104 阅读 0 评论 69 点赞

我是靠谱客的博主顺心飞机，这篇文章主要介绍Linux sed安装etcd集群，现在分享给大家，希望可以做个参考。

P8-Etcd-Node01-Master
P8-Etcd-Node02-Slave-01
P8-Etcd-Node03-Slave-02

10.0.0.30
10.0.0.31
10.0.0.32

操作基本
systemctl start etcd
systemctl stop etcd
systemctl restart etcd
etcdctl member list

复制代码

hostnamectl set-hostname P8-Etcd-Node01-Master
#修改ip 10.0.0.30
cd /etc/sysconfig/network-scripts
sed -i '/.*BOOTPROTO=*/cBOOTPROTO="static"' ifcfg-ens33
sed -i '/.*IPADDR=*/cIPADDR=10.0.0.30' ifcfg-ens33
systemctl restart network

firewall-cmd --zone=public --add-port=2379/tcp --permanent
firewall-cmd --zone=public --add-port=2380/tcp --permanent
firewall-cmd --reload

yum install -y etcd
rpm -qa etcd
