cd5d18b69f1438426da1283160c73cbe45c2d8f73e74f5adeec0211bf14b52b7
3.docker手動制作鏡像(基于C7)(Nginx+ssh)
3.1.創建并進入容器
[root@docker03 ~]# docker run -it -p 83:80 centos:7
[root@c919e69954a2 /]#
3.2.更改容器系統的yum源和epel源
[root@c919e69954a2 /]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

Dload Upload Total Spent Left Speed
100 664 100 664 0 0 5044 0 --:--:-- --:--:-- --:--:-- 5068
3.3.安裝nginx
[root@c919e69954a2 /]# yum install nginx -y
3.4.啟動服務
注:C7在容器中無法使用systemctl啟動服務,因為bus進程沒有啟動,C7啟動快是因為多個進程同時啟動。
root@docker03 ~]# ps -ef |grep bus
dbus 6819 1 0 Dec12 ? 00:00:03 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
root 43281 40267 0 11:09 pts/1 00:00:00 grep --color=auto bus
[root@c919e69954a2 /]# systemctl start nginx
Failed to get D-Bus connection: Operation not permitted
用手動啟動服務
[root@c919e69954a2 /]# systemctl start nginx
Failed to get D-Bus connection: Operation not permitted
[root@c919e69954a2 /]# systemctl cat nginx
# /usr/lib/systemd/system/nginx.service

# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running `nginx -t` from the cmdline.

/usr/sbin/nginx
3.5.安裝ssh服務
[root@c919e69954a2 /]# yum install openssh-server -y
3.6啟動sshd-keygen服務(因為沒有密鑰對,報錯)
[root@c919e69954a2 /]# /usr/sbin/sshd-keygen
/usr/sbin/sshd-keygen: line 10: /etc/rc.d/init.d/functions: No such file or directory
Generating SSH2 RSA host key: /usr/sbin/sshd-keygen: line 63: success: command not found

Generating SSH2 ED25519 host key: /usr/sbin/sshd-keygen: line 126: success: command not found
3.7在宿主機查詢文件對應的軟件包
[root@docker01 ~]# rpm -qf /etc/rc.d/init.d/functions
initscripts-9.49.46-1.el7.x86_64
3.8安裝軟件包
[root@c919e69954a2 /]# yum install initscripts -y
3.9在啟動sshd-keygen服務,查看秘鑰對
[root@c1e50af6f42c /]# /usr/sbin/sshd-keygen
Generating SSH2 RSA host key: [ OK ]
Generating SSH2 ECDSA host key: [ OK ]
Generating SSH2 ED25519 host key: [ OK ]
[root@c919e69954a2 /]# ls /etc/ssh/
moduli ssh_host_ecdsa_key.pub ssh_host_ed25519_key.pub ssh_host_rsa_key.pub
ssh_host_ecdsa_key ssh_host_ed25519_key ssh_host_rsa_key sshd_config
3.10啟動sshd服務
[root@c919e69954a2 /]# systemctl cat sshd
# /usr/lib/systemd/system/sshd.service
[Unit]
Description=OpenSSH server daemon
Documentation=man:sshd(8) man:sshd_config(5)
After=network.target sshd-keygen.service

EnvironmentFile=/etc/sysconfig/sshd
ExecStart=/usr/sbin/sshd -D $OPTIONS
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure

[Install]
WantedBy=multi-user.target
[root@c919e69954a2 /]# /usr/sbin/sshd -D
3.11設置容器登錄密碼
echo '123456' | passwd --stdin root
3.12連接測試
