安装前的检查

1. 安装 Elasticsearch 之前，你需要先安装一个较新的版本的 Java，最好的选择是，你可以从 www.java.com 获得官方提供的最新版本的 Java。

2. 安装JDK

   sudo yum install java-1.8.0-openjdk.x86_64

3. 测试

   [vagrant@localhost vagrant_data]$ java -version
   openjdk version "1.8.0_161"
   OpenJDK Runtime Environment (build 1.8.0_161-b14)
   OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

安装Elasticsearch

1. 执行以下命令

   curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.8.tar.gz
   tar -xvf elasticsearch-5.6.8.tar.gz
   cd elasticsearch-5.6.8/bin
   ./elasticsearch
   

2. 测试是否安装成功

   [vagrant@localhost elasticsearch-5.6.8]$ curl 'http://localhost:9200/?pretty'
   {"name" : "Lx20sHw","cluster_name" : "elasticsearch","cluster_uuid" : "gnYSlRb9TUqpVnBscm1-GQ","version" : {"number" : "5.6.8","build_hash" : "688ecce","build_date" : "2018-02-16T16:46:30.010Z","build_snapshot" : false,"lucene_version" : "6.6.1"},"tagline" : "You Know, for Search"
   }

安装报错处理

1. Vagrant内存不足报错

   [vagrant@localhost elasticsearch-5.6.8]$ ./bin/elasticsearchOpenJDK 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=NOpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12)## There is insufficient memory for the Java Runtime Environment to continue.# Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory.# An error report file with more information is saved as:# /vagrant_data/elasticsearch-5.6.8/hs_err_pid22178.log

   解决方法：

   • 打开Vagrantfile

   • 添加如下信息：

     config.vm.provider "virtualbox" do |v|
     v.memory = 2048
     v.cpus = 2
     end

   • 重启Vagrant vagrant reload

2. ElasticSearch 启动报错

      ERROR: [2] bootstrap checks failed[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536][2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

   解决方法：

   sudo vim /etc/security/limits.conf
   # 添加如下信息:
   # [当前用户名] hard nofile 65536
   # [当前用户名] soft nofile 65536
   # 保存退出

   sysctl -w vm.max_map_count=655360
   sysctl -a | grep "vm.max_map_count"

docker-compose 安装报错处理

• vm.max_map_count 报错

  grep vm.max_map_count /etc/sysctl.conf
  # 如果找不到，则在该文件中添加 vm.max_map_count=262144 然后执行 sysctl -p
  # 临时改变轻执行
  sysctl -w vm.max_map_count=262144
  

• 不能以root权限运行问题

  请检查Elasticsearch挂载的目录是否是root用户创建的
  

• Kibana链接问题

  直接通过docker-compose server name链接即可
  

• kibana无法登陆问题

  # 添加以下选项：
  XPACK_SECURITY_ENABLED: "false"
