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]

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-jB0Mvty3-1686547124370)(D:\MD归档文档\IMG\image-20230227115824232.png)]$

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

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-M7YZVNSC-1686547124371)(D:\MD归档文档\IMG\image-20230227121817978.png)]$

浏览器访问图片：http://IP:Port/group1/M00/00/00/ECAPyGP8n2aAfcY6AAONqU5ReXo078.png

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Swoc04Ke-1686547124371)(D:\MD归档文档\IMG\image-20230227122142304.png)]$

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-ALfG6IWj-1686547124372)(D:\MD归档文档\IMG\image-20230227122244446.png)]$

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-tNqsfYhB-1686547124372)(D:\MD归档文档\IMG\image-20230227122341433.png)]$

此刻进行主备切换，把虚拟IP地址切换到备机,再进行访问

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-zQAKiLmj-1686547124372)(D:\MD归档文档\IMG\image-20230227122633374.png)]$
