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 -Erz waiting to receive.[root@docker--1 ~]# lsanaconda-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
EOFmodprobe overlaymodprobe br_netfiltercat << 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
EOFsysctl --systemyum install -y yum-utils device-mapper-persistent-data lvm2yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repoyum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y2.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 nginxUsing default tag: latestlatest: Pulling from library/nginxDigest: sha256:447a8665cc1dab95b1ca778e162215839ccbb9189104c79d7ec3a81e14577addStatus: Image is up to date for nginx:latestdocker.io/library/nginx:latest4.查看镜像
[root@docker3 ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEnginx latest 5ef79149e0ec 2 weeks ago 188MB5.创建nginx容器
[root@docker--1 ~]# docker run -itd -p80:80 nginx:latest a9200f608c60aa1c8827b5562b7906d543d48e38c06f76bdb1b702ce73209117
[root@docker--1 ~]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS NAMESa9200f608c60 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 andworking. Further configuration is required.</p><p>For online documentation and support please refer tonginx.org.<br/>Commercial support is available atnginx.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 -Erz waiting to receive.[root@docker--1 web]# lsdist.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]# lsdist 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
