This article mainly explains "how to install and configure elasticserach+kibnan". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to install and configure elasticserach+kibnan".

Download elasticserach https://www.elastic.co/downloads/past-releases version elasticsearch-7.2.0-linux-x86_64.tar.gz

Server version: centos 7 virtual machine 2G memory

Java version "1.8.0,211"

Decompress tar-zxvf elasticsearch-7.2.0-linux-x86_64.tar.gz

Run in the bin directory. / elastisearch

Browsers run localhost:9200

The operation is successful.

Attention: 1: 00. Cannot run under the root account or there will be permission problems.

Open public network access: elasticsearch.yml under config

There is a problem:

ERROR: [3] bootstrap checks failed

: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]

: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Refer to the blog post https://blog.csdn.net/weixin_39800144/article/details/81162002

Switch to root user

Question [1]

Reason: the parameter max_map_count allows a process to have the maximum number in VMAs (virtual memory area). VMA is a contiguous virtual address space. When the process creates a memory image file, the address space of VMA increases. When max_map_count is reached, out of memory errors is returned.

/ / modify the following file to contain some kernel parameters

Vim / etc/sysctl.conf

/ / add the following configuration

Vm.max_map_count=655360

Save after adding, and then execute

Sysctl-p

Question [2]

Reason: the maximum number of file openings is too small. If this error occurs, switch to root user and modify limits.conf.

Vim / etc/security/limits.conf add

# End of file

Root soft nofile 65536

Root hard nofile 65536

* soft nofile 65536

* hard nofile 65536

Switch back to user restart:

ERROR: [1] bootstrap checks failed

: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

Solve

At this point, continue to edit the .config / elasticsearch.yml file and set the

# cluster.initial_master_nodes: ["node-1", "node-2"]

Change to cluster.initial_master_nodes: ["node-1"]

Successful restart of the public network connection is also successful

Install kibana

Download: https://www.elastic.co/downloads/past-releases

Try to choose the same version of Kibana as elasticserach.

Decompression

Tar-zxvf kibana-7.2.0-linux-x86_64.tar.gz

Run. / bin/kibana

Run successfully

Main: you can only run successfully when elasticserach is running, otherwise you will always be looking for startup.

Set public network startup:

Modify vim config/kibana.yml

Restart:

Access successful
