CentOS rpm安装Nginx和配置

官方下载地址: http://nginx.org/en/download.html

介绍

Nginx(“engine x”)是一款由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。

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
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
   Active: active (running) since 五 2021-11-26 11:12:41 CST; 5 days ago

#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。
