, webmasters often use CPC alliances such as Baidu and Google (pay-as-you-go) to promote CPM alliances such as Yi and qilin (paid per thousand presentations ), CPS alliances such as Alimama (divided into payment based on sales results), CCAs, and other CPA alliances (paid based on guiding behaviors). Note the following when selecting the consortium: 1. if you select the above alliance, you must first apply for an ICP filing. the CPC alliance should pr

Modify Elasticsearch.yml, find Node.name, remove the previous #, modify it to node.name:node1 (take it yourself), but the name of each node must be different. Copy the elasticsearch-1.4.4.noarch.rpm to a different node and perform the 1~4 step. Other configuration, you can go into the Elasticsearch-1.4.4/bin directory to modify the elasticsearch.in.sh (mainly the JVM parameters), ELASTICSEARCH.YML also have many other parameters (cl

Brief introduction:Elk consists of three open source tools, Elasticsearch, Logstash and Kiabana:Elasticsearch is an open source distributed search engine, it features: distributed, 0 configuration, automatic discovery, Index auto-shard, index copy mechanism, RESTful style interface, multi-data source, automatic search load, etc.Logstash is a fully open source tool that collects, filters, and stores your logs for later use (for example, search).Kibana is also an open source and free tool that Kib
