一、修改es启动的host

vi  config/elasticsearch.yml

network.host:192.168.76.77
    http.port: 9200

再次启动

如果上次没有关闭es，会报错

把进程杀死即可，再次启动，一般会报如下三个错误

ERROR: \[3\] bootstrap checks failed

\[1\]: max file descriptors \[4096\] for elasticsearch process is too low, increase to at least \[65535\]

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

\[3\]: 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

二、配置linux的线程内存和文件（处理第一个错误）：

vi /etc/security/limits.conf 文件最后，但是在  \#End of file之前  加入

* soft nofile 65536
    * hard nofile 65536
    * soft nproc 4096
    * hard nproc 4096

三、配置系统允许的软件允许内存（处理第二个错误）：

vi /etc/sysctl.conf

vm.max_map_count = 655360
    fs.file-max=655360

执行以下命令生效： sysctl -p

四、保留一个节点（处理第三个错误）：

vi  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

随便看一下这个文件，一般不会有问题，如下图即可

vi /etc/security/limits.d/20-nproc.conf

五、开启端口9200

firewall-cmd --zone=public --add-port=9200/tcp

六、启动 ./elasticsearch

浏览器访问
