saltstack（主机改名）
已存在salt中的机器，为了规范，需要将这批主机改名
操作流程：在master把这批机器剔除；然修改这批机器的主机名、在/etc/salt目录下、用mv把minion_id和pki的目录重命名、重启salt-minion服务（在mster段能再次监控到这台主机后、可把上面重命名的文件删除）
环境：http://www.cnblogs.com/zzzhfo/p/6126223.html
把salt-client-01改名为salt-minion-01
- 在salt-server上把salt-client-01剔除
[root@salt-server /]# salt-key -L Accepted Keys: salt-client-01 salt-client-02 Denied Keys: Unaccepted Keys: Rejected Keys: [root@salt-server /]# salt-key -d ‘salt-client-01‘ -y Deleting the following keys: Accepted Keys: salt-client-01 Key for minion salt-client-01 deleted. [root@salt-server /]# salt-key -L Accepted Keys: salt-client-02 Denied Keys: Unaccepted Keys: salt-client-01
Rejected Keys:
修改主机名
[root@salt-client-01 /]# cat /etc/sysconfig/network #重启生效 NETWORKING=yes HOSTNAME=salt-minion-01 [root@salt-client-01 /]# hostname salt-minion-01 [root@salt-client-01 /]# bash
删除minion_id和pki（建议使用mv命令）
[root@salt-minion-01 /]# cd /etc/salt/ [root@salt-minion-01 salt]#mv minion_id minion_id.bak [root@salt-minion-01 salt]# mv pki pki.bak [root@salt-minion-01 salt]# /etc/init.d/salt-minion restart Stopping salt-minion daemon: [ OK ] Starting salt-minion daemon: [ OK ] [root@salt-minion-01 salt]# ls minion minion.d minion_id minion_id.bak pki pki.bak

error :salt主缓存节点的公钥,这盐奴才将等待10秒前试图认证

在master端重新认证（可能存在延迟、多刷新几次）
[root@salt-server master]# salt-key -L Accepted Keys: salt-client-02 Denied Keys: Unaccepted Keys: salt-client-01 salt-minion-01 Rejected Keys:
[root@salt-server master]# salt-key -a ‘salt-minion-01‘ -y The following keys are going to be accepted: Unaccepted Keys: salt-minion-01 Key for minion salt-minion-01 accepted. [root@salt-server master]# salt-key -L Accepted Keys: salt-client-02 salt-minion-01 Denied Keys: Unaccepted Keys: salt-client-01 Rejected Keys: [root@salt-server master]# salt ‘*‘ test.ping salt-minion-01: True salt-client-02: True
上面用salt-key -L 查看到salt-client-01在等待认证，是因为缓存的原因
[root@salt-server master]# pwd /etc/salt/pki/master [root@salt-server master]# ll minions #通过认证的key total 8 -rw-r--r--. 1 root root 451 Sep 28 00:20 salt-client-02 -rw-r--r--. 1 root root 451 Sep 29 00:41 salt-minion-01 [root@salt-server master]# ll minions_pre 等待认证的key total 4 -rw-r--r--. 1 root root 451 Sep 29 00:35 salt-client-01 [root@salt-server master]# cd minions_pre [root@salt-server minions_pre]# ls salt-client-01 #把它删除 再次查看就不会存在了 [root@salt-server minions_pre]# rm -rf salt-client-01 [root@salt-server minions_pre]# ls [root@salt-server minions_pre]# salt-key -L Accepted Keys: salt-client-02 salt-minion-01 Denied Keys: Unaccepted Keys: Rejected Keys:
