一、步骤

• 1.搜索nginx镜像
• 2.拉取nginx镜像
• 3.创建容器
• 4.测试nginx

二、示例

• 1.搜索nginx镜像

docker search nginx

• 2.拉取nginx镜像

docker pull nginx

• 3.创建容器，设置端口映射、目录映射

# 在root目录下创建nginx目录用于存储nginx数据信息
mkdir ~/nginx
cd ~/nginx
mkdir conf
cd conf
# 在~/nginx/conf/下创建nginx.conf文件，粘贴下面内容
vim nginx.conf

user  nginx;
worker_processes  1;error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;events {worker_connections  1024;
}http {include       /etc/nginx/mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile        on;#tcp_nopush     on;keepalive_timeout  65;#gzip  on;include /etc/nginx/conf.d/*.conf;}

• 4.创建容器

切回nginx目录执行

docker run -id --name=my_nginx \
-p 80:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx

参数说明

-p 80:80：将容器的80端口映射到宿主机的80端口
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：将主机当前目录下的/conf/nginx.conf挂载到容器的/etc/nginx/nginx.conf。配置的目录
-v $PWD/logs:/var/log/nginx：将主机当前目录下的logs目录挂载到容器的/var/log/nginx。日志的目录

• 5.外部访问

进入html目录，创建index.html
cd ~/nginx/html
vim index.html

hello docker nginx
