docker安装nginx

目录

1、官网搜索镜像

 2、拉取镜像并查看

3、启动

 4、测试

1、官网搜索镜像

官网地址：Docker Hub

搜索nginx，会出来很多版本的镜像，一般拉取官方的或者star数多的，详细信息可以参考官网

 2、拉取镜像并查看

[root@iZbp1dlz0y8paqewduhmx6Z ~]# docker pull nginx

REPOSITORY    TAG       IMAGE ID       CREATED        SIZE
nginx         latest    605c77e624dd   3 months ago   141MB

[root@iZbp1dlz0y8paqewduhmx6Z ~]# 

3、启动

[root@iZbp1dlz0y8paqewduhmx6Z ~]# docker run -d -p80:80  --name nginx01 nginx
dbba3d32465ac57fe022f1b6541612cdc477d108d79a50bd148f9dbdb51ef54f
[root@iZbp1dlz0y8paqewduhmx6Z ~]# docker ps
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                NAMES
dbba3d32465a   nginx     "/docker-entrypoint.…"   5 seconds ago   Up 5 seconds   0.0.0.0:80->80/tcp   nginx01
[root@iZbp1dlz0y8paqewduhmx6Z ~]# 

说明：docker run -d -p 80:80  --name nginx01 nginx

-d:后台启动

--name  给镜像起个名字，如果不起就是默认的nginx

-p 80:80   第一个80是虚拟机的端口，第二个80是nginx的端口，这一步就是将容器内部的端口映射到外部的端口

方便直接在外面用80端口访问

                                          

 4、测试

记得关闭防火墙

1、虚拟机中测试：  curl  localhoat:80  发现是成功的

[root@iZbp1dlz0y8paqewduhmx6Z ~]# curl localhost:80







Welcome to nginx!
If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.

For online documentation and support please refer to
nginx.org.

Commercial support is available at
nginx.com.

Thank you for using nginx.


[root@iZbp1dlz0y8paqewduhmx6Z ~]# 

2、外网测试

 3、进入nginx容器内部查看配置文件

        命令：docker exec -it nginx01 /bin/bash

root@iZbp1dlz0y8paqewduhmx6Z ~]# docker exec -it nginx01 /bin/bash
root@dbba3d32465a:/etc# ls
adduser.conf		cron.daily	fonts	  host.conf  ld.so.cache    mke2fs.conf    pam.conf   rc2.d	   security  subuid
alternatives		debconf.conf	fstab	  hostname   ld.so.conf     motd	   pam.d      rc3.d	   selinux   systemd
apt			debian_version	gai.conf  hosts      ld.so.conf.d   mtab	   passwd     rc4.d	   shadow    terminfo
bash.bashrc		default		group	  init.d     libaudit.conf  netconfig	   passwd-    rc5.d	   shadow-   timezone
bindresvport.blacklist	deluser.conf	group-	  inputrc    localtime	    nginx	   profile    rc6.d	   shells    ucf.conf
ca-certificates		dpkg		gshadow   issue      login.defs     nsswitch.conf  profile.d  rcS.d	   skel      update-motd.d

root@dbba3d32465a:/etc# ll

这一步相当于进入了宿主机里面的nginx容器中，对linux进行配置。但是这样非常麻烦，每次部署应用后修改文件都得进入子容器中，有没有办法，能够在宿主机目录直接修改了，答案是有的，那就是数据卷技术。下篇接着讲
