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 days ago 109MB
3、在Docker中启用Nginx
[root@localhost ~]# docker run -p : --name myNginx -d nginx
ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5
4、查看启动的nginx进程
[root@localhost ~]# ps -ef|grep nginx
root : ? :: nginx: master process nginx -g daemon off;
: ? :: nginx: worker process
root : pts/ :: grep --color=auto nginx
5、访问nginx
[root@localhost ~]# curl http://localhost:80/

6、监测Nginx引用状态

7、停止Nginx应用
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ad7cc45c81ff nginx "nginx -g 'daemon of…" seconds ago Up seconds 0.0.0.0:->/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 : pts/ :: grep --color=auto nginx
[root@localhost ~]# curl http://localhost:80/
curl: () Failed connect to localhost:; 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: () Failed connect to localhost:; Connection refused
[root@localhost ~]# docker run -p : --name myNginx -d nginx
598c5f3d52e0511480eebb031c2cdee05b155054edd014ca22ca1bef49d62867
[root@localhost ~]# curl http://localhost:8899/
