OpenStack Docs: Pacemaker cluster stack
DBクラスタセットアップ実施後に、以下作業をコントローラ3台に実施する。
①Pacemaker & Corosyncインストール
$ sudo apt -y install crmsh
②設定ファイル編集
/etc/corosync/corosync.conf
totem {
version: 2
cluster_name: debian
token: 3000
token_retransmits_before_loss_const: 10
clear_node_high_bit: yes
crypto_cipher: none
crypto_hash: none
interface {
ringnumber: 0
bindnetaddr: 192.168.1.0
broadcast: yes
mcastport: 5405
ttl: 1
}
}
logging {
fileline: off
to_stderr: no
to_logfile: no
to_syslog: yes
syslog_facility: daemon
debug: off
timestamp: on
logger_subsys {
subsys: QUORUM

}
}
quorum {
provider: corosync_votequorum
expected_votes: 2
}
nodelist {
node {
ring0_addr: 192.168.1.51
nodeid: 1
}
node {
ring0_addr: 192.168.1.52
nodeid: 2
}
node {
ring0_addr: 192.168.1.53
nodeid: 3
}
}
③Corosync再起動
$ sudo systemctl stop corosync $ sudo systemctl start corosync
④動作確認
$ sudo corosync-cfgtool -s Printing ring status. Local node ID 1 RING ID 0 id = 192.168.1.51 status = ring 0 active with no faults
※statusがno faultsであること
$ sudo corosync-cmapctl runtime.totem.pg.mrp.srp.members runtime.totem.pg.mrp.srp.members.1.config_version (u64) = 0 runtime.totem.pg.mrp.srp.members.1.ip (str) = r(0) ip(192.168.1.51) runtime.totem.pg.mrp.srp.members.1.join_count (u32) = 1 runtime.totem.pg.mrp.srp.members.1.status (str) = joined runtime.totem.pg.mrp.srp.members.2.config_version (u64) = 0 runtime.totem.pg.mrp.srp.members.2.ip (str) = r(0) ip(192.168.1.52) runtime.totem.pg.mrp.srp.members.2.join_count (u32) = 1 runtime.totem.pg.mrp.srp.members.2.status (str) = joined runtime.totem.pg.mrp.srp.members.3.config_version (u64) = 0 runtime.totem.pg.mrp.srp.members.3.ip (str) = r(0) ip(192.168.1.53) runtime.totem.pg.mrp.srp.members.3.join_count (u32) = 1 runtime.totem.pg.mrp.srp.members.3.status (str) = joined
※statusがjoinedであること
⑤Pacemaker再起動
$ sudo systemctl restart pacemaker
⑥Pacemaker起動確認
$ sudo crm_mon -1 Last updated: Sat Nov 4 00:27:14 2017 Last change: Sat Nov 4 00:25:10 2017 by hacluster via crmd on cnt1 Stack: corosync Current DC: cnt1 (version 1.1.14-70404b0) - partition with quorum 3 nodes and 0 resources configured Online: [ cnt1 cnt2 cnt3 ]
※Onlineに3台表示されること
⑦Pacemaker設定
cnt1のみで以下を実施
プロパティ設定
$ sudo crm configure property pe-warn-series-max="1000" pe-input-series-max="1000" pe-error-series-max="1000" cluster-recheck-interval="5min" no-quorum-policy="ignore" stonith-enabled=false $
VIP設定
$ sudo crm configure primitive vip-public ocf:heartbeat:IPaddr2 params ip="192.168.0.50" cidr_netmask="24" op monitor interval="30s" $ sudo crm configure primitive vip-local ocf:heartbeat:IPaddr2 params ip="192.168.1.50" cidr_netmask="24" op monitor interval="30s"
