👉 本文共约1932个字，系统预计阅读时间或需8分钟。
简介
GPCC 监控系统性能指标，分析集群健康状况，并使数据库管理员能够在 Greenplum Database 环境中执行管理任务。它提供了一个本地浏览器的 HTML5 图形控制台，用于查看 Greenplum Database 系统指标和执行某些数据库管理任务。

安装
在master库上安装即可，客户端会自动安装到其它segment。
root用户做准备工作(必须)
GreenPlum在运行过程中，修改软件的权限为gpadmin.gpadmin并不会引起GPDB的宕机，可以放心修改。
修改所有节点的gpdb的目录权限为gpadmin，否则后续安装gpcc会报错（例如：IOError、gpadmin-[CRITICAL]:-gppkg failed. (Reason='')、Permission denied等）：
1 2 | chown -R gpadmin.gpadmin /usr/local/greenplum-db-6.19.3 chown -R gpadmin.gpadmin /usr/local/greenplum-db |
创建gpcc安装目录：
1 2 3 4 5 6 7 8 | sudo mkdir -p /usr/local/greenplum-cc-6.8.3; chown -R gpadmin:gpadmin /usr/local/greenplum-cc-6.8.3 sudo ln -s /usr/local/greenplum-cc-6.8.3 /usr/local/greenplum-cc -- 或者 source /usr/local/greenplum-db/greenplum_path.sh gpssh -f /home/gpadmin/conf/all_hosts 'sudo mkdir -p /usr/local/greenplum-cc-6.8.3; chown -R gpadmin:gpadmin /usr/local/greenplum-cc-6.8.3' gpssh -f /home/gpadmin/conf/all_hosts 'sudo ln -s /usr/local/greenplum-cc-6.8.3 /usr/local/greenplum-cc' |
配置结果：
1 2 3 4 5 | [root@mdw1 local]# ll lrwxrwxrwx 1 gpadmin gpadmin 29 Jan 12 11:13 greenplum-cc -> /usr/local/greenplum-cc-6.8.3 drwxr-xr-x 12 gpadmin gpadmin 4096 Jan 12 13:40 greenplum-cc-6.8.3 lrwxrwxrwx 1 gpadmin gpadmin 30 Dec 26 18:48 greenplum-db -> /usr/local/greenplum-db-6.19.3 drwxr-xr-x 12 gpadmin gpadmin 4096 Dec 6 12:27 greenplum-db-6.19.3 |

升级extension metrics_collector（必须）
1 2 3 4 5 6 7 | echo 'source /usr/local/greenplum-cc/gpcc_path.sh' >> ~/.bashrc source /usr/local/greenplum-cc/gpcc_path.sh cd $GPCC_HOME cat update-extension.txt |
需要做如下的操作：
1 2 3 4 5 6 7 8 | 1. cd /usr/local/greenplum-cc-6.8.3/gppkg 2. Stop GPCC: gpcc stop 3. Drop extension: psql gpperfmon -c 'drop extension metrics_collector' 4. Use "gppkg -q --all" to list packages installed. 5. Remove the old version of the metrics_collector: "gppkg -r <name>-<version>" 6. Install the new version: gppkg -i MetricsCollector-6.8.3_gp_6.19.3-<OS>-<ARCH>.gppkg 7. Restart GPDB 8. Restart GPCC: gpcc start |
注意：首次安装只需要执行如下的步骤：

若是GPCC安装成功，则会在如下位置有库文件，否则不能随便重启GreenPlum，会导致启动失败：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [root@mdw1 /]# find /usr/local -name metrics_collector* /usr/local/greenplum-db-6.19.3/share/postgresql/extension/metrics_collector--1.0.sql /usr/local/greenplum-db-6.19.3/share/postgresql/extension/metrics_collector.control /usr/local/greenplum-db-6.19.3/lib/postgresql/metrics_collector.so [root@mdw1 /]# [gpadmin@mdw1 ~]$ ll $GPHOME/share/postgresql/extension/gp_wlm* -rw-r--r-- 1 gpadmin gpadmin 856 Dec 6 12:27 /usr/local/greenplum-db-6.19.3/share/postgresql/extension/gp_wlm--0.1.sql -rw-r--r-- 1 gpadmin gpadmin 232 Dec 6 12:27 /usr/local/greenplum-db-6.19.3/share/postgresql/extension/gp_wlm.control [gpadmin@mdw1 ~]$ ll $GPHOME/share/postgresql/extension/metrics_collector* -rw-r--r-- 1 gpadmin gpadmin 846 Dec 6 12:27 /usr/local/greenplum-db-6.19.3/share/postgresql/extension/metrics_collector--1.0.sql -rw-r--r-- 1 gpadmin gpadmin 233 Dec 6 12:27 /usr/local/greenplum-db-6.19.3/share/postgresql/extension/metrics_collector.control [gpadmin@mdw1 ~]$ ll $GPHOME/lib/postgresql/metrics_collector.so -rwxr-xr-x 1 gpadmin gpadmin 3357064 Dec 6 12:27 /usr/local/greenplum-db-6.19.3/lib/postgresql/metrics_collector.so [gpadmin@mdw1 ~]$ [gpadmin@mdw1 ~]$ gppkg -q --all 20230116:14:58:39:020317 gppkg:mdw1:gpadmin-[INFO]:-Starting gppkg with args: -q --all MetricsCollector-6.8.3_gp_6.19.3 |
安装日志

修改用户名和密码：
1 2 3 4 5 | echo '*:5432:gpperfmon:gpmon:lhr' > ~/.pgpass chmod 600 /home/gpadmin/.pgpass psql -d gpperfmon alter user gpmon with password 'lhr'; |
报错解决
1 2 | [newgp@mdw greenplum-cc-web-6.8.3-gp6-rhel7-x86_64]$ ./gpccinstall-6.8.3 -W Failed to connect to database postgres on 152.130.210.107:5432 as newgp: libgssapi_krb5.so: cannot open shared object file: No such file or directory |
分析，查看是否有如下的文件：
1 | ll /usr/lib64/libgssapi_krb5.so |
若没有，则需要安装如下的rpm包：
1 | yum install krb5-libs krb5-devel |
在安装完成后，查询监视器报如下的错误：
Metrics_collector还没有添加到共享预加载库(shared_preload_libraries)中。请添加它以启用指标收集。
必须打开GUC gp_enable_query_metrics来启用指标收集。
修复命令如下所示，在master节点执行：
本人提供Oracle、MySQL、PG等数据库的培训和考证业务，私聊QQ646634621或微信db_bao，谢谢！
1 2 3 4 5 6 7 8 9 10 11 | gpconfig -c shared_preload_libraries -v metrics_collector gpconfig -c gp_enable_query_metrics -v on gpconfig -c track_activities -v on gpconfig -s shared_preload_libraries gpconfig -s gp_enable_query_metrics gpconfig -s track_activities gpstop -M fast ; gpstart -a gpcc stop ; gpcc start ; gpcc status |
在重启GreenPlum后，结果如下才可以：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | [gpadmin@mdw1 gpmetrics]$ gpconfig -s shared_preload_libraries gpconfig -s gp_enable_query_metrics Values on all segments are consistent GUC : shared_preload_libraries Master value: metrics_collector Segment value: metrics_collector [gpadmin@mdw1 gpmetrics]$ gpconfig -s gp_enable_query_metrics Values on all segments are consistent GUC : gp_enable_query_metrics Master value: on Segment value: on [gpadmin@mdw1 gpmetrics]$ gpconfig -s track_activities Values on all segments are consistent GUC : track_activities Master value: on Segment value: on [gpadmin@mdw1 gpmetrics]$ |
注意：该步一定要注意，如果配置不正确，会导致GreenPlum这个不能启动，修复起来比较麻烦。
卸载GPCC
1 2 3 4 5 6 7 8 9 10 11 12 | gpcc --stop rm /usr/local/greenplum-cc ## removes the symbolic link rm -rf /usr/local/greenplum-cc-version gpconfig -c gp_enable_gpperfmon -v off rm -rf $MASTER_DATA_DIRECTORY/gpperfmon/data/* rm -rf $MASTER_DATA_DIRECTORY/gpperfmon/logs/* psql template1 -c 'DROP ROLE gpmon;' dropdb gpperfmon |
若是重新安装相同版本，则不用卸载之前已经安装过的软件。
修改界面为中文
没有直接修改的地方，只能重新安装，重新安装的时候选择中文即可，重新安装之前不需要卸载之前的版本：
1 2 3 4 5 | su - gpadmin source /usr/local/greenplum-db/greenplum_path.sh unzip greenplum-cc-web-6.8.3-gp6-rhel7-x86_64.zip cd greenplum-cc-web-6.8.3-gp6-rhel7-x86_64/ ./gpccinstall-6.8.3 -W |
总结
1、权限一定要对，否则安装会报错
2、安装分为交互式安装和静默安装
3、一定要检验gpcc是否真的安装成功了。
4、GreenPlum在运行过程中，修改软件的权限为gpadmin.gpadmin并不会引起GPDB的宕机，可以放心修改。
