查看nginx版本

[root@localhost ~]# nginx -v （注意是小v）
nginx version: nginx/1.12.

查看nginx安装了哪些模块

[root@localhost ~]# nginx -V（注意是大V）
nginx version: nginx/1.12.
built by gcc 4.8.  (Red Hat 4.8.-) (GCC)
built with OpenSSL 1.0.1e-fips  Feb
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-threads

可以格式化后显示

[root@localhost ~]# nginx -V >& | sed "s/\s\+--/\n --/g"
nginx version: nginx/1.12.

重读nginx配置文件

[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reopen

 检查配置文件是否正确

-t 参数 ，不运行nginx，而仅仅测试配置文件。nginx 将检查配置文件的语法的正确性，并尝试打开配置文件中所引用到的文件。

[root@localhost conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

后面也可以指定配置文件地址

[root@oa-dev conf]# /opt/app/nginx/sbin/nginx -t -c /opt/app/nginx/conf/nginx.conf
nginx: [warn] "ssl_stapling" ignored, issuer certificate not found for certificate "/opt/app/nginx/conf/ssl/server2018.crt"
nginx: the configuration file /opt/app/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /opt/app/nginx/conf/nginx.conf test is successful

查看nginx进程信息

[root@oa-dev conf]# ps -ef|grep nginx
root               : ?        :: nginx: master process /opt/app/nginx/sbin/nginx
nobody           : ?        :: nginx: worker process
nobody           : ?        :: nginx: worker process
