Set a different # address here to expose this node on the network: # #network.host: 192.168.0.1 #network.host: 0.0.0.0 network.host: 192.168.88.108 #network.host: 0.0.0.0 # # By default Elasticsearch listens for HTTP traffic on the first free port it # finds starting at 9200. Set a specific HTTP port here: # http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # #discovery.seed_hosts: ["host1", "host2"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: ["node-1"] #cluster.initial_master_nodes: ["node-1", "node-2"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true #network.host: 0.0.0.0 #http.cors.enabled: true #http.cors.allow-origin: "* apt 也要记得看这个配置 参考 tar xvf elasticsearch-6.4.3.tar.gz mv elasticsearch-6.4.3/ /usr/local/elasticsearch/ vim elasticsearch.yml 修改配置文件，在最下面加入如下几行 network.host: 0.0.0.0 http.port: 9200 http.cors.enabled: true http.cors.allow-origin: "*" 注意，root用户是不能直接启动elasticsearch的，需要新建用户，然后切换用户去启动elasticsearch，如下： 创建elsearch用户组及elsearch用户 groupadd elsearch useradd elsearch -g elsearch -p elasticsearch 更改elasticsearch文件夹及内部文件的所属用户及组为elsearch:elsearch chown -R elsearch:elsearch 切换到elsearch用户再启动 su elsearch cd elasticsearch/bin bash elasticsearch & systemctl stop firewalld systemctl disable firewalld 配置管理 Elasticsearch一般不需额外配置，但是为了提高Elasticsearch性能可以通过elasticsearch.yml文件修改配置参数。当然，也可以根据用户系统配置降低配置参数，如jvm.heapsize。Elasticsearch默认占用2G内存，对于系统配置较低的服务器，很可能带来负载过大的问题，因此需要适当减少jvm.heapsize
Elasticsearch7.7修改network.host IP地址 start启动失败

Kibana
install
#kibana主要是搜索elasticsearch的数据，并进行数据可视化的展现，新版使用nodejs * kibana配置启动 [root@localhost kibana]# pwd /usr/local/kibana vim config/kibana.yml server.port: 5601 server.host: "0.0.0.0" elasticsearch.url: "http://localhost:9200" kibana.index: ".kibana" cd bin/ sh kibana & 启动kibana 启动完毕，可以浏览器输入url: 服务器外网ip:5601 查看是否成功启动： http://192.168.88.52:5601/app/kibana#/home?_g=() 配置******** Kibana配置可以通过命令行参数或配置文件kibana.yml。Kibana应用的默认地址为localhost，无法从远程访问Kibana，因此，用户需要修改配置文件的server.host属性
配置nginx，为kibana配置反向代理
server{
listen 80;
server_name elk.com;
location / {
proxy_set_header Host $host;
proxy_pass http://localhost:5601;
}
Logstash
#为了测试 这和ng 和logstash 在同一台机器上
mv logstash-6.4.2/ /usr/local/logstash/
cd /usr/local/logstash/bin/
#用这个nginx的
cat /usr/local/logstash/config/nginx.conf
input {
file {
path => "/var/log/nginx/access.log"
type => "nginx"
codec => "json"
start_position => "beginning"
}
}
filter {
geoip {
fields => ["city_name", "country_name", "latitude", "longitude", "region_name","region_code"]
source => "client"
}
}
output {
if [type] == "nginx" {
elasticsearch {
hosts => ["127.0.0.1:9200"]
index => "nelson-nginx-%{+YYYY.MM.dd}"
}
stdout {}
}
}
# 是Elasticsearch 的ip哦 千万不能写错啦 线上的情况一般是l 和ek 不在同一个机器
# hosts => ["127.0.0.1:9200"]
./bin/logstash -f ./config/nginx.conf
访问nginx 就会 在控制台看到如下输出
"@timestamp" => 2019-05-31T08:26:26.000Z,
"domian" => "192.168.88.52",

查看
你的 kibana 地址 ,这个 这次变了

attention 注意 官方 教程

或者参考这个 3.2 yml 好有意思

ELK 之三：Kibana 使用与Tomcat、Nginx 日志格式处理
安全
https://www.elastic.co/guide/en/elasticsearch/reference/7.12/security-minimal-setup.html
nginx代理
1.安装nginx 2.安装Apache密码生产工具 httpd-tools 3.生成密码文件 4.配置Nginx 5.修改 kibna配置文件 6.重启kibna,Nginx 查看登录界面
x-pack
官方提供x-pack组件，进行安全防护，报表，集群实时监控。 只安装x-pack中的Shield 只是对 kibna放在公网 对kibna进行登录验证的话，可以用nginx 代理功能 1.nginx代理 2.使用Shield 3.x-pack组件
