环境:centos7.9 FastDFS_v5.07
FastDFS的配置文件主要有3个,分别是:tracker.conf、storage.conf、client.conf
,下面将来详细的讲解一下这3个配置文件。
[root@nginx fdfs]# cd /etc/fdfs/ [root@nginx fdfs]# mv tracker.conf.sample tracker.conf #先把刚安装完后默认的配置文件名改名 [root@nginx fdfs]# vim tracker.conf # is this config file disabled #是否启用这个配置文件 # false for enabled #
