docker 容器内启动 sshd 启动报错

创建容器设置密码 安装 openssh-server 启动出错

在容器内 使用 /usr/sbin/sshd -d 启动报错？

[root@9d41c7f36c5e tmp]# /usr/sbin/sshd -d
debug1: sshd version OpenSSH_7.4, OpenSSL 1.0.2k-fips  26 Jan 2017
debug1: key_load_private: No such file or directory
debug1: key_load_public: No such file or directory
Could not load host key: /etc/ssh/ssh_host_rsa_key
debug1: key_load_private: No such file or directory
debug1: key_load_public: No such file or directory

debug1: key_load_public: No such file or directory
Could not load host key: /etc/ssh/ssh_host_ed25519_key
sshd: no hostkeys available -- exiting.

解决办法：

# /usr/sbin/sshd-keygen -A
# ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
# ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

再重新执行启动
# /usr/sbin/sshd
