docker安装nginx

1.查找镜像

docker search命令查找，也可以去docker hub（https://hub.docker.com）上搜索！！！

[root@localhost ~]# docker search nginx

2.下载镜像

[root@localhost ~]# docker pull nginx

3.运行测试

//-p表示暴漏端口 命令：-p:宿主机端口:容器内部端口
//将nginx01的80端口映射到宿主机的3344端口
[root@localhost ~]# docker run -d --name nginx01 -p 3344:80 nginx
0088cd8839470a433f559547fbd7037fc43802b16e0f4da3aa3df1e61a5a8889
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES
0088cd883947        nginx               "/docker-entrypoint.…"   15 seconds ago      Up 13 seconds       0.0.0.0:3344->80/tcp   nginx01
//本地访问刚才映射的3344端口测试
[root@localhost ~]# curl localhost:3344

4.进入容器

[root@localhost ~]# docker exec -it nginx01 /bin/bash
root@0088cd883947:/# whereis nginx
nginx: /usr/sbin/nginx /usr/lib/nginx /etc/nginx /usr/share/nginx
root@0088cd883947:/# cd /etc/nginx
root@0088cd883947:/etc/nginx# ls
conf.d    fastcgi_params    mime.types  modules  nginx.conf  scgi_params  uwsgi_params

5.停止容器服务

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES
0088cd883947        nginx               "/docker-entrypoint.…"   30 minutes ago      Up 30 minutes       0.0.0.0:3344->80/tcp   nginx01
//使用stop命令停止
[root@localhost ~]# docker stop 0088cd883947
0088cd883947

停止服务后浏览器再访问会报错，因为刚才已经用stop命令将服务停止了。
