需求:访问 log.linuxidc.com/q.gif 成功,其他路径则返回 404,且 404 不记录日志

第一步,配置 nginx rewrite
1. 配置 nginx rewrite
 server {
    listen      8000;
    server_name log.linuxidc.com;
    #index q.gif;
    root /app/data/qm_log;
     
# 如果 url 不是 q.gif,则返回 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;
}

2. 重启 nginx
/etc/init.d/nginx restart

3. 测试访问
访问正确路径
curl http://log.linuxidc.com/q.gif

日志:
12 192.168.1.11 – – [31/May/2016:13:56:47 +0800] “GET /q.gif HTTP/1.1” 200 43 “-” “Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.75 Safari/537.36” – 968 1464674207.162 7 0.000
192.168.1.11 – – [31/May/2016:13:56:47 +0800] “GET /q.gif HTTP/1.1” 304 0 “-” “Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.75 Safari/537.36” – 1048 1464674207.736 8 0.000

访问错误路径:
curl http://log.linuxidc.com/c.gif

日志:
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

第二步,nginx 404 不记录日志
1. 下载模块
地址:https://github.com/cfsego/ngx_log_if

2. 用法样例:
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. 解压下载文件
cd /tmp/soft/
unzip ngx_log_if-master.zip

4. 重新编译 nginx,不覆盖编译
cd /tmp/soft/nginx-1.9.14
 ./configure  \
–prefix=/app/local/nginx \
–pid-path=/app/local/nginx \
–user=nginx \
–group=nginx \
–with-threads \
–with-file-aio \
–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

备份原文件及拷贝新生成文件:
mv /app/local/nginx/sbin/nginx /app/local/nginx/sbin/nginx.bak
 cp ./objs/nginx /app/local/nginx/sbin/

5. 查看模块
# /app/local/nginx/sbin/nginx -V
nginx version: nginx/1.9.14
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) 
built with OpenSSL 1.0.2 22 Jan 2015
TLS SNI support enabled
configure arguments: –prefix=/app/local/nginx –pid-path=/app/local/nginx –user=nginx –group=nginx –with-threads –with-file-aio –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

新的模块以及生效

6. 增加 ninx 404 状态不记录日志
server {
    listen      8000;
    server_name log.linuxidc.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. 重启 nginx 进程

/etc/init.d/nginx restart

8. 再次访问错误路径,发现 404 以及不记录

tailf /app/data/log/nginx/access.log
