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
