使用docker安装并运行nginx命令：
|
1
|
docker run --name=nginx -p 80:80 -d docker.io/nginx |
使用命令：
docker exec -it nginx /bin/bash 进入容器可查看到几个重要的文件
配置文件：nginx.conf 在 /etc/nginx/nginx.conf
日志文件： /var/log/nginx/access.log /var/log/nginx/error.log
使用cat命令打开nginx.conf

发现第32行，配置了一个子配置文件，进入conf.d发现有一个default.conf文件
打开default.conf文件：

在浏览器中输入:http://192.168.11.241
从default.conf中11行可以看出，index页面在/usr/share/nginx/html
现在，我们配置一下容器卷：
docker rm -f nginx 删除一下之前的容器
再次执行比较完整的命令：

docker run \ --restart=always \ --name nginx \ -d -p 80:80 \ -v /data/nginx/html:/usr/share/nginx/html \ -v /data/nginx/nginx.conf:/etc/nginx/nginx.conf \ -v /data/nginx/conf.d:/etc/nginx/conf.d \ -v /data/nginx/log:/var/log/nginx \ nginx |
这里有几个注意事项：
（1）第一个“-v”，是项目位置，把html代码放到挂载到的目录下即可；
（2）第二个“-v”，是挂载的主配置文件"nginx.conf"，注意"nginx.conf"文件内有一行"include /etc/nginx/conf.d/*.conf;"，
这个include指向了子配置文件的路径，此处注意include后所跟的路径一定不要出错。
（3）第三个“-v”，把docker内子配置文件的路径也挂载了出来，注意要与（2）中include指向路径一致
（4）重点强调一下，nginx.conf是挂载了一个文件（docker是不推荐这样用的），conf.d挂载的是一个目录
我们先启动一下，可以发现是有问题的，因为配置文件还没有。
[root@zuul-server data]# docker run --name nginx -d -p 80:80 -v /data/nginx/html:/usr/share/nginx/html -v /data/nginx/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/conf.d:/etc/nginx/conf.d -v /data/nginx/log:/var/log/nginx nginx

很明显，报错了，容器也没有启动成功，怎么解决了？
解决办法：
1 进入/data/nginx目录，
2 删除nginx.conf文件夹 rm -rf nginx.conf
3 新建nginx.conf文件 touch nginx.conf
4 然后把之前cat /etc/nginx/nginx.conf的内容放入到nginx.conf
5 同理,cd /data/nginx/conf.d ，touch default.conf,把之前 cat /etc/nginx/conf.d/default.conf中的内容放入到新建的default.conf中。
最后 docker restart nginx 搞定。
需要配置一个端口转发功能，业务需求是：以http://192.168.11/241/mp开头的请求需要重定向到http://192.168.11.241:20001/mp上，
刚开始把 proxy_pass 对应的路径写成了 http://127.0.0.1:20001/；导致报404错误，原因很简单，nginx运作在容器里面，肯定找不到http://127.0.0.1:20001/,浪费了我一点点时间，一时没转过弯来。
