#1，数据源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#2， 更新yum软件包索引
yum makecache fast
3，安装docker ce
yum -y install docker-ce
#报错 Problem: package docker-ce-3:20.10.0-3.el7.x86_64 requires containerd.io >= 1.4.1, but none of the providers can be installed

dnf install https://download.docker.com/linux/centos/8/x86_64/stable/Packages/containerd.io-1.4.3-3.1.el8.x86_64.rpm
#安装1.4.3-3.1包 遇到以下报错的话

yum -y install docker-ce
#开机自启

systemctl start docker.service

#docker 安装nginx
docker pull nginx:1.10

随便启动一个nginx实例，只是为了复制出配置，放到docker里作为镜像的统一配置

docker run -p 80:80 --name nginx -d nginx:1.10

cd /mydata/nginx

注意这个点

docker container cp nginx:/etc/nginx .
#然后在外部 /mydata/nginx/nginx 有了一堆文件
mv /mydata/nginx/nginx /mydata/nginx/conf

停掉nginx

docker stop nginx
docker rm nginx

创建新的nginx

docker run -p 80:80 --name nginx
-v /mydata/nginx/html:/usr/share/nginx/html
-v /mydata/nginx/logs:/var/log/nginx
-v /mydata/nginx/conf:/etc/nginx
-d nginx:1.10

注意一下这个路径映射到了/usr/share/nginx/html，我们在nginx配置文件中是写/usr/share/nginx/html，不是写/mydata/nginx/html

docker update nginx --restart=always

拉取镜像

docker pull nacos/nacos-server

挂载目录

mkdir -p /mydata/nacos/logs/                      #新建logs目录
mkdir -p /mydata/nacos/init.d/          
vim /mydata/nacos/init.d/custom.properties        #修改配置文件

mysql新建nacos的数据库，并执行脚本
