从零开始Ubuntu24.04上Docker构建自动化部署（三）Docker安装Nginx

安装nginx

sudo docker pull nginx

启动nginx
宿主机创建目录
sudo mkdir -p /home/nginx/{conf,conf.d,html,logs}
先启动nginx
sudo docker run -d --name mynginx -p 80:80 nginx 
宿主机上拷贝docker上nginx服务上文件到本地目录
sudo docker cp mynginx:/etc/nginx/nginx.conf /home/nginx/conf/
sudo docker cp mynginx:/etc/nginx/conf.d /home/nginx/
sudo docker cp mynginx:/usr/share/nginx/html /home/nginx/
sudo docker cp mynginx:/var/log/nginx /home/nginx/logs

停止docker 上nignx
sudo docker stop mynginx
删除docker上nginx容器
sudo docker rm mynginx

重启启动nginx容器
sudo docker run -d --name mynginx -p 80:80  --restart=always  --volume /home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf --volume /home/nginx/conf.d:/etc/nginx/conf.d --volume /home/nginx/html:/usr/share/nginx/html --volume /home/nginx/logs:/var/log/nginx --privileged=true nginx 

还有种方式，如果不创建目录，将原始文件拷贝过来，也可在启动后，手动创建文件

创建nginx.conf文件

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; }

创建default.conf文件

server {listen       80;server_name  localhost;#charset koi8-r;#access_log  /var/log/nginx/host.access.log  main;location / {root   /home/nginx/html;index  index.html index.htm;}}

修改完成后，重启nginx

当访问浏览器时，会找不到页面存在，不过不影响部署成功

如果实在想要，那就自己写个html页面放到/home/nginx/html下即可
