Elasticsearch_安装

安装

单机安装

docker容器安装Elasticsearch7

1.创建目录 并授权

mkdir -p /usr/local/elasticsearch/config 
mkdir  -p /usr/local/elasticsearch/data
mkdir  -p /usr/local/elasticsearch/plugins
echo "http.host: 0.0.0.0" >> /usr/local/elasticsearch/config/elasticsearch.yml

chmod 777 -R /usr/local/elasticsearch

2.启动运行

  docker run -d --name  elasticsearch7 -p 9200:9200 -p 9300:9300 \
  -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx128m" \
  -v /usr/local/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
  -v /usr/local/elasticsearch/data:/usr/share/elasticsearch/data \
  -v /usr/local/elasticsearch/plugins:/usr/share/elasticsearch/plugins elasticsearch:7.10.1

参数说明

-e "discovery.type=single-node" 设置为单节点
-e ES_JAVA_OPTS="-Xms128m -Xmx128m" 设置ES的初始内存和最大内存，否则过大启动不了ES

3.发现外网访问不到，只能 127.0.0.1:9200 访问，设置网络

 vi /etc/sysctl.conf

发现 net.ipv4.ip_forward=0，应改为 net.ipv4.ip_forward=1，并执行使之生效

systemctl restart network
