etcd集群配置

官方參考

etcd github：

etcd 集群配置官方文件 /blob/master/documentation/op-guide/clustering.md

開機集群啟動

#etcd_auth_token="******"開機啟動配置

/usr/lib/systemd/system/etcd.service

[unit]

description=etcd server
after=network.target
after=network-online.target
wants=network-online.target
[service]
type=notify
workingdirectory=/var/lib/etcd/
environmentfile=-/etc/etcd/etcd.conf
user=etcd
# set gomaxprocs to number of processors
execstart=/bin/bash -c "gomaxprocs=$(nproc) /usr/bin/etcd --name=\"$\" --data-dir=\"$\" --listen-client-urls=\"$\""
restart=on-failure
limitnofile=65536
[install]
wantedby=multi-user.target

yum install etcd -y

/etc/etcd/etcd.conf etcd的配置檔案

/usr/lib/systemd/system/etcd.service

[root@docker111 ~]# rpm -ql etcd|grep -v /man/

/etc/etcd
/etc/etcd/etcd.conf
/usr/bin/etcd
/usr/bin/etcdctl
/usr/lib/systemd/system/etcd.service
/usr/share/doc/etcd-3.3.11

/usr/lib/systemd/system/etcd.service檔案中可以修改配置檔案位置

environmentfile=-/etc/etcd/etcd.conf

需要修改的配置

etcd_name="etcd112"

etcd_listen_peer_urls=""
etcd_listen_client_urls=""
##[clustering]
#etcd_initial_advertise_peer_urls=""
etcd_advertise_client_urls=""
