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/ <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html>
6、监测Nginx引用状态
[root@localhost ~]# docker inspect ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5 [ { "Id": "ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5", "Created":

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/ <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html>
