一、★★★★★★★单机版安装及环境配置★★★★★★★ 安装环境 CentOS release 6.7 (Final) 1、因Elasticsearch是基于Java写的,所以它的运行环境中需要java的支持,在Linux下执行命令: java -version,检查Jar包是否安装 安装java版本至少是1.8以上 2、首先准备下载Elasticsearch5.5.0 安装包 wget https://artifacts.elastic.co/d ... earch 3、下载到/usr/openv 目录下,解压 tar -zxvf  elasticsearch-5.5.0.tar.gz 4、因为Elasticsearch5.0之后,不能使用root账户启动,我们先创建一个esuser组和账户 useradd  esuser -g esuser -p esuser 5.更改文件夹权限 chown -R esuser:esuser /usr/openv/elasticsearch-5.5.0 6、启动elasticsearch: /usr/openv/elasticsearch-5.5.0/bin su esuser ./elasticsearch    (前台启动) 这时候我们看见下面的提示,说明就成功了:     1.    [elasticsearch@vmlnx-sma bin]$ ./elasticsearch   2.    [2017-03-02T21:43:21,185][INFO ][o.e.n.Node               ] [] initializing ...   3.    [2017-03-02T21:43:21,264][INFO ][o.e.e.NodeEnvironment    ] [uY3prpy] using [1] data paths, mounts [[/ (/dev/mapper/VolGroup-lv_root)]], net usable_space [43.5gb], net total_space [54.6gb], spins?

    "number": "1.4.0",       "lucene_version": "4.10"    },    "tagline": "You Know, for Search" } 说明安装成功。 但是我们希望能够使用ip访问,那么还需要设置相关内容 跳转到Elasticsearch的config配置文件下,使用vim打开elasticsearch.yml,找到里面的"network.host",将其改为本机IP,保存。 cd elasticsearch/config/ vim elasticsearch.yml 重启ElasticSearch,然后使用http://192.168.37.137:9200/访问。

如果是前台启动,直接Ctrl+Z或者直接关掉命令行窗口,则服务器立即停止。 如果是通过后台启动的ES服务,则需要用如下命令停止服务器: 也可以直接在Window系统的服务列表中找到安装的服务,然后右键停止。 另外,还可以通过curl工具来关掉整个集群或者集群中的指定节点,命令如下: 关掉集群:curl -XPOST http://localhost:9200/-cluster/nodes/_shutdown。 关掉指定的节点,节点标识符为jMJhGirhSRa9Iw2fQtjJ5A:curl -XPOST http://localhost:9200/_cluster ... tdown。 重启ES服务器 如果是想再次重启已经启动的ES服务,可以在Window系统的服务列表中找到安装的服务,然后右键重新启动即可。
