部署project_exam_system项目——及容器的编排
（一）安装docker、编辑daemon.json文件、安装docker-compose编排容器、启动docker
1.环境准备
[root@docker--1 ~]# rz -E
rz waiting to receive.
[root@docker--1 ~]# ls
anaconda-ks.cfg docker.sh
[root@docker--1 ~]# source docker.sh
[root@docker--1 ~]# vim /etc/docker/daemon.json
[root@docker--1 ~]# vim /usr/lib/systemd/system/docker.service
[root@docker--1 ~]# systemctl daemon-reload
[root@docker--1 ~]# systemctl start docker
脚本内容如下：
cat << EOF | tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF
modprobe overlay
modprobe br_netfilter
cat << EOF | tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward = 1
EOF
sysctl --system
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y
2.普通部署
按照正常步骤安装docker，这里可参考前面的笔记
3.拉取nginx镜像
[root@docker3 ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
Digest: sha256:447a8665cc1dab95b1ca778e162215839ccbb9189104c79d7ec3a81e14577add
Status: Image is up to date for nginx:latest
docker.io/library/nginx:latest
4.查看镜像
[root@docker3 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest 5ef79149e0ec 2 weeks ago 188MB
5.创建nginx容器
[root@docker--1 ~]# docker run -itd -p80:80 nginx:latest a9200f608c60aa1c8827b5562b7906d543d48e38c06f76bdb1b702ce73209117
6.查看容器
[root@docker--1 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS NAMES
a9200f608c60 nginx:latest "/docker-entrypoint.…" 19 seconds ago Up 17 seconds cp stupefied_feistel
进行验证
[root@docker--1 ~]# curl localhost
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif; }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>
<p>For online documentation and support please refer to
nginx.org.<br/>
Commercial support is available at
nginx.com.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>
注：容器启动后nginx服务就自动发布了，浏览器也能够看到nginx页面
（二）部署project_exam_system项目
创建一个目录，放置前端和后端的资料
[root@docker--1 ~]# mkdir project_exam_system
切入到所创建的目录中
[root@docker--1 ~]# cd project_exam_system/
创建web目录
[root@docker--1 project_exam_system]# mkdir web
切入到web目录下
[root@docker--1 project_exam_system]# cd web/
拖拽dist.zip的压缩包
[root@docker--1 web]# rz -E
rz waiting to receive.
[root@docker--1 web]# ls
dist.zip
安装unzip
[root@docker--1 web]# yum -y install unzip
使用unzip进行解压dist.zip的包
[root@docker--1 web]# unzip dist.zip
[root@docker--1 web]# ls
dist dist.zip
[root@docker--1 web]# cd ..
停止并删除前面所创建的容器
停止容器
[root@docker--1 project_exam_system]# docker stop a92
a92
删除容器
[root@docker--1 project_exam_system]# docker rm a92
a92
创建容器，进行映射端口和挂载目录
[root@docker--1 project_exam_system]# docker run -itd -p80:80 -v /root/project_exam_syml/ nginx:latest
7c7f8bbb4ae732042b9ad3060d58f5c595f76fd7348b2b8e5beea857f74cf6e2
浏览器访问
采用域名劫持设置域名
顾名思义也就是修改物理机上的hosts文件来达到效果
修改hosts文件
后端业务jdk17、springboot
#拉取centos镜像
[root@docker--1 project_exam_system]# docker pull centos
#回到根目录
[root@docker--1 project_exam_system]# cd
#拖拽项目资源和jdk17版本的文件
#项目资源：application.properties
