Docker Dockefile制作nginx php镜像搭建WordPress网站

[root@localhost _data]# cd /nginx/ [root@localhost _data]# cd /nginx/ [root@localhost nginx]# ls Dockerfile nginx-1.15.5.tar.gz nginx.conf php.conf #这里nginx.conf需要COPY拷贝到编译好的nginx替换掉其默认配置文件，php.conf文件是为了搭建wordpress博客网站使用的虚拟主机配置文件

Dockerfile

[root@localhost nginx]# cat Dockerfile FROM ansible/centos7-ansible LABEL maintainer Complicated RUN yum install -y gcc gcc-c++ make \ openssl-devel pcre-devel gd-devel \ iproute net-tools telnet wget curl && \ yum clean all && \ rm -rf /var/cache/yum/* ADD nginx-1.15.5.tar.gz / RUN cd /nginx-1.15.5 && \ ./configure --prefix=/usr/local/nginx \ --with-http_ssl_module \ --with-http_stub_status_module && \ make -j 4 && make install && \ mkdir /usr/local/nginx/conf/vhost && \ cd / && rm -rf nginx* && \ ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime ENV PATH $PATH:/usr/local/nginx/sbin COPY nginx.conf /usr/local/nginx/conf/nginx.conf WORKDIR /usr/local/nginx EXPOSE 80 CMD ["nginx", "-g", "daemon off;"] （1）将依赖包和调试工具全部安装上，清理其环境。清理yum的缓存 （2）软连接一个上海时区到当前时区 （3）这里采用了nginx前台启动的命令，如果直接执行nginx这条命令，那么就是放在后台运行。这里加上了参数-g daemon off表示禁止后台启动。所以前台启动就是hang住容器。这样容器启动就不会被退出。

nginx.conf

[root@localhost nginx]# cat nginx.conf user nobody; worker_processes 4; worker_rlimit_nofile 65535; error_log logs/error.log notice; pid /var/run/nginx.pid; events { use epoll; worker_connections 4096; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log off; keepalive_timeout 65; client_max_body_size 64m; include /usr/local/nginx/conf/vhost/*.conf; #这个配置了一个虚拟主机来进行博客搭建 server { listen 80; server_name localhost; index index.html; location / { root html; } } }

这里就不看虚拟主机的配置信息了，后面可以看到，就直接制作镜像了

PHP项目镜像构建：PHP

#这里就没有像nginx一样需要把自己的配置文件COPY进去，但是还是需要编译和nginx没多大区别 [root@localhost ~]# cd /php/ [root@localhost php]# ls Dockerfile php-5.6.36.tar.gz

[root@localhost php]# cat Dockerfile FROM ansible/centos7-ansible LABEL MAINTAINER Complicated RUN yum install epel-release -y && \ yum install -y gcc gcc-c++ make gd-devel libxml2-devel \ libcurl-devel libjpeg-devel libpng-devel openssl-devel \ libmcrypt-devel libxslt-devel libtidy-devel autoconf \ iproute net-tools telnet wget curl && \ yum clean all && \ rm -rf /var/cache/yum/* ADD php-5.6.36.tar.gz / RUN cd /php-5.6.36 && \ ./configure --prefix=/usr/local/php \ --with-config-file-path=/usr/local/php/etc \ --enable-fpm --enable-opcache \ --with-mysql --with-mysqli --with-pdo-mysql \ --with-openssl --with-zlib --with-curl --with-gd \ --with-jpeg-dir --with-png-dir --with-freetype-dir \ --enable-mbstring --with-mcrypt --enable-hash && \ make -j 4 && make install && \ cp php.ini-production /usr/local/php/etc/php.ini && \ cp sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf && \ sed -i "90a \daemonize = no" /usr/local/php/etc/php-fpm.conf && \ mkdir /usr/local/php/log && \ cd / && rm -rf php* && \ ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime ENV PATH $PATH:/usr/local/php/sbin COPY php.ini /usr/local/php/etc/ COPY php-fpm.conf /usr/local/php/etc/ WORKDIR /usr/local/php EXPOSE 9000 CMD ["php-fpm"] （1）可以看到和nginx的Dockerfile大致相同 （2）Make -j 4指定编译时候的线程数，如果是多核CPU可以将其值调大。这样编译速度会更加快一些 （3）这个指令是在前台运行的，就是不加任何参数在前台运行。也是使用CMD去启动就行。在写Dokcefile的时候大部分情况下使用CMD启动就行。
