Docker创建 LNMP 服务+Wordpress 网站平台

一.环境及准备工作

1.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。

容器系统 IP地址软件
nginx centos 7.5 172.18.0.10 wordpress-6.0.2-zh_CN.tar.gz、nginx-1.12.2.tar.gz
mysql centos 7.5 172.18.0.20 mysql-boost-5.7.25.tar.g
php centos 7.5 172.18.0.30 php-7.1.24.tar.gz

2.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

3.任务需求

（1）使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
（2）限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap
（3）限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s
（4）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.Linux 系统基础镜像

规划三台操作系统的内存及大小4+4G

提前关闭防火墙

#关闭防火墙
systemctl stop firewalld.service
setenforce 0

提前安装好Docker容器

下载完之后提前下载centos7的镜像

docker pull centos:7

三.docker构建Nginx

1.建立工作目录上传安装包

mkdir /opt/nginx
cd /opt/nginx
#上传 nginx 安装包 nginx-1.12.2.tar.gz和wordpress 服务包wordpress-6.0.2-zh_CN.tar.gzls
nginx-1.12.2.tar.gz  wordpress-6.0.2-zh_CN.tar.gz

2.编写 Dockerfile 脚本

vim Dockerfile
FROM centos:7
#指定基础镜像MAINTAINER ydq
#指定维护者信息RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
#安装依赖包，安装环境RUN useradd -M -s /sbin/nologin nginx
#创建nginx用户ADD nginx-1.12.2.tar.gz /opt
#将本地安装包上传到指定目录(自动解压)WORKDIR /opt/nginx-1.12.2
#进入到/opt/nginx-1.12.2目录中RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
#开始编译安装,加上&&符号，只有前面执行完成，后面才会执行ENV PATH=/usr/local/nginx/sbin:$PATH
#将nginx执行命令放入到环境变量中ADD nginx.conf /usr/local/nginx/conf/nginx.conf
#在宿主机写好配置文件，然就将配置文件复制到容器中ADD wordpress-6.0.2-zh_CN.tar.gz /usr/local/nginx/html
#上传论坛的包RUN chmod 777 -R /usr/local/nginx/html
#给html文件所有权限EXPOSE 80
#开放80端口VOLUME ["/usr/local/nginx/html/"]
#挂载目录(相当于将/usr/local/nginx/html目录共享，会在宿主机上自动生成共享目录，主要目的是为了让容器之间共享这个文件)CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]
#执行启动nginx命令,并且关闭nginx的后台启动，因为需要它占用前台，让docker不关闭。

3.准备 nginx.conf 配置文件

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$ {         #当访问以.php结尾的URL时，会连接到172.18.0.30的ip地址上root           html;fastcgi_pass   172.18.0.30:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;include        fastcgi_params;}}
}

4.生成镜像

docker build -t nginx:lnmp .
docker images

5.创建自定义网络

docker network create --subnet=172.20.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetworkdocker network ls
ifconfig docker1

在这里插入图片描述

6.启动镜像容器

docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.18.0.10 nginx:lnmp
#启动容器
----------------------------
-m 500: #表示该容器内存最大为500MB
--memory-swap: #表示内存+swap总共1G，那swap也是500MB
————————————————
docker ps -a

在这里插入图片描述

docker inspect nginx

7.验证 nginx

#进入容器验证
curl http://192.168.27.22:80<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>body {width: 35em;margin: 0 auto;font-family: Tahoma, Verdana, Arial, sans-serif;}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p><p>For online documentation and support please refer to
<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p><p><em>Thank you for using nginx.</em></p>
</body>
</html>

四.docker构建Mysql

1. 建立工作目录

mkdir /opt/mysql
cd /opt/mysql/
#传入mysql安装包mysql-boost-5.7.25.tar.gz

2. 编写 Dockerfile

vim Dockerfile

#基础镜像MAINTAINER ydq
#维护人信息RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make
#安装环境RUN useradd -M -s /sbin/nologin mysql
#创建mysql用户ADD mysql-boost-5.7.25.tar.gz /opt
#将mysql安装包上传(自带boost)WORKDIR /opt/mysql-5.7.25
#切换到mysql解压后的目录RUN cmake \

#设置权限ENV PATH /usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
#设置环境变量WORKDIR /usr/local/mysql/bin
#切换目录RUN ./mysqld \
--initialize-insecure \

--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
#初始化mysqlRUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
#复制mysql服务程序到启动文件中VOLUME ["/usr/local/mysql"]
#设置共享目录CMD ["/usr/sbin/init"]
#启动容器之后，可以使用systemctl工具(并且占用前台，保持容器不断)

3. 准备 my.cnf 文件

vim /opt/mysql/my.cnf[client]
port = 3306
socket=/usr/local/mysql/mysql.sock[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
