Howto run Apache web server on Linux read-only root file system

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I'm running the Apache web server 2.2.17 on an openSUSE 11.4 system.

Out of security reasons I need to have the root file system mounted read-only. 
/var is mounted read/write on a separate partition, thus the log files do not cause any problem.

When booting my system I get the following errors, due to read-only rootfs.


mv: inter-device move failed: `/tmp/apache2.PLbqAdT67tqh' to 
`/etc/apache2/sysconfig.d/loadmodule.conf'; unable to remove target: Read-only file system
/usr/share/apache2/get_module_list: line 113: /etc/apache2/sysconfig.d/global.conf: Read-only file 
system
/usr/share/apache2/get_module_list: line 114: 3: Bad file descriptor
/usr/share/apache2/get_module_list: line 136: 3: Bad file descriptor
/usr/share/apache2/get_module_list: line 140: 3: Bad file descriptor
/usr/share/apache2/get_module_list: line 141: 3: Bad file descriptor
/usr/share/apache2/get_module_list: line 144: 3: Bad file descriptor
/usr/share/apache2/get_module_list: line 151: 3: Bad file descriptor
/usr/share/apache2/get_includes: line 15: /etc/apache2/sysconfig.d/include.conf: Read-only file 
system
/usr/share/apache2/get_includes: line 16: 3: Bad file descriptor
/usr/share/apache2/get_includes: line 43: 3: Bad file descriptor


Does anybody have some experience with that topic and can provide a solution?

I came up with two ideas. Either link the affected files to some place on var or try to remount 
rootfs rw in the apache2 init script and afterwards mount it ro again.

Any suggestions, which idea to prefer and/or howto implement it in a reasonable way?


Thanks,
Moni
