Elasticsearch本地 && docker-compose 安装

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/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     OpenJDK 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 [vagrant@localhost elasticsearch-5.6.8]$ free -m                   total        used        free      shared  buff/cache   available     Mem:            488         101          88           3         297         340     Swap:          1535           1        1534

    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"
