Simple use of Nginx

Install Nginx

1. Pull the Nginx image

docker pull nginx:latest
Copy the code

2. Run a temporary container for copying internal config files

docker run --rm -d --name nginx:latest nginx-temp
Copy the code

3. Generate nginx configurations, static resource directories, and log-related directory mappings on the host

mkdir -p ./nginx/{conf,html,logs}
Copy the code

4. Put the container insidenginx.conf 和 default.confTo the host machine/confIn the directory

docker cp nginx-temp:/etc/nginx/nginx.conf ./
docker cp nginx-temp:/etc/nginx/conf.d/default.conf ./conf/
Copy the code

5. Deleting temporary containers

Docker stop nginx-temp # Docker stop nginx-temp # docker stop nginx-temp #Copy the code

6. Run the new nginx container

docker run -d --name nginx -p 80:80 -v /root/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /root/nginx/conf:/etc/nginx/conf.d -v /root/nginx/html:/usr/share/nginx/html -v /root/nginx/logs:/var/log/nginx - ring = true nginx: latest # - v: according to the Shared between host and container directory # - ring = true inside the container to mount the directory has read and write privileges, etcCopy the code

7. in/root/nginx/htmlCreate a directoryindex.htmlFile and then access the host IP to access the page.

Basic configuration of Nginx

1. Check the nginx. Conf

cat nginx/nginx.conf
Copy the code

# Initial configuration
main                                # global configuration
events {                            # Nginx working mode configuration
}
http {                                # set the HTTP
    .

    server {                        # server host configuration
        .
        location {                    # Route configuration
            .
        }

        location path {
            .
        }

        location otherpath {
            .}}server {
        .

        location {
            .}}upstream name {                    Load balancing configuration
        .}}Copy the code

2. Configure access to static resources

server{ listen 80; server_name localhost; # public IP address or domain name index index.html index.htm; location / { root /usr/share/nginx/html index index.html index.htm } }Copy the code

3. Domain name forward

server{ listen 80; server_name test.site.com; index index.html index.htm; location / { proxy_pass http://www.baidu.com; proxy_set_header Host $proxy_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }}Copy the code

4. Port forwarding

server{ listen 80; server_name test.site.com; index index.html index.htm; Location /express/ {proxy_pass http://127.0.0.1:8080; proxy_set_header Host $proxy_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }}Copy the code

Proxy_pass specifies whether to add/to the address after proxy_pass

• add/Represents the root absolute path:Test.site.com/express/ind…Forwarded to thehttp://127.0.0.1:8080/index.html
• Do not add/: represents the relative path:Test.site.com/express/ind…Forwarded to thehttp://127.0.0.1:8080/express/index.html

5. Load Balancing Configuration

Upstream backend {server 127.0.0.1:81; Server 127.0.0.1:82; } # in server: location / {proxy_pass http://backend; }Copy the code
