1. 脚本
# vim /root/pgback.sh !#/bin/bash cd / back=/home/backup send=`date '+%Y-%m-%d'` pg_dump --dbname="postgresql://127.0.0.1:5432/tenant_1008412?user=postgres&password=csb123456" -F c -b -v -f "$back/tenant_1008412-"$send".backup" pg_dump --dbname="postgresql://127.0.0.1:5432/xw_metadata?user=postgres&password=csb123456" -F c -b -v -f "$back/xw_metadata_1008412-"$send".backup" pg_dump --dbname="postgresql://127.0.0.1:5432/xw_platform?user=postgres&password=csb123456" -F c -b -v -f "$back/xw_platform_1008412-"$send".backup" pg_dump --dbname="postgresql://127.0.0.1:5432/xw_quartz?user=postgres&password=csb123456" -F c -b -v -f "$back/xw_xw_quartz_1008412-"$send".backup"
2. 修改脚本中的 pg 连接，租户库名称，用户密码
chmod +x /root/pg_back之后添加 crontab 作业
3. 定时任务
# crontab -e 1 1 * * * /root/pgback.sh
4. 恢复数据库
#平台库 create database xw_platform with encoding='utf8'; ./pg_restore -U postgres -d xw_platform -v "/usr/local/pgsql/database_backup/xw_platform.20190428.backup" #元数据 create database xw_metadata with encoding='utf8'; ./pg_restore -U postgres -d xw_metadata -v "/usr/local/pgsql/database_backup/xw_metadata.2019042801.backup" #调度库 create database xw_quartz with encoding='utf8'; ./pg_restore -U postgres -d xw_quartz -v "/usr/local/pgsql/database_backup/xw_quartz.20190428.backup" #租户库 create database tenant_1008428 with encoding='utf8'; ./pg_restore -U postgres -d tenant_1008428 -v "/usr/local/pgsql/database_backup/tenant_1008428.20190428.backup"
[root@master ~]# /opt/pg10/bin/pg_restore -h 127.0.0.1 -U postgres -d runoobdb -p31800 -v "/root/runoobdb-2021-03-10.backup"
