    我这里用的是JDK8u332，给管理员账号hxxx配置了用户环境变量（~/.bashrc）。

    有试过以root方式启动，启动成功了，但是日志与相关信息输出的文件的路径都和程序位置不匹配了（不好找）。

    我这里启动了数据库，启动了nacos等，以8688端口号启动服务正常跑起来了，但是以80端口号启动就失败，输出信息如下：

    启动命令就是下面这种

    java -jar s.jar > log.txt 2>&1 >&

    当我在前面先执行 sudo su就直接切换到root账号了，而这也启动失败：

    bash: java: 未找到命令

    显然，这个是因为我只给管理员账号配置了用户环境变量的缘故。

    另外一种处理方式是80端口通过NGINX转发，目前还没有尝试，不晓得是否存在问题。

    不知道谁晓得在管理员账号如何以80端口号启动服务？

    不建议使用root账户来搭建web服务，这是个安全习惯，不然别人从web入侵你的网站，直接就是root权限，你整个服务器都无所遁形，人家在浏览器里就能删除你服务器的所有文件。

    一般来说web服务要严格限制权限，一般比普通账户权限还低，能访问的目录严格限制在web目录下等等。这样即使有入侵，损失最大也就是这个web，不会波及别的。假如你服务器还有别的系统，用root启用web，所有系统都受这个网站影响。

    至于端口，每个软件配置端口的地方不一样，不是怎么在80端口开启服务的问题，而是你用的这个软件，怎么配置端口的问题

    另外你得看看80端口是不是已经占用了

    我这是新建的一个管理员账号来测试启动运行看看会出什么问题，如何解决它，没打算用root账号。

    启动输出日志已经打印出失败的原因了，在倒数第五行。不会是端口号占用的问题，如果是，之前改用root权限（有配置系统环境变量成功启动过，但是运行时部分文件数据路径不好找）启动会输出端口号占用的。另外，我改过端口号为8688启动成功运行了。

    修改端口号能启动，说明80端口被占用了，我的就是被lighttpd占用，我以80端口启动python服务器失败，改成8080就启动了。

    有道理，不过80端口除了调cap那就只剩root能开了（因为端口号太低了）

    当然NGINX反代也是个招

    目前已经通过NGINX转发解决！
