FastDFS高可用集群部署安装
1、环境信息：
| 服务器 | 部署服务 |
|---|---|
| 16.32.15.200 | Tracker(调度工作)、Storage(存储)、Nginx、Keepalived |
| 16.32.15.201 | Tracker(调度工作)、Storage(存储)、Nginx、Keepalived |
| 16.32.15.202 | 以上两台的VIP地址 |
2、部署FastDFS
正常部署 FastDFS 此处省略,参考：FastDFS单节点部署安装
3、tracker节点配置
主要检查以下配置项，两台服务器配置保持一致
cat /etc/fdfs/tracker.conf
# 是否启用配置文件,false表示生效
disabled=false
# 提供服务端口号
port=22122
# 存储数据和日志目录
base_path=/home/fastdfs/tracker
# 0:轮循 1:指定组 2:负载平衡
store_lookup=2
启动tracker节点，两台服务器同步操作
fdfs_trackerd /etc/fdfs/tracker.conf restart
netstat -anpt |grep 22122
4、storage节点配置
主要检查以下配置项，两台服务器配置保持一致
cat /etc/fdfs/storage.conf
# 是否启用配置文件,false表示生效
disabled=false
group_name=group1
port=23000
base_path=/home/fastdfs/storage
store_path0=/home/fastdfs/storage
# 存储路径个数,需要和store_path个数匹配
store_path_count=1
# tracker节点IP+端口
tracker_server=16.32.15.200:22122
tracker_server=16.32.15.201:22122
# http端口号
http.server_port=8888
启动storage节点，两台服务器同步操作
fdfs_storaged /etc/fdfs/storage.conf restart
netstat -anpt |grep 23000
5、查看集群信息
fdfs_monitor /etc/fdfs/storage.conf

6、nginx模块配置，两台服务器配置保持一致
cat /etc/fdfs/mod_fastdfs.conf
base_path=/home/fastdfs/storage
store_path0=/home/fastdfs/storage
tracker_server=16.32.15.200:22122
tracker_server=16.32.15.201:22122
storage_server_port=23000
7、上传文件检查两台节点是否同步
cat /etc/fdfs/client.conf
base_path=/home/fastdfs/storage
tracker_server=16.32.15.200:22122
tracker_server=16.32.15.201:22122
fdfs_upload_file /etc/fdfs/mod_fastdfs.conf [上传文件名]
9、两台服务器安装nginx服务并配置keepalived虚拟地址
省略… … 最后实现如下：
- 16.32.15.200 Nginx主
- 16.32.15.201 Nginx备
- 16.32.15.202 keepalived虚拟地址
10、FastDFS高可用验证
上传图片文件
fdfs_upload_file /etc/fdfs/mod_fastdfs.conf /root/jg.png
![[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-M7YZVNSC-1686547124371)(D:\MD归档文档\IMG\image-20230227121817978.png)]](http://img.e-com-net.com/image/info8/e3a9affa2cba4da5923ed435cb74acf3.jpg)
浏览器访问图片：http://IP:Port/group1/M00/00/00/ECAPyGP8n2aAfcY6AAONqU5ReXo078.png
此刻进行主备切换，把虚拟IP地址切换到备机,再进行访问
