本文主要是介绍Dockerfile镜像搭建LNMP，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、环境准备

1、关闭防火墙
systemctl status firewalld.service
setenforce 0

2、拉取centos:7镜像
docker pull centos:7

3、自定义网络
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1"  mynetwork

二、部署nginx（容器IP 为 172.18.0.10）

mkdir /opt/nginx
cd /opt/nginx/

上传 nginx-1.12.2.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中
mkdir /opt/nginx/html
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

vim Dockerfile

FROM centos:7
MAINTAINER this is nginx image <lsq>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.2.tar.gz /usr/local/src/
WORKDIR /usr/local/src/nginx-1.12.2
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make -j6 && make install
ENV PATH /usr/local/nginx/sbin:$PATH
ADD nginx.conf /usr/local/nginx/conf/
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
EXPOSE 443
ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]


docker build -t nginx:lnmp .

docker run -d --name nginx -p 80:80 \
-v /opt/nginx/html:/usr/local/nginx/html \
--net mynetwork --ip 172.18.0.10 nginx:lnmp

三、部署mysql（容器IP 为 172.18.0.20）

mkdir /opt/mysqld
cd /opt/mysqld

上传 mysql-boost-5.7.20.tar.gz 到 /opt/mysqld 目录中

vim Dockerfile

FROM centos:7
MAINTAINER this is mysql image <lsq>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
RUN useradd -M -s /sbin/nologin  mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/
WORKDIR /usr/local/src/mysql-5.7.20/
RUN cmake \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make -j6 && make install
RUN chown -R mysql:mysql /usr/local/mysql/
RUN rm -rf /etc/my.cnf
ADD my.cnf /etc/
RUN chown mysql:mysql /etc/my.cnf
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
WORKDIR /usr/local/mysql/
RUN bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
EXPOSE 3306
ADD run.sh /usr/local/src
RUN chmod 755 /usr/local/src/run.sh
RUN sh /usr/local/src/run.sh

vim my.cnf
[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES


vim run.sh
#!/bin/bash
/usr/local/mysql/bin/mysqld
systemctl enable mysqld


docker build -t mysql:lnmp .

docker run --name=mysql -d --privileged -v /usr/local/mysql --net mynetwork --ip 172.18.0.20 mysql:lnmp /usr/sbin/init

四、部署php（容器IP 为 172.18.0.30）

mkdir /opt/php
cd /opt/php
 
上传 php-7.1.10.tar.bz2 到 /opt/php 目录中
 
vim Dockerfile

FROM centos:7
MAINTAINER this is php image <zhi>
RUN yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel \
gcc gcc-c++ make pcre-devel 
RUN 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 \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \

--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip && make -j8 && make install
ENV PATH /usr/local/php/bin:/usr/local/php/sbin:$PATH
ADD php.ini	/usr/local/php/lib/
ADD php-fpm.conf /usr/local/php/etc/
ADD www.conf /usr/local/php/etc/php-fpm.d/
EXPOSE 9000
ENTRYPOINT [ "/usr/local/php/sbin/php-fpm", "-F" ]

docker build -t php:lnmp .

docker run --name=php -d -p 9000:9000 --volumes-from mysql --volumes-from nginx --net mynetwork --ip 172.18.0.30 php:lnmp

docker exec -it mysql /bin/bash

mysql
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
flush privileges;
