1.下载安装包
[root@localhost es]# wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.2.1/elasticsearch-2.2.1.tar.gz
2.解压
[root@localhost es]# tar -xvzf elasticsearch-2.2.1.tar.gz
3.创建一个普通用户，elasticsearch-2.x版本以后就不允许使用root账户启动
创建账号：
[root@localhost es]# useradd dd
设置密码：
[root@localhost es]# passwd 123456
4.给用户设置文件夹的权限，不然切换用户后运行会提示权限不足
[root@localhost es]# chown -R dd elasticsearch-2.2.1/
[root@localhost es]# chgrp -R dd elasticsearch-2.2.1/
5.切换用户
[root@localhost es]# su dd
6.进入bin文件夹启动服务
[dd@localhost es]$ cd elasticsearch-2.2.1/bin/
[dd@localhost bin]$ ./elasticsearch

或后台启动
[dd@localhost bin]$ ./elasticsearch -d -p pid
[dd@localhost bin]$
7.检查是否启动
[dd@localhost bin]$ curl localhost:9200
{
"name" : "Morg",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "2.2.1",
"build_hash" : "d045fc29d1932bce18b2e65ab8b297fbf6cd41a1",
"build_timestamp" : "2016-03-09T09:38:54Z",
"build_snapshot" : false,
"lucene_version" : "5.4.1"
},
"tagline" : "You Know, for Search"
}
8.注意：此时用外网或者局域网ip是不能访问的，如果要访问，按以下修改：
[dd@localhost bin]$ vim ../config/elasticsearch.yml
修改配置：
network.host: 0.0.0.0
注意配置项的冒号后要有空格，不然会报错
端口可以手动指定，也可以不指定，使用默认端口。
http.port: 9200
transport.tcp.port: 9300
9.安装head插件
插件安装格式为：./plugin install [org]/[user|component]/[version]
[root@localhost bin]# ./plugin install mobz/elasticsearch-head
-> Installing mobz/elasticsearch-head...
Trying https://github.com/mobz/elasticsearch-head/archive/master.zip ...
Downloading .............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................DONE
Verifying https://github.com/mobz/elasticsearch-head/archive/master.zip checksums if available ...
NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify)
Installed head into /opt/es/elasticsearch-2.2.1/plugins/head
10.关闭
在运行的时候如果加了-p参数，那es进程的pid会写入参数指定的文件里面，然后kill pid即可
还可以通过jps命令找到es的pid
[dd@localhost bin]$ ls
elasticsearch elasticsearch.in.bat elasticsearch-service-mgr.exe elasticsearch-service-x86.exe plugin service.bat
elasticsearch.bat elasticsearch.in.sh elasticsearch-service-x64.exe pid plugin.bat
[dd@localhost bin]$ cat pid
8406[dd@localhost bin]$
[dd@localhost bin]$ jps
8406 Elasticsearch
8796 Jps
[dd@localhost bin]$ kill -9 8406
11.外网访问要打开端口，CentOS7使用firewalld防火墙，无法使用iptables命令控制端口
查询端口是否打开：
[root@localhost elasticsearch-2.2.1]# firewall-cmd --query-port=9200/tcp
no
打开端口：
[root@localhost elasticsearch-2.2.1]# firewall-cmd --add-port=9200/tcp
success
9200和9300都要打开
查看规则：
[root@localhost elasticsearch-2.2.1]# iptables -L -n
外网就可以访问了
访问192.168.195.130:9200
可以看到一串json，说明访问成功
{
"name" : "Stegron",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "2.2.1",
"build_hash" : "d045fc29d1932bce18b2e65ab8b297fbf6cd41a1",
"build_timestamp" : "2016-03-09T09:38:54Z",
"build_snapshot" : false,
"lucene_version" : "5.4.1"
},
"tagline" : "You Know, for Search"
}
访问http://192.168.195.130:9200/_plugin/head 可以看到管理界面
elasticsearch的名字每次启动都会变化，都是漫威漫画里的角色。。。
