模拟均衡負載環境: 一台ubuntu15.04做Nginx分發伺服器(192.168.0.101),兩台window2008做Apache web伺服器(192.168.0.15、192.168.0.26)
1、部署Nginx分發伺服器(192.168.0.101)
1)、在ubuntu15.04伺服器上安裝Nginx服務
下載下傳完成後解壓縮到目錄,執行 ./configure,如果無法完成,按照錯誤提示安裝pcre、zlib
numbgui@numbgui:/home/numbgui/Public/nginx-.$ sudo apt-get install libpcre3 libpcre3-dev
numbgui@numbgui:/home/numbgui/Public/nginx-.$ sudo apt-get install zlib1g-dev
執行完成後重新執行 ./configure 來檢測你的安裝平台的目标特征
numbgui@numbgui:/home/numbgui/Public/nginx-.$ sudo ./confugure
檢測通過沒有問題之後執行,make操作
numbgui@numbgui:/home/numbgui/Public/nginx-.$ sudo make
ps: make是用來編譯的,它從Makefile中讀取指令,然後編譯
編譯完成會後執行make install 安裝
numbgui@numbgui:/home/numbgui/Public/nginx-.$ sudo make install
到這裡Nginx服務在ubuntu15.04中已經安裝完成
2)、啟動Nginx服務
啟動Nginx服務
numbgui@numbgui:/home/numbgui$/usr/local/nginx/sbin/nginx -s reload
顯示如下界面表示啟動成功

如果啟動Nginx服務提示是 :丢失nginx.pid
執行以下語句可以解決:
numbgui@numbgui:/home/numbgui$ sudo /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
3)、配置Nginx均很負載(簡單模拟)
編輯/usr/local/nginx/conf/nginx.conf 配置檔案,如下
#user nobody;
worker_processes ;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections ;
}
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 ;
#gzip on;
#這裡配置均很負載的服務位址,我這裡配置的為兩台win2008下的apache web服務,均在80端口下,位址後面的參數:weight--輪詢幾率
upstream apache{
server .: weight= max_fails= fail_timeout=s;
server .: weight= max_fails= fail_timeout=s;
}
server {
listen ;
#這裡server_name 配置上面 upstream配置的名字(這裡為apache)
server_name apache;
#charset koi8-r;
#access_log logs/host.access.log main;
#location / {
# root html;
# index index.html index.htm;
#}
location / {
#http://後面與的參數與server_name相同(這裡為apache)
proxy_pass http://apache;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page /x.html;
location = /x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# 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$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
配置完成之後重新開機 nginx 服務
numbgui@numbgui:/usr/local/nginx/conf$ sudo ./nginx -s reload
2、部署window2008 Apache web服務(192.168.0.15、192.168.0.26)
關于apache服務的部署,這裡不再贅述,如有疑問請自行查詢相關資料
即可完成簡單均很負載配置;
效果如下:
ps: 通路192.168.0.101 Nginx伺服器,通過輪詢的方式計算并轉發給26或者15伺服器的apache web服務;
