true</active>
      <!-- 指定代理协议 -->
      <protocol>http</protocol>
      <!-- 指定代理认证的用户名 -->
      <username>username</username>
      <!-- 指定代理认证的密码 -->
      <password>pwd</password>
      <!-- 指定代理服务器的主机名 -->
      <host>proxy.host.net</host>
      <!-- 指定代理服务的端口 -->
      <port>80</port>
      <!-- 指定不被代理的主机名列表。多个用|分隔。-->
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
  </proxies>

  <!-- 
    当连接一个特定的服务器时,指定要使用的认证信息,在系统内部通过唯一的名字来标识(引用下面的id属性),你该指定username/password或privateKey/passphrase,它们是成对使用的。
  -->
  <servers>
    <!-- 例子一 用户名/密码-->
    <server>
      <!-- server的id(注意不是用户登陆的id)。该id与distributionManagement中repository元素的id必须要匹配。-->
      <id>deploymentRepo</id>
      <!-- 服务器认证的用户名 -->
      <username>repouser</username>
      <!-- 服务器认证的用户对应的密码 -->
      <password>repopwd</password>
    </server>

    <!-- 例子二 私钥/密码 -->
    <server>
      <id>siteServer</id>
      <!-- 认证用的私钥文件 -->
      <privateKey>/path/to/private/key<</privateKey>
      <!-- 认证用的私钥密码,没有密码就为空 -->
      <passphrase>optional;leave empty if not used.</passphrase>
    </server>
  </servers>

  <!-- 
    这是用来从远端仓库下载artifact的镜像列表。它的机制类似于这一:POM文件可能在解析特定的artifacts时会声明一个仓库。但这个仓库可能有时会有拥堵问题,因此必须在其它的几个地方放置几个它的镜像。 仓库定义会有唯一的id,因此我们可以为仓库创建一个镜像引用,用来作为一个可替代的下载地址。镜像站点将首选服务器的仓库
  -->
  <mirrors>
    <!-- 
      指定要使用的仓库镜像站点来代替给定的仓库,镜像服务仓库有一个ID来对应镜像的mirrorOf元素。ID是用来继承和查找用的,在整个镜像集合中必须是唯一的。 
    -->
    <mirror>
      <!--镜像的唯一标识符,用来区分不同的mirror元素。 -->
      <id>mirrorId</id>
      <!--被镜像的服务器的id,比如:central,不能和id匹配。-->
      <mirrorOf>repositoryId</mirrorOf>
      <!-- 镜像名称 -->
      <name>Human Readable Name for this Mirror</name>
       <!--镜像的URL。构建系统会优先使用该URL,而不是默认的服务器URL。 -->
      <url>http://my.repository.com/repo/path</url>
    </mirror>
  </mirrors>

  <!-- 
      这是一个可以用许多方式激活的配置文件列表,在这里可以修改构建过程。settings.xml中提供的配置信息是用来提供本地特定机器路径和仓库位置的,
      这允许在本地环境中进行构建工作。例如,你有一个集成测试插件,假设为cactus,它需要知道Tomcat的安装地址,你可以在这提供一个变量,在构建过程中配置cactus插件时这个变量可以被间接引用。正如上面所提到的,可以通过许多方式来激活配置文件,一种方式是通过文档中(settings.xml)中的activeProfiles部分来激活,后面会进行讨论。另一种方式本质上是依赖系统属性的检测,通过匹配属性中的一个特定值或检测其是否存在。配置文件也可以通过JDK版本前缀激活,当在JDK 1.4.2_07版本上执行构建时,值1.4可以激活一个配置文件。最后,配置文件列表可以直接在命令行中指定。
      注意:对于在settings.xml文件中定义的配置文件,你只能指定工件仓库,插件仓库,自由形式的属性作为POM文件中插件配置的变量。
  -->
  <profiles>
    <!-- 
        指定构建过程的一系列介绍,通过上面描述的一种或多种机制来激活。对于继承,可以通过<activatedProfiles/>或命令行来激活配置文件,配置文件必须有一个唯一的ID。
        配置文件识别的最佳实践是在配置文件中使用一致的命名约定。例如'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett'等等。这样可以更直观的理解引入的配置文件要实现什么,尤其是在调试时只有一系列配置文件的id的情况下。
        这个配置文件例子使用JDK版本来触发激活,并提供JDK特定的仓库。

1. 设置apache及查占星关布置

# apache安装命令

$ sudo yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package httpd-2.4.6-45.el7.centos.4.x86_64 already installed and latest version
Nothing to do


# 查看apache文件的位置

$ sudo find / -name httpd
/run/httpd
/etc/logrotate.d/httpd
/etc/sysconfig/httpd
/etc/httpd
/var/log/httpd
/var/cache/httpd
/usr/sbin/httpd
/usr/lib64/httpd
/usr/share/httpd
/usr/include/httpd
/usr/libexec/initscripts/legacy-actions/httpd

Apache配置文件位于/etc/httpd/conf,首要的布局文件是/etc/httpd/conf/httpd.conf, apache相关的配置消息都得以在这里个文件中看见。

2. Maven安装

下载地址:https://maven.apache.org/download.cgi,解压之后找到Readme.txt依据表明安装就能够。也足以遵从Maven官方网站https://maven.apache.org/install.html安装。
作者是在Mac上接纳brew install maven指令安装的。

设置成功之后,能够运作mvn -v一声令下来查看:

# 查看java版本
$ java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

# 查看mvn版本,确认安装成功
$ mvn -v/-version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47 08:00)
Maven home: /usr/***/Cellar/maven/3.3.9/libexec
Java version: 1.8.0_91, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.6", arch: "x86_64", family: "mac"

注:Maven安装在此以前要确定保障您的系统中早已设置了JDK,可用java -version查看。

3. Maven目录结构

Maven是三个门类管理和营造自动化学工业具。Maven使用惯例优于配备的口径。Maven项指标目录结构如下:

目录 目的
${basedir} 存放 pom.xml和所有的子目录
${basedir}/src/main/java 项目的 java源代码
${basedir}/src/main/resources 项目的资源,比如说 property文件
${basedir}/src/test/java 项目的测试类,比如说 JUnit代码
${basedir}/src/test/resources 测试使用的资源
${basedir}/target 项目输出目录

maven项目编写翻译的classes文件会放在${basedir}/target/classes目录下,打包的公文种放在${basedir}/target目录下。

本文主要介绍scikit-learn中的交叉验证。

1. Maven介绍

Maven这么些单词来自于意第绪语(犹太语卡塔 尔(阿拉伯语:قطر‎,意为知识的积淀,最早在Jakata Turbine项目中用来简化创设进程。Maven首借使一个针对Java的种类管理和营造自动化学工业具。Maven首要处理软件构建的七个方面:1、描述软件是何等创设的,即项目构建;2、描述软件的信赖,即依赖处理。

4. Maven命令

测量试验mvn命令的档案的次序为Spring Boot项目,项目开创参照他事他说加以考查作者的小说:Spring Boot 2.0.0参照他事他说加以考查手册_中国和东瀛文对照_Part II_11-12

鉴于下载内容太多,没等它成功,小编撤销了,所以这里就没例子了。
