Elasticsearch起步之安裝(一)

elasticsearch下載

• 下載安裝包並保存至 /tmp 目錄下

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

• 創建文件夾opt/soft/elasticsearch

sudo mkdir -p /opt/soft/elasticsearch

• 將下載好的壓縮包移至目標目錄並解壓

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

• 創建一個軟鏈接
  開發環境如JDK、MAVEN等統一鏈接至/usr/local目錄下方便以後查找

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

啓動

配置

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