oneinstack在配置ssl的时候nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)

在配置HTTPS的时候：Do you want to redirect all HTTP requests to HTTPS? [y/n]: y  输入了y，出现了

nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)

遇到这个问题进入nginx.conf的文件目录下运行语句：nginx -c /usr/local/nginx/conf/nginx.conf

然后再运行nginx -s reload就行
