[emerg] open() "/usr/local/Cellar/nginx/1.17.10/logs/error.log" failed (2: No such file or directory

启动nginx时报：[emerg] open() "/usr/local/Cellar/nginx/1.17.10/logs/error.log" failed (2: No such file or directory)

解决办法是去/usr/local/Cellar/nginx/1.17.10/ 目录下，先创建logs目录，然后再新建error.log文件

启动nginx时报：[warn] 1024 worker_connections exceed open file resource limit: 256

 

 worker_connections: 单个后台worker process进程的最大并发链接数worker_connections；

控制台执行：ulimit -a，显示如下，将红色字的变量改为1024即可，使用命令ulimit -n 1024。

然后重启

 重启后，访问localhost，成功！
