docker镜像创建 2 ——实战（SSHD、LNMP）

docker镜像实战Docker云计算

实验1 构建ssh镜像容器

#创建sshd的工作目录
mkdir /opt/sshd
cd /opt/sshd
vim Dockerfile

.............................................
#第一行必须指明基于的基础镜像
FROM centos:7

#作者信息.
MAINTAINER this is ssh image <lp>

#镜像的操作指令
RUN yum -y update
RUN yum -y install openssh* net-tools lsof telnet passwd
RUN echo ' 123456' | passwd --stdin root 
RUN sed -i ' s/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config         #不使用PAM认证
RUN sed -ri ' /^session\s+required\s+pam loginuid.so/ s/^/#/' /etc/pam.d/sshd     #取消pam限制

RUN ssh- keygen -t rsa -A            #生成密钥认证文件
RUN mkdir -p /root/.ssh && chown root.root /root && chmod 700 /root/.ssh              
EXPOSE 22
CMD ["/usr/sbin/sshd" ，"-D"]             #/usr/sbin/sshd -D用于前台启动sshd服务
..............................................................

//生成镜像,千万注意"."不要忘记了！不是多打的字符
#记得在工作目录下生成镜像哦！
docker build -t sshd:centos .

//启动容器并修改root密码

docker run -d -P sshd: centos

docker ps -a

ssh localhost -p 
(然后输入密码123456；我dockerfile里面设置得就行）
#第一次有警告，记得yes

创建sshd的工作目录
1.png
编写dockerfile文件
1.1.png
然后在/opt/sshd目录当中创建镜像
1.2.png
显示创建镜像成功
1.21.png
运行这个镜像用ps -a 检查是否启动
2.png
使用ssh localhost -p 登录sshd容器
3.png

构建完成sshd的容器后，下面再容器中构建sshd的Systemctl镜像来查看信息状态

#创建systemctl
mkdir /opt/systemctl
cd /opt/systemctl
vim Dockerfile

.....................................
FROM sshd:centos
MAINTAINER this is systemctl image <zjh>
ENV container docker

#除了systemd-tmpfiles-setup.service，删除其它所有文件
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i;done); \

rm -f /lib/systemd/system/multi-user.target.wants/*; \ 
rm -f /etc/systemd/system/*.wants/*; \
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]

#CMD ["/usr/sbin/init"]

//生成镜像

docker build -t systemd:centos .

//启动容器，并挂载宿主机目录挂载到容器中，和进行初始化

docker run --privileged -d -P -v /sys/fs/cgroup:/sys/fs/cgroup:ro systemd:centos /sbin/init

#--privileged: 使container内的root拥有真正的root权限。 否则，container内的root只是外部的一 个普通用户权限。
docker ps -a

//进入容器

docker exec -it f4a367e951b8 bash

systemctl status sshd

创建工作目录，根据上面的sshd:centos继续堆
1.png
1.1.png

完成后出来在/opt/systemctl目录中构建镜像
2.png
2.1.png

启动镜像，查看ps -a 是否正常运行
2.2.png
进入到这个镜像当中，使用systemcrl命令来查看sshd的状态，或者使用systemctl命令来操作sshd的状态

实验 构建docker容器-LNMP（实战项目）

环境：（docker ip）
192.168.100.1 nginx doc01
192.168.100.2 mysql doc02
192.168.100.3 php doc03
默认所有机器关闭防火墙、配好yum

```html/xml
首先部署nginx
#部署自定义网络，部署nginx（容器IP 为 192.168.100.1
#容器ip是容器ip，ens33实体网卡ip是另外一个ip，别搞混了！！！
docker network create --subnet=192.168.100.0/24 --opt "com.docker.network.bridge.name"="docker1" mynetwork

#创建工作目录
mkdir /opt/nginx
cd /opt/nginx/

#上传 nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz、nginx.conf配置文件 到 /opt/nginx/ 目录中

mkdir /opt/nginx/html #创建相应文件给nginx解压
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

vim Dockerfile
.........................................................
FROM centos:7
MAINTAINER this is nginx image <zjh>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.0.tar.gz /usr/local/src/
WORKDIR /usr/local/src/nginx-1.12.0
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
ENV PATH /usr/local/nginx/sbin:$PATH
ADD nginx.conf /usr/local/nginx/conf/
#ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html/
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
EXPOSE 443
ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]
.............................................................
#创建nginx镜像
docker build -t nginx:lnmp .

#运行容器
docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 192.168.100.1 nginx:lnmp

首先是创建自定义网络，然后创建nginx的工作目录，然后切换进去吧nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz、nginx.conf配置文件传进去（nginx.conf自己先配好）

随后我们创建相应文件给nginx解压，解压文件即可
![2.png](https://s2.51cto.com/images/20220309/1646833506975415.png?x-oss-process=image/watermark,size_14,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=)
下面是在 /opt/nginx/里创建dockerfile文件

![3.1.png](https://s2.51cto.com/images/20220309/1646833556144569.png?x-oss-process=image/watermark,size_14,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=)
成功创建镜像文件
![3.png](https://s2.51cto.com/images/20220309/1646833587310035.png?x-oss-process=image/watermark,size_14,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=)
![3.2.png](https://s2.51cto.com/images/20220309/1646833591834327.png?x-oss-process=image/watermark,size_14,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=)
运行镜像，然后就把他运行起来就行

```html/xml
下面我们创建mysql-docker02
192.168.100.2

#部署mysql（容器IP 为 192.168.100.2）
mkdir /opt/mysqld
