-----------------安装 Docker---------------------------
目前 Docker 只能支持 64 位系统。
systemctl stop firewalld.service
setenforce 0
#安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
--------------------------------------------------------------------------------------------
yum-utils:提供了 yum-config-manager 工具。
device mapper: 是Linux内核中支持逻辑卷管理的通用设备映射机制,它为实现用于存储资源管理的块设备驱动提供了一个高度模块化的内核架构。
device mapper存储驱动程序需要 device-mapper-persistent-data 和 lvm2。
--------------------------------------------------------------------------------------------
#设置阿里云镜像源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#安装 Docker-CE并设置为开机自动启动
yum install -y docker-ce docker-ce-cli containerd.io
systemctl start docker.service
systemctl enable docker.service
--------------------------------------------------------------------------------------------
安装好的Docker系统有两个程序,Docker服务端和Docker客户端。其中Docker服务端是一个服务进程,负责管理所有容器。 Docker客户端则扮演着Docker服务端的远程控制器,可以用来控制Docker的服务端进程。大部分情况下Docker服务端和客户端运行在一台机器上。

使用标签"nginx:lnmp"构建Docker镜像
docker build -t nginx:lnmp .
启动镜像:
docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp
#-d在后台启动一个名为"nginx"的Docker容器。它将主机的80端口映射到容器的80端口(-p 80:80)。它还将主机上的目录/opt/nginx/html挂载到容器中的/usr/local/nginx/html目录(-v /opt/nginx/html:/usr/local/nginx/html)。容器连接到名为"mynetwork"的网络(--net mynetwork),并分配IP地址172.18.0.10(--ip 172.18.0.10)。容器基于镜像"nginx:lnmp"。

创建php:lnmp镜像
docker build -t php:lnmp .
启动镜像
docker run --name=php -d -p 9000:9000 --volumes-from mysql --volumes-from nginx --net mynetwork --ip 172.18.0.30 php:lnmp
进入mysql容器:
docker exec -it mysql /bin/bash
mysql
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
flush privileges;
浏览器访问:
http://20.0.0.106/wordpress/index.php
注意如果登不上,讲wp-config.php 配置文件写入用户名 及其密码,随后重启nginx容器
二、使用docker-compose 搭建lnmp
- Docker Compose 环境安装
Docker Compose 是 Docker 的独立产品,因此需要安装 Docker 之后在单独安装 Docker Compose
#下载
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
或者直接将compose的包放入 /usr/local/bin/下
#安装
chmod +x /usr/local/bin/docker-compose
#查看版本
docker-compose --version
准备依赖文件:
mkdir /opt/compose_lnmp/
cd /compose_lnmp
nginx mysql php
同上:在相应的目录内编写Dockerfile文件!!
写完相对应的Dockerfile文件后编写docker-compose.yml文件
#定义docker-compose版本,可以是2 或 3
version: '3'
#使用services定义服务
services:
#第一个service
nginx:
#设置容器名
container_name: nginx
#使用dockerfile来构建镜像
build:
#指定Dockerfile文件所在位置
context: ./nginx
#指定文件名
dockerfile: Dockerfile
#映射端口
ports:
- 80:80
- 443:443
#设置数据卷挂载
volumes:
- ./nginx/html:/usr/local/nginx/html
#加入网络
networks:
lnmp:
ipv4_address: 172.18.0.10
mysql:
container_name: mysql
build:
context: ./mysql
dockerfile: Dockerfile
ports:
- 3306:3306
networks:
lnmp:
ipv4_address: 172.18.0.20
volumes:
- db-data:/usr/local/mysql
privileged: true
php:
container_name: php
build:
context: ./php
dockerfile: Dockerfile
ports:
- 9000:9000
networks:
lnmp:
ipv4_address: 172.18.0.30
volumes:
- db-data:/usr/local/mysql
- ./nginx/html:/usr/local/nginx/html
depends_on:
- nginx
- mysql
#设置网络为自定义网络
networks:
lnmp:
driver: bridge
ipam:
config:
- subnet: 172.18.0.0/16
volumes:
db-data:
最后在后台启动 Docker Compose 项目:
docker-compose -f docker-compose.yml up -d
随后进入mysql 容器:
docker exec -it mysql /bin/bash
mysql
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
flush privileges;
浏览器访问:
http://20.0.0.106/wordpress/index.php
cd /opt/compose_nginx/nginx/html/wordpress
vim wp-config.php
