Apache is one of the most popular web servers serving more than 30% percent of the websites. It is a free and open-source HTTP server. It comes packaged with tons of tools and features to run applications securely and with ease.
This tutorial describes how to set up SSL secure websites on the Apache Webserver.
NOTE: This tutorial is written and tested for Debian 9, 10, and 11 and Ubuntu 20.04.
First thing you want to do before installing MTDb is to create a new database on your mysql server. If you already know how to do this/or have already created one just skip to the next step.
Your host will most likely be running phpMyAdmin as mysql manager, if that's the case here's a step by step guide (if not the proccess will be very similar on other managers).
前段时间接了个小活，要求是在nginx层面实现简繁体转换。一般正常的简繁转换都会放在前端页面的JS来实现，为何会要求在nginx层面实现呢？问过客户后，发现是要反向代理其它网站。具体的用途我也没好意思深究，我还是只管好好实现功能就完了。
真正的懒癌晚期患者(缺钱也治不了），懒到不想给服务器做安全加固，就靠着复杂的数字字母混合16位密码保障着。前段时间看了看/var/log/secure文件，吓到了，好几个IP登录ssh失败，有近十万次之多。网上的闲人是真不少啊，网站没几个正经访客，各种扫描的倒是每天都有近千IP。还是得出手干活啊，不然哪天真攻破了服务器，也对不起自己的专业了。
手里服务器大部分centos7，只有两台debian9，方案上自然选择fail2ban+firewall了。
原理：
通过定时脚本检查系统登录失败日志/var/log/secure,统计每个IP失败登录次数，当统计到失败次数大于阀值时，将IP加入系统屏蔽名单/etc/hosts.deny中。
