1、 查看服务器上安装的nginx版本号，主要是通过nginx的-v或-V选项，查看方法如下图所示
-v 显示 nginx 的版本。
-V 显示 nginx 的版本，编译器版本和配置参数
[root@zq ~]# nginx -Vnginx version: nginx/1.16.1built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)built with OpenSSL 1.0.2k-fips 26 Jan 2017TLS SNI support enabledconfigure arguments: –prefix=/etc/nginx –sbin-path=/usr/sbin/nginx –modules-path=/usr/lib64/nginx/modules –conf-path=/etc/nginx/nginx.conf –error-log-path=/var/log/nginx/error.log –http-log-path=/var/log/nginx/access.log –pid-path=/var/run/nginx.pid –lock-path=/var/run/nginx.lock –http-client-body-temp-path=/var/cache/nginx/client_temp –http-proxy-temp-path=/var/cache/nginx/proxy_temp –http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp –http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp –http-scgi-temp-path=/var/cache/nginx/scgi_temp –user=nginx –group=nginx –with-compat –with-file-aio –with-threads –with-http_addition_module –with-http_auth_request_module –with-http_dav_module –with-http_flv_module –with-http_gunzip_module –with-http_gzip_static_module –with-http_mp4_module –with-http_random_index_module –with-http_realip_module –with-http_secure_link_module –with-http_slice_module –with-http_ssl_module –with-http_stub_status_module –with-http_sub_module –with-http_v2_module –with-mail –with-mail_ssl_module –with-stream –with-stream_realip_module –with-stream_ssl_module –with-stream_ssl_preread_module –with-cc-opt=’-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong –param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC’ –with-ld-opt=’-Wl,-z,relro -Wl,-z,now -pie’
2、使用rpm -qa | grep nginx查看nginx版本
[root@zq ~]# rpm -qa | grep nginx
nginx-1.16.1-1.el7.ngx.x86_64
3、使用curl -i 127.0.0.1
[root@zq ~]# curl -i 127.0.0.1
