开机自动启动rsync

1. 扔脚本进去/etc/init.d/

2. 授权
chmod +x rsync

3. 一旦抛出:binsh^M错误就执行编码改写
设置dos统一编码
(请看rsync脚本抛出binsh^M bad interpreter文档)

4. 添加到服务
chkconfig --add ningx


5. 随机启动脚本带动rsync开机启动
chkconfig --level 2345 rsync on

 

 

---

 

执行脚本时发现如下错误：
/bin/sh^M: bad interpreter: 没有那个文件或目录

错误分析:
因为操作系统是windows，我在windows下编辑的脚本，所以有可能有不可见字符。
脚本文件是DOS格式的, 即每一行的行尾以\n\r来标识, 其ASCII码分别是0x0D, 0x0A.

可以有很多种办法看这个文件是DOS格式的还是UNIX格式的, 还是MAC格式的

解决方法：
vim filename
然后用命令
:set ff? #可以看到dos或unix的字样. 如果的确是dos格式的。


然后用
:set ff=unix #把它强制为unix格式的, 然后存盘退出。
再次运行脚本。
