这似乎是一个重复的问题,但事实并非如此.我在其上发现了一些文章,其中start-stop-daemon不会创建PID文件.但就我而言,我已经创建了PID文件.我在服务器上执行此命令以启动Nginx：
/mnt/Nginx/logs/Nginx.pid
start-stop-daemon --start --quiet --pidfile /mnt/Nginx/logs/Nginx.pid --exec /usr/local/sbin/Nginx
PID文件已存在但仍然是start-stop-daemon不写入文件.我甚至尝试使用–make-pidfile选项,但是start-stop-daemon将错误的pid写入文件.
最佳答案
–make-pidfile选项是必需的. start-stop-daemon写“错误的pid”的原因是Nginx forks.这在start-stop-daemon手册页中有说明：
-m,--make-pidfile
Used when starting a program that does not create its own pid
file. This option will make start-stop-daemon create the file
referenced with --pidfile and place the pid into it just before
executing the process. Note,the file will not be removed when
stopping the program. NOTE: This feature may not work in all
cases. Most notably when the program being executed forks from
its main process. Because of this,it is usually only useful
when combined with the --background option.
