</pre>場景：在10.17.55,44:7002和10.17.55.46:7003的weblogic 部署一個web工程，準備做負載均衡。在一臺IP：12.17.56.44能訪問到55.44和55.46上web工程的機器做nginx代理伺服器，代理埠為7000，既12.17.56.44:7000能訪問到<span style="font-size:14px;">10.17.55,44:7002或<span style="font-size:14px;">10.17.55.46:7003的web工程，而網際網路有個IP22.18.55.33:7000 可以訪問到，<span style="font-size: 14px;">12.17.56.44:7000，<span style="font-size: 14px;">12.17.56.44</span></span></span></span>這臺伺服器的nginx.conf 內容配置如下：<p></p><p><span style="font-size:14px;"></span></p><pre name="code" class="html">#user nobody; worker_processes auto; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 2048; accept_mutex off; multi_accept on; use epoll; } # load modules compiled as Dynamic Shared Object (DSO) # #dso { # load ngx_http_fastcgi_module.so; # load ngx_http_rewrite_module.so; #} #thread_pool one threads=128 max_queue=0; http { include mime.types; default_type application/octet-stream; #thread_pool one threads=128 max_queue=0; include /etc/nginx/mutnginx/*.conf; #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; access_log off; sendfile on; #tcp_nopush on; sendfile_max_chunk 512k; #keepalive_timeout 0; keepalive_timeout 65; upstream cluster1 { # simple round-robin ip_hash; server 10.17.55,44:7002; server 10.17.55.46:7003; } #gzip on; server { listen 7000; server_name localhost; # 0.99.132.52:700 #check interval=30 #charset koi8-r; #access_log logs/host.access.log main; location / { #aio threads=one; proxy_set_header Host $host:7000; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering off; proxy_pass http://cluster1/; # root html; #index index.html index.htm; } location /status { #check_status; access_log off; allow all; # deny all; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # 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$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
配置檔案中：
include /etc/nginx/mutnginx/*.conf; nginx2.conf配置是為了讓同個網段即12.17.56.*的其他應用能同個代理ip訪問到web工程，其配置如下：
#user nobody; worker_processes auto; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 2048; accept_mutex off; multi_accept on; use epoll; } # load modules compiled as Dynamic Shared Object (DSO) # #dso { # load ngx_http_fastcgi_module.so; # load ngx_http_rewrite_module.so; #} #thread_pool one threads=128 max_queue=0; http { include mime.types; default_type application/octet-stream; #thread_pool one threads=128 max_queue=0; #log_format main '$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; access_log off; sendfile on; #tcp_nopush on; sendfile_max_chunk 512k; #keepalive_timeout 0; keepalive_timeout 65; upstream cluster3 { # simple round-robin ip_hash; server 10.17.55,44:7002; server 10.17.55.46:7003; } #gzip on; server { listen 7000; server_name localhost; # 0.99.132.52:700 #check interval=30 #charset koi8-r; #access_log logs/host.access.log main; location / { #aio threads=one; proxy_set_header Host $host:7000; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering off; proxy_pass http://cluster3/; # root html; #index index.html index.htm; } location /status { #check_status; access_log off; allow all; # deny all; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # 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$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
還有一個nginx3.conf 是為了讓，其他內網ip統一訪問的代理，其配置如下：
其中#user nobody; worker_processes auto; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 2048; accept_mutex off; multi_accept on; use epoll; } # load modules compiled as Dynamic Shared Object (DSO) # #dso { # load ngx_http_fastcgi_module.so; # load ngx_http_rewrite_module.so; #} #thread_pool one threads=128 max_queue=0; http { include mime.types; default_type application/octet-stream; #thread_pool one threads=128 max_queue=0; #log_format main '$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; access_log off; sendfile on; #tcp_nopush on; sendfile_max_chunk 512k; #keepalive_timeout 0; keepalive_timeout 65; upstream cluster2 { # simple round-robin ip_hash; server 10.17.55,44:7002; server 10.17.55.46:7003; } #gzip on; server { listen 7000; server_name localhost; # 0.99.132.52:700 #check interval=30 #charset koi8-r; #access_log logs/host.access.log main; location / { #aio threads=one; proxy_set_header Host $host:5123; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering off; proxy_pass http://cluster2/; # root html; #index index.html index.htm; } location /status { #check_status; access_log off; allow all; # deny all; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # 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; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
proxy_set_header Host $host:5123;#是對映埠，如果12.17.56.44:7000對映IP為102.34.56.44 那麼5123就是對映器7000埠12.17.56.44
