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/
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 |
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 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
