ES单机版安装步骤详解

 本篇博客的主要目的是介绍ES单机版的安装方式。

elasticsearch-5.4.3.tar.gz 百度云地址链接：https://pan.baidu.com/s/1z9yA2Ai34ZqiteMMifgx-A 提取码：y2zn

官网地址：https://www.elastic.co/cn/downloads/?elektra=home&storm=hero

a. tar开文件到指定的目录下面（创建软连接）

tar -zxvf elasticsearch-5.4.3.tar.gz -C /usr/local/software/

b. 修改配置文件

修改/usr/local/software/elasticsearch-5.4.3/config/elasticsearch.yml：

path.data: /usr/local/software/elasticsearch/data # ES数据的存放路径
path.logs: /usr/local/software/elasticsearch/logs # ES日志的存放路径
network.host: 192.168.140.101 # 当前节点绑定的IP地址
c. 创建用于存放数据与日志的目录

[root@s101 /usr/local/software/elasticsearch/config]#mkdir -p /usr/local/software/elasticsearch/data
[root@s101 /usr/local/software/elasticsearch/config]#mkdir -p /usr/local/software/elasticsearch/logs
d. 创建ES运行用户并修改ES目录权限

创建es用户

useradd es

更改用户密码（输入 123123）

passwd es
修改ES目录权限
chown -R es:es /usr/local/software/elasticsearch/
chown -R es:es /usr/local/software/elasticsearch/data/
chown -R es:es /usr/local/software/elasticsearch/logs/
e. 启动es服务

[es@s101 /usr/local/software/elasticsearch-5.4.3]$bin/elasticsearch

需要说明的是，如果你在第d步骤当中遇到了下面的错误：

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
第一：vim /etc/security/limits.conf修改用户最大可创建文件数，在文件的末尾添加：

• soft nofile 65536
• hard nofile 65536
  验证：ulimit -Hn查看可打开文件数量

[root@s101 /usr/local/software/elasticsearch-5.4.3]#ulimit -Hn
65536
第二：vim /etc/sysctl.conf修改最大虚拟内存大小，在文件的末尾添加：

vm.max_map_count=262144
验证：sysctl -p查看虚拟内存的大小

[root@s101 /usr/local/software/elasticsearch-5.4.3]#sysctl -p
vm.max_map_count = 262144
f. 验证es服务是否启动正常

方法1：

[root@s101 /root]#curl ‘http://192.168.140.101:9200/?pretty’
