epel是一種yum倉庫，里面提供了更多、更豐富linux軟件，但是，它不是默認(rèn)yum倉庫，我們需要手工添加這個yum源。

添加epel源

然后，找到fedora-epel,

在列表里找到：6server，(這里指的是linux的發(fā)行版，具體，按照自己的情況來，是5.X,就找5，是6.X，就找6,比如，是6.Xserver系列等，就找6server)。

繼續(xù)根據(jù)自己的安裝發(fā)行版選擇，是i386還是X86_64，

我這里 選擇的是X86_64,點(diǎn)擊鏈接，就進(jìn)入了：

接下來會列出很多軟件，用瀏覽器搜一下epel，會找到一個epel-release-6-8.noarch.rpm

復(fù)制該軟件包地址，軟后使用wget進(jìn)行下載

下載完畢后進(jìn)行安裝

[root@localhost?~]#?yum?localinstall??epel-release-6-8.noarch.rpm

安裝完畢，導(dǎo)入gpg-key

[root@localhost?~]#?rpm?--import?/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[root@localhost?~]#?yum?clean?all

[root@localhost?~]#?yum?makecache ??可以看到，epel源已經(jīng)加進(jìn)來了。

[root@localhost?~]#?yum?install?lrzsz

通過yum安裝nginx

1.安裝nginx源

2.安裝nginx

Yum install nginx

Service nginx start ? 啟動nginx

3.然后進(jìn)入瀏覽器，輸入http://ip/測試，如果看到nginx說明安裝成功！

腳本安裝MySQL服務(wù)端

環(huán)境：Centos6.5 ? ? ?mysql: 5.6.20#!/bin/bash

運(yùn)行完以上腳本后需手動運(yùn)行一下以下命令：

source/etc/profile

shell腳本監(jiān)控網(wǎng)站頁面

使用shell腳本寫一個監(jiān)控。通過curl一個固定頁面的200狀態(tài)碼，如果是200，就說網(wǎng)站是正常的,如果不是200就自動重啟網(wǎng)站，然后發(fā)郵件到QQ郵箱。自己在上QQ的同時，通過微信也可以收到報警，不但可以收到報警，還可以解決問題。基本上也可以解決web的故障。#!?/bin/bash
