Elasticsearch安装（提前系统需要安装java环境）mac安装 brew install elasticsearch
centos安装
下载ElasticSearch安装包，https://www.elastic.co/downloads/elasticsearch运行下面命令将安装包移动到 /opt 目录，然后转到 opt 目录
mv elasticsearch-
2.3.
5.tar.gz /opt ; cd /opt
解压安装包,然后重命名为 elasticsearch
tar zxvf elasticsearch-
2.3.
5.tar.gz
mv elasticsearch-
2.3.
5 elasticsearch
进入elasticsearch/bin下运行elasticsearch脚本启动
cd elasticsearch/
./bin/elasticsearch
如果是用root账号启动，会报以下错误Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root. at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:285) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35) Refer to the log for complete error details.这是出于系统安全考虑设置的条件。由于ElasticSearch可以接收用户输入的脚本并且执行，为了系统安全考虑，建议创建一个单独的用户用来运行ElasticSearch创建elsearch用户组及elsearch用户
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
更改elasticsearch文件夹及内部文件的所属用户及组为elsearch:elsearch
cd /
opt
chown -R elsearch:elsearch elasticsearch
切换到elsearch用户再启动
su elsearch cd elasticsearch/
bin
./elasticsearch
ElasticSearch后端启动命令
./elasticsearch -d
安装后发现es以localhost可以访问，但是以本地ip却无法访问提示connection refused打开elasticsearch.yml 修改network.host 为 network.host:0.0.0.0注：如果启动时遇到下面类似的错误，可能是插件没有安装成功，删除plugins目录下的插件或者从新安装就可以了

安装Elasticsearch-Head 可视化插件进入到elasticsearch安装目录如mac下 cd /usr/local/opt/elasticsearch\@2.4/libexec/然后执行./bin/plugin install mobz/elasticsearch-headshield权限管理插件1.安装shield
bin/
plugin install license
bin/plugin install shield
2.重启es
bin/elasticsearch
3.添加管理员
bin/shield/esusers useradd adminName -r admin
adminName是可以自定义的，执行该命令以后会提示输入密码，再次输入密码进行确认，之后管理员用户就添加成功了。接下来访问es就需要输入账号密码了也可以直接访问（php里面直接用这个地址就可以了） http://用户名:密码@127.0.0.1:9200/shield用户管理增加用户增加用户：bin/shield/esusers useradd <username>增加用户同时设置密码：bin/shield/esusers useradd <username> -p <secret>增加用户同时设置角色：bin/shield/esusers useradd <username> -r <comma-separated list of role names>查询用户bin/shield/esusers list管理密码bin/shield/esusers passwd <username> -p <password>用户分配角色用-a增加角色，-r删除角色。bin/shield/esusers roles <username> -a <commma-separate list of roles> -r <commma-separate list of roles>删除用户bin/shield/esusers userdel <username>
