Docker 部署 Nginx

搜索镜像

docker search nginx

拉取镜像

版本号可以去官网查看：https://hub.docker.com/_/nginx

docker pull nginx:1.20.2

创建目录

mkdir ~/nginx
cd ~/nginx
mkdir conf
cd conf
vim nginx.conf

nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
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;
}

端口配置

server { 
    listen 80;
    location / {
        root   html;
        index  index.html index.htm;
    }
}

创建容器

• -p 80:80：冒号前的80是宿主机端口，冒号后的80是容器端口。

docker run -d \
--name=nginx \
-p 80:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/conf/conf.d:/etc/nginx/conf.d \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx:1.20.2

不指定配置（快速测试用）

docker run -d \
--name=nginx \
-p 80:80 \
-v $PWD/conf.d:/etc/nginx/conf.d \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx:1.20.2

可能出现的错误

WARNING: IPv4 forwarding is disabled. Networking will not work.

开启ipv4转发

echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
systemctl restart network

进入容器

docker exec -it c_nginx bash

重启

docker exec -it nginx nginx -s reload
