本文使用linux版本为CentOS6.8，ES版本为6.2.4，安装包可以从官网下载
https://www.elastic.co/cn/downloads/past-releases/elasticsearch-6-2-4
1.将elasticsearch-6.2.4.tar.gz上传至Linux系统/opt/software目录下，解压到/opt/module/目录下
[root@hadoop130 software]# tar -zxvf elasticsearch-6.2.4.tar.gz -C /opt/module/
elasticsearch-6.2.4/
elasticsearch-6.2.4/lib/
elasticsearch-6.2.4/lib/elasticsearch-6.2.4.jar

elasticsearch-6.2.4/lib/lucene-core-7.2.1.jar
elasticsearch-6.2.4/lib/lucene-analyzers-common-7.2.1.jar
elasticsearch-6.2.4/lib/lucene-backward-codecs-7.2.1.jar
......
2.进入bin目录下启动ES
[root@hadoop130 elasticsearch-6.2.4]# cd bin/
[root@hadoop130 bin]# ./elasticsearch

原因: Centos6不支持SecComp,而ES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不能启动解决:修改elasticsearch.yml 添以下内容 ：
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
重新启动<(￣ ﹌ ￣)>

3.另开终端测试是否可以正常使用
[yzl@hadoop130 ~]$ curl 127.0.0.1:9200
{
"name" : "v-Ors61",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "fetCUVvXTqqCe0gJOBeeUw",
"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"
}
一切正常ヽ(ﾟ∀ﾟ)ﾒ(ﾟ∀ﾟ)ﾉ
4.配置远程访问
修改elasticsearch.yml文件
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
192.168.0.1改为当前服务器IP地址
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.32.130
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
重新启动，居然又失败了ヽ(#`Д´)ﾉ┌┛〃

一个一个来解决。。。
(1)
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
原因：每个进程最大同时打开文件数太小，可通过下面2个命令查看当前数量
ulimit -Hn
ulimit -Sn
[yzl@hadoop130 bin]$ ulimit -Hn
4096
[yzl@hadoop130 bin]$ ulimit -Sn
1024
修改/etc/security/limits.conf文件，最后追加如下配置，xxx是使用ES的用户名，用户退出后重新登录生效
xxx hard nofile 65536
xxx soft nofile 65536
（2）
max number of threads [1024] for user [yzl] is too low, increase to at least [4096]
问题同上，最大线程个数太低。修改配置文件/etc/security/limits.conf（和问题1是一个文件），增加配置
xxx hard nproc 4096
xxx soft nproc 4096
(3)
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
修改/etc/sysctl.conf文件，增加配置vm.max_map_count=262144
执行sysctl -p命令后生效
[root@hadoop130 yzl]# 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.shmmax = 68719476736
kernel.shmall = 4294967296
vm.max_map_count = 262144
reboot后启动ES
