Docker部署Nginx应用(2)

Docker部署Nginx应用(2)

1、拉取Nginx镜像

[root@localhost ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
f7e2b70d04ae: Pull complete 
08dd01e3f3ac: Pull complete 
d9ef3a1eb792: Pull complete 
Digest: sha256:98efe605f61725fd817ea69521b0eeb32bef007af0e3d0aeb6258c6e6fe7fc1a
Status: Downloaded newer image for nginx:latest

2、查看拉取到的镜像

[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              881bd08c0b08        7 days ago          109MB

3、在Docker中启用Nginx

[root@localhost ~]# docker run -p 80:80 --name myNginx -d nginx
ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5

4、查看启动的nginx进程

[root@localhost ~]# ps -ef|grep nginx
root      13223  13208  0 05:50 ?        00:00:00 nginx: master process nginx -g daemon off;
101       13253  13223  0 05:50 ?        00:00:00 nginx: worker process
root      13262  12350  0 05:50 pts/1    00:00:00 grep --color=auto nginx

5、访问nginx

[root@localhost ~]# curl http://localhost:80/

Thank you for using nginx.

6、监测Nginx引用状态

[root@localhost ~]# docker inspect ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5

                }
            }

7、停止Nginx应用

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
ad7cc45c81ff        nginx               "nginx -g 'daemon of…"   23 seconds ago      Up 23 seconds       0.0.0.0:80->80/tcp   myNginx
[root@localhost ~]# docker stop ad7cc45c81ff
ad7cc45c81ff

8、查看Nginx进程,访问80端口

[root@localhost ~]# ps -ef|grep nginx
root      13319  12350  0 05:50 pts/1    00:00:00 grep --color=auto nginx
[root@localhost ~]# curl http://localhost:80/
curl: (7) Failed connect to localhost:80; Connection refused

9、删除Nginx应用Container(一般需要先停止后才能删除,强制删除使用 docker rm -f xxx)

[root@localhost ~]# docker stop ad7cc45c81ff
ad7cc45c81ff
[root@localhost ~]# docker rm ad7cc45c81ff
ad7cc45c81ff

 10、Docker的Nginx应用映射到主机8899端口

[root@localhost ~]# curl http://localhost:8899/
curl: (7) Failed connect to localhost:8899; Connection refused
[root@localhost ~]# docker run -p 8899:80 --name myNginx -d nginx
598c5f3d52e0511480eebb031c2cdee05b155054edd014ca22ca1bef49d62867
[root@localhost ~]# curl http://localhost:8899/
