Docker 安装nginx

在docker启动nginx，并修改相关配置

1：查询nginx镜像 

docker search nginx

[root@iZbp1h2vcoigag0f1dn31mZ ~]# docker search nginx

OFFICIAL  表示官方的
其他的是通过第三方进行封装的

2：拉去镜像

docker pull nginx

[root@iZbp1h2vcoigag0f1dn31mZ ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
1ab2bdfe9778: Pull complete 
a17e64cfe253: Pull complete 
e1288088c7a8: Pull complete 
Digest: sha256:53ddb41e46de3d63376579acf46f9a41a8d7de33645db47a486de9769201fec9
Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest
[root@iZbp1h2vcoigag0f1dn31mZ ~]# 

 

3：启动nginx镜像容器

[root@iZbp1h2vcoigag0f1dn31mZ ~]# docker run --name test-nginx -p 80:80 -d nginx
e359a74aa8c386b3afe3c30472846c3a15f108b4368ea9fa30b974b14f6019cb

--name 容器名称

-p 端口绑定 其中：前面的是本地当前服务器端口 ，冒号后面的时候容器nginx访问端口 

-d 使用后台启动

直接使用浏览器访问当前服务器ip地址即可看到nginx服务。

 

4：进入访问内部容器 

docker exec -it test-nginx bash

[root@iZbp1h2vcoigag0f1dn31mZ /]# docker exec -it test-nginx bash
root@e359a74aa8c3:/# 

此时已经进入容器内部

nginx是docker内部已经设置好的，

nginx.conf 文件目录 /etc/nginx/nginx.conf

html文件目录 /usr/share/nginx/html

log文件目录 /var/log/nginx/access.log

 

参考nginx参数对nginx进行配置修改。具体根据自己需求调整

注：一般情况下非最佳实现方案。

 

5：磁盘挂载

-v ~/nginx/www:/usr/share/nginx/html 

docker run --name test-nginx3 -p 8080:80 -d -v ~/nginx/www:/usr/share/nginx/html  nginx 

将宿主机磁盘映射到docker虚拟机内部

-v path1:path2  其中path1是宿主机磁盘地址 path2是docker映射虚拟磁盘地址

可以定义多个 -v 映射多个文件夹

作用：可以使用一套环境启动多个服务。

 

6：重新载入 NGINX

docker kill -s HUP test-nginx

[root@iZbp1h2vcoigag0f1dn31mZ /]# docker kill -s HUP test-nginx
test-nginx

7：重启nginx容器

docker restart container-name

[root@iZbp1h2vcoigag0f1dn31mZ /]# docker restart test-nginx
test-nginx

 

 

 至此，docker使用nginx的简单操作已经完成。
