docker
一、构建SSH镜像
1.1 创建目录
- mkdir /opt/sshd
- cd /opt/sshd
1.2 制作脚本
- 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 <cccc>
#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
#/usr/sbin/sshd -D 用于前台启动sshd
CMD ["/usr/sbin/sshd" , "-D"]
1.3 生成镜像
docker build -t sshd:centos .
# . 表示所有文件
1.4 启动容器并修改root密码
docker run -d -P sshd:centos
docker ps -a
ssh localhost -p 49155
二、构建 systemctl 镜像
2.1 创建目录
- mkdir /opt/systemctl
- cd /opt/systemctl
2.2 制作脚本
- vim Dockerfile
FROM sshd:centos
MAINTAINER this is systemctl image <wl>
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 $i; done); \\
rm -f /lib/systemd/system/multi-user.target.wants/*; \\
rm -f /etc/systemd/system/*.wants/*; \\
rm -f /lib/systemd/system/local-fs.target.wants/*; \\
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \\
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \\
rm -f /lib/systemd/system/basic.target.wants/*;\\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
#CMD ["/usr/sbin/init"]
2.3 生成镜像
docker build -t systemd:centos .
2.4 启动
启动容器，并挂载宿主机目录挂载到容器中，和进行初始化
docker run --privileged -it -v /sys/fs/cgroup:/sys/fs/cgroup:ro systemd:centos /sbin/init &
#--privileged：使container内的root拥有真正的root权限。否则，container内的root只是外部的一个普通用户权限。
- docker ps -a
2.5 进入容器
方法一
docker exec -it c7d1f01ba29c bash
systemctl status sshd
方法二
docker run -d -P --privileged sshd:centos /usr/sbin/init &
三、构建nginx镜像
3.1 创建目录
- mkdir /opt/nginx
- cd /opt/nginx/
3.2 制作脚本
- vim Dockerfile
#基于基础镜像
FROM centos:7
#用户信息
MAINTAINER this is nginx image <cccc>
#添加环境包
RUN yum -y update
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
#上传nginx软件压缩包，并解压
ADD nginx-1.12.2.tar.gz /usr/local/src/
#指定工作目录
WORKDIR /usr/local/src/nginx-1.12.2
RUN ./configure \\
--prefix=/usr/local/nginx \\
--user=nginx \\
--group=nginx \\
--with-http_stub_status_module && make && make install
ENV PATH /usr/local/nginx/sbin:$PATH
#指定http和https端口
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf #关闭 nginx 在后台运行
#添加宿主机中run.sh到容器中
ADD run.sh /run.sh
RUN chmod 755 /run.sh
CMD ["/run.sh"]
- vim run.sh
#!/bin/bash
/usr/local/nginx/sbin/nginx
3.3 创建新镜像
docker build -t nginx:centos .
docker run -d -P nginx:centos
- docker ps -a
3.4 访问
http://192.168.253.11:49157
四、构建tomcat镜像
4.1 创建目录
- mkdir /opt/tomcat
- cd /opt/tomcat
4.2 制作脚本
- vim Dockerfile
FROM centos:7
MAINTAINER this is tomcat image <cccc>
ADD jdk-8u91-linux-x64.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv jdk1.8.0_91 /usr/local/java
ENV JAVA_HOME /usr/local/java
ENV JRE_HOME $JAVA_HOME/jre
ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib
ENV PATH $JAVA_HOME/bin:$PATH
ADD apache-tomcat-8.5.16.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv apache-tomcat-8.5.16 /usr/local/tomcat
EXPOSE 8080
#CMD ["/usr/local/tomcat/bin/catalina.sh","run"]
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]
4.3 创建新镜像
docker build -t tomcat:centos .
docker run -d --name tomcat01 -p 1216:8080 tomcat:centos
4.4 测试
http://192.168.253.11:1216
五、构建mysql镜像
5.1 创建目录
- mkdir /opt/mysqld
- cd /opt/mysqld
5.2 制作脚本
- vim Dockerfile
FROM centos:7
MAINTAINER this is mysql image <cccc>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
RUN useradd -M -s /sbin/nologin mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/

RUN sh /usr/local/src/run.sh
#CMD ["/usr/sbin/init"]
- vim my.cnf
[client]
port = 3306

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306

systemctl enable mysqld
5.3 创建新镜像
docker build -t mysql:centos .
5.4 启动容器，并进行初始化
