openssh升级
rpm -e `rpm -qa|grep openssh` --nodeps (卸载openssh)
tar -zxvf openssh-7.7p1.tar.gz
cd openssh-7.7p1
./configure --prefix=/usr/local/openssh --with-ssl-dir=/usr/local/ssl --with-zlib=/usr/local/zlib

vi /etc/ssh/sshd_config(查看sftp后跟的路径是否正确)
Subsystem sftp /usr/local/openssh/libexec/sftp-server
6#######################默认root不能远程ssh登录,需要su,以下配置root远程可以登录
vi /etc/ssh/sshd_config
PasswordAuthentication yes
PermitRootLogin yes
vi /etc/init.d/sshd
在$SSHD $OPTIONS && success || failure上方一行添加如下
OPTIONS="-f /etc/ssh/sshd_config"
