最后修改时间2024-03-28

操作系统

Linux version 5.15.0-86-generic 
(buildd@lcy02-amd64-086) 
(gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, GNU ld (GNU Binutils for Ubuntu) 2.38) 
#96-Ubuntu SMP Wed Sep 20 08:23:49 UTC 2023

查找nginx1.24

sudo docker search nginx:1.24

拉nginx1.24

sudo docker pull nginx:1.24

查看docker镜像，检查是否已经拉取nginx镜像

sudo docker images

创建nginx相关文件夹

mkdir /home/ubuntu/nginx
mkdir /home/ubuntu/nginx/{logs,html,conf}
mkdir /home/ubuntu/nginx/conf/conf.d

创建nginx容器

sudo docker create \
--name testNginx \
-p 80:80 \
镜像名/镜像ID

如果需要挂载，样例如下

sudo docker create \
--name nginx_test \
-p 80:80 \
-v /home/ubuntu/nginx/nginx.conf:/etc/nginx/nginx.conf \
-v /home/ubuntu/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /home/ubuntu/nginx/logs:/var/log/nginx \
-v /home/ubuntu/nginx/html:/usr/share/nginx/html \
-v /etc/localtime:/etc/localtime:ro \
镜像名/镜像ID

后台运行创建的nginx容器

sudo docker start 容器id &

创建可后台运行的nginx容器

sudo docker run \
--name nginx_test \
-p 80:80 \
-d 镜像名/镜像ID

如果需要挂载，样例如下

sudo docker run \
-p 80:80 \
--name nginx_test \
-v /home/ubuntu/nginx/nginx.conf:/etc/nginx/nginx.conf \
-v /home/ubuntu/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /home/ubuntu/nginx/logs:/var/log/nginx \
-v /home/ubuntu/nginx/html:/usr/share/nginx/html \
-v /etc/localtime:/etc/localtime:ro \
-d 镜像名/镜像ID

端口映射
-p

--name
别名

挂载配置文件
-v /home/ubuntu/nginx/nginx.conf:/etc/nginx/nginx.conf \

挂载其他配置文件
-v /home/ubuntu/nginx/conf/conf.d:/etc/nginx/conf.d \

挂载日志
-v /home/ubuntu/nginx/logs:/var/log/nginx \

挂载html目录
-v /home/ubuntu/nginx/html:/usr/share/nginx/html \

容器时间与宿主机同步，ro只读
-v /etc/localtime:/etc/localtime:ro

后台启动
-d  镜像名/镜像ID

进入nginx容器

sudo docker exec -it 容器id /bin/bash

复制nginx配置文件

sudo docker cp 容器id:/etc/nginx/nginx.conf /home/ubuntu/nginx
sudo docker cp 容器id:/usr/share/nginx/html /home/ubuntu/nginx/html
sudo docker cp 容器id:/etc/nginx/conf.d /home/ubuntu/nginx/conf/conf.d

修改nginx配置文件用户组、用户权限

sudo chown -R ubuntu:ubuntu /home/ubuntu/nginx
sudo chmod -R 775 /home/ubuntu/nginx
