  问题:

  Linux上的SSH无法启动

  报告/var/empty/sshd must be owned by root and not group or world-writable.

  解决办法:

  首先通过物理终端进入到linux上,手工检查ssh发现没运行

  -bash-2.05b# /etc/init.d/sshd status

  sshd is stopped

  手工启动服务,发现报告权限错误。

  -bash-2.05b# /etc/init.d/sshd start

  Starting sshd:/var/empty/sshd must be owned by root and not group or world-writable.

  [FAILED]

  -bash-2.05b#

  使用rpm -V 命令可检查到ssh的软件包正常,但某个目录的属主错误。

  -bash-2.05b# rpm -V openssh-server

  S.5….. c /etc/ssh/sshd_config

  …..U.. /var/empty/sshd

  -bash-2.05b#

  经查看发现这个目录的属主不是root,所以启动ssh报错

  -bash-2.05b# ls -ld /var/empty/sshd/

  d–x–x–x 2 vu00106 root 1024 Feb 2 2005 /var/empty/sshd/

  -bash-2.05b#

  修改为root属主,启动成功

  -bash-2.05b# chown root /var/empty/sshd/

  -bash-2.05b# /etc/init.d/sshd start

  Starting sshd: [ OK ]

  -bash-2.05b#

  至此问题修复。

  另外,还可以尝试:

  这个是权限的问题

  可采取以下两步解决

  chown -R root.root /var/empty/sshd

  chmod 744 /var/empty/sshd

  service sshd restart

  就可以解决上述的问题。
