修改gp叢集主機名稱
阿新 • • 發佈：2019-02-11
在某些情況下，特別是在前期沒規劃好的情況下，後期執行過程中會遇到需要修改hostname&ip的情況，現狀遇到的情況是需要調整hostname，對於某些已經投產或者的叢集類的環境，修改這些資訊尤為麻煩。
大體步驟：
0. 維護模式開啟資料庫，修改配置表 gp_segment_configuration 的hostname和address欄位為新主機名稱；
1、停庫，關閉維護模式；
2、修改/etc/sysconf/network和/etc/hosts檔案，使用新的主機名稱，重啟主機；
3、開啟資料庫並檢查。
以下是記錄：

大體步驟：
0. 維護模式開啟資料庫，修改配置表 gp_segment_configuration 的hostname和address欄位為新主機名稱；
1、停庫，關閉維護模式；
2、修改/etc/sysconf/network和/etc/hosts檔案，使用新的主機名稱，重啟主機；
3、開啟資料庫並檢查。

#
# This file consists of lines of the form:

# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.
