# Setup Seafile cluster with NFS In a Seafile cluster, one common way to share data among the Seafile server instances is to us NFS. You should only share the files objects on NFS. Here we'll provide a tutorial about how and what to share. How to setup nfs server and client is beyond the scope of this wiki. Here are few references: - Ubuntu: [https://help.ubuntu.com/community/SettingUpNFSHowTo](https://help.ubuntu.com/community/SettingUpNFSHowTo) - CentOS: [http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html](http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html) Supposed your seafile server installation directory is `/data/haiwen`, after you run the setup script there should be a `seafile-data` directory in it. And supposed you mount the NFS drive on `/seafile-nfs`, you should follow a few steps: - Move the `seafile-data` folder to `/seafile-nfs`: ~~~ mv /data/haiwen/seafile-data /seafile-nfs/ ~~~ - On every node in the cluster, make a symbolic link to the shared seafile-data folder ~~~ cd /data/haiwen ln -s /seafile-nfs/seafile-data /data/haiwen/seafile-data ~~~ This way the instances will share the same `seafile-data` folder. All other config files and log files will remain independent.
