为申威服务器+深度操作系统安装nginx配置负载均衡

需求：在申威服务器上部署NC Cloud集群。使用nginx 为负载均衡。

1、下载当前架构芯片的nginx包到/data/nginx

http://packages.deepin.com/sw6a/pool/main/n/nginx/

2、安装nginx

cd /data/nginx

dpkg -i *.deb

3、添加nginx 用户

useradd nginx

4、修改nginx配置，参考配置如下

worker_processes  auto;

user nginx;

pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.

include /usr/share/nginx/modules/*.conf;



events {

    use epoll;

    worker_connections  20480;

    multi_accept on;

    accept_mutex on;

}



http {

    include       mime.types;

    default_type  application/octet-stream;



    log_format  main  '$remote_addr|$remote_user|[$time_local]|"$request"|'

                      '$status|$body_bytes_sent|$http_host|"$http_referer"|'

                      '"$http_user_agent"|$http_x_forwarded_for|$upstream_cache_status|'

                      '"$upstream_http_content_type"|$request_time|$upstream_response_time|$bytes_sent|$request_length|'

                      '"$upstream_addr"';



    #access_log /tmp/nginx_access.log  main;

    #error_log /tmp/nginx_error.log notice;



    sendfile        on;

    keepalive_timeout  65;



    charset utf-8;

    server_tokens off;

    server_names_hash_bucket_size 128;

    client_header_buffer_size 32k;

    large_client_header_buffers 4 32k;

    client_max_body_size 800m;

    tcp_nopush on;



    underscores_in_headers on;

    client_body_buffer_size 512k;

    proxy_headers_hash_max_size 51200;

    proxy_headers_hash_bucket_size 6400;

    proxy_connect_timeout 5;

    proxy_read_timeout 60;

    proxy_send_timeout 5;

    proxy_buffer_size 16k;

    proxy_buffers 4 64k;

    proxy_busy_buffers_size 128k;

    proxy_temp_file_write_size 128k;

    proxy_temp_path /tmp/nginx_proxy_temp;

    proxy_cache_path /tmp/nginx_proxy_cache levels=1:2 keys_zone=content:20m inactive=1d max_size=100m;

    proxy_cache_path /tmp/nginx_proxy_cache_image levels=1:2 keys_zone=content_image:20m inactive=1d max_size=100m;

    proxy_cache_bypass $http_secret_header;

    proxy_ignore_client_abort on;



    gzip on;

    gzip_min_length 1k;

    gzip_buffers 4 16k;

    gzip_http_version 1.0;

    gzip_comp_level 2;

    gzip_types text/plain application/x-javascript application/javascript text/css;

    gzip_vary on;





upstream nccloud1909 {

    server 10.10.4.142:81    weight=1  max_fails=2  fail_timeout=10;

    server 10.10.4.142:82    weight=1  max_fails=2  fail_timeout=10;

	server 10.10.4.142:83    weight=1  max_fails=2  fail_timeout=10;

	server 10.10.4.142:84    weight=1  max_fails=2  fail_timeout=10;

	server 10.10.4.142:85    weight=1  max_fails=2  fail_timeout=10;

}

    include conf.d/*.conf;





server {

    listen 80;

    server_name 10.10.4.142 default;

    proxy_http_version 1.1;





    location / {

        add_header Access-Control-Allow-Origin *;

        add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';

        add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

        if ($request_method = 'OPTIONS'){

          return 204;

        }

        proxy_set_header X-Forwarded-For $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_http_version 1.1;

        proxy_set_header Upgrade $http_upgrade;

        proxy_set_header X-Forwarded-Host $http_host;

        proxy_set_header Host $http_host;

        proxy_redirect off;

        proxy_pass http://nccloud1909;

    }

}



}

5、启动nginx

service nginx start
