初探nginx負載均衡配置

只簡單說一下upstream的配置，如何進行負載均衡後續還須要多瞭解

1.另準備一個配置文件命名爲nginx_test.conf

爲了避免污染原有的nginx.conf，提早複製一份配置文件作試驗，而後啓動nginx時加載nginx_test.conf

啓動命令：

[root@localhost conf]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx_test.conf

-c參數表示加載指定的配置文件，後面跟的是文件路徑

2.在http模塊下添加upstream配置

 upstream tomcat { server localhost:8080; # 對應server下location中添加的 proxy_pass } upstream ApprPhD { server 192.168.0.1XX:3030; }

 

server {
       listen   80;
       server_name  hanmk.com;
       location / {
       root /tmp/data/;
       autoindex on;
}
}
    server {
        listen    80 default_server;
        server_name demo.com ;
        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        # location / {
        #    root   html;
        #   index  index.html index.htm;
        # }

        location / {
        proxy_pass http://tomcat;   # 對應upstream爲tomcat，訪問本地tomcat
        }

        #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   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;
        #}

       location /jenkins {            
              proxy_pass  http://tomcat;  #對應upstream爲tomcat，訪問本地tomcat中部署的jenkins

              proxy_set_header        Host $host;
              proxy_set_header        X-Real-IP $remote_addr;  #獲取真實ip

              proxy_redirect          off;
       }
       location /ApprPhD {          
              proxy_pass http://ApprPhD;  # 對應upstream爲ApprPhD，訪問1XX服務器部署的ApprPhd
              proxy_set_header        Host $host;
              proxy_set_header        X-Real-IP $remote_addr;  #獲取真實ip

       }
