1：下载和解压： wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.3.2.tar.gz 2：配置config/elasticsearch.yml network.host: 10.99.32.16 http.port: 9200 path.logs: /root/elasticsearch/log path.data: /root/elasticsearch/data node.name: node-1 cluster.name: mycluster discovery.zen.ping.unicast.hosts: ["10.99.32.16", "10.99.32.17", "10.99.32.18"] discovery.zen.minimum_master_nodes: 2 bootstrap.memory_lock: true 3：配置config/jvm.options 4：配置一些系统内核参数：
can not run elasticsearch as root： 不能使用root用户进行操作，需要创建一个用户，并把原来的目录的拥有者更改为该用户 adduser myuser passwd myuser chown -R myuser /mypath
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 修改/etc/security/limits.conf 添加：elastic hard nofile 65536
max file size [67107840] for user [elastic] is too low, increase to [unlimited] 修改/etc/security/limits.conf elastic soft fsize unlimited
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] 解决：sysctl -w vm.max_map_count=262144
5：运行： bin/elasticsearch 后台运行：bin/elasticsearch -d -p pidFile 会生成一个pidFile文件，记录pid 随系统启动： sudo /bin/systemctl daemon-reload sudo /bin/systemctl enable elasticsearch.service
