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 REPOSITORYTAGIMAGE IDCREATEDSIZE nginxlatest881bd08c0b087 days ago109MB

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 root13223132080 05:50 ?00:00:00 nginx: master process nginx -g daemon off; 10113253132230 05:50 ?00:00:00 nginx: worker process root13262123500 05:50 pts/100:00:00 grep --color=auto nginx

5、访问nginx

[root@localhost ~]# curl http://localhost:80/ Welcome to nginx! - 锐客网body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } Welcome to nginx!If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

Commercial support is available at "http://nginx.com/">nginx.com.
Thank you for using nginx.

6、监测Nginx引用状态

[root@localhost ~]# docker inspect ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5 [ { "Id": "ad7cc45c81ffadbd44254c1c043e048c677a4ebcd4ca618efcd098729cec2fa5", "Created": "2019-03-12T09:58:06.595522099Z", "Path": "nginx", "Args": [ "-g", "daemon off;

7、停止Nginx应用

[root@localhost ~]# docker ps CONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMES ad7cc45c81ffnginx"nginx -g 'daemon of…"23 seconds agoUp 23 seconds0.0.0.0:80->80/tcpmyNginx [root@localhost ~]# docker stop ad7cc45c81ff ad7cc45c81ff

8、查看Nginx进程，访问80端口

[root@localhost ~]# ps -ef|grep nginx root13319123500 05:50 pts/100:00:00 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/ Welcome to nginx! - 锐客网body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } Welcome to nginx!If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
