nginx

nginx -t

查看nginx的配置文件是否语法正确

which nginx
rpm -ql nginx

查看nginx的位置

可以双server段进行配置，设置不同的server段限制

    server {
        listen       8001;
        listen       [::]:8001;
        server_name  localhost;
        charset      utf-8;

        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        error_page 404 /404.html;
        location = /404.html {
        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
    }


    server {
        listen 8000;
        listen [::]:8000;
        server_name minio.com;

        client_max_body_size 100M;
        client_body_buffer_size 1M;

        location / {
            proxy_pass http://localhost:8002;
        }
        #location /login {

    server {
        listen 9100;
        listen [::]:91;
        server_name mysql.com;

        client_max_body_size 100M;
        client_body_buffer_size 1M;

        location / {
            proxy_pass http://localhost:<port>;
        }
        # need requests
        location /login {
            proxy_pass http://localhost:<port>/<endpoint>;
        }
        location /datamanager {
            proxy_pass http://localhost:<port>/<endpoint>;
        }
        location /download/ {
            alias /data/share;
            autoindex on;
            autoindex_exact_size off;
            autoindex_localtime on;
        }

nginx 配置文件可以设置多个后台接口

注: 后台可以设置多个转发，endpoint可以配置django的URL 模块进行设置，作为WSGI服务器进行配合

#### jenkins配置

        location /jenkins {
            proxy_pass http://localhost:8010;
            #proxy_pass http://localhost:8080; # Jenkins默认运行在8080端口
            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_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Port $server_port;
        }

#### http段落优化

http {
    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;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
#    keepalive_timeout   65;
#    types_hash_max_size 4096;

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

    # 连接头优化
    keepalive_timeout 75s;
    keepalive_requests 10000;
    types_hash_max_size 2048;
    server_tokens off;       # 隐藏版本号

    # 缓冲区配置
    client_body_buffer_size 16k;
    client_header_buffer_size 2k;
    large_client_header_buffers 4 8k;

    # 超时设置
    send_timeout 20s;
    client_header_timeout 20s;
    client_body_timeout 20s;

    # worker_cpu_affinity  0001 0010 0100 1000;
    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

# 重启nginx配置

nginx -t
nginx -t -c /path/to/nginx.conf
sudo systemctl reload nginx
sudo nginx -s reload
sudo kill -HUP $(cat /run/nginx.pid)


systemctl status nginx  # 查看服务状态
ps -ef | grep nginx     # 确认新旧进程共存
curl -I http://localhost  # 测试服务响应

sudo systemctl revert nginx  # 回滚至上次有效配置

nginx配置加载

动态加载模块

也可以回滚配置，通过

systemctl revert nginx

检查这个目录是否可以访问

sudo -u nginx ls -ld /data/share
