I'm trying to write an Nginx config with the following semantics, expressed in hopefully-readable psuedo-config:

location /dir1/ /dir2/ {
  if (matches a .php file) {
    serve with php
  } else if (matches a non-.php file) {
    serve as static content
  } else {
    404
  }
} else {
  serve with /index.php
}

How do I do this? I have a decent sense of Apache configuration, but I don't have a good enough grasp on Nginx to sort out the semantics of try_files and location matching and internal redirects and stuff. Any tips on how I should structure this?

For reference, the mod_rewrite-based configuration I'm currently using with Apache is

# Any URL not corresponding to a directory gets rewritten to index.php
RewriteCond $1 !^dir1/
RewriteCond $1 !^dir2/
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

# Allow access to files in any of the directories
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ - [L]

# If either step above resulted in a php file, process it
<FilesMatch "\.php$">
    SetHandler application/x-httpd-php
</FilesMatch>
php url nginx static-content

I have two Linux systems, both running Debian Squeeze. Versions of (I think) the stuff involved are:

  kernel: 2.6.32-5-xen-amd64
  ii  nfs-kernel-server                   1:1.2.2-4squeeze2            support for NFS kernel server
  ii  libnfsidmap2                        0.23-2                       An nfs idmapping library
  ii  nfs-common                          1:1.2.2-4squeeze2            NFS support files common to client and server
  ii  portmap                             6.0.0-2                      RPC port mapper

(The client doesn't have nfs-kernel-server involved.)

I have a directory with ACLs:

# file: dirname
# owner: jon
# group: foogroup
# flags: -s-
user::rwx
user:www-data:rwx
group::r-x
group:foogroup:rwx
mask::rwx
other::r-x
default:...

There are two users, neither one of which owns the directory:

uid=3001(jake) gid=3001(jake) groups=3001(jake),104(wheel),3999(foogroup)
uid=3005(nic) gid=3005(nic) groups=3005(nic),3999(foogroup)

The jake user can create files in the directory without issues. The nic user can't. All UIDs/GIDs are the same on the client and server. I've verified (packet sniffing) that the right uids/gids get sent via AUTH_UNIX are correct-- uid=gid=3005, auxiliary gids=3005,3999-- and that the server replies with NFS3ERR_ACCESS, which the kernel on the client maps to EACCES (Permission denied).

Can anyone help me here?

I'm trying to mount NFS filesystems over an OpenVPN link on Debian Squeeze. The problem is that the default layout of init scripts and such tries to mount the NFS filesystems before bringing up the VPN. With the default configuration, the system just hangs during boot.

My OpenVPN configuration is standard (a .conf file in /etc/openvpn), and my fstab is

10.123.4.5:/path1 /localpath1 nfs rw,acl,relatime,soft,intr 0 0
10.123.4.5:/path2 /localpath2 nfs rw,acl,relatime,soft,intr 0 0
10.123.4.5:/path3 /localpath3 nfs rw,acl,relatime,soft,intr 0 0

I tried adding openvpn vpnname to the stanza for my physical interface (eth1) in /etc/network/interfaces, which makes it try to bring up the VPN when it brings up eth1, but it still tries to mount NFS first.

Shutting down is also an issue: with the default configuration, OpenVPN gets stopped before services which use the NFS mounts, so the halt/reboot hangs.

How can I get this to work? Clean "this is the 'right' way" solutions preferred; pragmatic solutions accepted. :)

What are the best practices for using an SSD on a Linux workstation?

Specifically, I'm interested in:

  1. What mounts I should put on the SSD and what I should keep on my HDD
  2. What filesystem I should use for what I do put on the SSD
  3. Whether it's okay to use LVM between the filesystems and the SSD
  4. What do I need to do to get things like TRIM to work (and whether it matters)

Right now, my mounts are 20G for /, 200M for /boot, 15G for /home, 5G for /srv, 5G for /tmp, and 10G for /var. Everything uses ext3 on standard LVM, and there's a ton of free space both on the filesystems and on the disks (500G HDD and 64G SSD.) I have "enough" RAM, so I shouldn't need to swap; OTOH, I could always increase swappiness to swap more and use more RAM for the page cache.

Pretty much everything about the setup is mutable; I don't need to do whatever I do live. (It would be nice to be able to grow things live later, though.)

Also, if there's anything I'm forgetting to consider, please tell me. :)
