Centos7.4下安装ElasticSearch

Set up Elasticsearch

 

This section includes information on how to setup Elasticsearch and get it running, including:

  • Downloading
  • Installing
  • Starting
  • Configuring

Supported platforms

The matrix of officially supported operating systems and JVMs is available here: Support Matrix. Elasticsearch is tested on the listed platforms, but it is possible that it will work on other platforms too.

Java (JVM) Version

Elasticsearch is built using Java, and includes a bundled version of OpenJDK from the JDK maintainers (GPLv2+CE) within each distribution. The bundled JVM is the recommended JVM and is located within the jdk directory of the Elasticsearch home directory.

To use your own version of Java, set the JAVA_HOME environment variable. If you must use a version of Java that is different from the bundled JVM, we recommend using a supported LTS version of Java. Elasticsearch will refuse to start if a known-bad version of Java is used. The bundled JVM directory may be removed when using your own JVM.

备注：https://www.elastic.co/guide/en/elasticsearch/reference/7.4/setup.html

Installing the Elastic Stack

When installing the Elastic Stack, you must use the same version across the entire stack. For example, if you are using Elasticsearch 7.4.0, you install Beats 7.4.0, APM Server 7.4.0, Elasticsearch Hadoop 7.4.0, Kibana 7.4.0, and Logstash 7.4.0.

If you’re upgrading an existing installation, see Upgrading the Elastic Stack for information about how to ensure compatibility with 7.4.0.

Installation Order

Install the Elastic Stack products you want to use in the following order:

  1. Elasticsearch (install instructions)
  2. Kibana (install)
  3. Logstash (install)
  4. Beats (install instructions)
  5. APM Server (install instructions)
  6. Elasticsearch Hadoop (install instructions)

Installing in this order ensures that the components each product depends on are in place.

Install Elasticsearch with RPM

The RPM for Elasticsearch can be downloaded from our website or from our RPM repository. It can be used to install Elasticsearch on any RPM-based system such as OpenSuSE, SLES, Centos, Red Hat, and Oracle Enterprise.

Import the Elasticsearch PGP Key

We sign all of our packages with the Elasticsearch Signing Key (PGP key D88E42B4, available from https://pgp.mit.edu) with fingerprint:

4609 5ACC 8548 582C 1A26 99A9 D27D 666C D88E 42B4

Download and install the public signing key:

[root@LogServer zhangxm]# rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

Installing from the RPM repository

Create a file called elasticsearch.repo in the /etc/yum.repos.d/ directory for RedHat based distributions, or in the /etc/zypp/repos.d/ directory for OpenSuSE based distributions, containing:

 

[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

 

自己在虚拟服务器上创建的文件名为 elk.repo

And your repository is ready for use. You can now install Elasticsearch with one of the following commands:

sudo yum install elasticsearch

Download and install the RPM manually

The RPM for Elasticsearch v7.4.0 can be downloaded from the website and installed as follows:

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.0-x86_64.rpm
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.0-x86_64.rpm.sha512
shasum -a 512 -c elasticsearch-7.4.0-x86_64.rpm.sha512 
sudo rpm --install elasticsearch-7.4.0-x86_64.rpm

NOTE：Compares the SHA of the downloaded RPM and the published checksum, which should output elasticsearch-{version}-x86_64.rpm: OK.

上述执行过程中遇到两个错误：

错误1：-bash: shasum: command not found

解决方案：在CentOS上，“shasum”被称为“sha1sum”，运行下面命令修复此问题

　　　  ln -s /usr/bin/sha1sum /usr/bin/shasum

错误2：sha1sum: invalid option -- 'a'

解决方案：yum install -y perl-Digest-SHA

 

SysV init vs systemd

Elasticsearch is not started automatically after installation. How to start and stop Elasticsearch depends on whether your system uses SysV init or systemd (used by newer distributions). You can tell which is being used by running this command:

ps -p 1

自己执行命令如下：

1 [root@LogServer elasticsearch]# ps -p 1
2    PID TTY          TIME CMD
3      1 ?        00:00:45 systemd
View Code

显然用的是systemd

Running Elasticsearch with systemd

To configure Elasticsearch to start automatically when the system boots up, run the following commands:

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

Elasticsearch can be started and stopped as follows:

sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service

These commands provide no feedback as to whether Elasticsearch was started successfully or not. Instead, this information will be written in the log files located in /var/log/elasticsearch/.

 

自己执行命令如下：

 1 [root@LogServer elasticsearch]# sudo systemctl start elasticsearch.service
 2 [root@LogServer elasticsearch]# sudo systemctl status elasticsearch.service

查看Status时发现有Warning：OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.（即cms 垃圾收集器在 jdk9 就开始被标注为 @deprecated）

解决方案：

修改/etc/elasticsearch/jvm.options文件如下：

## GC configuration
#-XX:+UseConcMarkSweepGC      ##注释掉该行配置
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
## G1GC Configuration
# NOTE: G1GC is only supported on JDK version 10 or later.
# To use G1GC uncomment the lines below.

10-:-XX:+UseG1GC      ##JDK11支持的垃圾回收器
# 10-:-XX:G1ReservePercent=25
# 10-:-XX:InitiatingHeapOccupancyPercent=30
 
备注：jvm.options文件语法可参考https://www.elastic.co/guide/en/elasticsearch/reference/7.4/jvm-options.html

修改/etc/elasticsearch/elasticsearch.yml配置文件后重启

1 [root@LogServer elasticsearch]# egrep -v "#|^$" /etc/elasticsearch/elasticsearch.yml
2 node.name: node-1
3 path.data: /var/lib/elasticsearch
4 path.logs: /var/log/elasticsearch
5 network.host: 0.0.0.0
6 http.port: 9200
7 cluster.initial_master_nodes: ["node-1"]

 

Checking that Elasticsearch is running

You can test that your Elasticsearch node is running by sending an HTTP request to port 9200 on localhost:

which should give you a response something like this:

{
  "name" : "Cp8oag6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
  "version" : {
    "number" : "7.4.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "f27399d",
    "build_date" : "2016-03-30T09:51:41.449Z",
    "build_snapshot" : false,
    "lucene_version" : "8.2.0",
    "minimum_wire_compatibility_version" : "1.2.3",
    "minimum_index_compatibility_version" : "1.2.3"
  },
  "tagline" : "You Know, for Search"
}

用curl命令检查 

 1 [root@LogServer zhangxm]# curl -iv localhost:9200
 2 * About to connect() to localhost port 9200 (#0)
 3 *   Trying ::1...
 4 * Connected to localhost (::1) port 9200 (#0)

27     "build_date" : "2019-09-27T08:36:48.569419Z",
28     "build_snapshot" : false,
29     "lucene_version" : "8.2.0",
30     "minimum_wire_compatibility_version" : "6.8.0",
31     "minimum_index_compatibility_version" : "6.0.0-beta1"
