nginx: [error] invalid PID number

根据引用内容，出现"nginx: [error invalid PID number"的错误提示是因为在文件/tmp/nginx.pid中找不到有效的PID(进程ID)。解决这个问题有两种方法。第一种方法是杀掉所有的nginx进程，然后使用-c命令指定配置文件重新启动nginx。具体步骤如下：进入/usr/local/nginx/sbin/目录，使用killall -9 nginx命令杀掉所有的nginx进程，使用./nginx -t命令检查配置文件是否有错误，最后使用./nginx -c /usr/local/nginx/conf/nginx.conf命令指定配置文件重新启动nginx。第二种方法是检查nginx.conf文件中的nginx.pid是否被注释掉了。 [2 [3<em>1</em><em>2</em><em>3</em>
