System V Init Script
by James Bensley 03 Jun '09

03 Jun '09

Hey Listees, I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3, 4 and 5. However when I wrote the script I only ever added a "start" and "stop" clause to it (why I can't remember?), now I need to add a "restart" clause but I'm having an issue. I have pasted the code below from my "restart" clause but from what I can tell, it is killing the app but not restarting it, I think because the killing process is still in action so when it start the app again it just gets killed straight away. If I enter "/etc/init.d/my_app restart" the app is terminated but does not start again, entering "/etc/init.d/my_app start" immediately after fires it up straight away so there is no problem there; can someone suggest a better way as my scripting is very begginnerish (if thats a word) and I don't doubt for a second I am doing this in a very inefficient manner: <snipety snip snip> restart) echo -n "Stopping my_app: " pgrep my_app | while read PIDS; do # I have chosen this method because my_app spawns various child processes kill -9 $PIDS # and they all need to DIE! (Killing the parent process would kill the child processes done # however there are actually two parent processes so this seems like a good idea?) echo -n "Starting my_app: " /usr/local/my_app/sbin/my_app_bin & exit $? ;; <snip snap snorum> Any input is greatly appreciated!

Re: [CentOS] [OT] Simple Shell Script (while loop)

Thanks guys the "continue" command was what I was looking for. Also to those who pointed out the lack of quotation marks around the string, they are on my original script but somehow vanished during the copy and paste operation between my shell window and browser...werid?!?! Still If I hadn't of had those then you would of corrected me so thanks for that! Nice work listee's ;) -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT/MU/U dpu s: a--> C++>$ U+> L++> B-> P+> E?> W+++>$ N K W++ O M++>$ V- PS+++ PE++ Y+ PGP t 5 X+ R- tv+ b+> DI D+++ G+ e(+++++) h--(++) r++ z++ ------END GEEK CODE BLOCK------

CentOS 5.3 SuperMicro x7sbi AHCI
by Ron Lorah 03 Jun '09

03 Jun '09

Greetings, Wondering if anyone could assist with this. I have many SuperMicro 5015B-MTB servers. These all have the X7SBi Motherboards. After upgrading to CentOS 5.3 the Hard Drive LED's on some of the servers started blinking red(drive fail) but all is functioning normally. All servers are running raid 1 arrays with MDADM. Primary drive does not blink, but all others do including spares. These boards use the Intel ICH9R chipset. AHCI is enabled. When AHCI is disabled, drives stop blinking, but drives are then detected as hda,hdb,etc. and server takes a huge performance hit. All Servers have Western Digital SATAII 320G RE2 Drives. So far: I have reloaded Kernels Tried CentOS plus Kernels Flashed the Bios Replaced Backplane The funny thing is, not all servers are affected. If anyone has any ideas or could just point me in the right direction, it would be extremely appreciated. It's an annoyance more than anything else. Thx, ~Ron

Local Host Routing
by Al Sparks 02 Jun '09

02 Jun '09

I have, a machine running RHEL ES 4.7 with 2 physical interfaces. eth0 Link encap:Ethernet HWaddr 00:14:22:1C:B4:EA inet addr:10.7.13.61 Bcast:10.7.13.255 Mask:255.255.255.0 inet6 addr: fe80::214:22ff:fe1c:b4ea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:590936429 errors:0 dropped:0 overruns:0 frame:0 TX packets:590246457 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:361946964 (345.1 MiB) TX bytes:3358327885 (3.1 GiB) eth1 Link encap:Ethernet HWaddr 00:14:22:1C:B4:EB inet addr:10.254.214.16 Bcast:10.254.214.255 Mask:255.255.255.0 inet6 addr: fe80::214:22ff:fe1c:b4eb/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:423509 errors:0 dropped:0 overruns:0 frame:0 TX packets:19440 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:35948215 (34.2 MiB) TX bytes:2850651 (2.7 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:115612666 errors:0 dropped:0 overruns:0 frame:0 TX packets:115612666 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:96931918 (92.4 MiB) TX bytes:96931918 (92.4 MiB) By default both interfaces route through the default gateway. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.7.13.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.254.214.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 0.0.0.0 10.7.13.1 0.0.0.0 UG 0 0 0 eth0 The LAN, 10.254.214.0/24 that eth1 is a part of, is configured to not route at all. (Actually it's a VLAN, if that's germane). However, when I remove the route entry with: # route del -net 10.254.214.0 netmask 255.255.255.0 I lose connectivity with the nodes on the LAN. When I do an $ nmap -sP 10.254.214.0/24 the only thing that shows up is Host 10.254.214.16 appears to be up which is the IP address of eth1. I shouldn't need a routing gateway to reach these devices. In addition, even when the routing entry is there (or not) a ping from eth1 $ ping -I eth1 10.7.13.1 gives me destination unreachable, so the entry is pointless. BTW, $ ping -I eth0 10.7.13.1 works fine as it should. I guess it's not a big deal. If it works don't fix it. But I'm still curious. Any ideas? === Al

I was hoping *you* (some of you are sysadmins at companies that also use RHEL, not just CentOS) are better suited to already know whether TUV has or has not implemented that schema. Sigh. Mailing lists. Back in 1996, Marc Ewing answered me personally to a hardware issue I had with RH 3.0.3, but in 2009 people prefer to twaddle and give non-answers. Sigh.
