安装

解压，在根目录下修改 graphexp.html

<div class="nav input_unit_container">
        <label class="nav input_label" for="server_address">Server Address:</label>
        <input name="server_address" id="server_address" value="localhost" />
</div>
<div class="nav input_unit_container">
        <label class="nav input_label" for="server_port">Server port:</label>
        <input name="server_port" id="server_port" type="number" value="8182"/>
</div>

修改为，192.168.2.111:8182 为JanusGraph服务端口

<div class="nav input_unit_container">
        <label class="nav input_label" for="server_address">Server Address:</label>
        <input name="server_address" id="server_address" value="192.168.1.111" />
</div>
<div class="nav input_unit_container">
        <label class="nav input_label" for="server_port">Server port:</label>
        <input name="server_port" id="server_port" type="number" value="8182"/>
</div>

安装ngix 参考：https://www.runoob.com/linux/nginx-install-setup.html

修改配置文件 vim /usr/local/webserver/nginx/conf/nginx.conf

error_log /var/log/error.log debug;  #制定日志路径，级别。这个设置可以放入全局块，http块，server块，级别以此为：debug|info|notice|warn|error|crit|alert|emerg
events {
    accept_mutex on;   #设置网路连接序列化，防止惊群现象发生，默认为on
    multi_accept on;  #设置一个进程是否同时接受多个网络连接，默认为off
    #use epoll;      #事件驱动模型，select|poll|kqueue|epoll|resig|/dev/poll|eventport
    worker_connections  1024;    #最大连接数，默认为512
}
http {
    include       mime.types;   #文件扩展名与文件类型映射表
    default_type  application/octet-stream; #默认文件类型，默认为text/plain
    #access_log off; #取消服务日志
    log_format myFormat '$remote_addr–$remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for'; #自定义格式
    access_log /var/log/access.log myFormat;  #combined为日志格式的默认值
    sendfile on;   #允许sendfile方式传输文件，默认为off，可以在http块，server块，location块。
    sendfile_max_chunk 100k;  #每个进程每次调用传输数量不能大于设定的值，默认为0，即不设上限。
    keepalive_timeout 65;  #连接超时时间，默认为75s，可以在http，server，location块。

    upstream mysvr {
      server 127.0.0.1:7878;
      server 192.168.10.121:3333 backup;  #热备
    }
    error_page 404 https://www.baidu.com; #错误页
    server {
        keepalive_requests 120; #单连接请求上限次数。
        listen       4545;   #监听端口
        server_name  192.168.2.111;   #监听地址
        location  ~*^.+$ {       #请求的url过滤，正则匹配，~为区分大小写，~*为不区分大小写。
           root /opt/graphexp-master;  #插件目录
        }
    }
}
