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

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
