cas开局提示主机已存在无法添加集群

cas 7.0 0718

因操作失误，误删除集群，导致主机没有踢出集群，后再次加入新创的集群，提示：“主机xxx已存在”

1、可以看下cvk中是否有文件残留。查看 /etc/cvk下的cvm_info文件和/root/.ssh下的mhost文件，如果文件存在，需要手动删除。 

rm –rf cvm_info 

rm –rf mhost 

2、查看数据库是否有记录

[root@cvm ~]# mysql -u root -p

Enter password: 1q2w3e@4R

MariaDB [vservice]> SELECT * FROM TBL_HOST;  找到对应的表，需要进的表是 TBL_HOST

去对应的表删掉对应的id  

MariaDB [vservice]> DELETE FROM TBL_HOST WHERE ID=6;  

MariaDB [vservice]> DELETE FROM TBL_HOST WHERE ID=7;  

MariaDB [vservice]> exit

删除后再添加172.19.51.1这台可以加进来
