环境准备

由于elasticsearch由Java实现,所以需要Java环境,请自行百度安装。

创建用户和密码(root用户下)

elasticsticsearch不能用root用户去启动,否则会报错,所以在这里我将会单独创建一个名为elasticsearch的用户,去运行elasticsearch程序,当前用户是root,所以无需切换,直接运行如下命令:
创建密码,这里会有两次密码输入提示,确保一致即可创建完成!

[root@localhost soft]# useradd elasticsearch
[root@localhost soft]# passwd elasticsearch
Changing password for user elasticsearch.
New password: elasticsearch
Retype new password: elasticsearch
passwd: all authentication tokens updated successfully.

下载和安装elasticsearch

elasticsearch内存配置

elasticsearch5.5版本默认是需要分配2G内存,否则启动时会报错,类似如下:

INFO: os::commit_memory(0x00000000ea660000, 362414080, 0) failed; error='Cannot allocate memory' (errno=12)

如果你的内存不够,打开并编辑/usr/local/elasticsearch-5.5.2/config/jvm.options文件,将文件开始位置的配置修改,则可以解决,例如我将2G的默认配置修改称为512M,只需要删除或者使用#注释掉原来配置再添加自己的配置项即可,类似如下:

# 注释掉的原来的2G配置
#-Xms2g
#-Xmx2g

# 修改称为512M内存大小
-Xms512m
-Xmx512m

登录elasticsearch用户,并将程序目录加入环境变量

[root@localhost elasticsearch-5.5.2]# su elasticsearch
[elasticsearch@localhost elasticsearch-5.5.2]$ who -m
elasticsearch      pts/0        2017-10-19 14:16 (192.168.174.1)

确保当前用户为elasticsearch后,编辑~/.bash_profile文件,在export $PATH之前加入如下行,保存退出即可:

export PATH=/usr/local/elasticsearch-5.5.2/bin:$PATH

使新增的环境变量生效

[elasticsearch@localhost elasticsearch-5.5.2]$ source ~/.bash_profile

运行elasticsearch

[elasticsearch@localhost elasticsearch-5.5.2]$ elasticsearch

测试elasticsearch

新开一个登录窗口,任何用户登录都行,这里需要使用到curl,如果没有,以centos为例自行yum安装即可,确保没问题后,最终执行如下命令:

[elasticsearch@localhost ~]$ curl http://localhost:9200
{
  "name" : "JiJUcOE",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "4gwlK6HLSs68pZI6uXv6bg",
  "version" : {
    "number" : "5.5.2",
    "build_hash" : "b2f0c09",

    "build_snapshot" : false,

  },
  "tagline" : "You Know, for Search"
}
