一、检查本地系统版本

[root@node ~]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

二、检查docker状态

[root@node ~]# systemctl status docker

四、创建nginx容器

1.创建数据目录

[root@node ~]# mkdir /data/nginx
[root@node ~]# cd /data/nginx/
[root@node nginx]# ls
[root@node nginx]# 

2.运行nginx容器

[root@node nginx]# docker run -d --name my_web01 --restart always -p 8744:80 -v /data/nginx/:/usr/share/nginx/html/ nginx
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx

349f6f002567d13ec9a4a871b730d85173c7c9a8038067ae4d9369d091e96ba4

3.查看nginx容器状态

[root@node nginx]# docker ps
CONTAINER ID   IMAGE                                                   COMMAND                  CREATED         STATUS                  PORTS                                             NAMES
349f6f002567   nginx                                                   "/docker-entrypoint.…"   2 minutes ago   Up 2 minutes            0.0.0.0:8744->80/tcp, :::8744->80/tcp             my_web01

4.查看容器日志

[root@node nginx]# docker logs my_web01
/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/

五、访问nginx

1.编辑index.html

[root@node nginx]# echo "nginx aa-bb" > index.html
[root@node nginx]# pwd
/data/nginx

2.访问nginx
