服务器直接部署ES

https://www.elastic.co/cn/downloads/past-releases#elasticsearch

选择6.8.8版本

https://www.elastic.co/guide/en/elasticsearch/reference/6.8/zip-targz.html

官方文档，安装说明

1、先安装java

https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

选择【Linux x64 RPM Package】

rpm -ivh jdk-8u251-linux-x64.rpm

warning: jdk-8u251-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID

2、下载elasticsearch软件，解压到/usr/locl目录下

[root@host101 ~] tar xvf elasticsearch-6.8.8.tar.gz -C /usr/local/
[root@host101 ~] cd /usr/local/
[root@host101 local] mv elasticsearch-6.8.8/ elasticsearch

3、运行elasticsearch,开启报错之旅

3.1报错：

不能以root用户运行，

[root@host101 elasticsearch]# bin/elasticsearch
OpenJDK 64-Bit Server VM warning: If the number of processors is
expected to increase from one, then you should configure the number of

解决方法：

添加其它用户，我新加了一个es用户，将elasticsearch目录授予es用户,启动成功。

[root@host101 elasticsearch]# useradd es
[root@host101 elasticsearch]# chown -R es:es /usr/local/elasticsearch/
[root@host101 elasticsearch]#su - es

3.2

但默认监控的是127.0.0.1端口，其它IP访问不到ES数据库，需要修改为本机Ip  192.168.150.101

[root@host101 config]# cd /usr/local/elasticsearch/config/
[root@host101 config]# vi elasticsearch.yml

修改这个参数

network.host: 192.168.150.101

保存！

重启数据库，报错

需要使用root用户去修改

low, increase to at least [65535]
[2]: max virtual memory areas vm.max_map_count [65530] is too low,
increase to at least [262144]

[root@host101 config] vi /etc/security/limits.conf

# 添加至尾部
* soft nofile 65536
* hard nofile 65536

[root@host101 config] vi /etc/sysctl.conf

# 添加至尾部
vm.max_map_count=262144

# 验证是否生效
[root@host101 config] sysctl -p
vm.max_map_count = 262144

使用curl命令测试一下，或在浏览器中输入 http://192.168.150.101:9200/ 也会返回相同的信息，单节点安装完成。

以守护进程进行启动：

./bin/elasticsearch -d -p pid

pid将保存在执行命令时所在目录

添加认证：

vi ./config/elasticsearch.yml

#set auth
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

保存后执行

./bin/elasticsearch-setup-passwords interactive

添加认证后测试9200

curl -u elastic:password http://192.168.0.1:9200
