选择6.8.8版本
https://www.elastic.co/guide/en/elasticsearch/reference/6.8/zip-targz.html
官方文档，安装说明
1、先安装java
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
选择【Linux x64 RPM Package】
[root@host101 ~]# rpm -ivh jdk-8u251-linux-x64.rpm warning: jdk-8u251-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY Preparing... ################################# [100%] Updating / installing... 1:jdk1.8-2000:1.8.0_251-fcs ################################# [100%] Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... [root@host101 ~]#
2、下载elasticsearch软件，解压到/usr/locl目录下
[root@host101 ~]# tar xvf elasticsearch-6.8.8.tar.gz -C /usr/local/
[root@host101 ~]# cd /usr/local/
[root@host101 local]# mv elasticsearch-6.8.8/ elasticsearch
3、运行elasticsearch,开启报错之旅
3.1报错：
不能以root用户运行，
[root@host101 elasticsearch]# bin/elasticsearch OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N [2020-06-08T07:53:35,386][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [unknown] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:163) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:150) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) ~[elasticsearch-cli-6.8.8.jar:6.8.8] at org.elasticsearch.cli.Command.main(Command.java:90) ~[elasticsearch-cli-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:116) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:93) ~[elasticsearch-6.8.8.jar:6.8.8] Caused by: java.lang.RuntimeException: can not run elasticsearch as root at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:103) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:170) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:333) ~[elasticsearch-6.8.8.jar:6.8.8] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:159) ~[elasticsearch-6.8.8.jar:6.8.8] ... 6 more
解决方法：
添加其它用户，我新加了一个es用户，将elasticsearch目录授予es用户,启动成功。
[root@host101 elasticsearch]# useradd es
[root@host101 elasticsearch]# chown -R es:es /usr/local/elasticsearch/

但默认监控的是127.0.0.1端口，其它IP访问不到ES数据库，需要修改为本机Ip 192.168.150.101
[root@host101 config]# cd /usr/local/elasticsearch/config/ [root@host101 config]# vi elasticsearch.yml 修改这个参数 network.host: 192.168.150.101 保存！

需要使用root用户去修改
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
[root@host101 config]# vi /etc/security/limits.conf
加入
* soft nofile 65536
* hard nofile 65536
保存！
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
[root@host101 config]# vi /etc/sysctl.conf 加入 vm.max_map_count=262144 保存！ [root@host101 config]# sysctl -p vm.max_map_count = 262144 [root@host101 config]#
