rpm包安装

				?

									#安装nginx，rpm安装

									#rpm安装nginx包

									rpm -Uvh --force --nodeps nginx-1.16.1-1.el7.ngx.x86_64.rpm

									#查看启动状态

									systemctl status nginx

									显示如下:

									● nginx.service - nginx - high performance web server

									#启动

									systemctl start nginx

									#重启

									systemctl restart nginx

									#开机自启动服务

									systemctl enable nginx

									#查看开机启动状态 enabled:开启, disabled:关闭

									systemctl is-enabled nginx

安装完后在修改 /etc/nginx/conf.d/default.conf 配置文件，参考内容如下：

				?

									vim /etc/nginx/conf.d/default.conf

					?

										server {

										    listen       80;

										    server_name  localhost;

										    #charset koi8-r;

										    #access_log  /var/log/nginx/host.access.log  main;

										     location /ui {

										        alias   /data/dist;

										        index  index.html index.htm;

										     }

										     location /file/ {

										         root   /home/data/;

										        index  index.html index.htm;

										     }    

										    # websocket配置wss

										    location /liangws/ {

										        proxy_pass http://192.168.0.19:8080/;

										        proxy_http_version 1.1;

										        proxy_set_header Upgrade $http_upgrade;

										        proxy_set_header Connection "upgrade";

										        proxy_set_header Remote_addr $remote_addr;

										        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

										        proxy_read_timeout 600s;

										    }

										    location ~ /gat {

										        proxy_set_header Host  $host;

										        proxy_set_header X-Real-IP $remote_addr;

										        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

										        proxy_pass http://localhost:18080 ;

										    }

										    #error_page  404              /404.html;

										    # redirect server error pages to the static page /50x.html

										    #

										    error_page   500 502 503 504  /50x.html;

										    location = /50x.html {

										        root   /usr/share/nginx/html;

										    }

										    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

										    #

										    #location ~ \.php$ {

										    #    proxy_pass   http://127.0.0.1;

										    #}

										    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

										    #

										    #location ~ \.php$ {

										    #    root           html;

										    #    fastcgi_pass   127.0.0.1:9000;

										    #    fastcgi_index  index.php;

										    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

										    #    include        fastcgi_params;

										    #}

										    # deny access to .htaccess files, if Apache's document root

										    # concurs with nginx's one

										    #

										    #location ~ /\.ht {

										    #    deny  all;

										    #}

										}

注意：静态文件下载，需要依赖nginx，我们需要将这些文件放到 nginx配置文件中的 /home/data/aaa 对应的目录下。
