（一）环境

（二）安装步骤

2、设置nginx安装源

[root@FreeRadius4 ~]# vim /etc/yum.repos.d/nginx.repo[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/7/$basearch/gpgcheck=0enabled=1###具体可以参考nginx官网文档（http://nginx.org/en/linux_packages.html#stable）

3、安装nginx

4、创建nginx服务的相关操作

[root@FreeRadius4 ~]# systemctl enable nginxCreated symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.[root@FreeRadius4 ~]# systemctl start  nginx[root@FreeRadius4 ~]# systemctl status  nginx● nginx.service - nginx - high performance web server   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)   Active: active (running) since Wed 2018-09-26 15:59:41 CST; 3s ago     Docs: http://nginx.org/en/docs/  Process: 6621 ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf (code=exited, status=0/SUCCESS) Main PID: 6622 (nginx)    Tasks: 2   Memory: 1.5M   CGroup: /system.slice/nginx.service           ├─6622 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf           └─6623 nginx: worker processSep 26 15:59:41 FreeRadius4 systemd[1]: Starting nginx - high performance web server...Sep 26 15:59:41 FreeRadius4 systemd[1]: Started nginx - high performance web server.[root@FreeRadius4 ~]# nginx -Vnginx version: nginx/1.14.0built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (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'[root@FreeRadius4 ~]# nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful

5、nginx相关配置文件/etc/nginx/nginx.conf下

（三）编译安装
