nginx實現unigui群集

nginx實現unigui群集

在筆者寫此文的時候，UNIGUI1.50.x的版本已經發布，其提供的HyperServer已經支持群集。

有網友還專門為此做了群集方面的測試：

從上圖可以看出：群集總共開了51個UNIGUI服務程式，總共有13357個客戶端(sessions)連接，並且如此多的連接還操作正常。足可見HyperServer的強大。

HyperServer雖然好用，卻只有UNIGUI最新版本才提供。

而NGINX做群集，卻可以適用於所有UNIGUI的版本。

NGINX支持多種群集的方式，此處使用ip_hash實現UNIGUI群集。

1）下載NGINX FOR WINDOWS版本

http://nginx.org/en/download.html

2) 在服務器上開啟多個unigui服務程式，每個程式須綁定不同的PORT。

3）配置nginx.conf

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#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 0;
keepalive_timeout 65;

#gzip on;

upstream cxg {
ip_hash;
server 47.106.93.126:7777;
server 47.106.93.126:9998;
}

server {
listen 9999;
server_name 47.106.93.126;

 

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.html index.htm;
proxy_pass http://cxg;
}

#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;
#}
}

# 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;
# }
#}

}

4）開啟nginx

start nginx

nginx -s reload

5) 瀏覽器打開：http://47.106.93.126:9999/

即可正常訪問
