yangl / nginx手机端跳转配置.conf

Last active March 2, 2020 13:19

nginx根据user-agent手机端跳转，nginx rewrite详见：http://seanlook.com/2015/05/17/nginx-location-rewrite/

	location = / {

	if ($http_user_agent ~* "(Android\|iPhone\|iPod\|Symbian\|BlackBerry\|Windows Phone\|Mobile\|J2ME)") {
	rewrite ^ http://m.uxin.com permanent;
	}

	#htpasswd密码生成可用在线工具http://tool.oschina.net/htpasswd，加密方式选Crypt
	auth_basic_user_file /data/soft/nginx/conf/htpasswd;
	auth_basic "please input passwd, or contact YANGL";

yangl / GuavaCache及@Value使用例子.java

Last active January 12, 2017 03:41

guava cache使用例子。。。注意在查询数据库时没有记录的情况，暂时获取CacheLoader.InvalidCacheLoadException异常，或者存放默认数据并标示NoDATA！@value注入static属性时注意要加到其非静态setter方法上即可！

	package com.uxin.starclock.manage.impl;

	import com.alibaba.fastjson.JSON;
	import com.alibaba.fastjson.JSONObject;
	import com.google.common.cache.Cache;
	import com.google.common.cache.CacheBuilder;
	import com.google.common.cache.CacheLoader;
	import com.uxin.starclock.common.Constant;
	import com.uxin.starclock.common.exception.BaseException;
	import com.uxin.starclock.dto.IncallringDto;

yangl / cloudera安装文档.txt

Created April 1, 2016 04:26

cloudera安装文档

	1.各个节点安装必需的包
	yum install -y openssh openssh-clients vim libxslt libaio


	2.配置ssh无密码认证（个人认为可以忽略的步骤）
	（1）修改hosts.allow 将新的IP都加进去
	（2）修改ssh的配置文件允许root登录，再重启ssh服务
	（3）在一台机器上ssh所有机器，获取所有的机器的公钥，再生成自己的ssh-key，无密码登录自己，把.ssh目录打包，传到每个机器上

	3.修改hosts文件
