centos 7 无痛安装 es

安装

1、装依赖

 yum install -y java-1.8.0-openjdk

2、安装elasticsearch

下载url：https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.3.tar.gz

• #目录创建    mkdir -p /opt/{soft,conf,logs,scripts};mkdir -p /data0/elasticsearch
• #文件解压缩    tar xzvf  elasticsearch-5.6.3.tar.gz -C /opt/soft/
• #建立软连接  ln -s /opt/soft/elasticsearch-5.6.3 /opt/soft/elasticsearch
• #添加elastic 用户 adduser elastic -d /opt/soft/elasticsearch -s /sbin/nologin
• #权限赋予   chown -R elastic.elastic /opt/soft/elasticsearch; chown -R elastic.elastic  /data0/elasticsearch

3、配置文件修改

  3.1  系统配置文件：

      3.1.1 #vi  /etc/security/limits.conf

 #追加如下内容

elastic soft memlock unlimited
elastic hard memlock unlimited

# End of file
* soft nproc unlimited
* hard nproc unlimited
* soft nofile 655350
* hard nofile 655350

     3.1.2 # vi /etc/sysctl.conf  

#追加如下内容：

vm.max_map_count=262144

    3.1.3 #编辑init 文件

#  vi /etc/init.d/elasticsearch 

#根据自身情况，修改如下内容

#具体内容

#!/bin/bash
#
# elasticsearch <summary>
#
