PPAS(Postgres Plus Advanced Server) HA 구성 with Corosync, Pacemaker, DRBD - step 2

6. Configuring Initialization options

I like to set runlevel to 3.

vi /etc/inittab

Change this line only (leaving everything else untouched):

id:3:initdefault:

I like remove some services from automatic initialization, to maintain only services that really will be used.

These are the active services that we'll need:

chkconfig --list | grep 3:sim

6.1 At this point, we need to reboot both nodes to apply configuration.

7. proxy 설정

vi /etc/yum.repos.d/epel.repo 의 모든

mirrorlist=https:// -> mirrorlist=http:// 로 변경 후

yum update -y 재시도

yum install -y pacemaker corosync drbd84 kmod-drbd84 heartbeat

* 아래와 같은 에러 나는 경우

Error: Package: cluster-glue-1.0.6-1.6.el5.x86_64 (clusterlabs)

           Requires: libltdl.so.3()(64bit)

Error: Package: cluster-glue-1.0.6-1.6.el5.x86_64 (clusterlabs)

           Requires: libnetsnmp.so.10()(64bit)

 You could try using --skip-broken to work around the problem

 You could try running: rpm -Va --nofiles --nodigest

아래 2개 패키지 설치 후 시도

rpm -Uvh http://ftp.muug.mb.ca/mirror/centos/6.6/os/x86_64/Packages/cluster-glue-libs-1.0.5-6.el6.x86_64.rpm

rpm -Uvh http://ftp.muug.mb.ca/mirror/centos/6.6/os/x86_64/Packages/cluster-glue-1.0.5-6.el6.x86_64.rpm

-> 아래 에러 발생하는 경우

error: Failed dependencies:

        perl-TimeDate is needed by cluster-glue-1.0.5-6.el6.x86_64

-> yum install perl-TimeDate

8. VM 복제

여기까지 node1 해놓고 node2 복제한다.

만약 ifconfig 해서 eth0 -> eth1, eth1 -> eth2 로 바뀌었다면 아래 링크 참고해서 해결한다.
