最近在折腾springCloud,所以第一步就是安装部署Eureka，在网上找了几篇文章折腾了半天，终于搞定，怕以后忘记继续踩坑，所以把这两篇纪录下来。

Netflix开源的Eureka 是使用Gradle 构建的，所以我们也使用Gradle来编译它
所需环境
Eclipse , Gradle , Tomcat ,git 这些插件如果己经安装可直接跳过到Eureka 服务器的步骤
Eclispe
下载官网 https://www.eclipse.org/ 下载下来安装即可，过程省略
本人使用的是：Version: Neon Release (4.6.0) 版本
Gradle
1、下载Gradle https://services.gradle.org/distributions/gradle-2.14-all.zip
2、添加环境变量GRADLE_HOME，添加值为 C:\gradle-2.9-bin\gradle-2.9;（注意根据自己的实际安装路径修改）
3、PATH环境变量中添加%GRADLE_HOME%/bin；
4、验证，命令行中输入gradle -v，查看是否配置正确，正确会输出gradle的版本信息；
Gradle eclipse 插件：
1.eclipse中依次打开“Help”–》“Eclipse Marketplace”,在搜索栏中输入“buildship”进行搜索；
2.点击install，等待安装完成，按照提示重启eclipse即可。
3.安装成功后，可以在Window–>Show View–>Others…中和File–>New–> Other…中看到增加的Gradle选项。
4、设置Eclipse 中Gradle User Home 为环境变量中的路径。
Git
本人使用Eclipse 自带的Git 插件，所以无需再安装，如果不使用Eclispe的也可以自己下载安装,过程省略
Eureka 服务器
从 github 获取 Eureka 源码：
1、eclipse ->import
2、
3、 输入: https://github.com/Netflix/eureka.git
按下一步完成源码下载
4、将Eureka 以Gradle 方式导入eclipse
5、指定git下载eureka源码的目录
6、导入完成后如下图所示
7、 正式编译 Eureka
安装过Gradle eclipse 插件就会显示 Gradle Tasks ， 如果没显示就在window--->show view -->other中就面版显示出来
右键运行war 打包， 打包可能会出现 nebula.netflixoss 插件找不到，修改如下三处就能下载该插件
还有可能出现其它插件找不到，修改如下
再次运行war 打包，这时应该可以打包成功
按照源码编译方式打包并没有将 jsp ,css 等打包进去，部署完后访问http://localhost:8080/eureka 可能无法看到eureka 界面，
所以还需要修改eureka-server 这个工程，将resources 也跟eureka-server 一起打包
Eureka 部署到Tomcat
将war 包的名称修改一下 如下图，放入 tomcat webapps 下，
启动tomcat , 启动过程中有可能报异常 Cannot execute request on any known server 这个是正常的,启动的时候会去找其他的 server，
找不到，过一会就自己启动了,等待五分钟左右，访问 http://localhost:8080/eureka
说明 Eureka Server 部署成功
1. 查看 Linux 相关信息 版本查看# cat /etc/issueCentOS release 6.5 (Final) 位数查看# getconf LONG_BIT64 第 2 - 4 步是 Eureka Server war 包的构建，如果你嫌自己构建麻烦可以去 http://mvnrepository.com/artifact/com.netflix.eureka/eureka-server 下载一个，比如作者下载的是 eureka-server-1.1.134.war，然后跳过 2 - 4 步直接进入第 5 步。 2. 安装 git# yum install git 查看安装结果# git --versiongit version 1.7.1# which git/usr/bin/git 3. 安装 gradle 安装 Gradle 要求实现好了 JDK(关于 Linux 上 JDK 的安装参考《如何在 64 位 linux 机器上安装 jdk1.6？》)。Gradle 自带 Groovy 库，已有安装好的 Groovy 将被 Gradle 忽视。 然后去官网下载 gradle-1.12-bin.zip(大小 41 MB)到 /root/kdf 目录：http://www.gradle.org/downloads。# unzip gradle-1.12-bin.zip# cp -r ~/kdf/gradle-1.12 /usr/local/gradle-1.12# vi /etc/profile 在末尾添加以下几行：[plain] view plain copy
print?
在CODE上查看代码片
派生到我的代码片
export GRADLE_HOME=/usr/local/gradle-1.12
export PATH=$PATH:$GRADLE_HOME/bin
保存退出，然后执行**# source /etc/profile** 验证环境变量：**# echo $PATH**/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/java/jdk1.7.0_60/bin:/usr/local/gradle-1.12/bin 验证 gradle 是否安装成功：**# gradle -v**------------------------------------------------------------Gradle 1.12------------------------------------------------------------Build time: 2014-04-29 09:24:31 UTCBuild number: noneRevision: a831fa866d46cbee94e61a09af15f9dd95987421Groovy: 1.8.6Ant: Apache Ant(TM) version 1.9.3 compiled on December 23 2013Ivy: 2.2.0JVM: 1.7.0_60 (Oracle Corporation 24.60-b09)OS: Linux 2.6.32-431.el6.x86_64 amd64 输出结果中显示了我们安装的 Gradle 的版本以及本地环境配置信息，证明安装成功。 **4. 构建 Eureka 服务器** 从 github 获取 Eureka 源码：**# git clone https://github.com/Netflix/eureka.git** 在存放源码的路径下执行以下命令以构建 Eureka 服务器：**# cd eureka/# ./gradlew clean build** 成功后在 ./eureka-server/build/libs/ 目录下找到 war 包。 **5. 安装 tomcat** 安装 Eureka 服务器要求事先安装好了 Tomcat。去 [http://tomcat.apache.org/](http://tomcat.apache.org/) 下载你想要的版本，比如作者下载的是 [apache-tomcat-6.0.41.tar.gz](http://mirrors.hust.edu.cn/apache/tomcat/tomcat-6/v6.0.41/bin/apache-tomcat-6.0.41.tar.gz)，大小 7 MB。**# tar zxvf apache-tomcat-6.0.41.tar.gz# cp -r apache-tomcat-6.0.41 /usr/local/tomcat# /usr/local/tomcat/bin/startup.sh** 其他电脑客户端访问 http://serverIP:8080，如果小猫没出来，在服务器执行**# curl http://localhost:8080** 有 Tomcat 管理界面 HTML 文字输出，说明没有开放服务器防火墙 8080 端口，开放该端口或者直接关掉防火墙。 **6. 部署 Eureka server# /usr/local/tomcat/bin/shutdown.sh# cp eureka-server-1.1.134.war /usr/local/tomcat/webapps/eureka.war# /usr/local/tomcat/bin/startup.sh** Tomcat 启动以后，其他电脑客户端访问 http://serverIP:8080/eureka，404。查看 /usr/local/tomcat/logs/catalina.out，发现有警告信息：2014-07-03 09:47:00,614 WARN com.netflix.config.util.ConfigurationUtils:165 [main] [loadFromPropertiesFile] Unable to
