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yum倉庫，我們需要手工添加這個yum源。

添加epel源

參考：http://freeloda.blog.51cto.com/2033581/1260824?

這里使用搜狐的鏡像，http://mirrors.sohu.com

然后，找到fedora-epel,

http://mirrors.sohu.com/fedora-epel/

在列表里找到：6server，（這里指的是linux的發行版，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）。

接著，從鏈接?http://mirrors.sohu.com/fedora-epel/6Server/?進入，

繼續根據自己的安裝發行版選擇，是i386還是X86_64，

我這里 選擇的是X86_64,點擊鏈接，就進入了：

http://mirrors.sohu.com/fedora-epel/6Server/x86_64/

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

復制該軟件包地址，軟后使用wget進行下載

[root@localhost?~]#?wget?http://mirrors.sohu.com/fedora-epel/6Server/x86_64/epel-release-6-8.noarch.rpm

下載完畢后進行安裝

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

安裝完畢，導入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源已經加進來了。

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

通過yum安裝nginx

1.安裝nginx源

rpm -ivh?http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

2.安裝nginx

? ? Yum install nginx

? ? Service nginx start ? 啟動nginx

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

腳本安裝MySQL服務端

環境：Centos6.5 ? ? ?mysql: 5.6.20

#!/bin/bash #?Script?Name:?One-key?Automatic?Install?MySQL?serverMYSQL_USER_ROOT_PASSWORD="redhat" CMAKE_INSTALL_PREFIX="/usr/local/mysql" MYSQL_DATADIR="/wwwroot/data" DEFAULT_CHARSET="utf8" DEFAULT_COLLATION="utf8_general_ci"echo?-n?"--Installing?related?software..." yum?-y?install?gcc?gcc-c++?make?cmake?bison?ncurses-devel?unzip?wget?perl?>?/dev/null?2>&1?&&?echo?"Completed!"echo?-n?"--Installing?mysql-server..."

運行完以上腳本后需手動運行一下以下命令：

source?/etc/profile

shell腳本監控網站頁面

使用shell腳本寫一個監控。通過curl一個固定頁面的200狀態碼，如果是200，就說網站是正常的,如果不是200就自動重啟網站，然后發郵件到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。
