rsync那点事

报错信息:

# rsync -rav -e 'ssh -p 36000' /tmp/test/ www@192.168.0.183:/tmp/test/
protocol version mismatch -- is your shell clean?
(see the rsync man page for an explanation)

问题分析：同步用户www没有登录权限

# grep www /etc/passwd
www:x:300:300::/home/www:/sbin/nologin

解决：将www用户改为可登录用户

# grep www /etc/passwd
www:x:300:300::/home/www:/bin/bash
