第二十二节 虚拟机环境准备-nginx

亮子 2024-03-21 06:27:09 8070 0 0 0

1、下载镜像

docker pull nginx:1.17.8

2、在宿主机创建3个目录

# 1、创建www目录
mkdir -p /server/nginx/html
# 2、创建日志目录
mkdir -p /server/nginx/logs
# 3、创建配置目录
mkdir -p /server/nginx/conf

3、创建容器

docker run -d -p 80:80 -p 443:443 --name nginx -v /server/nginx/html:/usr/share/nginx/html -v  /server/nginx/logs:/var/log/nginx --privileged=true nginx:1.17.8

4、测试容器

由于我们把容器内的 /usr/share/nginx/html 目录映射到了宿主机，所以我们需要在宿主机的 /server/nginx/html目录下，创建一个index.html文件，这样在测试访问的时候，才不至于找不到默认页面而出错。
