如：server_host=172.16.1.249

问题14

postgresql启动不起来，首先查看scm的日志，然后看db.log 
FATAL: pre-existing shared memory block (key 7432001, ID 0) is still in use
HINT:  If you're sure there are no old server processes still running, remove the shared memory block or just delete the file "postmaster.pid".

解决方法：

1、关闭·一切关于postgresql的进程
2、查看日志
rm -r /var/lib/cloudera-scm-server-db/data/postmaster.pid
