centos7虚拟机安装elasticsearch5.0.x-安装篇
请预先安装jdk详细步骤请参考：//www.jb51.net/softjc/193398.html
创建新用户（非root用户）
elasticsearch只能用非root启动，这里我创建了一个叫seven的用户
[root@localhost ~]# useradd seven [root@localhost ~]# passwd seven
下载elasticsearch
[root@localhost ~]# su seven [seven@localhost root]$ cd /home/seven [seven@localhost ~]$ mkdir download [seven@localhost ~]$ cd download [seven@localhost download]$ wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/5.0.0-alpha3/elasticsearch-5.0.0-alpha3.tar.gz
解压并运行elasticsearch
解压
[seven@localhost download]$ tar -zxvf elasticsearch-5.0.0-alpha3.tar.gz
移动到指定文件夹并重命名（方便管理）
[seven@localhost download]$ mv elasticsearch-5.0.0-alpha3 /usr/java/elasticsearch
修改访问elasticsearch的IP及端口
[seven@localhost config]$ vim /usr/java/elasticsearch/config/elasticsearch.yml
找到如下代码段，并取消network.host及http.port所在行的注释，修改IP及端口
# ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 192.168.0.155 # # Set a custom port for HTTP: # http.port: 9200 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
直接运行bin/elasticsearch文件启动elasticsearch
[seven@localhost bin]$ cd /usr/java/elasticsearch/bin/ [seven@localhost bin]$ ./elasticsearch
启动时发现报错了。。。
[seven@localhost bin]$ ./elasticsearch
