DNMP:基于docker搭建集成LNMP（nginx+mysql+php）

有一天，主机商跑路了。迫于无奈之下，我需要进行数据迁移。原先用的主机我可以什么都不管，直接用就行。而现在，只有一个centos服务器。一切从零开始...

我曾试过一个一个安装，从docker入手，一步一步搭建mysql,nginx,php。正当我即将看到胜利的曙光时，现实又给了我当头一棒。php扩展没有pdo_mysql，php.ini配置文件找不到等等。各种问题接踵而至。我曾多次想过放弃。不知道到底哪个环节出错了，如果让我从新再来，想想就让人心生疲惫。直到我看到了这个： DNMP(LNMP)一键安装程序 。注意：这不是广告，亲测，亲测。

我们先初步了解下他的强大之处：

 好家伙，口气还真不小。事实是否真就如此呢。我们就来动手实操一番。是骡子是马拉出来溜溜。我们就按照他的要求，一步步操作。

1.准备工作（docker+docker-compose 1.7以上+git）

docker安装就不多加叙述，根据服务器系统的不同，百度一下对应的安装命令即可。

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

 国内 daocloud 一键安装命令：

curl -sSL https://get.daocloud.io/docker | sh

 

安装完之后可以输入：docker -version查看版本。 

docker-compose安装命令：先确定安装目录。我这里打算安装到home目录下的dnmp子目录：

下载docker-compose命令：要安装其他版本的 Compose，请替换 v2.2.2。

$ sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

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

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

 至此docker和docker-compose已安装完成，而git只是为了clone项目。我们可以直接选择去git下载即可。这里就不安装了。下载完之后的目录结构如下：

 我们将文件上传到dnmp目录下，这里我是通过xftp上传的。

 2.启动项目

 第一步和第二步我们已经完成，第三步不用管，现在我们直接进行第四步，继续终端：依次输入命令，别忘了启动docker,启动命令：start docker.service

[root@localhost dnmp]# docker-compose --version
Docker Compose version v2.2.2
[root@localhost dnmp]# ls
bash.alias.sample  data  docker-compose.sample.yml  env.sample  LICENSE  logs  README-en.md  README.md  services  snapshot.png  www
[root@localhost dnmp]# cp env.sample .env
[root@localhost dnmp]# cp docker-compose.sample.yml docker-compose.yml
[root@localhost dnmp]# docker-compose up

 至此，基于docker的lnmp集成环境就安装完成啦~~，让我们奔放一下~

 very good !!!接下来就是自由发挥时间了，根据说明，我们可以更换mysql版本和php版本以及php扩展，另外，该集成还自备https。这就很nice了。下面我们继续深入一下。

3.数据库

数据库一共有两个版本，第一个是mysql8.0，第二个是mysql5.7，集成环境默认搭建的配置是：

 如果要下载其他的php版本或者mysql版本，找到dnmp目录下的docker-compose.yml配置文件，把前面的#号去掉皆可，再使用命令 docker-compose up创建启动一下就行了。数据库的默认用户名root,密码123456。

注意：另外下载的mysql5.7对应的端口为3305

 通过docker进入mysql，修改密码sql语句如下：两个用户都修改

[root@localhost ~]# docker ps

4.nginx静态配置

lz的项目是thinkphp5.0的，有两个，分别位于站点根目录www/api/tp5和www/dream。

dnmp/services/nginx/conf.d文件夹下的localhost.conf配置如下：

server {
    listen       80  default;
    server_name  localhost;
    root   /www/localhost;
    index  index.php index.html index.htm;
    #charset koi8-r;
    
    access_log /dev/null;
    #access_log  /var/log/nginx/nginx.localhost.access.log  main;
    error_log  /var/log/nginx/nginx.localhost.error.log  warn;
    
    #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

    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .+\.php($|/){
        fastcgi_pass   php:9000;

        index index.php;
        #如果文件不存在则尝试TP解析
        if (!-e $request_filename) {
           rewrite  ^/api/tp5/public/(.*)$  /api/tp5/public/index.php?s=/$1  last;
           break;
        }
    }
location /dream/public/ {
        index index.php;
        #如果文件不存在则尝试TP解析
        if (!-e $request_filename) {
           rewrite  ^/dream/public/(.*)$  /dream/public/index.php?s=/$1  last;
           break;
        }
    }

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

server {
    listen 443  default ssl http2;
    server_name  localhost;
    root   /www/localhost;
    index  index.php index.html index.htm;
    #charset koi8-r;

    access_log /dev/null;
    #access_log  /var/log/nginx/nginx.localhost.access.log  main;

    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_pass   php:9000;
        include        fastcgi-php.conf;
        include        fastcgi_params;
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
location /api/tp5/public/ {
        index index.php;
        #如果文件不存在则尝试TP解析
        if (!-e $request_filename) {
           rewrite  ^/api/tp5/public/(.*)$  /api/tp5/public/index.php?s=/$1  last;
           break;
        }
    }
location /dream/public/ {
        index index.php;
        #如果文件不存在则尝试TP解析
        if (!-e $request_filename) {

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

 5.配置SSL

这个就不多说了dnmp/services/ngin/ssl/localhost文件下的两个证书文件替换成自己的就行。

 

以上，就是docker安装集成环境的全部步骤，lz一路摸索一路爬坑。索性，幸不辱命！！
