查看/usr/local/nginx/conf/nginx.conf的日志格式：

[root@DasonCheng ~]# grep -A2 log_format /usr/local/nginx/conf/nginx.conf log_format custom \'$remote_addr $http_x_forwarded_for [$time_local]\' \' $host "$request_uri" $status\' \' "$http_referer" "$http_user_agent"\'; //Nginx里面";"才表示换行

除了在主配置文件nginx.conf里定义日志格式外，还需要在虚拟主机配置文件中增加：

access_log /tmp/1.log custom; //这里的custom就是在nginx.conf中定义的日志格式名字 -t && -s reload curl -x127.0.0.1:80 test.com -I cat /tmp/1.log

测试：

[root@DasonCheng tmp]# vim /usr/local/nginx/conf/vhost/test.com.conf access_log /tmp/1.log custom; //添加这一行配置； …… [root@DasonCheng tmp]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@DasonCheng tmp]# /usr/local/nginx/sbin/nginx -s reload …… [root@DasonCheng tmp]# curl -x127.0.0.1:80 test.com/admin/1.php File not found.
