3、1 k8s集群手动部署笔记之Etcd配置-node节点配置

配置其他节点的Etcd

为了方便集群管理,配置ssh信任证书.可以直接免密码登录其他节点

ssh-keygen一直回车即可
[root@master ~]# ssh-keygen
[root@master ~]# ssh-copy-id [email protected]
[root@master ~]# ssh-copy-id [email protected]

配置文件复制到其他节点

在其他节点创建k8s部署配置文件统一存放位置

[root@node1 ~]# mkdir -p /opt/kubernetes/{bin,cfg,ssl}
[root@node2 ~]# mkdir -p /opt/kubernetes/{bin,cfg,ssl}

Etcd二进制文件,配置，证书复制到其他节点

node1
[root@master ~]# scp -r /opt/kubernetes/bin/ root@192.168.10.61:/opt/kubernetes/
[root@master ~]# scp -r /opt/kubernetes/cfg/ root@192.168.10.61:/opt/kubernetes/
[root@master ~]# scp -r /opt/kubernetes/ssl/ root@192.168.10.61:/opt/kubernetes/
[root@master ~]# scp /usr/lib/systemd/system/etcd.service root@192.168.10.61:/usr/lib/systemd/system/

node2
[root@master ~]# scp -r /opt/kubernetes/bin/ root@192.168.10.62:/opt/kubernetes/
[root@master ~]# scp -r /opt/kubernetes/cfg/ root@192.168.10.62:/opt/kubernetes/
[root@master ~]# scp -r /opt/kubernetes/ssl/ root@192.168.10.62:/opt/kubernetes/
[root@master ~]# scp /usr/lib/systemd/system/etcd.service root@192.168.10.62:/usr/lib/systemd/system/ 

在其他节点修改etcd配置文件:

node1修改

注意修改ETCD_NAME和当前节点node1的ip:192.168.10.61
[root@node1 ~]# vi /opt/kubernetes/cfg/etcd

ETCD_NAME="etcd02"

启动etcd看看
[root@node1 ~]# systemctl start etcd

启动成功嘿嘿,加入开机启动
[root@node1 ~]# ps -ef |grep etcd

node2修改

基本跟上面一样
[root@node2 ~]# vi /opt/kubernetes/cfg/etcd

ETCD_NAME="etcd03"

启动并设置开机启动
[root@node2 ~]# systemctl start etcd                                                  
[root@node2 ~]# systemctl enable etcd

正常启动
[root@node2 ~]# ps -ef |grep etcd
