[[email protected] ~]# docker start my_centos 启动容器
ctrl+p+q 安全退出
进入指定容器的2种方法
1.[[email protected] ~]# docker attach my_centos 不推荐
2.[[email protected] ~]# docker exec -it my_centos bash
[[email protected] ~]# docker exec -it my_centos ls /root/ —可以直接执行命
[[email protected] ~]# docker ps –a 查看所有容器
[[email protected] ~]# docker rm b126892480ef 删除容器

制作镜像 nginx+php
[[email protected] ~]# docker run -it --name my_nginx centos bash
[[email protected] yum.repos.d]# yum install nginx –y 装个nginx
[[email protected] /]# yum install php-fpm –y
[[email protected] ~]# docker cp supervisor-3.3.1-2.el7.noarch.rpm 151aa7950506:/root/
[[email protected] ~]# yum install supervisor-4.2.0-1.el8.noarch.rpm -管理工具
[[email protected] /]# vi /etc/supervisord.conf
[[email protected] /]# cd /etc/supervisord.d/
[[email protected] supervisord.d]# vi php_nginx.ini
[supervisord]
nodaemon=true
[program:nginx]
command=/usr/sbin/nginx -g “daemon off;”
[program:phpfpm]
command=/usr/sbin/php-fpm -F -c /etc/php.ini
autostart = true
startsecs = 3
autorestart = true
startretires =3
user = root
redirect_stderr = false
stdout_logfile_maxbytes = 50M
stdout_logfile_backups = 20
这里有个坑,要创建 不然无法执行
mkdir /run/supervisor/
mkidr /run/ php-fpm
[[email protected] run]# supervisord
包一个镜像
[[email protected] ~]# docker commit -m “nginx 1.1 php5.4” my_nginx nginx:v1
用制作的好镜像，做一个试试
[[email protected] ~]# docker run -it -p 80:80 --name nginx_v1 0878718cc64e supervisord
网页可以成功打开
制作个php文件
[[email protected] nginx]# pwd
/usr/share/nginx/html
vi phpinfo.php
