==> box: Successfully added box 'es' (v0) for 'virtualbox'!

E:\vbox\es>vagrant init es

A `Vagrantfile` has been placed in this directory. You are now

ready to `vagrant up` your first virtual environment! Please read

the comments in the Vagrantfile as well as documentation on

`vagrantup.com` for more information on using Vagrant.

编辑Vagratnfile

Vagrant.configure("2") do |config|

	config.vm.network "forwarded_port", guest: 22, host: 2222, id: "ssh", disabled: "true"

	config.vm.network "forwarded_port", guest: 22, host: 5510

    config.vm.box = "lnmp"

    config.vm.network "private_network", ip: "192.168.55.10"

    config.vm.synced_folder "e:/www", "/www"

    config.vm.provider "virtualbox" do |v|

    v.memory = 2048

    v.cpus = 2

    end

end

启动 

E:\vbox\es>vagrant up

vagrant ssh  

修改root密码  
sudo passwd root

1 安装jdk

具体看 http://www.cnblogs.com/php-linux/p/8757783.html

2 下载 elasticsearch7.2

链接：https://pan.baidu.com/s/10Y8bBlHNEgLMMBQwMOiKCg
提取码：gvwc

后面基本和ceontos6安装一样，除了会报错说是要求java11 上面安装的是java8 解决方法 https://www.cnblogs.com/php-linux/p/13228710.html

3 解压

unzip elasticsearch-6.2.3.zip

4 移动

mv elasticsearch-6.2.3 /usr/local/es

5 启动

提示不能以root用户执行

useradd es
passwd es

为es用户添加sudo权限

visudo

找到root 复制后改为es

再次启动

估计是权限问题

sudo chmod 777 -R /usr/local/es

再启动

访问 http

　查看ip地址

访问

http://192.168.33.30:9200/

提示无法访问

vim /usr/local/es/config/elasticsearch.yml

再次重启

[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

解决：切换到root用户，编辑limits.conf 添加类似如下内容

vi /etc/security/limits.conf

添加如下内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

[2]: max number of threads [1024] for user [es] is too low, increase to at least [4096]

解决：切换到root用户，进入limits.d目录下修改配置文件。

vi /etc/security/limits.d/90-nproc.conf

修改如下内容：

* soft nproc 1024

#修改为

* soft nproc 4096

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

解决：切换到root用户修改配置sysctl.conf

vi /etc/sysctl.conf

添加下面配置：

vm.max_map_count=655360

并执行命令：

sysctl -p

[4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

问题原因：因为Centos6不支持SecComp，而ES5.2.1默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动。详见：https://github.com/elastic/elasticsearch/issues/22899

解决方法：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

重启es 异常

ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
修改
elasticsearch.yml
取消注释保留一个节点
cluster.initial_master_nodes: ["node-1"]
这个的话，这里的node-1是上面一个默认的记得打开就可以了

最终终于启动了

访问ip
