PostgreSql报错 FATAL: data directory “/opt/huawei/install/data/db1“ has group or world access

PostgreSql报错 FATAL: data directory “/opt/huawei/install/data/db1“ has group or world access

发生这个错误的一般原因是：虚拟机突然断电 然后再启PostgreSql 就起不来了

看报错：
omm@node1 ~]$ gs_ctl start -D “/opt/huawei/install/data/db1/”

说是：data directory “/opt/huawei/install/data/db1” has group or world access
说明 /opt/huawei/install/data/db1 权限错误

解决方法

cd /opt/huawei/install/data
chown -R omm:dbgrp db1
chmod -R 0700 db1

再重启

gs_ctl start -D "/opt/huawei/install/data/db1/"

服务器就应该能起来了
