[root@b5926410fe60 /]# yum install passwd openssl openssh-server -y
 
启动sshd:
# /usr/sbin/sshd -D
这时报以下错误:
[root@ b5926410fe60 /]# /usr/sbin/sshd
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Could not load host key: /etc/ssh/ssh_host_ed25519_key
 
 
执行以下命令解决:
[root@b5926410fe60 /]# ssh-keygen -q -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key -N ''  
[root@b5926410fe60 /]# ssh-keygen -q -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ''
[root@b5926410fe60 /]# ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key -N '' 
 
然后,修改 /etc/ssh/sshd_config 配置信息:
UsePAM yes 改为 UsePAM no 
UsePrivilegeSeparation sandbox 改为 UsePrivilegeSeparation no
 
[root@b5926410fe60 /]# sed -i "s/#UsePrivilegeSeparation.*/UsePrivilegeSeparation no/g" /etc/ssh/sshd_config
[root@b5926410fe60 /]# sed -i "s/UsePAM.*/UsePAM no/g" /etc/ssh/sshd_config
 
修改完后,重新启动sshd
[root@b5926410fe60 /]# /usr/sbin/sshd -D

 

 

制作:

yum install -y passwd openssl openssh-server ssh-keygen -q -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key -N ''  
ssh-keygen -q -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ''
ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key -N '' 
 
然后,修改 /etc/ssh/sshd_config 配置信息:
UsePAM yes 改为 UsePAM no 
UsePrivilegeSeparation sandbox 改为 UsePrivilegeSeparation no
 
sed -i "s/#UsePrivilegeSeparation.*/UsePrivilegeSeparation no/g" /etc/ssh/sshd_config
sed -i "s/UsePAM.*/UsePAM no/g" /etc/ssh/sshd_config

更改root密码
passwd root
/usr/sbin/sshd -D

 

Dockerfile:
