對shell不是很熟悉， 斷斷續續的寫了一個晚上，終於搞定

使用方式，root使用者解壓到某個目錄下， 執行 ./autoinstall_mysql_5.6.sh 即可， 後面如果不加引數， 則預設安裝3306埠的例項，可以加埠引數改變預設埠。

比如 ./autoinstall_mysql_5.6.sh 3307

指令碼會新增環境變數 $MYSQL_HOME指向二進位制可執行程式的目錄

指令碼會同時在home下新建3個sh，分別用於啟動mysql，停止mysql和本機OS免登mysql

機器需要安裝yum和wget,perl，用於下載二進位制可執行檔案。

yum install -y wget

yum install -y perl

yum install -y libaio

如果是要裝mysql5.7的話，可能需要調整一下指令碼， 修改裡面的安裝檔名，還有5.7的scripts目錄已經遷移到了bin目錄，需要做一些調整。

不過目前看5.6還是主流。

指令碼預設會在/mysql/server下建立二進位制執行檔案

在/mysql/下建立例項資料/日誌檔案

主要的指令碼內容如下

autoinstall_mysql_5.6.sh

#port
port=3306
if [ $# -gt 0 ]; then
	port=$1
fi

echo 'install mysql service on port:'${port}

yum install -y wget
yum install -y perl
yum install -y libaio
