error building apr-util spec file
by Tim Dunphy 23 Mar '15

23 Mar '15

Hey guys, I'm trying to create an apache 2.4.12 rpm file. But in order to do that I need to create an apr-util rpm of a recent enough version to support it. So running the rpmbuild command against the spec file I'm getting this error: checking db1/db.h usability... no checking db1/db.h presence... no checking for db1/db.h... no checking db.h usability... no checking db.h presence... no checking for db.h... no checking for Berkeley DB 1 in the standard places... checking db_185.h usability... no checking db_185.h presence... no checking for db_185.h... no *checking for Berkeley DB... not found* *configure: error: Berkeley DB not found.* error: Bad exit status from /var/tmp/rpm-tmp.yh0jGv (%build) It's claiming that Berkeley DB isn't installed. But to me it looks like I have the right libraries: [root@repo:~] #rpm -qa | grep db4 libdb4-utils-4.8.30-13.el7.x86_64 libdb4-devel-static-4.8.30-13.el7.x86_64 libdb4-4.8.30-13.el7.x86_64 libdb4-devel-4.8.30-13.el7.x86_64 This is the part of the spec file that calls for db4: %configure --with-apr=%{_prefix} \ --includedir=%{_includedir}/apr-%{apuver} \ --with-ldap --without-gdbm \ --with-sqlite3 --with-pgsql --with-mysql --with-freetds --with-odbc \ --with-berkeley-db \ --with-crypto --with-openssl --with-nss \ --without-sqlite2 So my questions for today are, do I need to provide a path to the --with-berkeley-db flag? If so, how do I determine the path to give it? Lastly, is db4 really necessary to the build of apr-util? Would it be completely wrong just to build the rpm without it?

Firewalld IP in multiple zones
by Tim 22 Mar '15

22 Mar '15

Hi, I would like to know what will happen when I add 192.168.3.0/24 to trusted zone, but 192.168.3.1/32 to public zone. 192.168.3.1 is the gateway and should not have access to other services in that network. However, will it be blocked or trusted to access services which are allowed in the trusted zone? What's firewalld's rule? Deny before allow? Thanks in advance Tim

How does Linux choose ARP request source IP?
by Chris Adams 21 Mar '15

21 Mar '15

I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This is probably not related to my problem, but I just thought it was odd. Is there a way to control this? -- Chris Adams <linux(a)cmadams.net>

I am running Centos 6.6 US version and occasionally need to write emails and documents in Chinese using simplified characters. I have installed the ibus input system but do not find it very efficient having used the Google Pinyin keyboard on my Android phones and tablet. Which input system is recommended for writing Simplified Chinese? Hakan

C7 http ITK
by Steven Stern 21 Mar '15

21 Mar '15

I've been trying to get the mod_itk module installed on Centos 7. The package is in epel, but there's an error once it's installed "mod_access_compat.so undefined symbol ap_hook_check_access". Can anyone point me to a set of RPMs that will let me run itk or another C7 ready tool that will easily run each vhost as a different user? -- -- Steve

Also as I indicated in an early message in this thread, if you look at /etc/inittab, where one used to set the runlevel, you will see the details of how to do this on a C7 machine.

I am just providing this information in case someone else does something similar. The situation is this. I have a KVM guest that I keep as a clone template. It has one virtio disk of 32GB that is configured as an LVM partition with several lvs. I cloned this system to create an off-site backup host for our fax server. The archives of which exceeds 32GB by some margin. My requirement therefore was to create the necessary additional storage (2 x 32Gb virtio disks) and attach them to the cloned system. Initially this worked as it has in the past. However, I ran into a problem on the new guest when adding a new lv using the space from the new virtual disks that I had added to the volume group defined on the guest. And this is where I made my mistake. Instead of removing the lv first and then removing the virtio disks from the vg I deleted the disks from the guest. This meant that the guest LVM manager was looking for those drives whenever it was rebooted. If the drives that I added back in subsequent trials were not partitioned then they were not found by the lvm manager and the system booted. If the re-added disks were partitioned then the lvm manager found them, but they were not the disks expected. That probably tripped some sort of security or consistency check and that caused the kernel panic. The fix was to boot the system without the added disks. Then login and run the lvm utilities to remove the dangling lv, also remove the missing pvs from the vg, and then shutdown. Once this was done adding new partitioned virtio disks to the guest proceeded as expected and the problem disappeared from the next boot. -- *** E-Mail is NOT a SECURE channel *** James B.

multiple memcached buckets in CentOS 7
by Tim Dunphy 19 Mar '15

19 Mar '15

Hey guys, OK so I'm pretty familiar with how to edit an init script for memcached so that I can get multiple memcached 'buckets' when starting up the service. The init script would ususally have multiple lines such as these under the start function: # cache_block /usr/local/bin/memcached -d -m 128 -l `hostname -i` -p 11318 -u daemon -c 8172 -v 2>> /tmp/memcached.log # cache_filter /usr/local/bin/memcached -d -m 512 -l `hostname -i` -p 11319 -u daemon -c 8172 -v 2>> /tmp/memcached.log # cache_form /usr/local/bin/memcached -d -m 128 -l `hostname -i` -p 11320 -u daemon -c 8172 -v 2>> /tmp/memcached.log Now, under CentOS 7, I see we have two files controlling memcached under the new sysctl system. At least, using sysctl is new to me! I see we have this file: [root@web1:~] #cat /usr/lib/systemd/system/memcached.service [Unit] Description=Memcached Before=httpd.service After=network.target [Service] Type=simple EnvironmentFile=-/etc/sysconfig/memcached ExecStart=/usr/bin/memcached -u $USER -p $PORT -m $CACHESIZE -c $MAXCONN $OPTIONS [Install] WantedBy=multi-user.target And we have this one under sysconfig: [root@web1:~] #cat /etc/sysconfig/memcached PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="" So I'm trying to figure out how to achive the same effect that I would under the old init script way of doing things. Can someone please give me an example of how to get the same thing done under the new system? Thanks, Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B
