2024年8月30日（docker部署project-exam-system系统 并用Dockerfile构建java镜像）

一、回顾

1.使用harbao仓库

1. Python -- version

2. yum -y update

3. yum -y install python2-pip

4. pip install -- upgrade pip == 20.3 -i https://mirrors.aliyun.com/pypi/simple

5. pip install docker-compose -i https://mirrors.aliyun.com/pypi/simple

6. source docker.sh

7.解压harbar

8. vim harbor.yml

9. hostname

10. https注释

11. ./prepare

12. ./installed

13. 使用nginx发布web服务

14. 使用registry管理

2.docker-compose的编排

1. 在学习kubernetes之前的热身

2.通过运行一个yum管理docker容器

3. docker-compose.yml

vim docker-compose
version: "2"
service: 
    nginx:
        contanner_name: name0
        images: nginx:latest
        ports:
        - "80:80"
        volumns:
        - /opt/web/:/usr/share/nginx/html/

二、项目：使用基础的docker指令来创建镜像，实现项目的发布

root@docker \~\]# vim /etc/docker/daemon.json ```javascript { "registry-mirrors": [ "https://do.nark.eu.org", "https://dc.j8.work", "https://docker.m.daocloud.io", "https://dockerproxy.com", "https://docker.mirrors.ustc.edu.cn", "https://docker.nju.edu.cn" ] } ``` \[root@docker \~\]# systemctl start docker 拉取nginx \[root@docker \~\]# docker pull nginx

三、docker部署project-exam-system系统

1、背景：在一台主机之内实现容器的编排，发布考试系统

2、环境准备：

1. docker

vim /etc/docker/daemon.json

{
        "registry-mirrors": [
                "https://do.nark.eu.org",
                "https://dc.j8.work",
                "https://docker.m.daocloud.io",
                "https://dockerproxy.com",
                "https://docker.mirrors.ustc.edu.cn",
                "https://docker.nju.edu.cn"
        ]
}

2. docker-compose

3、普通的部署

1. 镜像

**前端：**nginx latest服务

拉取nginx：latest镜像

测试

上传前端项目dist

后端的业务： spring boot不能单独部署tomcat，已经在spring boot中内置tomcat

1. 准备拉取基础centos镜像

2. jdk17版本的文件

3. 项目资源.war .. perpreties

4. 将在服务器上的Java的资源文件上传到容器

5. 对已经上传到容器的文件进行部署 docker attach 57

6. tar -xzvf jdk-17_linux-x64_bin.tar.gz -C /usr/local/jdk/ --strip-components=1

7. 尝试启动

**数据持久化业务：**MySQL5.7.44

前端

（1）创建nginx容器

root@docker \~\]# docker run -itd -p80:80 nginx:latest ```javascript [root@docker ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 56c77a78a1c1 nginx:latest "/docker-entrypoint...." 40 seconds ago Up 39 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp admiring_banach ``` \[root@docker \~\]# docker exec -it 56 ls /usr/share/nginx/html 50x.html index.html

（2）创建一个目录，不单独放置前端的资料，把后端的资料也都放到这里

root@docker \~\]# mkdir project_exam_system \[root@docker \~\]# cd project_exam_system/ \[root@docker project_exam_system\]# mkdir web

（3）上传文件

C:\Users\89765>scp -r "D:\青岛实训\project_exam_system\dist" root@192.168.8.196:~/project_exam_system/web/

root@docker project_exam_system\]# ls web \[root@docker project_exam_system\]# ls web/ dist \[root@docker project_exam_system\]# ls web/dist/ assets favicon.ico index.html

（4）删除之前创建的nginx容器

root@docker project_exam_system\]# docker stop 56 56 \[root@docker project_exam_system\]# docker rm 56 56

（5）再创建容器，不止映射端口，还挂载目录

root@docker project_exam_system\]# docker run -itd -p80:80 -v /root/project_exam_system/web/dist/:/usr/share/nginx/html/ nginx:latest 881bf9bd662746918396fc79254e0fde7fd382ab6c14973304f6069bea644619 \[root@docker project_exam_system\]# docker exec -it 88 ls /usr/share/nginx/html assets favicon.ico index.html

（6）测试成功

出现问题,在实现登录的时候,都实现后段异常,原因后段还没后部署

登录的时候请求的域名bu.yuanyu.zhangmin,我们是hosts域名劫持来实现

vi /etc/hosts
192.168.8.196 bu.yuanyu.zhangmin

sudo echo "192.168.8.196 bu.yuanyu.zhangmin" >> /etc/hosts

后端

（1）上传包

（2）创建容器

root@docker \~\]# docker run -it centos:latest /bin/bash \[root@573bb9975f03 /\]# ls bin etc lib lost+found mnt proc run srv tmp var dev home lib64 media opt root sbin sys usr \[root@573bb9975f03 /\]# \[root@docker \~\]#

（3）将在服务器上的Java的资源文件上传到容器

root@docker \~\]# docker cp application.properties 57:/ Successfully copied 4.1kB to 57:/ \[root@docker \~\]# docker cp Project_ExamSystem-V1.0.0.war 57:/ Successfully copied 41MB to 57:/ \[root@docker \~\]# docker cp jdk-17_linux-x64_bin.tar.gz 57:/ Successfully copied 183MB to 57:/

（4）进入容器

root@docker \~\]# docker attach 57 ```Delphi [root@573bb9975f03 /]# ls Project_ExamSystem-V1.0.0.war lib64 sbin application.properties lost+found srv bin media sys dev mnt tmp etc opt usr home proc var jdk-17_linux-x64_bin.tar.gz root lib run ```

（5）创建jdk解压目录

root@573bb9975f03 /\]# mkdir /usr/local/jdk

（6）解压jdk包

root@573bb9975f03 /\]# tar -xzvf jdk-17_linux-x64_bin.tar.gz -C /usr/local/jdk/ --strip-components=1

（7）修改application.properties 文件

root@573bb9975f03 /\]# vi application.properties ```bash spring.datasource.url=jdbc:mysql://192.168.8.196:3306/project_exam_system #本机IP地址 spring.datasource.username=lxe spring.datasource.password=lxe spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver ```

（8）尝试启动

root@573bb9975f03 /\]# /usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war **CTRL+P+Q** \[root@docker \~\]# curl 172.17.0.3:8080 {"code":20002,"msg":"账号不存在或密码错误"}\[root@docker \~\]#

（9）根据容器57创建镜像

root@docker \~\]# docker commit 57 java:v0 \[root@docker \~\]# docker images ```bash REPOSITORY TAG IMAGE ID CREATED SIZE java v0 b27ef2926644 6 seconds ago 774MB ```

（10）删除掉上面的57容器

root@docker \~\]# docker stop 57 57 \[root@docker \~\]# docker rm 57 57

（11）根据新建的镜像创建镜像

root@docker \~\]# docker run -itd -p8080:8080 java:v0 /usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war \[root@docker \~\]# docker ps ```bash CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 7f42f4f5381a java:v0 "/usr/local/jdk/bin/..." 6 seconds ago Up 5 seconds 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp happy_hodgkin ``` \[root@docker \~\]# docker stop 7f 7f \[root@docker \~\]# docker rm 7f 7f

（12）重新创建容器

root@docker \~\]# docker run -itd -p8080:8080 java:v0 2cd9c025556983e6710ff6cd508a94d6df9217ba05f79c673bab1beadc35e5f2 \[root@docker \~\]# docker ps ```bash CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2cd9c0255569 java:v0 "/bin/bash" 12 seconds ago Up 12 seconds 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp beautiful_haslett 881bf9bd6627 nginx:latest "/docker-entrypoint...." About an hour ago Up About an hour 0.0.0.0:80->80/tcp, :::80->80/tcp goofy_agnesi ``` \[root@docker \~\]# docker attach 2c //将java容器的终端附加到当前终端 \[root@2cd9c0255569 /\]# /usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war //启动spring boot微服务

（1）拉取MySQL镜像

root@docker \~\]# docker pull mysql:5.7.44 \[root@docker \~\]# docker images ```bash mysql 5.7.44 5107333e08a8 8 months ago 501MB ```

（2）创建容器并映射端口

root@docker \~\]# docker run -itd -e MYSQL_ROOT_PASSWORD=root -p3306:3306 mysql:5.7.44 \[root@docker \~\]# docker ps ```bash CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 408f1e6cec5b mysql:5.7.44 "docker-entrypoint.s..." 4 seconds ago Up 4 seconds 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp pedantic_solomon ```

（3）向容器中上传文件

root@docker \~\]# docker cp 408:/var/lib/mysql project_exam_system/ ```bash Successfully copied 220MB to /root/project_exam_system/ ```

（4）将mysql文件上传

C:\Users\89765>scp "D:\青岛实训\project_exam_system\project_exam_system.sql" root@192.168.8.196:~/project_exam_system

root@docker \~\]# cd project_exam_system/ \[root@docker project_exam_system\]# ls mysql project_exam_system.sql web \[root@docker project_exam_system\]# rm -rf mysql/ \[root@docker project_exam_system\]# mkdir mysql \[root@docker project_exam_system\]# mv project_exam_system.sql mysql/ \[root@docker project_exam_system\]# head mysql/project_exam_system.sql ```bash create database if not exists project_exam_system charset utf8mb4; use project_exam_system; /* Navicat MySQL Data Transfer Source Server : MySQL84 Source Server Type : MySQL Source Server Version : 80400 Source Host : localhost:3308 Source Schema : project_exam_system ```

（5）将sql文件上传到mysql容器中

root@docker \~\]# docker cp project_exam_system/mysql/project_exam_system.sql 40:/ Successfully copied 11MB to 40:/ \[root@docker \~\]# docker exec 40 ls project_exam_system.sql 

（6）使用exec指令访问数据库管理界面

#由于在java的配置文件中,访问数据库的账号和密码不是root,而是lxe

root@docker \~\]# docker exec -it 40 mysql -uroot -proot ```sql mysql> show databases; +---------------------+ | Database | +---------------------+ | information_schema | | mysql | | performance_schema | | project_exam_system | | sys | +---------------------+ 5 rows in set (0.00 sec) mysql> create user 'lxe'@'%' identified by 'lxe'; Query OK, 0 rows affected (0.00 sec) mysql> grant all on *.* to 'lxe'@'%'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) ``` 

4、Dockerfile

创建java资源存放目录，并将所有资源文件移动到java目录中

root@docker \~\]# mkdir project_exam_system/java \[root@docker \~\]# mv jdk-17_linux-x64_bin.tar.gz project_exam_system/java/ \[root@docker \~\]# mv application.properties project_exam_system/java/ \[root@docker \~\]# mv Project_ExamSystem-V1.0.0.war project_exam_system/java/ \[root@docker \~\]# tree -L 3 project_exam_system/ ```Delphi project_exam_system/ ├── java │ ├── application.properties │ └── jdk-17_linux-x64_bin.tar.gz ├── mysql │ └── project_exam_system.sql └── web └── dist ├── assets ├── favicon.ico └── index.html 5 directories, 5 files ``` **编写Dockerfile文件** \[root@docker \~\]# vim project_exam_system/java/Dockerfile ```Delphi FROM centos:latest ADD application.properties /application.properties ADD jdk/ /usr/local/jdk ADD Project_ExamSystem-V1.0.0.war /Project_ExamSystem-V1.0.0.war ADD java.sh /java.sh RUN chmod -v +x /java.sh WORKDIR / EXPOSE 8080 CMD [ "java.sh","/bin/bash" ] ``` **进入到java资源目录中并解压jdk，并改名** \[root@docker \~\]# cd project_exam_system/java/ \[root@docker java\]# tar -xzvf jdk-17_linux-x64_bin.tar.gz \[root@docker java\]# mv jdk-17.0.12/ jdk **使用当前目录下的Dockerfile来构建一个名为java:v1的镜像。** \[root@docker java\]# docker build -t java:v1 . ```Delphi [root@docker java]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE java v1 541d15b51e02 58 seconds ago 591MB ``` \[root@docker java\]# vim java.sh ```Delphi #!/bib/bash /usr/local/jdk/bin/java -jar Project_ExamSystem-v1.0.0.war ``` **根据java:v1镜像创建容器** \[root@docker java\]# docker run -it -p8081:8080 java:v1 /bin/bash \[root@1ef5404323e8 /\]# ls ```Delphi Project_ExamSystem-V1.0.0.war home media run usr application.properties java.sh mnt sbin var bin lib opt srv dev lib64 proc sys etc lost+found root tmp ``` \[root@1ef5404323e8 /\]# /usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war \[root@docker java\]# docker exec 1ef ss -anut\| grep 8080 ```Delphi tcp LISTEN 0 128 *:8080 *:* ```
