docker 安装 fastdfs

1、安装docker(已安装的跳过这一步)

2、安装FastDFS

## 这里我使用的腾讯云个人镜像
docker pull ccr.ccs.tencentyun.com/satan/fastdfs:6.06

## 创建挂载映射文件夹
mkdir /data/fdfs/tracker /data/fdfs/storage

## 安装tracker
docker run -dti --network=host --name tracker -v /data/fdfs/tracker:/var/fdfs ccr.ccs.tencentyun.com/satan/fastdfs:6.06 tracker

## 安装storage
docker run -dti --network=host --name storage -e TRACKER_SERVER=10.128.7.178:22122 -v /data/fdfs/storage:/var/fdfs  ccr.ccs.tencentyun.com/satan/fastdfs:6.06 storage
## 10.128.7.178 是我宿主机ip； 网络模式 host

3、防火墙设置

1.开放80,22122,23000端口,云服务器防火墙策略也要开(注意:如果关闭防火墙,云服务器策略也要开)

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=22122/tcp --permanent
firewall-cmd --zone=public --add-port=23000/tcp --permanent

2.重新加载配置

firewall-cmd --reload

3.查看防火墙锁开放的端口

  firewall-cmd --zone=public --list-ports

4、 访问nginx测试

10.128.7.128是我的宿主机

不能访问的请按下面方法排查

[root@WXGGFW-Ser04 app]# docker ps
CONTAINER ID   IMAGE                                       COMMAND                  CREATED        STATUS          PORTS     NAMES

## 分别进入容器 看看nginx 启动没有， 看看nginx conf配置 和 logs
[root@WXGGFW-Ser04 app]# docker exec -it f76d38455c33 /bin/bash
[root@WXGGFW-Ser04 /]# ps -ef|grep nginx
root          24       1  0 01:26 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx

[root@WXGGFW-Ser04 /]# tail -f /usr/local/nginx/logs/error.log

nginx服务进程正常启动。

错误原因：
进入nginx安装目录，查看nginx错误日志。

ERROR - file: …/tracker/fdfs_shared_func.c, line: 474, host “tracker” is invalid, error info: Unknown host

报错信息：
解决办法：

cd /etc/fdfs/
vim mod_fastdfs.conf
修改tracker_server参数

tracker_server={{ip}}:22122
