Elasticsearch起步之安装(一)

elasticsearch下载

• 下载安装包并保存至 /tmp 目录下

wget -P /tmp https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.1-linux-x86_64.tar.gz

• 创建文件夹opt/soft/elasticsearch

sudo mkdir -p /opt/soft/elasticsearch

• 将下载好的压缩包移至目标目录并解压

mv /tmp/elasticsearch-7.1.1-linux-x86_64.tar.gz  /opt/soft/elasticsearch
tar -xzf elasticsearch-7.1.1-linux-x86_64.tar.gz
mv elasticsearch-7.1.1-linux-x86_64.tar.gz

• 创建一个软链接
  开发环境如JDK、MAVEN等统一链接至/usr/local目录下方便以后查找

sudo ln -s /opt/soft/elasticsearch/elasticsearch-7.1.1 /usr/local/elasticsearch

启动

配置

配置文件目录：/usr/local/elasticsearch/config/elasticsearch.yml

#任何IP都可访问
network.host: 0.0.0.0
discovery.seed_hosts: ["127.0.0.1"]

启动

启动命令如下：

#进入es安装目录
cd /usr/local/elasticsearch/bin
#普通执行
./elasticsearch
#后台执行
./elasticsearch -d

验证ES是否启动成功，浏览器输入：
