问题场景
服务器重启后，重启nginx时报错nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)，进入到logs目录发现确实没有nginx.pid文件
cd /usr/local/nginx/sbin/
./nginx -s reload
ngx_http_fastdfs_set pid=1412
ngx_http_fastdfs_set pid=1412
ngx_http_fastdfs_set pid=1412
ngx_http_fastdfs_set pid=1412
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
解决办法
使用指定nginx.conf文件的方式重启nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
此时去logs目录下查看发现nginx.pid文件已经生成了
