检查MySQL数据库服务器的shell脚本
【导读】
某著名电子商务公司的同事，编写的shell脚本，用于获得数据库服务器的数据库性能和配置，以及服务器负载LOAD等信息。shell脚本较长，也对shell脚本做了部分修改，同时为使技术朋友们更容易理解和使用，添加相关的文字和图片描述作为手册。
n Shell代码的描述
1. 功能描述
执行shell命令：sh Get_Local_Kpi.sh –help，能显示相关信息，如图1-1：
图1-1
可以为脚本Get_local_skpi指定参数的方式，把指定结果输出到指定的文件，需要检查的VIP地址，检查某项特定的信息，例如：
图1-2
2. 配置文件
Get_Local_Kpi.sh需要读取一个数据库访问的账号密码配置文件，则可能修改代码中的二个地方：
(1). 密码配置文件存放的路径：CONF_DIR=/home/mysqldata/conf
(2). 密码文件头部分：PASS_FILE=”$CONF_DIR”/.mysql_info.”$MY_PORT”
(3). 脚本考虑了一台主机部署多个实例的生产环境，为此你只要执行的时候带上参数 –port=3306的格式即可，若是没有指定此参数则默认赋值为3306
3. 软件安装
Get_Local_Kpi.sh使用了iostat命令工具，若是服务器没有安装软件，则脚本程序会自动通过yum方式帮你安装，但是你的服务器没有配置yum源的话，则需要手工下载软件包：sysstat.x86_64，并且手工安装，软件rpm包下载地址：
http://rpm.pbone.net/index.php3/stat/3/srodzaj/2/search/sysstat-7.0.2-3.el5.src.rpm
4. 脚本缺点及优点
脚本实现部分信息收集的功能，并且shell脚本函数化的方式编写，但是没有完全抽象起来，导致代码较长，对于一些没有条件的技术朋友们，可以借鉴，以及继续添加相关功能。
