我們的業務使用了nginx、mysql、php、和tomcat，寫了一個自動化安裝這些軟體的指令碼，雖然網上類似的自動安裝指令碼很多，但這個是自己寫的，特此mark一下，希望能給別人一些參考，同時也灰常歡迎看到的朋友們提些改進意見。話不多說，直接上指令碼。

#!/bin/sh
    alias echo='echo -e'
    ###判斷系統，此指令碼只適用於64位系統
    machine=`uname -m`
    if [ $machine != x86_64 ] ;then
       echo "\e[1;31m \nyour system is 32bit,but this script is only run on 64bit !\n \e[0m"
 

       exit -1
    fi 
    ###建立儲存下載檔案的目錄
    mkdir /usr/local/src/auto_install &> /dev/null
    source_dir=/usr/local/src/auto_install
    ###定義一個互動式的選擇提示
function interact {
    echo "Please input \"yes\" or \"no\""
    read choice
    case "$choice" in
       no)
          exit 0;;
       yes)
          echo
 
;;
        *)
      echo "\e[1;31mInput Errot! \e[0m"
          exit -1;;
    esac
}
     ### 定義一個函式檢查上一條命令的執行狀態
function check {
   if [ $? -ne 0 ];then
        echo  "\e[1;31m\n the last commond exec failed,please check it !\e[0m \n"
    sleep 1
    exit -1
   fi
}
### 定義下載各軟體的函式（此處我隱藏了我們的下載地址，需各位自行設定下載地址）

       ### 定義mysql安裝函式###
function mysql_install {

        ######判斷結束######

    ###檢查是否有系統自帶的mysql-lib-5.1，有則刪除
    rpm -qa|grep -i -e "mysql.*5\.1.*"|xargs rpm -e --nodeps 2> /dev/null
        ###互動式選擇mysql安裝路徑
    echo  "\e[1;31m where do you want to install mysql(default is /usr/local/mysql)\e[0m"

    sed -i -e "/^basedir*=$/i\basedir=$mybasedir" -e "/^datadir*=$/i\datadir=$mydatadir" /etc/init.d/mysql
    sed -i -e '/^basedir*=$/d' -e '/^datadir*=$/d' /etc/init.d/mysql   
       ###初始化資料庫
    echo "\e[1;32m\n ---initialize mysql database---\e[0m"
    sleep 1
    chown -R mysql $mydatadir $mybasedir >/dev/null 2>&1
    $mybasedir/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql --basedir=$mybasedir --datadir=$mydatadir
    check;
       ###將basedir/bin/新增到PATH
    echo "PATH=$PATH:$mybasedir/bin" >> /etc/profile
    export PATH=$PATH:$mybasedir/bin

    echo "\e[1;32m install mysql success,you can run \"service mysql start\" to start the mysql \n do not forget to set a password for mysql \e[0m"
