Nginx负载均衡

发布时间:2024年01月03日

很久以前配置过,留档:

nginx.conf 文件

#user  nobody;
worker_processes  4;

# This default error log path is compiled-in to make sure configuration parsing
# errors are logged somewhere, especially during unattended boot when stderr
# isn't normally logged anywhere. This path will be touched on every nginx
# start regardless of error log location configured here. See
# https://trac.nginx.org/nginx/ticket/147 for more info. 
#
#error_log  /var/log/nginx/error.log;
#

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       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  logs/access.log  main;

    #sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  65;

    #gzip  on;
# add for nginx proxy
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

#    include /usr/local/etc/nginx/mime.types;

    include airoot.org.conf;
#    server {
#        listen       80;



        # 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;
        #}
    #}


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

其实主要就是在nginx的配置文件中,在http的后面 ,server的前面,加上这一句:include airoot.org.conf;

然后创建airoot.org.conf文件:

upstream ww3.airoot.org{
    ip_hash;
    server 192.168.0.9:5000;
    server 192.168.0.9:5001;
}

server {
    listen 5000;

    # optional ssl configuration

    #listen 443 ssl;
    #ssl_certificate /path/to/ssl/pem_file;
    #ssl_certificate_key /path/to/ssl/certificate_key;

    # end of optional ssl configuration

    server_name  ww2.airoot.org;

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

    location / {
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $host:$server_port;
        proxy_set_header X-Forwarded-Port $server_port;
	proxy_set_header Host $host:$server_port;
        client_max_body_size    10m;
        client_body_buffer_size 128k;
        proxy_connect_timeout   60s;
        proxy_send_timeout      90s;
        proxy_read_timeout      90s;
        proxy_buffering         off;
        proxy_temp_file_write_size 64k;
        proxy_pass http://ww3.airoot.org;
        proxy_redirect          off;
    }
}

多机代理的时候,若有问题,则加上这句proxy_set_header Host $host:$server_port;
