docker随笔9--docker-compose安装lnmp环境

一个项目往往需要多个容器，容器与容器之间存在依赖关系，数量太多，启动是输入的命令太多，为了解决这些问题，采用docker-compose来完成，通过编写docker-compose.yml文件，启动项目，可以类比node里的package.json，执行编译只需npm build,docker-compose编译执行只需

docker-compose up -d

1.首先是安装docker-compose：

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

2.构建目录结构：

我的目录结构如下

----web:
 |
 |---------nginx
 |----------------conf
 |----------------vhost
 |----------------web
 |---------php
 |---------mysql 

3.下面是关于docker-compose的参数说明：

version : "3" #docker-compose的版本
services: #容器的集合
        mysql: #项目名称
                image: mysql:5.7 #镜像名称，如果是通过dockerfile创建的可以使用build属性
                container_name: mysql  #容器名称，如果没有这个属性的话，docker-compose会随机分配一个名字给容器
                privileged: true    #允许操作的表示，如果不加的话会出现类似，permission deny的错误
                ports:
                        - 3307:3306  #开放宿主机和容器的映射端口
                environment:
                        MYSQL_ROOT_PASSWORD: root  #mysql镜像中的环境变量
        php:
                 image: php:7.2-fpm
                 container_name: php
                 privileged: true
                 ports: 
                        - 9001:9000
                 links:
                         - mysql  #容器之间进行关联

                 volumes:
                         - /docker/wwwroot:/www/web  #挂载卷，需要注意的是，php在以模块的形式加载到nginx的时候，需要他们两个的目录结构一致，否则nginx无法加载php,但是 html等静态问价可以正常访问。

        nginx:
                 image:  nginx
                 container_name: nginx
                 privileged: true
                 links:
                         - php
                 ports:
                         - 8088:80
                 volumes:
                         - ./nginx/vhost:/www/nginx/vhost
                         - ./nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro
                         - ./nginx/log:/www/nginx/log
                         - /docker/wwwroot:/www/web

        phpmyadmin:
                image: phpmyadmin/phpmyadmin
                container_name: phpmyadmin
                privileged: true
                links:
                        - mysql
                ports: 
                        - 7001:80
                environment:
                        MYSQL_ROOT_PASSWORD: root
                        PMA_HOST: mysql

        redis: 
                image: redis:4.0.14
                container_name: redis
                privileged: true
                ports:
                        - 6379:6379
        mongo:
                image: mongo
                restart: always
                ports:
                        - 27017:27017

 

4.修改nginx.conf配置：

user  nginx;
worker_processes  1;

error_log  /www/nginx/log/error.log warn;
pid        /www/nginx/log/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /www/nginx/log/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /www/nginx/vhost/*.conf;
}

5.修改default.conf配置

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
    root    /www/web;
    location / {
        index  index.html index.htm index.php;
    try_files $uri $uri/ $uri.php?$args;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        
        fastcgi_index  index.php;
        fastcgi_pass   php:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;    
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

 

6.访问localhost:8088端口，并在web目录下新增test.php，通过localhost:8088/test 访问
