docker环境部署nginx、tomcat、redis

centos7 部署docker###

官网部署地址

https://docs.docker.com/engine/install/centos/

1、移除旧版docker

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

2、安装依赖包

yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

3、配置阿里镜像源

yum-config-manager \
    --add-repo \
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4、安装最新docker

yum install docker-ce docker-ce-cli containerd.io
systemctl start docker
systemctl enable docker

5、运行hello-world镜像

docker run hello-world

6、配置阿里云加速

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://bmmh6qxh.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

7、如果docker命令无法自动补全安装bash-completion重新打开终端即可

yum install -y bash-completion

二、docker环境部署nginx###

1、进入docker hub，查看并下载相关镜像的版本，网址www.hub.docker.com；

docker pull nginx:latest

2、创建nginx配置文件目录并运行容器
mkdir -p /usr/local/nginx/conf/conf.d

docker run --name nginx -d nginx:latest

拷贝容器内nginx配置日志文件到宿主机

docker cp nginx:/etc/nginx/conf.d/default.conf  /usr/local/nginx/conf/conf.d 

docker cp nginx:/usr/share/nginx/html /usr/local/nginx/

docker cp nginx:/var/log/nginx /usr/local/nginx/logs/

docker stop nginx 

docker rm nginx

3、运行容器暴露端口，并将容器目录挂载至宿主机

docker run --name nginx -d -p 8002:80 \
-v /usr/local/nginx/html:/usr/share/nginx/html \  
-v /usr/local/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /usr/local/nginx/logs/nginx:/var/log/nginx/ nginx

4、使用浏览器打开nginx
