打开上图的Makefile文件，可以看到下图：

nginx相关命令

上面那样，找到nginx的exe后，可以如下执行，查看支持的参数：

[root@VM-0-6-centos nginx]# ./nginx -h
nginx version: nginx/1.21.3
Usage: nginx [-?hvVtTq] [-s signal] [-p prefix]
             [-e filename] [-c filename] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/local/nginx/)
  -e filename   : set error log file (default: logs/error.log)
  -c filename   : set configuration file (default: /usr/local/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

里面的nginx -V就可以查看到当初configure安装时候的参数：

[root@VM-0-6-centos nginx]# ./nginx -V
nginx version: nginx/1.21.3
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module

检查配置文件语法：

[root@VM-0-6-centos nginx]# ./nginx -t
nginx: the configuration file /usr/local/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/nginx.conf test is successful

检查配置文件语法并打印：

[root@VM-0-6-centos nginx]# ./nginx -T
nginx: the configuration file /usr/local/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/nginx.conf test is successful
# configuration file /usr/local/nginx/nginx.conf:

#user  nobody;
worker_processes  1;

子进程的数量：

#user  nobody;
worker_processes  1;

[root@VM-0-6-centos nginx]# ps -ef|grep nginx
