nginx: [error] invalid PID number ““ in “/data/nginx/logs/nginx.pid“

nginx修改配置文件后，重启时出现 nginx: [error] invalid PID number "" in "/data/nginx/logs/nginx.pid" 。意思是说不能在文件/data/nginx/logs/nginx.pid中找到有效的PID（进程号）

解决方法1：找到nginx的主进程号的pid写入nginx.pid文件，重新启动nginx

[root@yzil ~]# nginx -s reload
nginx: [error] invalid PID number "" in "/data/nginx/logs/nginx.pid"
[root@yzil ~]# ps aux | grep "nginx: master" | grep -v pts | awk '{print $2;}'
2847
[root@yzil ~]# ps aux | grep "nginx: master" | grep -v pts | awk '{print $2;}' > /data/nginx/logs/nginx.pid
[root@yzil ~]# nginx -s reload
[root@yzil ~]# 

解决方法2：杀死nginx主进程，重新启动nginx

[root@yzil ~]# killall nginx
[root@yzil ~]# nginx
