elasticsearchan安装

1. yum方式下载安装java

	服务器系统：centos7 64bit
	jdk版本：jdk1.7 64bit

命令：

# yum install java-java-1.8.0-openjdk.x86_64

成功后显示：

Dependency Installed:
  pcsc-lite-libs.x86_64 0:1.8.8-8.el7

Complete!

• 通过yum安装的默认路径为：/usr/lib/jvm 将
• jdk的安装路径加入到JAVA_HOME

vi /etc/profile

在文件最后加入：

#set java environment
JAVA_HOME=/usr/lib/jvm/jre-1.6.0-openjdk.x86_64
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME CLASSPATH PATH

写好后按esc进入底部命令模式，输入：wq保存并退出

-使配置文件生效

. /etc/profile （注意 . 之后应有一个空格）

运行后不报错即为立即生效了

[root@haha jvm]# . /etc/profile
[root@haha jvm]# java -version
openjdk version "1.8.0_222"

2安装els

命令：

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.1-linux-x86_64.tar.gz
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.1-linux-x86_64.tar.gz.sha512
shasum -a 512 -c elasticsearch-7.4.1-linux-x86_64.tar.gz.sha512 
tar -xzf elasticsearch-7.4.1-linux-x86_64.tar.gz
cd elasticsearch-7.4.1/ 

如果提示shasum命令找不到就试试yum install perl-Digest-SHA 我运行后就好使了
中途提示 选y就好

3切换用户

不能用root用户去执行els，为了你的系统安全，如果不是root用户跳过此步，进入4

• adduser putao //添加新用户 pas
• swd putao //给新用户配密码

[root@haha elasticsearch-7.4.1]# adduser putao
[root@haha elasticsearch-7.4.1]# passwd putao
Changing password for user putao.
New password: 
BAD PASSWORD: The password is shorter than 8 characters
Retype new password: 
passwd: all authentication tokens updated successfully.

将这几个压缩包所在的文件夹及解压完的文件夹权限给你新建的用户。之后再使用新用户启动就OK了。

[root@haha jvm]# chown -R putao elasticsearch-7.4.1
[root@haha jvm]# cd ../
[root@haha lib]# chown -R putao jvm

切换到新用户，进入文件夹运行els

[root@haha lib]# su putao
[putao@haha lib]$ cd jvm/elasticsearch-7.4.1
[putao@haha elasticsearch-7.4.1]$ ./bin/elasticsearch
