给docker容器安装ssh

  1. [root@b5926410fe60 /]# yum install passwd openssl openssh-server -y

  2. 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 ”

  3. 修改 /etc/ssh/sshd_config 配置信息:

    UsePAM yes 改为 UsePAM no
    UsePrivilegeSeparation sandbox 改为 UsePrivilegeSeparation no

  4. [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

  5. 修改完后,重新启动sshd
    [root@b5926410fe60 /]# /usr/sbin/sshd -D

  6. 修改root密码
    [root@b5926410fe60 /]# passwd root
