linux 安装 Elasticsearch5.6.x 详细步骤

linux安装Elasticsearch5.6.X详细步骤

第一步：环境

linux 系统 Java 1.8.0_151 elasticsearch-5.6.8

第二步：下载安装

1，下载JDK，安装JDK环境
- JDK的下载可以去官网上直接下载：http://www.oracle.com/technetwork/java/javase/downloads/index.html
- 直接将下载好的jdk-8u151-linux-x64.rpm 安装包 ;上传到自己创建好的JAVA文件下；cd 命令进入到JAVA文件下使用rpm 命令进行安装 rpm -ivh jdk-8u131-linux-x64.rpm 安装完成后执行 java -version 命令查看安装是否成功。
  配置环境变量，执行命令 vi /etc/profile；然后进入编辑模式，在文件的最后添加下面的配置，如图
  JAVA_HOME=/usr/javajdk1.8.0_151
  JRE_HOME=/usr/java/jdk1.8.0_151/jre
  CLASSPATH= $JAVA_HOME/lib:$ JRE_HOME/lib: $CLASSPATH PATH=$ JAVA_HOME/bin: $JRE_HOME/bin:$ PATH
  
  image.png
执行命令 source /etc/profile 使用环境变量生效
验证环境变量是否生效：echo $JAVA_HOME

2，下载安装ES
- 去官网直接下载，本人使用的是 5.6.8版本；因为版本的不同安装head插件的时候安装步骤不同；好像是从5.0 以后的版本安装head 插件的步骤就不一样了；下面会详细介绍。
  ES官网：https://www.elastic.co/
- 下载ES安装包elasticsearch-5.6.8.zip 在usr 目录下创建了es文件夹，将安装包上传到里面，解压 unzip elasticsearch-5.6.8.zip cd 进入 elasticsearch-5.6.8 文件里面。
- 创建ES用户和组（创建elsearch用户组及elsearch用户），因为使用root用户执行ES程序，将会出现错误；所以这里需要创建单独的用户去执行ES 文件；命令如下：
  命令一：groupadd elsearch
  命令二：useradd elsearch -g elsearch
  命令三：chown -R elsearch:elsearch
- 创建ES数据文件和日志文件，直接在root用户根目录一下创建就可以了
  执行命令：mkdir /data
  命令二：chown -R elsearch:elsearch /data/
  命令三：su - elsearch 切换用户
  命令四：mkdir -p es/data
  命令五：mkdir -p es/logs
  
  image.png
- 修改ES配置文件，使用cd命令进入到config 文件下，执行 vi elasticsearch.yml 命令，如图所示，本人没有配置集群，只是简单的配置了一下；详细说明可以参考官网；
- 执行ES文件，进入到bin 目录下执行 ./elasticsearch 命令就可以了，执行 ./elasticesrarch -d 是后台运行。
- 如果没有什么问题话，就可以安全生成了；然后执行curl 'http://自己配置的IP地址:9200/' 命令，就出现下面的结果

后台启动es命令：./bin/elasticsearch -d
可以看到es在后台启动了

第四步：问题

1，[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 意思是说你的进程不够用了
解决方案：切到root 用户：进入到security目录下的limits.conf；执行命令 vim /etc/security/limits.conf 在文件的末尾添加下面的参数值：

soft nofile 65536
hard nofile 131072
soft nproc 2048
hard nproc 4096
前面的*符号必须带上，然后重新启动就可以了。执行完成后可以使用命令 ulimit -n 查看进程数。

root@data-hadoop-112-15:~ $ ssh 192.168.129.94
Last login: Mon Dec  9 20:23:29 2019 from data-hadoop-112-15.bjrs.zybang.com
[root@owl-nginx-129-94 ~]# ulimit -n
655350

用户退出后重新登录生效

2，[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] 需要修改系统变量的最大值
解决方案：切换到root用户修改配置sysctl.conf 增加配置值： vm.max_map_count=655360
执行命令 sysctl -p 这样就可以了，然后重新启动ES服务就可以了。

第五步：安装head插件

1，下载head安装包，下载地址：https://github.com/mobz/elasticsearch-head/archive/master.zip 这是接从git 上下载下来，然后上传到虚拟机上的；由于head 插件不能放在elasticsearch-5.6.8 文件夹里，head 插件需要单独放，单独去执行；所以在elasticsearch-5.6.8 同级目录下解压了 head 插件；解压出来的文件名字，如图：

image.png
2，安装head 插件，需要node.js 的支持，所以，下面先安装一node.js
- 执行命令一：curl -sL https://rpm.nodesource.com/setup_8.x | bash -
- 命令二：yum install -y nodejs-----用brew来安装
  ➜ softeare brew install -y node.js
  Updating Homebrew...
  ==> Installing dependencies for node: icu4c
  ==> Installing node dependency: icu4c
  ==> Downloading https://homebrew.bintray.com/bottles/icu4c-61.1.high_sierra.bottle.tar.gz
  ######################################################################## 100.0%

image.png

执行完成后，可以使用命令 node -v 验证是否安装成功，同时npm 也安装成功了；执行命令 npm -v 也是可以验证的。

image.png

3，安装grunt ,由于head 插件的执行文件是有grunt 命令来执行的，所以这个命令必须安装
- npm install grunt --save-dev
  ---》brew ➜ softeare brew install grunt --save-dev
  Updating Homebrew...
  Warning: grunt-cli: this formula has no --save-dev option so it will be ignored!
  ==> Downloading https://homebrew.bintray.com/bottles/grunt-cli-1.2.0.high_sierra.bottle.tar.gz
  ######################################################################## 100.0%
  ==> Pouring grunt-cli-1.2.0.high_sierra.bottle.tar.gz
  🍺 /usr/local/Cellar/grunt-cli/1.2.0: 154 files, 251.3KB
  如果出现以下错误：
  
  image.png

则安装缺少的包：
参考:https://www.jianshu.com/p/a73d95030edb
npm install grunt-contrib-clean
npm install grunt-contrib-concat
npm install grunt-contrib-watch
npm install grunt-contrib-connect （安装了太久）
npm install grunt-contrib-copy
npm install grunt-contrib-jasmine
- 最后一个比较难安装，要联网到一个国外网站下载一个东西，而且貌似有个引擎要求的node比我这里的node版本高，会有一个warning，安装到Receiving...就杀了进程，杀掉之后再运行grunt可以看到一切都正常了，有条件的可以等待Receiving...后面的内容。
  
  image.png
- 命令二：npm install
  
  image.png
- 修改配置文件，cd 进入elasticsearch-head-master 文件夹下，执行命令vim Gruntfile.js文件：增加hostname属性，设置为*；如图：
  路径：elasticsearch-head-master/_site/app.js
  修改 localhost:9200 为实际 Elasticsearch 的地址
  修改前：this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
  修改后：
  this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://172.16.X.X:9200";

image.png

- 修改 vim _site/app.js 文件，修改head的连接地址，如图所示：

image.png

- 最后一个命令： grunt server &  执行完成后就OK了。

- 涉及到的问题，在网页上无法正常访问；查看防火墙是否关闭
  执行命令service iptables status 查看状态 ；直接将防火墙关闭就好了 执行命令service iptables stop。

image.png

- 最后执行的结果是这样的，我没有配置集群： 注意下面使用的端口号，不在是9200 了 而是head 插件中的 9100 了。

image.png

- 看到上面的出现的健康值了吗，说明的连接还是有问题的，解决方案是修改 cd 命令进入到elasticsearch-5.6.3 /config 文件中 vi elasticsearch.yml
     文件下添加 ：
    http.cors.enabled: true
    http.cors.allow-origin: "*"

然后重新执行ES ./elasticsearch 成功起来就可以了，执行结果就是这样的

- 未写入数据前：

head

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html

# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:

#
# Use a descriptive name for the node:
