项目配置维护界面

1.修改nginx.conf

cat > nginx.conf <<'EOF'

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

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

    # =========================================================
    # 前置代理真实 IP
    #
    # 只有 192.168.36.228 这个前置代理发送过来的
    # X-Forwarded-For 才信任
    # =========================================================

    set_real_ip_from 192.168.36.228;

    real_ip_header X-Forwarded-For;

    real_ip_recursive on;


    # =========================================================
    # 维护模式开关
    #
    # 0 = 正常模式
    # 1 = 维护模式
    #
    # 维护模式：
    #   **********     → 正常项目
    #   其他 IP        → 维护页面
    # =========================================================

    map $remote_addr $maintenance_mode {
        default          0;
        125.64.214.131   0;
    }

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    client_max_body_size 200m;
    client_body_timeout 300;

    include /etc/nginx/conf.d/*.conf;
}

EOF

2.修改项目配置文件

vim /etc/nginx/conf.d/nxyyedu.conf 
server {
    listen 443;

    server_name app.admin.sjdit.com;
    ssl_certificate /etc/nginx/cert/_.sjdit.com.crt;
    ssl_certificate_key /etc/nginx/cert/_.sjdit.com.key;
    # ssl_session_timeout 5m;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
    ssl_prefer_server_ciphers on;

    charset utf-8;

    client_max_body_size 2048m;


    # =========================================================
    # 项目资源
    #
    # 维护模式：

    #   其他 IP        → 维护页面
    # =========================================================
    location / {

        if ($maintenance_mode = 1) {
            return 418;
        }

        root /usr/share/nginx/html/chdit-edu-ybsz-core-web;

        try_files $uri $uri/ /index.html;
    }

    location /api/ {
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://192.168.36.190:8720/;
    }


    location /oauth2/ {

        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://192.168.36.190:8781;

        proxy_pass http://192.168.36.190:8768/ping-code/endpoint/create;
    }


    # =========================================================
    # 维护页面
    # =========================================================
    error_page 418 =200 @maintenance;


    location @maintenance {

        root /usr/share/nginx/html/maintenance;

        # 强制在当前 named location 内部读取维护页面
