Docker installs Nginx reverse proxy server

How to run the front-end code on the server, first install Nginx, here I use Docker to install Nginx

---

1. Install the nginx docker image

1. Obtain the official image of nginx

docker pull nginx

2. View the mirror library

docker images

ps: We can see that our nginx mirror download is complete

If we mount the directory when we start it for the first time, because our host is an empty file, the configuration file in the Nginx container will be overwritten directly, causing the startup to fail.

3. The host creates the directory to be mounted

mkdir -p /home/nginx/conf
mkdir -p /home/nginx/logs
mkdir -p /home/nginx/html

-pThe role of the parameter is to allow the creation of multi-level directories

4. Start a container that does not mount

 docker run -d --name nginx-test  -p 8860:80 nginx

Order	describe
–name nginx	The name of the container to start
-d	Background process
-v	map directory
-p	Native port mapping maps port 8860 of the container to port 80 of the machine
	The last nginx in the statement is the name of the image used

check it out

Start successfully

5. Mount the configuration file to the host

Copy the nginx.conf file and conf.d folder in the container to the host

Check the name of your Nginx: here is nginx-test

# 将容器nginx.conf文件复制到宿主机
docker cp nginx-test:/etc/nginx/nginx.conf /home/nginx/conf/nginx.conf
# 将容器conf.d文件夹下内容复制到宿主机
docker cp nginx-test:/etc/nginx/conf.d /home/nginx/conf/conf.d
# 将容器中的html文件夹复制到宿主机
docker cp nginx-test:/usr/share/nginx/html /home/nginx/

到了，这一步都只是为了获取 Nginx的配置文件

Now that the acquisition is successful, the useless ones can be deleted

6. Stop/delete the container

docker ps -a #View all containers

docker ps View currently running containers

docker stop nginx-test stop nginx container | Container ID is also available, only the first 3 digits are required

docker images view container list

7. View the host file tree

7.1 Install the tree tree

yum install tree

7.2 View tree tree

tree

8. Restart a container with a mounted directory

 docker run \
 -p 8860:80 \
 --name learn-nginx \
 -v /home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
 -v /home/nginx/conf/conf.d:/etc/nginx/conf.d \
 -v /home/nginx/logs:/var/log/nginx \
 -v /home/nginx/html:/usr/share/nginx/html \
 -d nginx:latest

Check whether the startup is successful, then we will change the html content
and then check it to know
