前言

注意：搞docker的环境时，切记把firewalld和selinux关了，否则docker很多服务会起不来

一、dockerfile撰写php镜像

FROM centos:7.4.1708
ENV TIME_ZOME Asia/Shanghai
ARG WJ="php-7.1.10"
ADD $WJ.tar.bz2 /opt
RUN yum -y install gcc gcc-c++ make gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel bison \\
    && mkdir -p /usr/local/php/etc \\
    && cd /opt/$WJ \\
    && ./configure --prefix=/usr/local/php \\
        --with-config-file-path=/usr/local/php/etc \\
        --with-gd --with-mysqli \\
        --with-openssl --with-zlib --with-curl \\
        --with-jpeg-dir --with-png-dir --with-iconv \\
        --enable-fpm --enable-zip --enable-mbstring \\
    && make -j 2 \\
    && make install \\
    && cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf \\
    && cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf \\
    && sed -i '/;daemonize/a\\daemonize = no' /usr/local/php/etc/php-fpm.conf \\
    && sed -i 's/127.0.0.1/0.0.0.0/g' /usr/local/php/etc/php-fpm.d/www.conf \\
    && echo "${TIME_ZOME}" > /etc/timezone \\
    && ln -sf /usr/share/zoneinfo/${TIME_ZOME} /etc/localtime \\
    && rm -rf /opt/local/php* \\
    && yum clean all \\
    && yum -y remove gcc gcc-c++ make \\
    && mkdir -p /usr/local/nginx/html \\
    && echo -e "<?php\\nphpinfo();\\n?>" > /usr/local/nginx/html/index.php

WORKDIR /usr/local/php/
EXPOSE 9000
CMD ["sbin/php-fpm","-c","etc/php-fpm.conf"]

文件结构：

创建php镜像：

二、dockerfile撰写mysql镜像

FROM centos:7.4.1708
ADD mysql-5.6.26.tar.gz /opt
RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo \\
    &&  useradd -s /sbin/nologin mysql \\
    && yum -y install gcc gcc-c++ make pcre-devel expat-devel perl ncurses-devel autoconf cmake \\
    && cd /opt/mysql-5.6.26/ \\
    && cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DSYSCONFIDIR=/etc -DMYSQL_DATADIR=/home/mysql/ -DMYSQL_UNIX_ADDR=/home/mysql/mysql.sock \\
    && make -j2 \\
    && make install \\
    && cp -f support-files/my-default.cnf /etc/my.cnf \\
    && cp support-files/mysql.server /etc/init.d/mysqld \\
    && chown -R mysql:mysql /usr/local/mysql/ \\
    && sed -i 's/^basedir/basedir=\\/usr\\/local\\/mysql/g' /etc/init.d/mysqld \\
    && sed -i 's/^datadir/datadir=\\/home\\/mysql/g' /etc/init.d/mysqld \\
    && /usr/local/mysql/scripts/mysql_install_db --user=mysql --ldata=/var/lib/mysql --basedir=/usr/local/mysql --datadir=/home/mysql
ENV PATH /usr/local/mysql/bin:$PATH
EXPOSE 3306
ENTRYPOINT ["/usr/local/mysql/bin/mysqld_safe"]

文件结构：

创建mysql镜像：

三、dockerfile撰写nginx镜像

FROM centos:7.4.1708
ADD nginx-1.12.0.tar.gz /opt
RUN yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make \\
    && useradd -M -s /sbin/nologin nginx \\
    && cd /opt/nginx-1.12.0/ \\
    && ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-file-aio --with-http_gzip_static_module --with-http_flv_module --with-http_ssl_module \\
    && make \\
    && make install \\
    && ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx \\
    && echo -e "events {\\nuse epoll;\\nworker_connections  1024;\\n}\\nhttp {\\nserver_tokens on;\\nserver {\\nlisten       80;\\nserver_name  localhost;\\nlocation / {\\nroot   html;\\nindex  index.html index.htmi index.php;\\n}\\nerror_page   500 502 503 504  /50x.html;\\nlocation = /50x.html {\\nroot   html;\\n}\\nlocation ~ \\.php$ {\\nroot           html;\\nfastcgi_pass   172.168.184.30:9000;\\nfastcgi_index  index.php;\\nfastcgi_param  SCRIPT_FILENAME  \\$document_root\\$fastcgi_script_name;\\ninclude        fastcgi_params;\\n}\\n}\\n}" > /usr/local/nginx/conf/nginx.conf 
ENV PATH /usr/local/nginx/sbin:$PATH
WORKDIR /usr/local/nginx/
EXPOSE 80
CMD ["nginx","-g","daemon off;"]

文件结构：

创建mysql镜像：

四、查看镜像构建情况

五、分别开启nginx、mysql和php镜像

六、进行测试
