Nginx related operations

Operation under Windows: 1. Start: C:\ server\ nginx-1.14.2 > start nginx or C:\ server\ nginx-1.14.2 > nginx.exe Note: the first is recommended, and the second will keep your cmd window in execution all the time, and no other command operations can be carried out. 2. Stop: C:\ server\ nginx-1.14.2 > nginx.exe-s stop`` or C:\ server\ nginx-1.14.2 > nginx.exe-s quit Note: stop is to quickly stop nginx and may not save relevant information; quit is to stop nginx in a complete and orderly manner and save relevant information. 3. Reload Nginx: C:\ server\ nginx-1.14.2 > nginx.exe-s reload use this command when the configuration information is changed and you need to reload these configurations. 4. Reopen the log file: C:\ server\ nginx-1.14.2 > nginx.exe-s reopen 5, and view the Nginx version: C:\ server\ nginx-1.14.2 > nginx- v

Nginx reverse proxy path problem

The difference between http://abc.com:8080 and http://abc.com:8080/ writing is as follows: without / location / NginxTest/ {proxy_pass http://abc.com:8080;} with / location / NginxTest/ {proxy_pass http://abc.com:8080/; } the only difference between the above two configurations is whether the path forwarded by proxy_pass is followed by "/". For case 1: (with parameters) if you access url = http://localhost:90/NginxTest/servlet/MyServlet?name=123333333, after being proxied by nginx, the request path will access http://abc.com:8080/NginxTest/servlet/MyServlet?name=123333333. (no parameters) if you access url = http://localhost:90/NginxTest/servlet/MyServlet, the request path will access http://abc.com:8080/NginxTest/servlet/MyServlet after being proxied by nginx. For case 2: if you access url = http://server/NginxTest/test.jsp, after being proxied by nginx, the request path will change to http://proxy_pass/test.jsp and directly access the root resource of server. Access http://localhost:90/NginxTest/NginxTest/NginxTest/servlet/MyServlet, and the request path will not access http://abc.com:8080/NginxTest/servlet/MyServlet until it is proxied by nginx. * * Note: the difference between the above two access paths. Restart the nginx agent successfully after modifying the configuration. **

Nginx address rewriting

Location / NginxTest/ {rewrite ^ / NginxTest/ (. *) $/ $1 break; proxy_pass http://abc.com:8080;} 1. ^ ~ / NginxTest/ is a matching rule that intercepts requests, matches any address that starts with / NginxTest/, and stops searching for rules after the match. 2.rewrite ^ / NginxTest/ (. *) $/ $1 break; means to rewrite the intercepted request, and can only work on the string after the domain name except for the passed parameters, such as http://localhost:90/NginxTest/NginxTest/servlet/MyServlet?name=lovleovlove rewriting, only / NginxTest/NginxTest/servlet/MyServlet rewriting. For example, the access address: http://localhost:90/NginxTest/NginxTest/servlet/MyServlet?name=lovleovlove, the actual access address (rewrite address) is http://ita-1312-0059.synacast.local:8080/NginxTest/servlet/MyServlet?name=lovleovlove, for example, the access address: http://localhost:90/NginxTest/NginxTest/servlet/MyServlet The actual access address (rewrite address) is http://ita-1312-0059.synacast.local:8080/NginxTest/servlet/MyServlet 3.rewrite, followed by a simple regular ^ / NginxTest/ (. *) $/ $1, where $1 represents the first () in the regular, $2 represents the value of the second (), and so on. Break means to stop matching after matching one. Syntax of rewrite: rewrite regex URL [flag] Rewrite is the keyword, regex is the regular expression, URL is the content to be replaced, and [flag] means the mark bit. It has the following values: last: equivalent to the [L] tag of Apache, indicating completion of rewrite break: stop executing the subsequent rewrite instruction set of the current virtual host redirect: return 302 temporary redirection, the address bar will display the jump address permanent: return 301 permanent redirection The address bar displays the address after the jump.
