1.打开opencms-system.xml配置文件：
<sites>
<workplace-server>http://localhost:8080</workplace-server>
<default-uri>/sites/default/</default-uri>
<shared-folder>/shared/</shared-folder>
<siteserver="http://localhost:8080" uri="/sites/default/"/>
</sites>2.将localhost改为服务器的IP地址（如192.168.0.10）：
<sites>
<workplace-server>http://192.168.0.10:8080</workplace-server>
<default-uri>/sites/default/</default-uri>
<shared-folder>/shared/</shared-folder>
<site server="http://192.168.0.10:8080" uri ="/sites/default/"/>
</sites>3.重启服务，即可使用IP地址访问后台页面。
