nginx错误日志解读

我正在运行 nginx，php 作为 fastcgi。我的网站有时会崩溃，需要重新启动 nginx 才能再次运行。我在错误日志中发现以下内容（出于隐私原因，实际 IP 已被替换）。有人能解释一下到底发生了什么吗？谢谢

答案1

bind() 到 0.0.0.0:80 失败 - 这意味着它无法绑定到端口 80，这通常意味着其他一些应用程序正在使用端口 80，您是否有可能同时意外地在此机器上运行了 apache？

14222228 write() 到“/var/log/nginx/access.log”失败（28：设备上没有剩余空间） - 通常意味着写入日志的卷上的磁盘已满，最好检查硬盘空间使用情况并根据需要清理旧文件或旧日志文件
