Hello, I managed to setup a webcluster using this tutorial: http://howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu8.04 . But I planned to host the mysql server used by the clustered apps on the loadb. Can you tell me if there is a posibility to connect from a node (all nodes) to the active loadb (using the virtual interface) considering that IP address is bound to lo:0? I tried adding a route, but without success. Hope I explained everything well enough, Thank you.
Hello, Thanks for the reply, here is the output of ifconfig: Code: eth0 Link encap:Ethernet HWaddr 00:30:48:D4:D4:66 inet addr:x.9.41.3 Bcast:85.9.41.255 Mask:255.255.255.0 inet6 addr: fe80::230:48ff:fed4:d466/64 Scope:Link UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:216347331 errors:0 dropped:0 overruns:0 frame:0 TX packets:236584330 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:28211839962 (26.2 GiB) TX bytes:295732341723 (275.4 GiB) Base address:0x2000 Memory:d8000000-d8020000 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:29511345 errors:0 dropped:0 overruns:0 frame:0 TX packets:29511345 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:23775772921 (22.1 GiB) TX bytes:23775772921 (22.1 GiB) The virtual IP of the cluster (where www is) is x.9.22.128.
It is running: Code: IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP x.9.41.2:80 rr -> x.9.41.5:80 Route 0 0 0 -> x.9.41.6:80 Route 1 0 0 -> x.9.41.7:80 Route 0 0 0 Code: 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:6a:4c:97 brd ff:ff:ff:ff:ff:ff inet x.9.41.3/24 brd x.9.41.255 scope global eth0 inet x.9.41.2/24 brd x.9.41.255 scope global secondary eth0 inet6 fe80::20c:29ff:fe6a:4c97/64 scope link valid_lft forever preferred_lft forever Code: ldirectord for /etc/ha.d/ldirectord.cf is running with pid: 3221 Code: master running (ipvs_syncmaster pid: 3308) So .2 is the virtual ip and .3 is the address of the server. The cluster is working, I just want to access other services on that machine (the active loadb). By the way, are these daemons eating a lot of resources or I can store here a mysql server? The application (website) is getting a lot of hits in some periods of time. The server is a quad core xeon E5450 @ 3.00GHz with 3 gigs of ram and at the moment is hosting that application (magento based). As I saw in the "bad-moments", mysql is not eating that much resources as apache (because of magento's code). Thank you for your help.. and awsome site
