1，安装配置JDK 8
参考：官方文档
＃为什么是JDK1.8？在ElasticSearch6.2.4中提到：JDK版本必须为：1.8.0_131 以上
> 1，安装JDK1.8-161
＃解压tar.gz
tar -zxvf jdk-8u161-linux-x64.tar.gz
> 2，配置环境变量
vim /etc/profile.d/dev.sh # Set Dev Path JAVA_HOME=/usr/local/java/jdk1.8.0_161/ export JAVA_HOME export PATH=$PATH:$JAVA_HOME/bin
＃生效变量
source /etc/profile.d/dev.sh
[root@ gameServer local] java -version java version "1.8.0_161" Java(TM) SE Runtime Environment (build 1.8.0_161-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)
2，增加用户（ElasticSearch不允许Root启动）
Root启动异常为:can not run elasticsearch as root
[root@gameServer local] #adduser payment [root@gameServer local]＃passwd payment Changing password for user payment. New password: BAD PASSWORD: The password is shorter than 8 characters Retype new password: passwd: all authentication tokens updated successfully.
3，下载ElasticSearch
[payment@gameServer ~]$ cd elasticSearch/ [payment@gameServer elasticSearch]$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz --2018-06-05 21:14:44-- https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz 正在解析主机 artifacts.elastic.co... 54.235.171.120, 54.235.82.130, 23.21.67.46, ... 正在连接 artifacts.elastic.co|54.235.171.120|:443... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：29056810 (28M) [binary/octet-stream] 正在保存至: “elasticsearch-6.2.4.tar.gz” 100%[========================================================================================>] 29,056,810 387K/s in 93s 2018-06-05 21:16:19 (304 KB/s) - 已保存 “elasticsearch-6.2.4.tar.gz” [29056810/29056810]) [payment@gameServer elasticSearch]$ tar -zxvf elasticsearch-6.2.4.tar.gz [payment@gameServer elasticSearch]$ cd elasticsearch-6.2.4
4，配置ElasticSearch和Linux
[payment@gameServer elasticsearch-6.2.4]$ vim config/elasticsearch.yml # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 172.17.63.15 # # Set a custom port for HTTP: # http.port: 9200
5、 启动ElasticSearch
eg:如果报错不要慌张、随后有解决方案
1>、控制台启动：

2、控制台启动下：停止(Ctrl+C)

3、后台启动
[payment@gameServer elasticsearch-6.2.4]$ ./bin/elasticsearch -d
[payment@gameServer elasticsearch-6.2.4]$
4、验证
[payment@gameServer elasticsearch-6.2.4]$ curl "http://172.17.63.15:9200" { "name" : "SdEluaQ", "cluster_name" : "elasticsearch", "cluster_uuid" : "Oz0crt7uRTeVgPX0EFZ3Kg", "version" : { "number" : "6.2.4", "build_hash" : "ccec39f", "build_date" : "2018-04-12T20:37:28.497551Z", "build_snapshot" : false, "lucene_version" : "7.2.1", "minimum_wire_compatibility_version" : "5.6.0", "minimum_index_compatibility_version" : "5.0.0" }, "tagline" : "You Know, for Search" }

6、安装相关问题汇总：
1>、Centos6 安装启动失败：
ERROR: [1] 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
解决方案 参考文档：
[payment@gameServer elasticsearch-6.2.4]$ vim config/elasticsearch.yml # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # bootstrap.memory_lock: false bootstrap.system_call_filter: false # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory.
2>、ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536] max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]
解决方案：Root用户修改
vim /etc/security/limits.conf
添加如下内容:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
3>、max number of threads [1024] for user [lish] likely too low, increase to at least [4096]
解决方案:Root用户修改
vim /etc/security/limits.d/90-nproc.conf * soft nproc 4096 root soft nproc unlimited
4>，最大虚拟内存区域vm.max_map_count [65530]可能太低，增加到至少[262144]
解决方案：根用户修改
vim /etc/sysctl.conf
＃添加如下配置并保存
vm.max_map_count = 655360
[root @ gameServer〜]＃sysctl -p net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 vm.max_map_count = 655360
