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。
. e: j$ c" r0 u& o7 Y
3 g4 B# a( @* f8 O9 n./configure --prefix=/usr/local/openssh --with-ssl-dir=/usr/local/openssl/
1 u: B% w0 j9 ~2 D% L# _保持这样即可。
( n1 Q/ u4 E( d; U不再执行rpm -e openssh-server这个操作

' E7 N) l! j: j( N3 K5 j
后面操作这样即可；
#copy file
\cp -fp  /etc/ssh-bak/sshd_config /usr/local/openssh/etc/sshd_config
