linux下安装elasticsearch5.6.3
1.准备工作
确保系统已经安装jdk1.8及以上版本
2.下载es
下载地址：wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.0.0.tar.gz
3.解压安装
添加用户
useradd elasticsearch
解压
tar xf elasticsearch-5.6.3.tar.gz -C /usr/local
cd /usr/local
设置软链
ln -sv elasticsearch-5.6.3 elasticsearchmkdir -pv /data/elasticsearch/{data,logs}chown -R elasticsearch.elasticsearch /data/elasticsearch注意：在安装过程中，不建这2个文件夹，启动时会报错，找不到这两个路径。
mkdir -p /usr/local/elasticsearch/plugins
mkdir -p /usr/local/elasticsearch/config/scripts4.修改配置文件
/usr/local/elasticsearch/config/elasticsearch.yml配置文件中新增内容如下
# 换个集群的名字，免得跟别人的集群混在一起
cluster.name: wlt-es5.0-application
# 换个节点名字
node.name: node-1
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs
# 修改一下ES的监听地址，这样别的机器也可以访问
network.host: 0.0.0.0
# 默认的就好
http.port: 9200
# 增加新的参数，这样head插件可以访问es
#http.cors.enabled: true
#http.cors.allow-origin: “*"
5.修改系统参数
编辑limit.conf文件 /etc/security/limits.conf
内容如下
* soft nproc 65536 * hard nproc 65536 * soft nofile 65536 * hard nofile 65536
继续编辑sysctl.conf文件 /etc/sysctl.conf
内容如下
vm.max_map_count= 262144
编辑完成后执行指令 sysctl -p 使配置生效
注：如果遇到limit.conf文件没有生效的情况下，可执行命令 ulimit -n 65536 临时添加limit.conf中最大打开文件数配置
6.启动es服务
进入/usr/local 路径下，切换至上面添加的elasticsearch用户
指令如下
cd /usr/local
su elasticsearch
启动es
cd /elasticsearch/bin
./elasticsearch
启动完成
启动可能会遇到的问题：
1.elasticsearch安装目录权限不对
遇到启动elasticsearch失败，使用的是专门的用户elasticsearch来启动的，启动日志提示不能加载配置文件：
[elasticsearch@docker bin]$ ./elasticsearch

解决方案
看到“Caused by: java.nio.file.AccessDeniedException: /usr/local/elasticsearch-5.6.3/config/elasticsearch.yml”的提示，
就去检查目录的权限，果然是root:root权限，
使用elasticsearch用户去启动，就报错了。
将目录的权限改成elasticsearch:elasticsearch就好了。
