（全栈学习实践）三、创建php、添加扩展，其他Dockerfile编写

摘要：一测试在官方的基础上简化基础镜像阿里源维护者信息添加扩展这里目标，这里是在运行上面镜像的容器测试得到结果，部分需要自行下载的插件或交互式安装的，使用多带带下载源码编译的方式。

一、测试PHP
1、在官方的基础上简化：

# php7.3.5; Feb 7, 2019 link: https://github.com/docker-library/php/blob/master/7.3/alpine3.9/fpm/Dockerfile
# Base images 基础镜像+阿里源
FROM alpine:3.9

# dependencies required for running "phpize"
ENV PHP_VERSION 7.3.6
ENV PHP_URL https://secure.php.net/get/php-$PHP_VERSION.tar.xz/from/this/mirror
ENV PHPIZE_DEPS 
        autoconf 
        dpkg-dev dpkg 
        file 
        g++ 
        gcc 
        libc-dev 
        make 
        pkgconf 
        re2c
ENV PHPIZE_DEVS 
        argon2-dev 
        coreutils 
        curl-dev 
        libedit-dev 
        libsodium-dev 
        libxml2-dev 
        openssl-dev 
        sqlite-dev 
        libjpeg-turbo-dev 
        libpng-dev 
        gd-dev 
        gettext-dev 
        freetype-dev 
        libxpm-dev 
        libevent-dev

RUN sed -i "s/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g" /etc/apk/repositories 
    && apk update 
    && addgroup -g 82 -S www-data 
    && adduser -u 82 -D -S -G www-data www-data 
    && mkdir -p "/usr/local/etc/php/conf.d" && mkdir -p "/var/www/html" 
    && chown www-data:www-data /var/www/html && chmod 777 /var/www/html 
    && apk add --no-cache
        curl 
        tar 
        xz 
        openssl 
        wget 

COPY php.tar.xz php.tar.xz
RUN set -eux; 
        apk add $PHPIZE_DEPS $PHPIZE_DEVS 
            
        # && wget -O php.tar.xz "$PHP_URL" 
        && tar -Jxf php.tar.xz && cd php-$PHP_VERSION && ./configure 
        --prefix="/usr/local/php" 
        --with-config-file-path="/usr/local/php/etc" 
        --with-config-file-scan-dir="/usr/local/php/etc/conf.d" 
        
        --enable-option-checking=fatal 
        --with-mhash 
        
        --enable-ftp 
        --enable-exif 
        --enable-mbregex 
        --enable-mbstring 
        --enable-mysqlnd 
        --enable-sysvmsg 
        --enable-opcache 
        --enable-pcntl 
        --enable-sockets 
        --enable-sysvsem 
        --enable-xml 
        --with-curl 
        --with-libedit 
        --with-openssl 
        --with-zlib 
        --with-pcre-regex 
        --with-pear 
        --with-libxml-dir=/usr 
        --with-jpeg-dir 
        --with-freetype-dir 
        --with-xpm-dir 
        --with-png-dir 
        --with-gettext 
        --with-mhash 
        --with-iconv 
        --disable-fileinfo 
        
        --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data --disable-cgi 
    && make -j "$(nproc)" 
    && find -type f -name "*.a" -delete 
    && make install 
#    && make clean 
    && rm -rf /tmp/pear ~/.pearrc 
    && cd ../ && rm -rf php-$PHP_VERSION.tar.xz php-$PHP_VERSION

2、添加扩展：
这里目标 swoole-inotify-redis-uuid-memcached，这里是在运行上面镜像的容器测试得到结果，部分需要自行下载的插件或交互式安装的，使用多带带下载源码编译的方式。/usr/local/php/etc/文件夹需要准备一个共享，这里取上面官方的配置稍加修改，并共享出来供后续安装使用：

[]:~/tmp/dk# tree -a php
php
├── config
│   ├── pear.conf
│   ├── php-fpm.conf
│   ├── php-fpm.conf.default
│   ├── php-fpm.d
│   │   ├── www.conf
│   │   └── www.conf.default
│   ├── php.ini
│   └── start.sh
├── Dockerfile
└── php.tar.xz 

测试shell到Dockerfile的代码。其中在安装memcached(相当于是memcache的新版、强化版)时遇到问题，官方memcached很快安装成功但php扩展难装：多次出现编译错误，php的memcached报缺libmemcached，而后者总是无法通过
参考《错误解决》，使用其中的参考自:https://bugs.launchpad.net/li...

Bug Description
When building with latest GCC version 7
----------

clients/memflush.cc:42:22: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
   if (opt_servers == false)
                      ^~~~~
clients/memflush.cc:51:24: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
     if (opt_servers == false)
                        ^~~~~

Trivial fix:
http://pkgs.fedoraproject.org/cgit/rpms/libmemcached.git/plain/libmemcached-build.patch
#打补丁，兴奋半天没有效果
http://pkgs.fedoraproject.org/cgit/rpms/libmemcached.git/plain/libmemcached-build.patch
patch -p0 < libmemcached-build.patch

最终使用 apk add libmemcached-dev 安装成功！！！（apk add libmemcached，或search的各版本都不行，只要一个dev）

#测试

#swoole 需要对话参数，所以自定义安装
RUN set -ex && 
    mkdir -p ~/build/swoole &&

    #测试命令：/usr/bin/memcached -d -m 1024 -u root -l 0.0.0.0 -p 11211 -c 1024 -P /tmp/memcached.pid 启动正常
    mkdir -p ~/build/memcached && 
    cd ~/build/memcached && 
    wget -O memcached.tgz "http://memcached.org/files/memcached-1.5.16.tar.gz" && 
    tar -zxf memcached.tgz --strip-components 1 && 
    ./configure --with-event-libevent-dir=/usr --prefix=/usr && 
    make && make install && 
    cd ../ && rm -rf memcached* && 
    
    #需要libmemcached
    apk add libmemcached-dev &&

    ./configure --with-php-config=/usr/local/php/bin/php-config && 
    make && make install && 
    cd ../ && rm -rf memcached_p*

#编译使用，运行时共享 -v /your_real_path/ /usr/local/php/etc/
COPY config /usr/local/php/etc
VOLUME ["/usr/local/php/etc","/var/www/html"]

RUN set -ex 
    && /usr/local/php/bin/pecl channel-update pecl.php.net 
    && /usr/local/php/bin/pecl install igbinary event 
    && /usr/local/php/bin/php -m

3、合并，再添加

CMD ["/usr/local/php/etc/start.sh"]
