使用ssh连接docker

需求是使用 ssh 连接群晖套件 docker 中创建的 centos8 镜像，遇到的一些问题备忘，正常流程按第一篇参考文章顺序来。

查看22端口是否开启

ss -lnt

[root@centos8 /]# ss -lnt State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 *:22 *:*

安装 vim 和 ssh

yum install vim openssh-server openssh-clients -y

创建 sshd 脚本

vim /etc/init.d/sshd

#!/bin/sh # Start/stop/restart the secure shell server: sshd_start() { # Create host keys if needed. if [ ! -r /etc/ssh/ssh_host_key ]; then /usr/bin/ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_key -N '' fi if [ ! -f /etc/ssh/ssh_host_dsa_key ]; then /usr/bin/ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N '' fi if [ ! -f /etc/ssh/ssh_host_rsa_key ]; then /usr/bin/ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N '' fi /usr/sbin/sshd } sshd_stop() { killall sshd } sshd_restart() { if [ -r /var/run/sshd.pid ]; then echo "WARNING: killing listener process only. To kill every sshd process, you must" echo " use 'rc.sshd stop'. 'rc.sshd restart' kills only the parent sshd to" echo " allow an admin logged in through sshd to use 'rc.sshd restart' without" echo " being cut off. If sshd has been upgraded, new connections will now" echo " use the new version, which should be a safe enough approach." kill `cat /var/run/sshd.pid` else killall sshd fi sleep 1 sshd_start } case "$1" in 'start') sshd_start ;; 'stop') sshd_stop ;; 'restart') sshd_restart ;; *) echo "usage $0 start|stop|restart" esac

添加执行权限

chmod +x /etc/init.d/sshd

启动ssh服务

/etc/init.d/sshd start

安装 passwd

passwd: command not found

yum install passwd

[root@centos8 /]# passwd Changing password for user root. New password:

完成!
