4. Nginx配置文件二及虛擬主機配置

#這裏爲後端服務器wugk應用集羣配置，根據後端實際狀況修改便可，tdt_wugk爲負載均衡名稱，能夠任意指定（輪循的方式）

#但必須跟vhosts.conf虛擬主機的pass段一致，不然不能轉發後端的請求。weight配置權重，在fail_timeout內檢查max_fails次數，失敗則剔除均衡。

upstream tdt_wugk {

server   127.0.0.1:8080 weight=1 max_fails=2 fail_timeout=30s;

server   127.0.0.1:8081 weight=1 max_fails=2 fail_timeout=30s;

}

   #虛擬主機配置

server {

#偵聽80端口

        listen       80;

        #定義使用www.wuguangke.cn訪問

        server_name  www.wuguangke.cn;

        #設定本虛擬主機的訪問日誌

        access_log  logs/access.log  main;

root   /data/webapps/wugk;  #定義服務器的默認網站根目錄位置

        index index.php index.html index.htm;   #定義首頁索引文件的名稱

        #默認請求

        location ~ /{

          root   /data/www/wugk;      #定義服務器的默認網站根目錄位置

          index index.php index.html index.htm;   #定義首頁索引文件的名稱

          #如下是一些反向代理的配置.

  proxy_next_upstream http_502 http_504 error timeout invalid_header;

  #若是後端的服務器返回502、504、執行超時等錯誤，自動將請求轉發到upstream負載均衡池中的另外一臺服務器，實現故障轉移。

          proxy_redirect off;

          #後端的Web服務器能夠經過X-Forwarded-For獲取用戶真實IP

          proxy_set_header Host $host;

          proxy_set_header X-Real-IP $remote_addr;

          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

   proxy_pass  http://tdt_wugk;     #請求轉向後端定義的均衡模塊

       }

   

        # 定義錯誤提示頁面

error_page   500 502 503 504 /50x.html;  

            location = /50x.html {

            root   html;

        }

#配置Nginx動靜分離，定義的靜態頁面直接從Nginx發佈目錄讀取。

location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$

{

root /data/www/wugk;

#expires定義用戶瀏覽器緩存的時間爲3天，若是靜態頁面不常更新，能夠設置更長，這樣能夠節省帶寬和緩解服務器的壓力。

expires      3d;

}

        #PHP腳本請求所有轉發到 FastCGI處理. 使用FastCGI默認配置.

        location ~ \.php$ {

            root /root;

            fastcgi_pass 127.0.0.1:9000;

            fastcgi_index index.php;

            fastcgi_param SCRIPT_FILENAME /data/www/wugk$fastcgi_script_name;

            include fastcgi_params;

        }

        #設定查看Nginx狀態的地址

        location /NginxStatus {

            stub_status  on;

        }

     }

}

 

 

實例一：配置一個簡單的頁面

1. grep空白行和註釋行

# cd /usr/local/nginx/

# grep -v "#" nginx.conf | grep -v "^$" >> nginx.conf.bak

# mv nginx.conf.bak nginx.conf

1. 配置一個頁面

user nginx nginx;
worker_processes  1;

error_log logs/error.log info;
pid logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    tcp_nopush     on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  www.doudou0826.com localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /404.html;
        location = /50*.html {
            root   /data/www;

        }
    }
}

測試：

# /usr/local/nginx/sbin/nginx -t

# /usr/local/nginx/sbin/nginx -s reload

# curl 192.168.119.145
It's Works!

 

# tail -n 100 /usr/local/nginx/logs/access.log

 

實例二：配置一個簡單的虛擬主機

進入到主頁目錄下，創建兩個目錄A、B。分別在A、B目錄下創建本身的主頁

# cd /usr/local/nginx/html/

# mkdir A B

# cp index.html a/

# cp index.html b/

# cat ./a/index.html
A site ! It's Works!
# cat ./b/index.html
B site ! It's Works!

 

修改配置文件爲：

user nginx nginx;
worker_processes  1;

error_log logs/error.log info;
pid logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    tcp_nopush     on;
    keepalive_timeout  65;

server {
listen 80;
server_name www.doudou0826a.com;
location / {
root html/a;
index index.html index.htm;
}
}
        server {
                listen 80;
                server_name www.doudou0826b.com;
                location / {
                        root    html/b;
                        index   index.html index.htm;
         }
}
}

 

測試：

# /usr/local/nginx/sbin/nginx -t

# /usr/local/nginx/sbin/nginx -s reload

訪問以前須要修改本地主機的hosts文件，不然沒法用域名訪問

# curl www.doudou0826a.com
> A site ! It's Works!

# curl www.doudou0826b.com
B site ! It's Works!

實例三：設定查看Nginx狀態的地址

在server裏面加入

 location /NginxStatus {
                        stub_status     on;
                }

 

例如：

server {
                listen 80;
                server_name www.doudou0826b.com;
                location / {
                        root    html/b;
                        index   index.html index.htm;
                }
                location /NginxStatus {
                        stub_status     on;
                }
        }

 

測試：

# /usr/local/nginx/sbin/nginx -t

# /usr/local/nginx/sbin/nginx -s reload

# curl www.doudou0826b.com/NginxStatusActive connections: 2 server accepts handled requests 45 45 73 Reading: 0 Writing: 1 Waiting: 1
