Nginx main configuration parameters detailed, nginx configuration website

Install Nginx in A.linux. The post address is: http://www.cnblogs.com/cindy-cindy/p/6847499.html

B. When the Nginx installation is complete, there will be a corresponding installation directory, the installation directory of the NGINX.CONFG is nginx main configuration file, nginx main configuration file is divided into 4 parts, main (global configuration), server (host configuration), upstream ( Load balancer server settings) and location (URL matches settings at specific locations), the four relationships are: Server Inherits Main,location inheritance Server,upstream does not inherit other settings or inherit.

C.nginx is a proxy server, under normal circumstances, the site can not be deployed under Nginx, such as Java-developed Javaweb program, we deployed under Tomcat, and then use the Nginx Proxy to point to Tomcat.

3.Nginx Proxy website

A. I deployed a Javaweb project under Tomcat, with the server IP of Tomcat installed: 192.168.37.136, the access address of the deployed project under Tomcat is: http://192.168.37.136:8080/lywh/

B. I installed the 192.168.37.133 under the IP server.

C. How about using the Nginx proxy for sites deployed under Tomcat? , modify the Nginx configuration file, modify the command: vim/usr/local/nginx/conf/nginx.conf

  1 #user nobody;  2 worker_processes 1;  3 #error_log Logs/error.log;  4 #error_log logs/error.log notice;  5 #error_log Logs/error.log Info; 7 #pid Logs/nginx.pid; Ten events {One worker_connections, and a. http {include mime.types; Default_type applicat Ion/octet-stream; #log_format Main ' $remote _addr-$remote _user [$time _local] "$request" ' # ' $status $ Body_bytes_sent "$http _referer" ' # ' "$http _user_agent" "$http _x_forwarded_for"; #access_log Logs/access.log Main; Sendfile on; #tcp_nopush on; #keepalive_timeout 0; Keepalive_timeout 65; #gzip on;     #配置tomcat的IP地址和访问端口 upstream GW {192.168.37.136:8080 weight=1;   * * * PNS server {Listen, server_name localhost, 42 #charset koi8-r; #access_log logs/host.access.log main; The location/{root HTML; index index.html index.htm; #N Ginx Agent configuration of LOCATION/LYWH {Proxy_pass http://gw/lywh; The HTTP://GW/SHOPAPPAPI; location/cas{Proxy_pass Http://gw/cas-server-webapp-4.0.0/login, location/do c{proxy_pass Http://gw/docs; #error_page 404/404.html;  # REDIRECT Server error pages to the static page/50x.html 500 502 503 504/50x.html; The location of the location =/50x.html {The root html;] The PHP scripts to Apach          E listening on 127.0.0.1:80 # #location ~ \.php$ {# Proxy_pass http://127.0.0.1; 76 #} * * * Pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 79        # #location ~ \.php$ {Bayi # root HTML; Fastcgi_pass 127.0.0.1:90 00; 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; 94} * * Anothe R Virtual host using mix of ip-, name-, and port-based Configuration 98 # #server {80 # Listen 00;101 # Listen somename:8080;102 # server_name somename alias another.alias;103 104 # Locat  Ion/{html;106 # root # index index.html index.htm;107 #}108 #}109 110 111 # HTTPS server112 #113 #server {Listen # 443 ssl;115 # server_name  localhost;116 117 # ssl_certificate cert.pem;118 # ssl_certificate_key cert.key;119 # SSL _session_cache shared:ssl:1m;121 # ssl_session_timeout 5m;122 123 # Ssl_ciphers high:!anull:!        md5;124 # ssl_prefer_server_ciphers on;125 126 # location/{127 # root html;128 # Index index.html index.htm;129 #}130 #}131 132}

D. When you are finished configuring nginx.conf, close the file, execute the command to check the configured file for problems, if it is not a problem, you need to check the configuration for problems

　　　　

E. Check if return OK, the modification file does not have any errors, this time restart Nginx, the command is:/usr/local/nginx/sbin/nginx-s Reload

F. The website after the last visit to the agent, HTTP://192.168.37.133/LYWH,: Indicates that the agent has visited:

　　　　

This note has been written, if you have any questions to discuss with me, I am also learning while writing notes, such as where there are errors, please tell

Finally I wish you a happy New year, go home tomorrow, a smooth journey
