基于Dockerfile创建镜像LNMP+wordpress

实验组件

172.111.0.10：nginx		docker-nginx
172.111.0.20：mysql		docker-mysql
172.111.0.30：php   	docker-php

实验步骤

1.建立nginx-lnmp镜像及容器

cd /opt
mkdir nginx
cd nginx/
--上传nginx-1.22.0.tar.gz和wordpress-6.4.2-zh_CN.tar.gz--
vim Dockfile

FROM centos:7
RUN yum -y install gcc pcre-devel openssl-devel zlib-devel openssl openssl-devel
ADD nginx-1.22.0.tar.gz /usr/local/src/
RUN useradd -M -s /sbin/nologin nginx
WORKDIR /usr/local/src/nginx-1.22.0
RUN ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module && make -j 4 && make install
ENV PATH /usr/local/nginx/sbin:$PATH
COPY nginx.conf /usr/local/nginx/conf/
ADD wordpress-6.4.2-zh_CN.tar.gz /usr/local/nginx/html
RUN chmod -R 777 /usr/local/nginx/html
EXPOSE 80
VOLUME ["/usr/local/nginx/html/"]
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

cd /opt/nginx/
vim nginx.conf

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        charset utf-8;
        location / {
            root   html;
            index  index.html index.php;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        location ~ \.php$ {
            root           html;
            fastcgi_pass   172.111.0.30:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
            include        fastcgi_params;
        }
}
}

#自定义网段
docker network create --subnet=172.111.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork

#建立镜像
docker build -t nginx:lnmp .

#建立容器
docker run -itd --name nginx -p 80:80 -v /opt/nginx:/opt/nginxlogs --net mynetwork  --ip 172.111.0.10 nginx:lnmp

docker ps

#配置容器中nginx静态页面内容
docker exec -it nginx bash
echo this is nginx > /usr/local/nginx/html/index.htm

curl 20.0.0.10
浏览器访问20.0.0.10

2.建立mysql-lnmp镜像及容器

cd /opt
mkdir mysql
cd mysql/
--上传mysql-boost-5.7.20.tar.gz--
vim Dockerfile

FROM centos:7
RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make &&\
useradd -M -s /sbin/nologin  mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/
#指定工作目录：

make -j 4 && make install
COPY my.cnf /etc/my.cnf
#设置暴露端口
EXPOSE 3306
RUN chown -R mysql:mysql /usr/local/mysql && chown mysql:mysql /etc/my.cnf
WORKDIR /usr/local/mysql/bin/
RUN ./mysqld \
--initialize-insecure \

systemctl enable mysqld
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
VOLUME ["/usr/local/mysql"]
ENTRYPOINT ["/usr/sbin/init"]

cd /opt/mysql/
vim my.cnf

docker build -t mysql:lnmp .
docker run -itd --name mysql -p 3306:3306 --privileged -v /opt/mysql1:/opt/mysql --net mynetwork --ip 172.111.0.20 mysql:lnmp

docker exec -it mysql bash
mysql -u root -p
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by '123456';   
flush privileges; 

navicat访问：20.0.0.70

3.建立php-lnmp镜像及容器

mkdir php
cd php
--上传php-7.1.10.tar.bz2  php-fpm.conf  php.ini  www.conf--
vim Dockerfile

FROM centos:7

useradd -M -s /sbin/nologin nginx
ADD php-7.1.10.tar.bz2 /usr/local/src/
WORKDIR /usr/local/src/php-7.1.10
RUN ./configure \

make -j 4 && make install
ENV PATH /usr/local/php/bin:/usr/local/php/sbin:$PATH
COPY php.ini /usr/local/php/lib/
COPY php-fpm.conf /usr/local/php/etc/
COPY www.conf /usr/local/php/etc/php-fpm.d/
EXPOSE 9000
