Ngnix upgrade and modify configurations

First Download Nginx: execute wget http://nginx.org/download/nginx-0.8.54.tar.gz



Decompress and enter the Directory

Tar zxvf nginx-0.8.54.tar.gz

Run again./configure -- user = www -- group = www -- prefix =/usr/local/nginx -- with-http_stub_status_module -- with-http_ssl_module -- with-http_gzip_static_module.

Then make, but do not make install

After compilation, there is an nginx execution file under the objs directory.

Back up old nginx files

Mv/usr/local/nginx/sbin/nginx. old

Run cp objs/nginx/usr/local/nginx/sbin/nginx after converting nginx cp under the new objs to sbin.

Run the/usr/local/nginx/sbin/nginx-t test to check whether there is any problem.

Run make upgrade again.

Run:/usr/local/nginx/sbin/nginx-V to display the nginx version and compiled parameters.

Upgrade complete!

404 configuration:

1.create the secret 404.html page

2. change nginx. conf and add fastcgi_intercept_errors on in the http definition area;

3. change nginx. conf (or a separate website configuration file, for example, the site configuration file under nginx-> sites-enabled)

Add: error_page 404 =/404.html or error_page 404 = http://www.xxx.com/404.html in the server region

4. reload the configuration file after modification, without restarting

#502 and other errors can be configured in the same way.

Error_page 500 502 503 504 =/50x.html;

Smooth configuration modification:

/Usr/local/nginx/sbin/nginx-t

/Usr/local/nginx/sbin/nginx-s reload

The first statement is to check whether the configuration file is correct and the correct information:

The configuration file/usr/local/nginx/conf/nginx. conf syntax is OK

The configuration file/usr/local/nginx/conf/nginx. conf was tested successfully
