6.docker手动制作镜像(基于C6)

1.制作一个基于centOS6版的Nginx镜像(单服务)

11.启动并进入容器

[root@docker03 ]# docker run -it -p 80:80 centos:6.9 /bin/bash [root@9dac33fe6bda /]#

[root@9dac33fe6bda /]# nginx

1.5测试

1.6提交镜像

[root@docker03 ~]# docker commit 9dac33fe6bda sha256:b3b5ec6779bd43731aa3e1639811d1583a4404cb2296dab75a4f8c7e41d62b6a [root@docker03 ~]# docker commit 9dac33fe6bda docker_centos6.9_nginx:v1 sha256:f954a629873f40f5b70676cc2618c4766b9ef161e4e46c38b89327b613662f4f [root@docker03 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker_centos6.9_nginx v1 f954a629873f 7 seconds ago 446MB

1.7测试镜像功能

[root@docker03 /opt]# docker run -d -p 80:80 -v /opt:/usr/share/nginx/html docker_centos6.9_nginx:v1 nginx -g 'daemon off; ' 085ea855e734a0aa4aacb739b6de788f03e9d288bf16719fd1ad2e94de5896d0

2.制作一个基于centOS版的可道云镜像(多服务)

2.1启动并进入容器

[root@docker03 /opt]# docker run -it -p 80:80 centos:6.9 /bin/bash [root@274ca61dd89f /]#

2.2更改容器系统的yum源和epel源

[root@274ca61dd89f /]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 110 664 110 664 0 0 4205 0 --:--:-- --:--:-- --:--:-- 7545 [root@274ca61dd89f /]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 2523 100 2523 0 0 25788 0 --:--:-- --:--:-- --:--:-- 61536

2.3安装nginx

2.4安装PHP服务

[root@274ca61dd89f /]# yum install php-fpm php-gd php-mbstring -y

2.5更改PHP配置文件用户和用户组

[root@274ca61dd89f /]# vi /etc/php-fpm.d/conf

2.6启动PHP服务

[root@274ca61dd89f /]# service php-fpm start Starting php-fpm: [ OK ]

2.7更改nginx的配置文件

添加到vi /etc/nginx/conf.d/default.conf # # The default server # server { listen 80 default_server; listen [::]:80 default_server; server_name _; root /html; index index.php index.html index.htm; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { } location ~ \.php$ { root /html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /html$fastcgi_script_name; include fastcgi_params; }

2.11测试

2.12编写启动脚本（夯住起动命令在最后一个启动）

vi init.sh #!/bin/bash service php-fpm start nginx -g 'daemon off;' ~

2.13生成镜像

[root@docker03 /etc/nginx]# docker commit 274ca61dd89f docker_kod:v1 sha256:da72ea94c8cbf9f2c21b7655b4146b0308053c3988fc2b6d165a1f6dd4cbc8de

2.14测试镜像

[root@docker03 ~]# docker run -d -p 81:80 docker_kod:v1 /bin/bash /init.sh cd5d18b69f1438426da1283160c73cbe45c2d8f73e74f5adeec0211bf14b52b7

3.1.创建并进入容器

[root@docker03 ~]# docker run -it -p 83:80 centos:7 [root@c919e69954a2 /]#

3.2.更改容器系统的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 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo 100 2523 100 2523 0 0 17831 0 --:--:-- --:--:-- --:--:-- 17893 [root@c919e69954a2 /]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 664 100 664 0 0 5044 0 --:--:-- --:--:-- --:--:-- 5068

3.3.安装nginx

[root@c919e69954a2 /]# yum install nginx -y

3.4.启动服务

注：C7在容器中无法使用systemctl启动服务，因为bus进程没有启动，C7启动快是因为多个进程同时启动。

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

用手动启动服务

[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 [Unit] Description=The nginx HTTP and reverse proxy server After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/run/nginx.pid # 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. # https://bugzilla.redhat.com/show_bug.cgi?id=1268621 ExecStartPre=/usr/bin/rm -f /run/nginx.pid ExecStartPre=/usr/sbin/nginx -t ExecStart=/usr/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID KillSignal=SIGQUIT TimeoutStopSec=5 KillMode=process PrivateTmp=true [Install] WantedBy=multi-user.target /usr/sbin/nginx

3.5.安装ssh服务

[root@c919e69954a2 /]# yum install openssh-server -y

3.6启动sshd-keygen服务（因为没有密钥对，报错）

[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 ECDSA host key: /usr/sbin/sshd-keygen: line 105: success: command not found Generating SSH2 ED25519 host key: /usr/sbin/sshd-keygen: line 126: success: command not found

3.7在宿主机查询文件对应的软件包

[root@docker01 ~]# rpm -qf /etc/rc.d/init.d/functions initscripts-9.49.46-1.el7.x86_64

3.8安装软件包

[root@c919e69954a2 /]# yum install initscripts -y

3.9在启动sshd-keygen服务,查看秘钥对

[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启动sshd服务

[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 Wants=sshd-keygen.service [Service] Type=notify EnvironmentFile=/etc/sysconfig/sshd ExecStart=/usr/sbin/sshd -D $OPTIONS ExecReload=/bin/kill -HUP $MAINPID KillMode=process Restart=on-failure RestartSec=42s [Install] WantedBy=multi-user.target [root@c919e69954a2 /]# /usr/sbin/sshd -D

3.11设置容器登录密码

echo '123456' | passwd --stdin root

3.12连接测试
