再看secure日志：

最后能解决办法的是，通过重新安装openssh-server安装包。再次编译的时候，不添加--sysconfig=/etc/ssh   这个参数即可。

./configure --prefix=/usr/local/openssh --with-ssl-dir=/usr/local/openssl/
& b; [4 s0 b: q$ U保持这样即可。
不再执行rpm -e openssh-server这个操作


6 i8 r" E1 h) g, b& Z后面操作这样即可；
#copy file
\cp -fp  /etc/ssh-bak/sshd_config /usr/local/openssh/etc/sshd_config
ln -sf /usr/local/openssh/etc/sshd_config /etc/ssh/sshd_config
