单机编排LNMP+Harbor+WeaveScope

一、架构图

二、目的

使用docker-compose单机编排lnmp环境，并实现iWebShop商城发布。且镜像推送到私有仓库，后期编排更加方便。最后部署Weave Scope监控容器。

三、Harbor仓库安装

harbor安装需要使用docker-compose

安装docker-compose

[root@harbor ~]# yum install epel-release -y

[root@harbor ~]# yum install python-pip -y

[root@harbor ~]# pip install docker-compose

[root@harbor ~]# docker-compose --version

docker-compose version 1.24.0, build 0aa5906

部署Harbor

[root@harbor ~]# tar xf harbor-offline-installer-v1.8.0.tgz.tar  -C /usr/local

修改配置文件

[root@harbor ~]# vim /usr/local/harbor/harbor.yml

hostname = 192.168.231.32  #设置主机名

刷新配置文件

[root@harbor ~]# /usr/local/harbor/prepare

进行安装

[root@harbor ~]# /usr/local/harbor/install.sh

✔ ----Harbor has been installed and started successfully.----

​ ​

配置docker

添加不安全的注册，否则不能推送进行，需要配置https

[root@harbor ~]# vim /etc/docker/daemon.json

{
"registry-mirrors": ["https://xxxx.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.231.32"]
}

重启docker

[root@harbor ~]# systemctl restart docker

浏览器访问

输入主机ip，用户名和密码默认为：admin,Harbor12345

​ ​

​

新建仓库

​ ​

lnmp服务器推送镜像进行测试

配置docker

[root@lnmp ~]# cat /etc/docker/daemon.json

{
"registry-mirrors": ["https://xxxx.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.231.32:80"]
}

重启docker

[root@lnmp ~]# systemctl restart docker

给镜像打标签

[root@lnmp ~]# docker tag centos:7 192.168.231.32/real/centos:7

登录私有镜像库

[root@lnmp ~]# docker login 192.168.231.32

Username: admin

Password:

WARNING! Your password will be stored unencrypted in /root/.docker/config.json.

Configure a credential helper to remove this warning. See

https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

推送镜像

[root@lnmp ~]# docker push 192.168.231.32/real/centos:7

三、nginx安装

[root@lnmp ~]# mkdir -p lnmp/{nginx,mysql,php}

[root@lnmp ~]# mkdir -p lnmp/nginx/{html,conf.d,log}

docker-compose编写

[root@lnmp lnmp]# cat docker-compose.yml

version: '2.2'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./nginx/html:/usr/share/nginx/html  #网页文件
      - ./nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf  #nginx配置文件
      - ./nginx/log:/var/log/nginx/  #nginx日志
    environment:
      - TZ=Asia/Shanghai
    container_name: "nginx"
    networks:
      - front
networks:
  front:

nginx配置文件

[root@lnmp ~]# cat lnmp/nginx/conf.d/default.conf

server {
   index index.php index.html;
   server_name php-docker.local;
   error_log  /var/log/nginx/error.log;
   access_log /var/log/nginx/access.log;
   root /usr/share/nginx/html;
}

创建index.html

[root@lnmp ~]# cat lnmp/nginx/html/index.html

welcome  to nginx

启动容器

[root@lnmp lnmp]# docker-compose up -d

访问测试

四、php安装

编写php的Dockerfile文件

[root@lnmp ~]# cat lnmp/php/Dockerfile

FROM php:7-fpm
COPY zhongkeda.list /etc/apt/sources.list
RUN  apt-get update && apt-get install -y  libfreetype6-dev libjpeg-dev libpng-dev  zlib1g-dev libzip-dev\
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd \
&& docker-php-ext-install mysqli \
&& docker-php-ext-install pdo_mysql \
&& docker-php-ext-install zip \
&& docker-php-ext-install sockets \
&& rm -r /var/lib/apt/lists/*

上边安装相关扩展，与mysql进行连接

创建debian镜像源

否则下载会很慢

[root@lnmp ~]# cat lnmp/php/zhongkeda.list

deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free 
deb-src http://mirrors.ustc.edu.cn/debian stable main contrib non-free 
deb http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free 
deb-src http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free

创建php镜像

[root@lnmp php]# pwd

/root/lnmp/php

[root@lnmp php]# docker build -t php:test .

给镜像打标签

[root@lnmp ~]# docker tag php:test 192.168.231.32/real/php:test

编写docker-compose.yml

[root@lnmp lnmp]# cat docker-compose.yml

version: '2.2'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./nginx/html:/usr/share/nginx/html
      - ./nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf
      - ./nginx/log:/var/log/nginx/
    depends_on:  #解决容器的依赖、启动先后的问题
      - php
    environment:
      - TZ=Asia/Shanghai
    container_name: "nginx"
    networks:
      - front
  php:
    image: 192.168.231.32/real/php:test
    volumes:
      - ./nginx/html:/usr/share/nginx/html
    container_name: "php"
    networks:
      - front

networks:
  front:

修改nginx的配置文件

使nginx和php连接

[root@lnmp lnmp]# cat nginx/conf.d/default.conf

server {
    index index.php index.html;
    server_name php-docker.local;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /usr/share/nginx/html;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

创建php文件

[root@lnmp lnmp]# cat nginx/html/index.php

重启项目中的服务

[root@lnmp lnmp]# docker-compose up -d

访问测试

五、mysql安装

编写docker-compose文件

添加

  mysql:
    image: mysql:5.6
    restart: always
    ports:
      - "3306:3306"
    environment:
      - TZ=Asia/Shanghai
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=iwebshop
    volumes:
      - ./mysql/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
      - ./mysql/data:/var/lib/mysql

    container_name: "mysql"
    networks:
      - front

创建相关文件

[root@lnmp ~]# mkdir lnmp/mysql/data/

[root@lnmp ~]# egrep -v "^$|#" lnmp/mysql/mysqld.cnf

[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket  = /var/run/mysqld/mysqld.sock
datadir  = /var/lib/mysql
log_bin  = mysql-bin
binlog_format = mixed
log-error = /var/log/mysql/error.log
symbolic-links=0

创建php文件进行测试

[root@lnmp lnmp]# cat nginx/html/index.php

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully";
    }
catch(PDOException $e)
    {
    echo "Connection failed: " . $e->getMessage();
    }
?>

编排

[root@lnmp lnmp]# docker-compose up -d

查看

[root@lnmp lnmp]# docker-compose ps

Name               Command              State           Ports        

----------------------------------------------------------------------

mysql   docker-entrypoint.sh mysqld     Up      0.0.0.0:3306->3306/tcp

nginx   nginx -g daemon off;            Up      0.0.0.0:80->80/tcp    

php     docker-php-entrypoint php-fpm   Up      9000/tcp    

访问测试

六、部署iWebShop商城

iWebShop包解压

[root@lnmp ~]# unzip iWebShop5.5临时试用版本.zip

[root@lnmp ~]# mv iWebShop5.5/* lnmp/nginx/html/

[root@lnmp ~]# mv upload.zip lnmp/nginx/html/upload

[root@lnmp ~]# unzip lnmp/nginx/html/upload/upload.zip

给其他用户添加写权限

[root@lnmp ~]# chmod o+w lnmp/nginx/html/*

[root@lnmp ~]# chmod o+w lnmp/nginx/html/config/*

浏览器进行安装

七、部署Weave Scope

Weave Cloud是一种可视化，管理和监控Docker容器的快速而简单的方法，使开发人员能够专注于编写代码。

编辑docker-compose.yml

添加

scope:
    image: weaveworks/scope:1.11.2
    network_mode: "host"  #此时容器使用本地主机的网络，它拥有完全的本地主机接口访问权限。
    pid: "host"   #跟主机系统共享进程命名空间。
    privileged: true  #允许容器中运行一些特权命令
    labels:
      - "works.weave.role=system"  #为容器添加 Docker 元数据（metadata）信息
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:rw"
    command:
      - "--probe.docker=true"

构建镜像并启动容器

[root@lnmp lnmp]# docker-compose up -d

查看

浏览器访问：

ip:4040

  监控本机的3个容器，包括其内存、CPU等

总：

version: '2.2'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./nginx/html:/usr/share/nginx/html
      - ./nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf
      - ./nginx/log:/var/log/nginx/
    depends_on:
      - php
    environment:
      - TZ=Asia/Shanghai
    container_name: "nginx"
    networks:
      - front
    restart: always
 
  php:

    volumes:
      - ./nginx/html:/usr/share/nginx/html
    environment:
      - TZ=Asia/Shanghai
    container_name: "php"
    networks:
      - front
      - back
  
  mysql:
    image: mysql:5.6 
    restart: always
    ports:
      - "3306:3306"
    environment:
      - TZ=Asia/Shanghai
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=iwebshop
    volumes:
      - ./mysql/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
      - ./mysql/data:/var/lib/mysql
    container_name: "mysql"
    networks:
      - back 
  scope:
    image: weaveworks/scope:1.11.2
    network_mode: "host"
    pid: "host"
    privileged: true
    labels:
      - "works.weave.role=system"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:rw"
    command:
      - "--probe.docker=true"
    
networks:
