一、构建SSHD镜像

创建目录，编写Dockerfile文件

[root@docker opt]# mkdir sshd
[root@docker opt]# cd sshd/
[root@docker sshd]# vim Dockerfile
FROM centos:7
MAINTAINER The Centos Project <sshd-centos>
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
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
RUN sed -i '/^session\s\+required\s\+pam_loginuid.so/s/^/#/' /etc/pam.d/sshd
RUN mkdir -p /root/.ssh && chown root.root /root && chmod 700 /root/.ssh
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]

生成镜像

[root@docker sshd]# docker build -t sshd:new .

启动容器，随机端口号

[root@docker sshd]# docker run -d -P sshd:new
[root@docker sshd]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS                    NAMES
7c684db2b2ab        sshd:new            "/usr/sbin/sshd -D"      16 seconds ago      Up 15 seconds               0.0.0.0:32769->22/tcp    eager_taussig

登录测试

[root@docker sshd]# ssh localhost -p 32769
[root@7c684db2b2ab ~]# ls
anaconda-ks.cfg

二、构建systemctl镜像

创建目录，编写Dockerfile文件

[root@docker opt]# mkdir systemctl
[root@docker opt]# cd systemctl/
[root@docker systemctl]# vim Dockerfile
FROM sshd:new
ENV container docker
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

[root@docker systemctl]# docker build -t systemd:new 

创建容器

[root@docker systemctl]# docker run --privileged -ti -v /sys/fs/cgroup:/sys/fs/
cgroup:ro systemd:new /sbin/init &
[1] 22513
[root@docker systemctl]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS                    NAMES
ca53a9fe6ae8        systemd:new         "/sbin/init"             10 seconds ago      Up 8 seconds                22/tcp                   mystifying_meitner

进入容器进行测试

[root@docker systemctl]# docker exec -it ca53a9fe6ae8 /bin/bash
[root@ca53a9fe6ae8 /]# systemctl status sshd
● sshd.service - OpenSSH server daemonLoaded: loaded (/usr/lib/systemd/system/sshd.service; disabled; vendor preset: enabled)Active: inactive (dead)Docs: man:sshd(8)man:sshd_config(5)

[root@ca53a9fe6ae8 /]# systemctl status sshd
● sshd.service - OpenSSH server daemonLoaded: loaded (/usr/lib/systemd/system/sshd.service; disabled; vendor preset: enabled)Active: active (running) since Mon 2020-09-21 07:52:43 UTC; 2s agoDocs: man:sshd(8)man:sshd_config(5)Main PID: 50 (sshd)CGroup: /docker/ca53a9fe6ae82cb7730fc441a25c7fa84a8db1bc788b9a9701f240f61b97028f/system.slice/sshd.service└─50 /usr/sbin/sshd -D

三、构建Nginx镜像

创建目录并编写Dockerfile文件

[root@docker opt]# mkdir nginx
[root@docker opt]# cd nginx/
[root@docker nginx]# vim Dockerfile
FROM centos:7
MAINTAINER this is nginx-centos
RUN yum -y update
RUN yum -y install gcc gcc-c++ make pcre-devel zlib-devel
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.2.tar.gz /usr/local/src
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
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf
ADD run.sh /run.sh
RUN chmod 755 /run.sh
CMD ["/run.sh"]
[root@docker nginx]# vim run.sh
#!/bin/bash
/usr/local/nginx/sbin/nginx

生成镜像

[root@docker nginx]# docker build -t nginx:new .

创建容器，随机端口

[root@docker nginx]# docker run -d -P nginx:new 
650fb295f87796e090f4fdf6b8a97c6e19b256fdee07684674eef79146b4fd8f
[root@docker nginx]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                        PORTS                                           NAMES
650fb295f877        nginx:new           "/run.sh"           4 seconds ago       Up 3 seconds                  0.0.0.0:32771->80/tcp, 0.0.0.0:32770->443/tcp   thirsty_keldysh

测试访问

四、构建Tomcat镜像

创建目录并编写Dockerfile文件，上传相关文件

[root@docker tomcat]# ls
apache-tomcat-9.0.16.tar.gz  Dockerfile  jdk-8u91-linux-x64.tar.gz
[root@docker tomcat]# vim Dockerfile
FROM centos:7
MAINTAINER this is tomcat-centos
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 JAVA_BIN /usr/local/java/bin
ENV JRE_HOME /usr/local/java/jre
ENV PATH $PATH:/usr/local/java/bin:/usr/local/java/jre/bin
ENV CLASSPATH /usr/lcoal/java/jre/bin:/usr/local/java/lib:/usr/local/java/jre/lib/charsets.jar
ADD apache-tomcat-9.0.16.tar.gz /usr/local
WORKDIR /usr/local
RUN mv apache-tomcat-9.0.16 tomcat9
EXPOSE 8080
ENTRYPOINT ["/usr/local/tomcat9/bin/catalina.sh","run"]

生成镜像

[root@docker tomcat]# docker build -t tomcat:new .

创建容器，指定端口号

[root@docker tomcat]# docker run -d --name tomcat01 -p 1111:8080 tomcat:new 
97adc43c451fd8c8a9f50a6909efdeb25e8edc76d39d9ac6c0031a9183e9aa4d

五、构建MySQL镜像

[root@docker mysql]# ls
mysql-boost-5.7.20.tar.gz

创建目录并编写Dockerfile文件

[root@docker mysql]# vim Dockerfile 
FROM centos:7
MAINTAINER this is mysql-centos
RUN  yum -y install ncurses bison cmake gcc ncurses-devel gcc-c++ make
RUN useradd mysql -M -s /sbin/nologin
ADD mysql-boost-5.7.20.tar.gz /usr/local/src
WORKDIR /usr/local/src/mysql-5.7.20
RUN cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1
RUN make && make install
RUN chown -R mysql:mysql /usr/local/mysql/
RUN rm -rf /etc/my.cnf
ADD my.cnf /etc/
RUN chown mysql.mysql /etc/my.cnf
ENV PATH /usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
RUN /usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /lib/systemd/system/
EXPOSE 3306
ADD run.sh /run.sh
RUN chmod 755 /run.sh
CMD ["/run.sh"]

编写配置文件

[root@docker mysql]# vim my.cnf 
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock[mysql]
port = 3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

启动脚本

[root@docker mysql]# vim run.sh 
#!/bin/bash
/usr/local/mysql/bin/mysqld
systemctl enable mysqld

生成镜像

[root@docker mysql]# docker run -d -P --privileged mysqld:new
6860174a05539e34521ef0e30d2dd3ac557f6f5fe550fa27f02ecb731489003c
[root@docker mysql]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                      PORTS                     NAMES
6860174a0553        mysqld:new          "/run.sh"           8 seconds ago       Up 8 seconds                0.0.0.0:32768->3306/tcp   cranky_herschel

进入镜像中mysql数据库，进行验证

[root@docker mysql]# docker exec -it 6860174a0553 /bin/bash
[root@6860174a0553 mysql-5.7.20]# mysql -uroot -p

其它节点安装mariadb进行测试

[root@docker ~]# yum install mariadb* -y
[root@docker ~]# systemctl start mariadb.service 

连接数据库

[root@docker ~]# mysql -h 192.168.179.129 -uroot -P 32768 -p
