早上发现网站 down 了,昨天也出现过一次,当时没在意,现在看日志是这样的: [Sat Sep 08 06:31:11.386913 2018] [mpm_event:notice] [pid 24219:tid 3074311936] AH00491: caught SIGTERM, shutting down
配置语法并没错误: helloiac@aliyun:~$ sudo apachectl configtest Syntax OK
google 原因,stackoverflow 最高票答案说是: The entries you see in the logs are almost certainly there because your provider used SIGTERM for that purpose.
这是说可能是外部因素导致的吗?
