一、下载
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.3.tar.gz
二、解压
1、解压tar xvf elasticsearch-6.1.3.tar.gz -C /usr/local/2、执行[root@zdhdbbsj local]# cd elasticsearch-6.1.3/[root@zdhdbbsj elasticsearch-6.1.3]# lsbin config data lib LICENSE.txt logs modules NOTICE.txt plugins README.textile[root@zdhdbbsj elasticsearch-6.1.3]# cd bin/[root@zdhdbbsj bin]# lselasticsearch elasticsearch-env.bat elasticsearch-plugin elasticsearch-service-mgr.exe elasticsearch-translog.batelasticsearch.bat elasticsearch-keystore elasticsearch-plugin.bat elasticsearch-service-x64.exeelasticsearch-env elasticsearch-keystore.bat elasticsearch-service.bat elasticsearch-translog[root@zdhdbbsj bin]# pwd/usr/local/elasticsearch-6.1.3/bin[root@zdhdbbsj bin]# ./elasticsearch[2018-02-05T12:03:43,449][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [] 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:125) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:112) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) ~[elasticsearch-cli-6.1.3.jar:6.1.3] at org.elasticsearch.cli.Command.main(Command.java:90) ~[elasticsearch-cli-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:85) ~[elasticsearch-6.1.3.jar:6.1.3]Caused by: java.lang.RuntimeException: can not run elasticsearch as root at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:104) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:171) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:322) ~[elasticsearch-6.1.3.jar:6.1.3] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:121) ~[elasticsearch-6.1.3.jar:6.1.3] ... 6 more[root@zdhdbbsj bin]#
3、报错不能已root运行，添加用户
[root@zdhdbbsj bin]# useradd elasticsearch[root@zdhdbbsj bin]# passwd elasticsearch更改用户 elasticsearch 的密码 。新的 密码：重新输入新的 密码：passwd： 所有的身份验证令牌已经成功更新。[root@zdhdbbsj bin]# chown -R elasticsearch.elasticsearch /usr/local/elasticsearch-6.1.3/
4、报错解决
ERROR: bootstrap checks failed
1、system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
原因：Centos6不支持SecComp，而ES5.4.1默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动。 详见 ：https://github.com/elastic/elasticsearch/issues/22899 解决方法：在elasticsearch.yml中新增配置bootstrap.system_call_filter，设为false，注意要在Memory下面: bootstrap.memory_lock: falsebootstrap.system_call_filter: false
2、max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
在文件/etc/security/limits.conf添加
* hard nofile 65536
* soft nofile 65536 3、max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]原因：无法创建本地线程问题,用户最大可创建线程数太小
解决方案：切换到root用户，进入limits.d目录下，修改90-nproc.conf 配置文件。 vi /etc/security/limits.d/90-nproc.conf 找到如下内容： * soft nproc 1024 #修改为 * soft nproc 20484、max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
虚拟内存太小下，修改文件/etc/sysctl.conf添加
vm.max_map_count=262144
sysctl -p 生效
以上问题解决后，es启动成功了，但又遇到了新的问题，本地机器无法访问虚拟机的服务，两个原因：
1）9200被限制为本机访问，需要在es的配置文件elasticsearch.yml中新增配置：
network.bind_host:9.1.6.140
2）关闭虚拟机防火墙
解决了这个两个问题后，本地能够顺利访问虚拟机的ES服务了。
