#安装elasticsearch-5.3.1.tar.gz(单节点安装)
tar xf elasticsearch-5.3.1.tar.gz
cd elasticsearch-5.3.1
vim config/elasticsearch.yml #修改配置文件
path.data: /data/elas/data #数据目录
path.logs: /data/elas/logs
network.host: 0.0.0.0 #允许哪个IP访问
http.port: 9200
修改系统参数以确保系统有足够资源启动ES
设置内核参数
vim /etc/sysctl.conf
# 增加以下参数
vm.max_map_count=655360
执行以下命令，确保生效配置生效：
sysctl -p
设置资源参数
vim /etc/security/limits.conf
# 修改
* soft nofile 65536
* hard nofile 131072
* soft nproc 65536
* hard nproc 131072
设置用户资源参数
vim /etc/security/limits.d/20-nproc.conf
elk soft nproc 65536 # 设置elk用户参数
添加启动用户，设置权限
启动ElasticSearch5版本要非root用户，需要新建一个用户来启动ElasticSearch
useradd elk
mkdir -pv /data/elas/{data,logs} # 创建数据和日志目录
chown -R elk:elk /data/elas/ # 修改文件所有者
chown -R elk:elk /usr/local/elasticsearch-5.3.1/
su elk
bin/elasticsearch -d #-d 为保持后台运行
curl localhost:9200 来检查ES是否启动成功
#安装kibana-5.3.1-linux-x86_64.tar.gz
tar xf kibana-5.3.1-linux-x86_64.tar.gz

server.port: 5601 #开启默认端口5601
server.host: “192.168.182.100” #站点地址,必须是IP
elasticsearch.url: http://192.168.182.100:9200 #指向>elasticsearch服务的ip地址,必须是IP
