大家好，我是烤鸭：

      又到了采坑实录。ngix莫名挂掉 error.log一直出现 signal process started
查看了access.log和error.log

access.log：

2019/01/07 10:07:16 [notice] 1393#0: signal process started

可以看得出来两个日志时间上是没有什么交集的。
我这个报错信息是比较明显的，open() "/opt/tools/tengine//logs/nginx.pid" failed (2: No such file or directory)。
虽然不知道为什么，配置文件没有改过，运行过一段时间没有问题，昨天第一次出现这个。
莫名其妙的tengine路径后面多了一个/。
原来的conf目录下的nginx.conf文件。

#user  nobody;
worker_processes  1;

error_log   logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

pid         logs/nginx.pid;

修改为

#user  nobody;
worker_processes  1;

error_log  /opt/tools/tengine/logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

pid        /opt/tools/tengine/logs/nginx.pid;

重新启动之后就可以了。

./nginx -c /opt/tools/tengine/conf/nginx.conf

虽然还不知道什么原因导致的nginx挂掉，观察一段时间再看。做个记录。
