目录
一、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。
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/
二、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 |
三、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 512MB 的内存和 1G 的 Swap
限制 Mysql 容器写 /dev/sda 的速率为 10 MB/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
四、获取 Linux 系统基础镜像
获取Linux基础镜像
docker pull centos:7
docker images
五、Nginx
1. 建立工作目录
mkdir /opt/nginx
cd /opt/nginx
# 上传 nginx 安装包 nginx-1.12.0.tar.gz,wordpress 服务包 wordpress-4.9.4-zh_CN.tar.gz
rz -E
2. 编写 Dockerfile 脚本
vim Dockerfile
FROM centos:7 # 使用CentOS 7作为基础镜像
MAINTAINER this is nginx image <lnmp> # 维护者信息
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make # 安装编译Nginx所需的依赖包
RUN useradd -M -s /sbin/nologin nginx # 创建一个名为nginx的系统用户,用于运行Nginx
ADD nginx-1.12.0.tar.gz /usr/local/src/ # 将本地的nginx源码包复制到容器内的/usr/local/src/目录下
WORKDIR /usr/local/src/nginx-1.12.0 # 设置工作目录为nginx源码路径
RUN ./configure \ # 配置Nginx编译选项
--prefix=/usr/local/nginx \ # 指定安装路径
--user=nginx \ # 指定运行Nginx的用户
--group=nginx \ # 指定运行Nginx的用户组
--with-http_stub_status_module # 启用HTTP stub status模块
RUN make -j 4 && make install # 编译并安装Nginx
ENV PATH /usr/local/nginx/sbin:$PATH # 将Nginx可执行文件添加到环境变量中
ADD nginx.conf /usr/local/nginx/conf/ # 将本地的nginx配置文件复制到容器内的/usr/local/nginx/conf/目录下
ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html # 将本地的wordpress应用复制到容器内的/usr/local/nginx/html/目录下
RUN chmod 777 -R /usr/local/nginx/html/ # 设置/usr/local/nginx/html/目录的权限为777,使其对所有用户可写
EXPOSE 80 # 暴露容器的80端口,供外部访问Nginx
VOLUME [ "/usr/local/nginx/html/" ] # 创建一个卷,挂载到容器的/usr/local/nginx/html/目录上
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ] # 容器启动后执行的命令,以非守护进程方式运行Nginx
3. 编辑 nginx 的主配置文件
vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
charset utf-8;
location / {
root html;
index index.html index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
root html;
fastcgi_pass 172.20.0.30:9000;
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" mynetwork
6. 启动镜像容器
docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1.5g --net mynetwork --ip 172.20.0.10 nginx:lnmp
docker ps
docker inspect nginx
7. 验证 nginx
curl http://192.168.23.40:80
