一、下载包
官网：https://www.elastic.co/downloads/elasticsearch
下载：wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.1.tar.gz
解压：tar -zxvf elasticsearch-6.5.1.tar.gz
改变所有者：给elasticsearch专门建立一个用户es，将elasticsearch所有者分配给es，chown -R es:es elasticsearch-6.5.1/
二、配置
修改network.host和http.port
vi config/elasticsearch.yml
# ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # #network.host: 192.168.0.1 network.host: 192.168.31.10 # # Set a custom port for HTTP: # #http.port: 9200 http.port: 9200
注意yml配置文件中key: value格式冒号后面要跟一个空格。
否则程序会报如下错误：
Exception in thread "main" 2018-11-29 22:49:13,680 main ERROR No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property ‘log4j2.debug‘ to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2 SettingsException[Failed to load settings from [elasticsearch.yml]]; nested: ParsingException[Failed to parse object: expecting token of type [START_OBJECT] but found [VALUE_STRING]]; at org.elasticsearch.common.settings.Settings$Builder.loadFromStream(Settings.java:1216) at org.elasticsearch.common.settings.Settings$Builder.loadFromPath(Settings.java:1189) at org.elasticsearch.node.InternalSettingsPreparer.prepareEnvironment(InternalSettingsPreparer.java:100) at org.elasticsearch.cli.EnvironmentAwareCommand.createEnv(EnvironmentAwareCommand.java:95) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:93) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:86) Caused by: ParsingException[Failed to parse object: expecting token of type [START_OBJECT] but found [VALUE_STRING]] at org.elasticsearch.common.xcontent.XContentParserUtils.ensureExpectedToken(XContentParserUtils.java:78) at org.elasticsearch.common.settings.Settings.fromXContent(Settings.java:696) at org.elasticsearch.common.settings.Settings.access$500(Settings.java:84) at org.elasticsearch.common.settings.Settings$Builder.loadFromStream(Settings.java:1212) ... 8 more
三、修改linux核心配置
vm.max_map_count=262144
这里的修改方式是在/etc/sysctl.d/目录下新建一个配置文件vm.max_map_count.conf
vi /etc/sysctl.d/vm.max_map_count.conf
里面输入：vm.max_map_count=262144
保存退出后，用sysctl -p vm.max_map_count.conf 生效配置。
用sysctl -a|grep vm.max_map_count检查一下，如果有问题重启看看。
四、配置打开文件数
vi /etc/security/limits.conf
文件尾部添加： #soft是一个警告值，而hard则是一个真正意义的阀值，超过就会报错 * hard nofile 65536 #任何一个用户可以打开的最大的文件描述符数量，默认1024，这里的数值会限制tcp连接 * soft nofile 65536 #任何一个用户可以打开的最大进程数 * soft nproc 2048 * hard nproc 4096 # End of file
五、启动elasticsearch
bin/elasticsearch
验证：
[root@bigdata-senior01 elasticsearch-6.5.1]# curl http://192.168.31.10:9200 { "name" : "Sa5md_z", "cluster_name" : "elasticsearch", "cluster_uuid" : "0be4QBGhQQu2pf9MnGjbkA", "version" : { "number" : "6.5.1", "build_flavor" : "default", "build_type" : "tar", "build_hash" : "8c58350", "build_date" : "2018-11-16T02:22:42.182257Z", "build_snapshot" : false, "lucene_version" : "7.5.0", "minimum_wire_compatibility_version" : "5.6.0", "minimum_index_compatibility_version" : "5.0.0" }, "tagline" : "You Know, for Search" }
