vcsa就是一个suse linux，会内置一个PostgreSQL数据库，那么如何修改数据库用户密码呢？
首先通过22端口远程连入suse linux

首先输入shell就来到了熟悉的linux命令行。
Command> shell
Shell access is granted to root
root@vcsa7 [ ~ ]#
其次查看下vc连库的密码：
root@vcsa7 [ ~ ]# cat /etc/vmware-vpx/vcdb.properties
driver = org.postgresql.Driver
dbtype = PostgreSQL
url = jdbc:postgresql://localhost:5432/VCDB?sslmode=disable
username = vc
password = 4Zj#S^qyY{oi9}!7
password.encrypted = false
可以看到密码是明文，直接修改即可，也可打开下面的encrypted,密码就变为加密的乱码了。
root@vcsa7 [ ~ ]# psql -U vc -d postgres -W
Password for user vc:
