1.1 Download all installation packages:
2.1. Create a working directory
2.3 Prepare nginx.conf configuration file
3.1 Create a working directory
4.1 Create a working directory
4.3 Prepare php.ini, php-fpm.conf, www.conf configuration files
5.1.1 Enter the mysql container
1. Project environment
In the actual production environment, the company needs to use Docker technology to create an LNMP service and run the Wordpress website platform on a host. Then perform related performance tuning and management work on this service.
1.1 Download all installation packages:
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
or
wget -r -np http://101.34.22.188/lnmp_wordpress/
1.3 Server environment
| container | operating system | IP address | main software |
| nginx | CentOS 7 | 192.168.237.21 | Docker-Nginx |
| mysql | CentOS 7 | 192.168.237.22 | Docker-Mysql |
| PHP | CentOS 7 | 192.168.237.23 | Docker-php |
1.4 Task Requirements
- Use Docker to build LNMP environment and run Wordpress website platform
- Limit the Nginx container to use up to 500MB of memory and 1G of Swap
- Limit the writing rate of Mysql container to /dev/sda to 10 MB/s
- Take a snapshot of all containers, then package the Docker image into a tar package and back it up locally
二、Ngin
2.1. Create a working directory
[root@docker ~]# mkdir /opt/nginx
[root@docker ~]# cd /opt/nginx
#上传 nginx 安装包 nginx-1.12.0.tar.gz
#上传 wordpress 服务包 wordpress-4.9.4-zh_CN.tar.gz
2.2 Write Dockerfile script
[root@docker nginx]# 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

RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME [ "/usr/local/nginx/html/" ]
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ]2.3 Prepare nginx.conf configuration file
[root@docker nginx]# ls
