常见python脚本

bind+mysql一键安装脚本

上次搭建完DNS服务器之后,发现再重新安装一台的话要重复相同的步骤,好麻烦。于是想着自己也写个脚本方便安装，然后就写了个非常粗糙的脚本。后期有时间再修改吧。暂时先用着。
环境：
系统：Centos6.5
需要先安装mysql，编译或者直接yum源安装 yum install -y mysql-server mysql mysql-devel

#!/bin/bash
bind_url="ftp://ftp.isc.org/isc/bind9/cur/9.9/bind-9.9.6.tar.gz"
mysql_bind="http://nchc.dl.sourceforge.net/project/mysql-bind/mysql-bind/mysql-bind-0.2%20src/mysql-bind.tar.gz"
base_dir="/opt/bind_install"
bind_filename=`basename ${bind_url}`
mysql_filename=`basename ${mysql_bind}`
# Download files
function download_files(){
    if [ ! -d "$base_dir" ]; then
        mkdir $base_dir
    fi
    cd $base_dir
    if [ ! -f "$bind_filename"  ];then
        if  wget ${bind_url}; then
