docker搭建lnmp环境步骤（win10家庭版）

避坑！用docker搭建php开发环境，希望能给同样有需要搭建环境的同学起到一些帮助，少踩一些坑。

1、下载用到的镜像

docker pull php:7.2-fpm
docker pull mysql
docker pull nginx

2、创建相应容器

1、安装顺序，php->nginx->mysql
#由于docker运行的VM里边setting中Shared Folder中只有c/Users，挂载文件放到c:/users 目录下可以了
#复制文件时使用C:/Users/zxwen_zl,挂载时使用 /c/Users/zxwen_zl

2、安装php
    docker run --name php -d php:7.2-fpm
    #复制配置文件
    docker cp php:/usr/local/etc/php-fpm.d/www.conf C:/Users/zxwen_zl/docker/php-conf/www.conf
    docker cp php:/usr/local/etc/php/php.ini-production C:/Users/zxwen_zl/docker/php-conf/php.ini 
    docker kill php
    docker rm php
    docker run --name php -v /c/Users/zxwen_zl/docker/www:/var/www/html -v /c/Users/zxwen_zl/docker/php-conf/www.conf:/usr/local/etc/php-fpm.d/www.conf -v /c/Users/zxwen_zl/docker/php-conf/php.ini:/usr/local/etc/php/php.ini -d php:7.2-fpm
    
3、安装nginx
    docker run --name nginx -p 80:80 -d -v /c/Users/zxwen_zl/docker/www:/var/www/html -d nginx
    #复制配置文件
    docker cp nginx:/etc/nginx/conf.d C:/Users/zxwen_zl/docker/nginx-conf/conf.d
    docker kill nginx
    docker rm nginx
    docker run --name nginx -p 80:80 -v /c/Users/zxwen_zl/docker/www:/var/www/html -v  /c/Users/zxwen_zl/docker/nginx-conf/conf.d:/etc/nginx/conf.d/ --link php:php -d nginx
    
    #修改/c/Users/zxwen_zl/docker/nginx-conf/conf.d/default.conf
    server {
        listen       80;
        listen  [::]:80;
        server_name  localhost;
        root   /var/www/html;   //修改根目录
    
        #charset koi8-r;
        access_log  /var/log/nginx/host.access.log  main;   //打开访问日志
        error_log  /var/log/nginx/host.error.log  warn;     //打开错误日志
    
        location / {        
            index  index.html index.htm index.php;
        }
    
        #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_pass   php:9000;        //指向端口9000上的主机名php
            fastcgi_index  index.php;
            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;
        }
    }
    
    修改完重启nginx容器  docker restart nginx
    或在nginx容器  service nginx reload
    
    
4、安装mysql
    docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /d/docker/mysql/data:/var/lib/mysql -v /d/docker/mysql/conf:/etc/mysql/conf.d -d  --privileged=true mysql
    #mysql安装到c盘会报错，启动不了，放到了d盘
        
5、打开/c/Users/zxwen_zl/docker/www创建index.php文件（phpinfo）

6、访问地址：ip/index.php
    看到phpinfo页面，大功告成！！！

3、报错问题列表

1、WIN10下 docker报错Error response from daemon: invalid mode
解决办法：docker挂载目录不能使用D:/docker这种写法，正确写法：/d/docker

2、访问报错
FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost"
解决方法：1、nginx配置文件
fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
改为
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

或2、查看php并入到nginx里，即配置nginx时是否使用 --link php:php（当初这个问题找了一天才发现）

3、访问报错
upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.33.1, server: waiter-host.chuchujie.com, request: "GET /admin.php?s=/Index/test HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "waiter-host.chuchujie.com"
解决办法：nginx配置文件，
fastcgi_pass   127.0.0.1:9000;
改为
fastcgi_pass   php:9000;
