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
