一、前期准备

1.1 搭建项目环境

公司在实际的生产环境中需要使用Docker技术在一台主机上创建LNMP服务并运行Wordpress网站平台。然后对此服务进行相关的性能调优和管理工作。

1.2 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/

1.3 服务器环境

容器	操作系统	IP地址	主要软件
nginx	CentOS 7	172.20.0.10	Docker-Nginx
mysql	CentOS 7	172.20.0.20	Docker-Mysql
php	CentOS 7	172.20.0.30	Docker-php

1.4 任务需求

使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
限制 Nginx 容器最多使用500MB的内存和1G的 Swap
限制 Mysql 容器写/dev/sda的速率为10MB/s
将所有容器进行快照，然后将 Docker 镜像打包成tar包备份到本地

二、实验部署

2.1 nginx

2.1.1 前期准备

关闭防火墙

systemctl stop firewalld

setenforce 0

2.1.2 创建并进入nginx文件夹，下载压缩包

mkdir /opt/nginx/

cd /opt/nginx/

2.1.3 编辑Dockerfile

vim Dockerfile

FROM centos:7
MAINTAINER this is nginx image <cht>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN 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 -j4 && 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
EXPOSE 443
ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]

2.1.4 编辑nginx

vim nginx.conf

2.1.5 过滤nginx配置文件内容

egrep -v "^(.)*#(.)*$" nginx.conf | grep -v "^$"

2.1.6 创建html文件夹，压缩文件到创建的文件夹内

mkdir /opt/nginx/html/

tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html/

2.1.7 生成镜像

docker build -t nginx:lnmp .

2.1.8 创建容器

docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker" mynetwork

2.1.9 在后台启动镜像容器:

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

docker ps

2.2 mysqld

2.2.1 前期准备

systemctl stop firewalld

setenforce 0

2.2.2 创建并进入mysqld文件夹

mkdir /opt/mysqld

cd /opt/mysqld

2.2.3 编辑Docker

vim Dockerfile

FROM centos:7
MAINTAINER this is mysql image <cht>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/

-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make -j 2 && make install
ADD my.cnf /etc/
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
RUN useradd -M -s /sbin/nologin mysql
RUN chown mysql:mysql /etc/my.cnf
RUN chown -R mysql:mysql /usr/local/mysql/
RUN /usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
EXPOSE 3306
CMD ["/usr/local/mysql/bin/mysqld"]

2.2.4 编辑mysql核心文件

vim my.cnf

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

[mysql]
port = 3306
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
