1、前置准备
1）CentOS 8.0 图形化安装
2）CentOS 8.0 基本配置
3）CentOS 8.0 创建LVM分区
4）CentOS 8.1 安装Docker
2、拉取Apache镜像
[root@Server ~]# docker image ls -a
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx 1.17.10 e791337790a6 3 days ago 127MB
elleflorio/svn-server latest 8cc13133f6ed 3 months ago 49.7MB
[root@Server ~]# docker image pull httpd:2.4.43

elleflorio/svn-server latest 8cc13133f6ed 3 months ago 49.7MB
3、运行临时容器
[root@Server ~]# docker image ls -a
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx 1.17.10 e791337790a6 4 days ago 127MB
httpd 2.4.43 bdc169d27d36 5 days ago 166MB
elleflorio/svn-server latest 8cc13133f6ed 3 months ago 49.7MB
[root@Server ~]# docker container ls -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7a5b653ef143 nginx:1.17.10 "nginx -g 'daemon of…" 2 hours ago Up About an hour 0.0.0.0:8000->80/tcp nginxsrv
dc4f9e71e3b3 elleflorio/svn-server:latest "/init" 3 hours ago Up 3 hours 443/tcp, 0.0.0.0:3690->3690/tcp, 0.0.0.0:8001->80/tcp svnsrv
[root@Server ~]# docker container run --name test -d httpd:2.4.43

4、复制容器文件
[root@Server ~]# mkdir -p /data/apache
[root@Server ~]# docker container cp test:/usr/local/apache2/htdocs /data/apache/
[root@Server ~]# docker container cp test:/usr/local/apache2/conf /data/apache/
[root@Server ~]# docker container cp test:/usr/local/apache2/logs /data/apache/
[root@Server ~]# mv /data/apache/conf /data/apache/conf.d
[root@Server ~]# mv /data/apache/htdocs /data/apache/www
[root@Server ~]# ls -l /data/apache
total 0
drwxr-xr-x 4 root root 84 Apr 16 16:54 conf.d
drwxr-xr-x 2 root root 23 Apr 21 19:02 logs
drwxr-xr-x 2 root root 6 Apr 21 19:04 www
5、删除临时容器
[root@Server ~]# docker container ls -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
55c5ded1e026 httpd:2.4.43 "httpd-foreground" 5 minutes ago Up 5 minutes 80/tcp test
7a5b653ef143 nginx:1.17.10 "nginx -g 'daemon of…" 2 hours ago Up 2 hours 0.0.0.0:8000->80/tcp nginxsrv
dc4f9e71e3b3 elleflorio/svn-server:latest "/init" 3 hours ago Up 3 hours 443/tcp, 0.0.0.0:3690->3690/tcp, 0.0.0.0:8001->80/tcp svnsrv
[root@Server ~]# docker container rm -f test
test
[root@Server ~]# docker container ls -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7a5b653ef143 nginx:1.17.10 "nginx -g 'daemon of…" 2 hours ago Up 2 hours 0.0.0.0:8000->80/tcp nginxsrv
dc4f9e71e3b3 elleflorio/svn-server:latest "/init" 3 hours ago Up 3 hours 443/tcp, 0.0.0.0:3690->3690/tcp, 0.0.0.0:8001->80/tcp svnsrv
6、创建正式容器
[root@Server ~]# docker container ls -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7a5b653ef143 nginx:1.17.10 "nginx -g 'daemon of…" 2 hours ago Up 2 hours 0.0.0.0:8000->80/tcp nginxsrv
dc4f9e71e3b3 elleflorio/svn-server:latest "/init" 3 hours ago Up 3 hours 443/tcp, 0.0.0.0:3690->3690/tcp, 0.0.0.0:8001->80/tcp svnsrv
[root@Server ~]# docker run -d -p 8002:80 \
> --name apachesrv \
> -v /data/apache/www:/usr/local/apache2/htdocs \
> -v /data/apache/conf.d:/usr/local/apache2/conf \
> -v /data/apache/logs:/usr/local/apache2/logs \
> --privileged=true --restart=always httpd:2.4.43

[root@Server ~]# docker container ls -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

7、验证Apache
