Docker安装Nginx1.19.4

1.下载Nginx镜像

docker pull nginx:1.19.4

通过 docker images 命令检查一下镜像是否下载成功：

# docker images

2.运行Nginx容器

docker run -d -p 80:80 --name nginx nginx:1.19.4

参数说明：

• -p 80:80: 将容器的 80 端口映射到宿主机的 80 端口上；
• -d: 以后台方式运行镜像；
• --name: 指定容器的名称为 nginx;

3.进入nginx容器

首先查看nginx容器。

[root@localhost ~]# docker ps -a

进入nginx容器。

[root@localhost ~]# docker container exec -it nginx  /bin/bash

#也可以简写如下：

[root@localhost ~]# docker exec -it nginx bash

4.重新部署生成环境的nginx容器

以上部署的nginx容器不具备生产环境，因为容器重启会丢失内部数据，因此要将需要持久化的文件挂载到宿主机中，以防数据丢失。

首先我们在宿主主机的/usr/local下，创建nginx容器要挂载在宿主主机的目录。/usr/local/nginx

如下图所示：

注意：在conf目录下一定要新建nginx.conf文件。(注意：一定是文件不能是目录，重要的事情说三遍！)

重新部署容器：

docker run -d -p 80:80 \
--name nginx-prod \
-v /usr/local/nginx/html:/usr/share/nginx/html \
-v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /usr/local/nginx/logs:/var/log/nginx  nginx:1.19.4

编辑/usr/local/nginx/nginx.conf如下：

  worker_connections  1024;  ## Default: 1024

    include       mime.types;
