近来由于工作需求,和nginx接触较多,现把关于nginx进程属主的问题总结如下:
规则
nginx启动进程可以在conf里指定user(user work;)但是这个只有在用root启动的情况有意义,
如果是用其他用户启动的nginx master是没有意义的 nginx会忽略这个配置,如下nginx warning所述
nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /home/work/app/nginx/conf/nginx.conf:1
结论
1,在非root账户下启动时,nignx的master和worker进程的owner都将是这个账户,
2,在root账户下启动时 nignx的master进程是的owner是root,worker的owner在conf已配置用户的情况下,owner是配置的用户,否则将是nobody,而且也可能导致nginx的一些文件的owner也是nobody
