2.ElasticSearch 安装
下载
cd /opt/download
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.4.tar.gz
wget https://artifacts.elastic.co/downloads/kibana/kibana-6.5.4-linux-x86_64.tar.gz
解压
tar -zxvf elasticsearch-6.5.4.tar.gz -C ../softwares
tar -zxvf kibana-6.5.4-linux-x86_64.tar.gz -C ../softwares
配置
cd ../softwares/elasticsearch-6.5.4/config
vim elasticsearch.yml

------------------------------------
# 让参数生效
sudo sysctl -p
启动es
官网推荐启动方式
# 第一种：后台启动
./bin/elasticsearch -d
# 第二种：后台启动，并将进程号赋值给当前shell全局变量pid，使用 kill `cat pid` 可以删除进程(只能在shell命令行使用，脚本不好使)
./bin/elasticsearch -d -p pid
# 第三种：手动传参，定义集群和节点名称
./bin/elasticsearch -d -Ecluster.name=clustername -Enode.name=nodename
配置环境变量
sudo vim /etc/profile
------------------------------------
export ES_HOME=/opt/softwares/elasticsearch-6.5.4
export PATH=$ES_HOME/bin:$PATH
alias es_status="curl http://localhost:9200/"
alias es_on="$ES_HOME/bin/elasticsearch -d"
alias es_off="ps -ef | grep 'org.elasticsearch.bootstrap.Elasticsearch' | grep -v grep | awk -F ' ' '{print $2}'| xargs kill"
------------------------------------
./bin/elasticsearch -d 启动
curl http://localhost:9200/
{
