安裝

解壓，在根目錄下修改?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>

修改為，192.168.2.111:8182?為JanusGraph服務(wù)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>

安裝ngix?參考：https://www.runoob.com/linux/nginx-install-setup.html

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

啟動服務(wù)：/usr/local/webserver/nginx/sbin/nginx

打開 gremlin.sh?

注意：conf/remote.yaml?文件中配置著JanusGraph服務(wù)端口
