The following error occurred when the blogger started the Nginx service
[root@localhost ~]# /usr/local/nginx/sbin/nginx
nginx: [emerg] getpwnam("nginx") failed
The function of getPwnam in the error message is to get information about the user’s login
So you can see that getting “nginx” users failed
Query the user with id, and sure enough, it does not exist
[root@localhost ~]# id nginx
id: nginx: no such user
Once the user is added, it works
[root@localhost ~]# useradd -M -s /sbin/nologin nginx
[root@localhost ~]# /usr/local/nginx/sbin/nginx
[root@localhost ~]# netstat -anpt | grep nginx
tcp 0 0 10.0.0.100:80 0.0.0.0:* LISTEN 3843/nginx: master
Recall that the configuration for source code compilation and installation was as follows
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx && make && make install
At that time, the user group and user group of Nginx were set. In the absence of nginx users in the system, it could not be started naturally.
