Nginx rwrite and add Nginx modules that do not record specific statuses

Requirement: log.bkjia.com/q.gif is successfully accessed, 404 is returned for other paths, and 404 is not logged.

Step 1: Configure nginx rewrite
1. Configure nginx rewrite
Server {
Listen 8000;
Server_name log.bkjia.com;
# Index q.gif;
Root/app/data/qm_log;

If urlis not q.gif, 404 is returned.
If ($ uri !~ ^/Q.gif ){
Return 404;
}
Location ~ *. * \. (Jpg | jpeg | gif | png | bmp) $ {
Expires 30d;
Break;
}
Error_log/app/data/log/nginx/www. error. log;
}

2. Restart nginx
/Etc/init. d/nginx restart

3. Test Access
Access to the correct path
Curl http://log.bkjia.com/q.gif

Logs:

Curl http://log.bkjia.com/c.gif

Logs:
192.168.1.11--[31/May/2016: 13: 48: 33 + 0800] "GET/HTTP/1.1" 404 564 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.75 Safari/537.36 "-1068 1464673713.147 8 0.000

Step 2: nginx 404 does not record logs
1. Download Module
Address: https://github.com/cfsego/ngx_log_if

2. Usage example:
Server {
Access_log_bypass_if ($ status = 400 );
Access_log_bypass_if ($ host ~ * 'Nolog. com ');
Access_log_bypass_if ($ uri = 'status. nginx') and;
Access_log_bypass_if ($ status = 200 );
}
In the case, nginx will not write access log when the status code is 400, or when the host is 'nolog. com ', or when the uri is 'status. nginx 'and the status code is 200.
However, if you define them both in the blocks in the father child relationship, the child block will not inherit and merge the configuration in parent block, of course. FOr example:
Server {
Access_log_bypass_if ($ status = 400 );
Location /{
Access_log_bypass_if ($ host ~ * 'Nolog. com ');
}
}

3. decompress the downloaded file
Cd/tmp/soft/
Unzip ngx_log_if-master.zip

4. recompile nginx without Overwriting
Cd/tmp/soft/nginx-1.9.14
./Configure \
-- Prefix =/app/local/nginx \
-- Pid-path =/app/local/nginx \
-- User = nginx \
-- Group = nginx \
-- With-threads \

With-http_ssl_module \
With-http_v2_module \
With-http_addition_module \
With-http_sub_module \
With-http_dav_module \
With-http_flv_module \
With-http_mp4_module \
With-http_perl_module \
-- With-mail \
With-http_gzip_static_module \
With-http_auth_request_module \
With-http_random_index_module \
With-http_secure_link_module \
With-http_degradation_module \
With-http_slice_module \
With-http_stub_status_module \
With-http_perl_module \
-- With-zlib =/tmp/soft/zlib-1.2.8 \
-- With-stream \
With-stream_ssl_module \
-- With-pcre =/tmp/soft/pcre-8.37 \
-- With-openssl =/tmp/soft/openssl-1.0.2 \
-- With-libatomic \
-- Add-module =/tmp/soft/ngx_log_if-master
Make

Back up the original file and copy the new file:
Mv/app/local/nginx/sbin/nginx. bak
Cp./objs/nginx/app/local/nginx/sbin/

5. view the module
#/App/local/nginx/sbin/nginx-V

New modules and effective modules

6. added the n1_404 status to keep logs.
Server {
Listen 8000;
Server_name log.bkjia.com;
# Index q.gif;
Root/app/data/qm_log;
Access_log_bypass_if ($ status = 404 );

If ($ uri !~ ^/Q.gif ){
Return 404;
}

Location ~ *. * \. (Jpg | jpeg | gif | png | bmp) $ {
Expires 30d;
Break;
}

Error_log/app/data/log/nginx/www. error. log;
}

7. Restart the nginx Process

/Etc/init. d/nginx restart

8. Access the Error Path again and find 404 or not recorded

Tailf/app/data/log/nginx/access. log
