使用Docker容器部署LNMP服务

实验前准备

宿主机：192.168.188.17
所有安装包下载：
wget http://101.34.22.188/lnmp_wordpress/mysql-boost-5.7.20.tar.gz
wget http://101.34.22.188/lnmp_wordpress/nginx-1.12.0.tar.gz
wget http://101.34.22.188/lnmp_wordpress/php-7.1.10.tar.bz2
wget http://101.34.22.188/lnmp_wordpress/wordpress-4.9.4-zh_CN.tar.gz
或者
wget -r -np http://101.34.22.188/lnmp_wordpress/
环境准备
容器操作系统 IP地址 主要软件
nginx Centos7 172.20.0.10 Docker-Nginx
mysql Centos7 172.20.0.20 Docker-Mysql
php Centos7 172.20.0.30 Docker-php

关闭防火墙
systemctl stop firewalld
setenforce 0
创建自定义网段
docker network create --subnet=172.20.0.0/16 --opt “com.docker.network.bridge.name”=“docker1” mynetwork

部署Nginx

环境准备

mkdir /opt/nginx
上传nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中
cd /opt/nginx
mkdir /opt/nginx/html
tar -zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html
编写Dockerfile脚本
vim Dockerfile

FROM centos:7
MAINTAINER this is nginx image <lnmp>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.0.tar.gz /usr/local/src/
WORKDIR /usr/local/src/nginx-1.12.0
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module;make -j 4 && make install
ENV PATH /usr/local/nginx/sbin:$PATH
ADD nginx.conf /usr/local/nginx/conf/
ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME [ "/usr/local/nginx/html/" ]
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ]

准备nginx.conf配置文件

复制一份nginx.conf配置文件到/opt/nginx/目录下
主要是增加一个动态页面的location块，这里的IP要写PHP服务的容器ip

生成并启动镜像

docker build -t nginx:lnmp .

docker images

启动镜像容器
docker run --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.20.0.10 -d nginx:lnmp
docker ps

验证nginx

curl 192.168.188.17:80

部署Mysql

准备工作目录

mkdir /opt/mysql
cd /opt/mysql
把mysql-boost-5.7.20.tar.gz复制到/opt/mysql

编写Dockerfile脚本

vim Dockerfile

FROM centos:7
MAINTAINER this is mysql images <wl>
RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin mysql

ADD my.cnf /etc/my.cnf
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 \

--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data;cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/;systemctl enable mysqld
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
VOLUME [ "/usr/local/mysql" ]
CMD [ "/usr/sbin/init" ]

准备my.cnf文件

在/opt/mysql下准备一个
vim my.cnf

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysql]
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash

[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
bind-address = 0.0.0.0

max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M

生成并启动镜像

docker build -t mysql:lnmp .

启动镜像容器

docker run --name=mysql --privileged --device-write-bps /dev/sda:10M -v /usr/local/mysql --net mynetwork --ip 172.20.0.20 -d mysql:lnmp

验证mysql

docker exec -it mysql bash
systemctl status mysqld

部署php

建立工作目录

mkdir /opt/php
cd /opt/php
复制php-7.1.10.tar.bz2到/opt/php

编写Dockerfile脚本

vim Dockerfile

FROM centos:7
MAINTAINER this is php image <wl>

libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \

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
CMD /usr/local/php/sbin/php-fpm -F

准备配置文件

php.ini需要进行如下修改
取消注释，修改时区

修改套接字

php-fpm.conf需要进行如下修改
取消注释

www.conf需要进行如下修改
修改用户和组

修改监听ip和端口

运行访问的ip

生成并启动镜像

docker build -t php:lnmp .

启动镜像容器
docker run --name php --net mynetwork --ip 172.20.0.30 -p 9000:9000 --volumes-from nginx --volumes-from mysql -itd php:lnmp

验证php

docker exec -it php bash
ps -aux

启动wordpress

mysql授权

进入mysql容器
docker exec -it mysql bash
mysql -u root -p
初始密码为空，直接回车就行
create database wordpress;
grant all privileges on wordpress.* to ‘wordpress’@‘%’ identified by ‘123456’;
grant all privileges on . to ‘root’@‘%’ identified by ‘123456’;
flush privileges;
