docker 安裝elasticsearch

請參考官方docker-compose檔案https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

在裝之前先修改sysctl.conf檔案

echo 'vm.max_map_count=262144' > /etc/sysctl.conf
sysctl -p
echo "root soft nofile 65536" >> /etc/security/limits.conf
echo "root hard nofile 65536" >> /etc/security/limits.conf
echo 
 
"* soft nofile 65536" >> /etc/security/limits.conf
echo "* hard nofile 65536" >> /etc/security/limits.conf
source /etc/security/limits.conf

1）docker安裝單節點elasticsearch

docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.9.0

2）docker安裝三節點elasticsearch

mkdir /usr/local/elasticsearch

下面的命令直接把程式碼寫到docker-compose.yml

之後cd/usr/local/elasticsearch

docker-compose up -d

#看看是否工作

curl -X GET "localhost:9200/_cat/nodes?v&pretty"

還是推薦去看看官方的連結
