4 <h1>Setting up clustered FTP</h1>
7 Configure CTDB as above and set it up to use public ipaddresses.<br>
8 Verify that the CTDB cluster works.
10 <h2>Configuration</h2>
12 Setting up a vsftpd cluster is really easy.<br>
13 Configure vsftpd on each node on the cluster.<br><br>
14 Set up vsftpd to export directories from the shared cluster filesystem.
16 <h2>/etc/sysconfig/vsftpd</h2>
18 Create the file /etc/sysconfig/vsftpd with the content :
20 CTDB_MANAGES_VSFTPD=yes
23 Disable vsftpd in chkconfig so that it does not start by default. Instead CTDB will start/stop vsftdp as required.
28 <h2>Events script</h2>
30 The CTDB distribution already comes with an events script for vsftp in the file /etc/ctdb/events.d/40.vsftpd<br><br>
31 There should not be any need to edit this file.
34 <h2>Restart your cluster</h2>
35 Next time your cluster restarts, CTDB will start managing the vsftp service.<br><br>
36 If the cluster is already in production you may not want to restart the entire cluster since this would disrupt services.<br>
38 Insted you can just disable/enable the nodes one by one. Once a node becomes enabled again it will start the vsftp service.<br><br>
40 Follow the procedure below for each node, one node at a time :
42 <h3>1 Disable the node</h3>
43 Use the ctdb command to disable the node :
48 <h3>2 Wait until the cluster has recovered</h3>
50 Use the ctdb tool to monitor until the cluster has recovered, i.e. Recovery mode is NORMAL. This should happen within seconds of when you disabled the node.
55 <h3>3 Enable the node again</h3>
57 Re-enable the node again which will start the newly configured vsftp service.
