Nginx의 로드밸런스 기능 이용

1. Nginx 의 Upstream 기능 추가

[root@rtls ~]# vi /etc/nginx/sites-available/flyyunha.conf

upstream upstream-flyyunha-server {

     server localhost:8311;   #8301로 들어온 요청을 8311, 8321 로 보내주는 설정

     server localhost:8321;

     keepalive 1000;

}

 

 

server {
    listen       8301;          #Listen Port 8301
    client_max_body_size 10M;
    server_name  192.168.1.1;   #해당 서버 IP

    charset utf-8;
    #charset koi8-r;
    #access_log  /data/logs/nginx_log/api_log/host.access.log  main;

    location / {
        proxy_pass http://upstream-flyyunha-server;   #해당 서버 IP 의 Tomcat 포트 8016
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
    }


    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

    #    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 {
