Greenplum-cc-web common errors during installation of the monitoring software

Err Error:
1.no pg_hba.conf entry for Host ":: 1", User "Gpmon", Database "Gpperfmon", SSL off
Solve:

pg_hba.conf增加：     host    gpperfmon   gpmon           ::1/128    trust (此处的trust应该为md5，否则后面会报错)

2.error: In the installation workload Manaager error, follow the prompts to view the log, found a machine crontab not installed
Solve:

install vixie-cron

3. Login Web Hint: Trust login is disabled.trust user Gpmon is not allowed to login Command Center
Describe:
Use psql-d gpperfmon-u gpmon-w Enter password to log in normally
View log:/home/greenplum-4.3-cc/instances/gpcc2/logs/gpmonws.log
We are from the log "Trust login not allowed." User Gpmon has trust login enabled "As you can see,
Gpmon is not a trust way to log, because the GP control in the configuration file gpperfmonui.conf the configuration Allow_trust_logon=false,
means not to be allowed to log on trust.
Modify pg_hba.conf to modify the trust to MD5

  host     all         gpmon         127.0.0.1/28    md5  host    gpperfmon       gpmon   ::1/128 md5 host gpperfmon gpmon 192.168.151.0/24 md5

  这里gpmon用户是不允许trust链接的，但是针对gpadminIII的使用，对于151段的配置还是可以使用trust，不冲突  host     all         all             192.168.151.0/24   trust
